The best door security bars, compared.
Top pick: AceMining door security bar, white, 2 pack Best value: Amazon Basics adjustable security bar, black – Best value at about £19.94 with 4.5 from 3,169 reviews on this ASIN, not a shared colour file. Seat the pins. There is no stated load, and the sliding maximum text is unclear. Updated October 2026.
A door security bar is a metal pole you set inside a door that is already locked. The usual shape runs from a forked head under the lever to a rubber foot, and several listings also say you can lay the pole in a sliding-door track. Ask the Police treats a security door bar as an extra beside a proper lock, and a sliding patio still needs an anti-lift device the bar does not include. Star lines that repeat across colour packs are one trail, not separate tests. How to measure swing, length and floor is in the [door security bar buying guide](/hub/door-and-window-security/door-security-bar/sub/door-security-bar-buying-guide).

Personal buying guide
Question 1 of 2
Which door are you bracing?
The white AceMining 2-pack is two of the same poles, 2.58 kg together, at about £35.99 against about £23.99 for one. Each bullet still says 21–46 inches and 400 pounds. The 4.6 from 12,843 sits on the same review paragraphs as the singles, ten higher on the listing line, and those texts mention a bar on a front door and a back door. Carpet grip and a quick take-off are the praise that repeats. Flex at full extension, outward-door failure, smooth-floor slip and a pin-hole gap around 53–70 cm are the complaints that repeat. The pair costs less than two singles at these shelf prices only when both doors actually lock on a pin. It is not a heavier single bar, and this file says iron while the singles say alloy steel or metal.
Pros
Cons
Best for: Two inward doors you have both measured into a locking hole of this bar.
Less suitable: One door, an outward door, or a second opening that falls in the pin-hole gap.
Specifications
Common questions
What do you pay versus two singles?
This pack is about £35.99. Each white or black 1-pack is about £23.99, so two singles would be about £47.98 at those shelf prices.
Is the review count for the pair?
The listing says 4.6 from 12,843. The paragraphs match the 1-pack files, which say 12,833. Treat it as one shared text, not a separate test of the pair.
When is a pair the wrong buy?
If the two doors are not both inside a locking hole of the 21–46 inch bullet. Reviews say outward doors fail and that about 53 cm to 70 cm has no lock position.
The white AceMining 1-pack is about £23.99. The bullet says 21–46 inches, a 1.57 inch pipe and 400 pounds. The specification weight is 998 g, while the bullet says 2.2 pounds. It is 4.6 from 12,833 reviews, and those paragraphs are repeated on the other AceMining ASINs in this folder. Buyers like the night-time brace on carpet. They report flex at full stretch, a pin-hole gap, outward-door failure, laminate slip, and a pole that is too heavy to fly with.
Pros
Cons
Best for: An inward door whose locked hole you have checked, if you want the single white pole and you will not travel with it.
Less suitable: An outward door, a laminate floor, a sliding gap between the pin holes, or a flight.
Specifications
Common questions
How long is it, really?
The bullet says 21–46 inches, about 53–117 cm. A review says the first lock is about 53 cm and the next is about 70 cm, so openings between those holes do not lock.
Does it work on an outward-opening door?
Reviews say no. It is used on the inside of an inward-opening door.
Why is the review count not the decider?
The listing says 4.6 from 12,833. The same paragraphs are in the black 1-pack and the white 2-pack files. Flex, laminate slip and travel weight are in that shared text.
The black AceMining single is the same about £23.99 brace as the white 1-pack, with a Y-cap under the handle, a bullet range of 21–46 inches (about 53–117 cm) and a 400 pound claim. The model line is SecurityBar001-Black-1Pack-A and the weight line is 1.32 kg, which does not match the white file’s 998 g or the 2.2 pound bullet. The 4.6 from 12,833 reviews is those same paragraphs, not a separate test of the black tube. Buyers brace it at night on carpet and take it off quickly when the foot sits flat. They also report flex at full stretch, a lock-hole gap around 53–70 cm, failure on outward doors, slip on laminate, and a pole that is too heavy to fly with. Included parts are not listed on this file. Check that a locking hole meets your handle before you buy black for the colour.
Pros
Cons
Best for: You want the black single pole and you have checked a locking hole against your handle.
Less suitable: You thought the 12,833 reviews were a second test, or you need a listed kit of parts.
Specifications
Common questions
How does the weight compare with the white 1-pack?
This listing says 1.32 kg. The white 1-pack says 998 g. The shared bullet says 2.2 pounds. The listings do not explain the difference.
Are the reviews separate?
The paragraphs in this file match the white 1-pack, and the count is the same 12,833.
What is in the box?
This listing has no included-components line. The white 1-pack lists a rubber cap, the bar, a manual and a Y-type cap.
Pindex is a 730 g telescopic brace with a Y-shaped head and a rotating rubber foot, stated at 110–140 cm, at about £16.99 on amazon.co.uk. The indoor reviews describe setting it under a bedroom handle at night without drilling the frame. The 4.6 comes from 12 reviews, and the extract only has five texts, so there is no defect pattern you can treat as settled. One buyer tried a patio and a front door and only one of them fitted. The box lists pins, spring buttons and mounting hardware, so the questions’ no-tools line is not an empty kit. There is no kilogram load, only a strong-resistance phrase. If both openings are not inside 110–140 cm, this is already the listing that missed one of two doors.
Pros
Cons
Best for: An inswing or sliding opening you have measured inside 110–140 cm, if you can return it when it misses.
Less suitable: You need a large UK review trail, or you have two different doors and only one measurement.
Specifications
Common questions
What length does the listing state?
110–140 cm, also written as 1.1–1.4 m in the title.
Does it need tools?
The questions at the top of the listing say no. The included-components line lists pins, spring buttons and mounting hardware. Reviews describe a bedroom bar with no installation.
How many reviews are behind the 4.6?
The listing says 12. Five review texts are printed with it. One says it fitted one of two doors.
Amazon Basics AB-DH303-BK is about £19.94, powder-coated steel, 73.6–114 cm, with a removable head for a sliding door. It is 4.5 from 3,169 reviews, the largest count in this set that is not copied across colour packs. There is no kilogram load. ANSI has no number. Reviews praise the price and complain about pins, wobble and smooth floors. It is the best value in this set if your handle sits in that range and you seat the pins before you trust it.
Pros
Cons
Best for: A hinged door inside 73.6–114 cm, or a slider where the removable head actually reaches, at a mid price with a long review trail.
Less suitable: You need a named load, a PAS 24 claim, or a bar whose pins stay put without careful handling.
Specifications
Common questions
How far does it adjust?
The bullet says 73.6–114 cm. The sliding-door maximum is printed as an unclear 104-7.6 cm/10 cm, so the sliding length is not a clean figure.
Does it include a lock?
The listing asks and does not answer. The bullets list a removable head and a rubber foot, not a keyed lock.
What fails in reviews?
Pins pop out if you lean on the bar, joints feel loose, it slips on tiles, and the fork can leave the handle free to turn. One unit arrived cracked.
Defender HA00721, made for the listing by Solon Security, is about £21.95, 73–113 cm, 590 g, and 4.5 from 1,047 reviews on this ASIN. The listing names hinged and sliding doors and seven floor types, and it claims 250 kg. Reviews describe a kick-in fit, rental use, and push tests that held. They also describe laminate slip, a plastic foot bolt that makes the 250 kg line hard to believe, keys that block the yoke, and patios that are too short or slide the wrong way. It is the top pick in this set when the handle is inside 73–113 cm and you treat the load line as a claim.
Pros
Cons
Best for: An inswing lever inside 73–113 cm, or a slider you have measured, if you can kick the foot in and get it off again.
Less suitable: A door with a bulky thumbturn, a smooth floor you will not add grip to, or a patio that slides on the outside.
Specifications
Common questions
What length and weight does the listing state?
73–113 cm working length, and 590 g. The 11.2 x 6 x 6 cm line is the packed size, not the working length.
Which floors does the listing name?
Laminate, lino, vinyl, wood, marble, carpet and concrete. Reviews include a firm hold on carpet and tile, and slip on laminate until a carpet tile was added.
What blocks the yoke?
A key left in the lock, or a thumbturn, stops the fork sitting tight. Taking the fork off for a patio can launch small springs.
DoorJammer DJ3 is about £22.72, 210 g, red, and 4.4 from 2,799 reviews. It is an under-door brace for inswing doors, not a telescopic bar, so it sits in this set only as the travel-weight alternative. Reviews use it in hotels and rented rooms where drilling is not allowed. Fit fails when the gap is too small. One screw would not turn. Removal is a pull, which one reviewer said could be hard from the floor. The listing says about 3 mm clearance. Secured by Design lists DoorJammer against relative clauses of PAS 24. That entry does not cover the telescopic bars here.
Pros
Cons
Best for: A hotel, dorm or bedroom door that opens in, with a clear gap under the door, when you will not carry a 1 kg pole.
Less suitable: A sliding patio, an outward door, a sealed UK front door, or anyone who wanted a handle-to-floor bar.
Specifications
Common questions
Is this a door security bar?
No. It is a 210 g plate that jams under an inswing door. The listing says about 3 mm clearance. It does not span from the floor to the handle.
What gap do you need?
The listing says about 3 mm, also written as 1/4 inch. One review at that minimum still could not fit it and suggested about 5 mm. Weather seals are a known miss on the maker’s own pages.
What does the PAS 24 line mean here?
The Amazon bullet says a PAS 24 impact test and police accreditation. That is a listing claim. It is not a certificate for your door, and it does not apply to the telescopic bars in this comparison.
The black eSynic is a three-stage brace you lengthen with a button, stated at 84–113 cm, for about £18.49. Buyers inside that range describe a quick fit and use it at night in a student flat, or on a back door after break-ins nearby. The 4.4 from 308 reviews is the same text as the white eSynic file, so it is one trail rather than two colours tested apart. The listing claims 250 kg. Reviews do not treat that figure as settled: plastic joint caps fall out, the three sections develop play, and the tube feels flimsy once it is joined. The padded foot still slips for some people, and the bar comes back too short for stepped thresholds and some patio doors. Kick it in tight if the length matches, and read 250 kg as a seller claim.
Pros
Cons
Best for: An inswing handle inside 84–113 cm if you will check the plastic joints before you rely on it.
Less suitable: A stepped threshold, a patio wider than the bar, or anyone treating 250 kg as a lab result.
Specifications
Common questions
What length and load does the listing state?
84–113 cm, and 250 kg. The 250 kg figure is a listing claim. There is no test report on the listing.
Does it need tools?
The bullet says no tools. You press a release button. It arrives in three sections.
What do reviews say about stiffness?
Many call it easy and solid. Others say plastic caps fall out, the sections have too much play, and it was too short for a stepped door.
The white eSynic ESYHG903 is the same three-stage brace as the black listing, at the same about £18.49, stated at 84–113 cm with a 250 kg claim. This specification line puts the weight at 1 kg, against 1.27 kg on the black file, and it does not list what is in the box. The 4.4 from 308 is the same review paragraphs, including student-flat use and use after local break-ins. Shared complaints are flex, plastic caps that fall out, a foot that slips, and a bar that is too short for some patios and stepped doors. One shared note wished for white on a patio because black showed, which is a colour preference, not a second test. A buyer who found the joined tube flimsy started a return. Measure 84–113 cm on your own door before you choose white at the same price.
Pros
Cons
Best for: You want the white tube at the same price, after you have measured 84–113 cm.
Less suitable: You wanted a second, independent set of reviews, or a door outside that range.
Specifications
Common questions
How is this different from the black eSynic?
This listing is white, model ESYHG903, at 1 kg and about £18.49. The black listing is 1.27 kg. Both say 84–113 cm and 250 kg, and both carry the same review paragraphs and the same 308 count.
What load does it claim?
250 kg, as a listing claim. Reviews still call some samples flimsy when the sections are joined.
Will it fit a stepped door?
Shared reviews say it was too short for a stepped door even fully extended, and wrong for two different patio widths.
The black 44–55 inch bar is about £12.99 with a 4.4 from 32 reviews on the listing line. Those review paragraphs are the same text as the white twin. It is a 710 g iron tube with a rubber base and no stated load. Buyers both brace a door and prop a patio door open. One review doubts the light tube. The listing does not name a brand. It is the low shelf price in this set, not the best value, because the review trail is thin and shared.
Pros
Cons
Best for: A low shelf price if you have measured a long opening and you accept a thin review trail.
Less suitable: Anyone who needs a stated load, a proven inswing brace, or a bar that is not also being used as a door stop.
Specifications
Common questions
How long is this bar?
The title says 44–55 inches, about 112–140 cm. The bullet says it can be adjusted to 55 inches. Packed size on the listing is 41.5 x 11 x 5 cm.
Does the listing state a load?
No load figure is printed. One review calls the tube light and doubts it would resist a small push.
Is it only a security bar?
The title says security bar. Several of the review texts use it to hold a patio door open in a breeze.
The white bar screws into a 44–55 inch brace, about 112–140 cm, and the amazon.co.uk shelf price is about £14.99. The 4.4 from 32 reviews uses the same paragraphs as the black twin, and several of those texts praise holding a patio door open in a breeze rather than resisting a push. It is a 710 g iron tube with a rubber base and no stated load. One shared review doubts the light tube would stop even a small shove, and another fears the rubber will skate on a wood floor. A further review says the box had no instructions. You pay about £2 more than the black listing for the white finish, not for a separate set of tests. The listing does not name a brand.
Pros
Cons
Best for: You want the white tube and you have checked 112–140 cm against the opening.
Less suitable: You want a separate review history from the black listing, or a stated load.
Specifications
Common questions
How long is this bar?
The title says 44–55 inches. The bullet says adjustable to 55 inches. The specification block lists 41.5 x 11 x 5 cm and 710 g.
Will it stop forced entry?
The listing does not state a load. One of the shared reviews doubts the lightweight tube would sustain even a minimal push.
Are there instructions?
One review says there were no instructions, but the sections screwed together.
HOMGEN HOGHG965 is a 1.1 kg iron bar in three sections that clips under an inward handle, with a moving foot you use to tighten the fit, at about £21.37. The stated range is 84–113 cm and the title carries a 250 kg claim. It is 4.2 from 240 reviews, the lowest star line in this set. Once the parts are together, some buyers find it thick and easy to take off, including on a side door that has no lock of its own. At full extension the same reviews call it wobbly, and a UK composite only reached on the last holes, with a miss above about 100 cm. A hard push slid the foot on laminate, a lift handle knocked the bar off, and one door still opened from outside. Daily use is described without screws, though one buyer needed a flat screwdriver to assemble it on arrival.
Pros
Cons
Best for: An inward handle comfortably inside 84–113 cm, not at the last hole.
Less suitable: A tall UK handle, an outward door, a lift handle, or laminate if you cannot add grip.
Specifications
Common questions
Which doors does the listing name?
Inward-opening hinged doors, a single-handle French door, patio and sliding doors, and sliding windows. Reviews add that outward doors and a conservatory lift handle are a miss.
What happens at full extension?
More than one review says it is wobbly or useless when fully extended. One says a handle more than about 100 cm from the floor was too high. Another says a normal home was too tall.
Is 250 kg tested here?
It is in the title. No report is on the listing. Reviews include a hard push that slid the foot on laminate, and one that says the door still opened from outside.
The twelve cards use the amazon.co.uk listing lines in this folder: shelf price, stated length, star rating and the review notes already on each card. There is no laboratory test. A 250 kg or 400 lb line is a seller claim, not a measured result. Star lines that share the same review paragraphs across colour packs count as one trail. The mark on each card is that listing’s star line on a scale of 10. The top pick is the Defender HA00721: a long review file on this ASIN, a stated 73–113 cm range and named floor types, with the load line left as a claim. The best value is the Amazon Basics AB-DH303-BK at about £19.94, with 3,169 reviews that are not copied across a colour pack, if you seat the pins. The about £12.99 bar does not take that award. It has 32 reviews shared with the white twin and no stated load. One of each award. The weights below sum to 100.
Measured fit
30%Swing and door type first, then a stated length you can check against the handle or the track. Pin holes are not a continuous range. An outswing door, or a length that only reaches on the last hole, scores down.
Amazon evidence
25%The star rating on amazon.co.uk, then a deduction when the count is a handful or the same paragraphs are repeated on another ASIN. A 4.6 from a shared 12,000-plus line does not outrank 4.5 from 1,047 reviews on one listing.
Floor and joints
20%A named foot and reviews that describe grip, set against reviews of slip, pins that pop out, plastic caps that fall off, or a tube that flexes at full extension. A listing that names seven floors still loses points where laminate slip is in the reviews.
Claims and limits
15%A stated load stays a seller claim unless a report is in the file. None is. A missing load is recorded as missing. A PAS 24 line is kept to the DoorJammer listing and is not copied to the telescopic bars.
Value
10%Shelf price in GBP against a bar whose review file belongs to that ASIN and whose length you can check. About £19.94 with 3,169 reviews on this listing takes the best-value award. A lower shelf price does not, when the written file is thin and shared.
Choose the door and the job before the finish. A handle-to-floor brace on an inswing lever is a different purchase from a 210 g under-door plate, and neither replaces the lock you use when you leave. The notes below follow the twelve amazon.co.uk listings in this comparison and the public UK sources named at the end of this page. There was no laboratory test. A 250 kg or 400 lb line is a seller claim.
A door security bar, in UK shopping, is a metal pole you set inside a door as extra resistance after the door is already locked. The usual shape runs from a forked head under the lever to a rubber foot. Several listings also say you can lay the pole in a sliding-door track, usually with the yoke removed. Ask the Police treats a security door bar as an extra beside a proper lock, and says to check an anti-lift device on a sliding patio so the door cannot be lifted out.
AceMining’s 4.6 from 12,833 and 12,843, both eSynic 4.4 from 308 lines, and both unbranded 4.4 from 32 lines repeat the same review text across colours. That is one trail, not two or three tests.
250 kg on Defender, eSynic and HOMGEN, and 400 lb on AceMining, are seller claims. No UKAS report is in these extracts. Reviews still describe flex, pins that pop out, and a plastic foot bolt.
Several reviews of the 44–55 inch listings praise holding a patio door open in a breeze. That is a door stop. It is not the night brace this page is comparing.
A handle-to-floor brace and the DoorJammer are for inswing doors. Outswing doors are the mismatch reviewers report on AceMining and on HOMGEN, and a lift handle can knock a bar off. Sliding doors need the pole in the track, usually with the yoke removed, and they still need an anti-lift device the bar does not include. Some Defender patios came back because the door slid the wrong way. Measure finished floor to the underside of the lever, not the headline range. Pin holes skip lengths.
250 kg on Defender, eSynic and HOMGEN, and 400 lb on AceMining, are seller claims. No UKAS report is in the listings. A Defender review points at a plastic foot bolt and finds the 250 kg line hard to believe. Amazon Basics names ANSI with no number and states no kilogram load. The unbranded bars and the Pindex also state no load. PAS 24 on the DoorJammer bullet, and the Secured by Design entry for relative clauses, belong to that 210 g plate. They do not transfer to the telescopic bars.
Three typical situations, each with a recommendation from this comparison.
You need a brace that does not drill the frame, and you still lock the door. The Defender HA00721 is the top pick at about £21.95 if the lever sits inside 73–113 cm. Reviews describe rental use and a kick-in fit. A thumbturn or a key left in the lock can block the yoke, and laminate can still slip.
You want a hinged door inside 73.6–114 cm, or a slider where the removable head reaches, without paying for a shared star line. The Amazon Basics AB-DH303-BK is the best value at about £19.94, with 4.5 from 3,169 reviews on this ASIN. Seat the pins. There is no kilogram load, and the sliding maximum text is unclear.
You will not carry a pole of about 1 kg, and the door opens in with a clear gap underneath. The DoorJammer DJ3 is 210 g at about £22.72, with 4.4 from 2,799 reviews. It is an under-door plate, not a handle-to-floor bar. A seal or a gap near 3 mm can stop it.
The Defender HA00721 is the top pick. It has 4.5 from 1,047 reviews on this ASIN, a stated 73–113 cm range, named floor types and no drill, at about £21.95. The 250 kg line stays a seller claim, and reviews already describe laminate slip and a yoke blocked by a key or a thumbturn. The Amazon Basics AB-DH303-BK is the best value at about £19.94, with 4.5 from 3,169 reviews that are not a colour-pack copy, if the handle sits in 73.6–114 cm and you seat the pins. The about £12.99 bar is cheaper and does not take that award: 32 shared reviews and no stated load. None of the twelve replaces the lock, and none of the telescopic bars is PAS 24.
Amazon Basics adjustable security bar, black
Best value at about £19.94 with 4.5 from 3,169 reviews on this ASIN, not a shared colour file. Seat the pins. There is no stated load, and the sliding maximum text is unclear.
