Top pick: the Defender HA00721

The Defender HA00721 is the top pick for a measured inswing door. On 19 October 2026 amazon.co.uk showed about £21.95, 4.5 from 1,047 reviews on this ASIN, 73–113 cm and 590 g. It suits a renter who will not drill the frame, if the door already locks and the bar comes off from inside. Skip it when a thumbturn or a key in the cylinder blocks the fork. The listing names laminate, lino, vinyl, wood, marble, carpet and concrete, yet reviews describe the foot skating on laminate. A clear lever 95 cm off bare concrete is the case it is for. If the tape reads 120 cm, use the door security bar buying guide.

Best value: the Amazon Basics bar

The best value is the Amazon Basics AB-DH303-BK at about £19.94, with 4.5 from 3,169 reviews and a stated range of 73.6–114 cm. Open it when the handle sits in that band and you push the pins fully home. Skip it if you need a stated load. An ANSI mention with no standard number is not a test you can cite. Pin holes are steps, so a handle at 90 cm can fall between two holes. Reviewers report slip on smooth floors, and no sliding-track maximum is stated. On short carpet, with the pins seated, it sits beside the Defender. The extra pound or two does not buy a verified load.

Why the biggest star count is not the winner

AceMining is the trap if you sort by stars. One pack shows 4.6 from 12,833 reviews and another 4.6 from 12,843, with the same text shared. That is not three tests. The seller states 400 lb, and no UKAS report is in the extracts. One review puts a hole near 53 cm and the next near 70 cm, inside a stated range of about 53–117 cm. Reviewers also describe flex, pins that pop out, and a pole of about 1–1.3 kg that was too heavy to fly with. A single was about £23.99 and the two-pack about £35.99. HOMGEN at about £21.37 is 4.2 from 240 reviews. eSynic repeats 4.4 from 308 across colours, and LuLobtg 4.4 from 32.

When neither pick is the right object

An outward-opening door is the first skip. These braces are for inswing leaves. Travel is the second. The DoorJammer DJ3 is about 210 g, needs roughly 3 mm of clearance, and the maker warns about weather seals. Secured by Design lists it against relative clauses of PAS 24, which does not cover these poles. The split is on the door security bar versus portable jammer page. A sliding patio is the third skip. A pole in the track does not stop a lift-out. The sliding door security bar page keeps the anti-lift separate. Do not screw into a flat entrance fire door.

Common questions

Is the Defender’s 250 kg figure proven?
No. The 250 kg line on the Defender HA00721 is the seller’s claim, and HOMGEN prints the same figure. Extracts from 19 October 2026 contain no UKAS report, and this set was not load-tested. AceMining’s 400 lb claim sits in the same place. Match the length to your handle, and use a review count for that listing. The kilogram figure is not proof the brace is safer.
What if my handle is taller than 113 cm?
Skip the Defender once the underside of the lever is above 113 cm. The Amazon Basics bar stops at a stated 114 cm, so it does not suit a taller door either. Pindex, listed at 110–140 cm, is the longer bar in this set, and only if you accept 4.6 stars from 12 reviews. Measure the lever rather than trusting the headline range alone.
Is the DoorJammer the best door security bar?
Not for a home lever around 90 cm. The DoorJammer DJ3 is about 210 g, needs roughly 3 mm of clearance, and the maker warns about weather seals. A Secured by Design note against relative clauses of PAS 24 does not cover the telescopic braces here. Use the plate for a hotel, or a room with no useful lever, and only when the door opens in.
What should I skip if the door opens outwards?
Skip the handle-to-floor braces and the DoorJammer. Both are for doors that swing in, and reviewers describe the mismatch on an outward-opening leaf. A lower price or a 4.5-star line does not change the swing. If you rent and cannot replace the door, this category is the wrong extra. Call a locksmith if the lock you already have is failing.
Do I still need the door’s own lock?
Yes. Ask the Police treats a security door bar as an extra beside that lock, not as a replacement. None of the telescopic bars here is BS 3621, PAS 24 or Sold Secure. Lock the door, then set the brace, and do not drill a flat entrance fire door. You also need to remove the bar quickly from inside.

Public UK sources from the research digest, used for this page in October 2026. Prices, stars and review counts are the amazon.co.uk figures in the listing extracts. Defender’s amazon.co.uk page and the DoorJammer UK site still matched on 19 October 2026. A 250 kg or 400 lb line is a seller claim. PAS 24 is quoted only for the DoorJammer listing and the Secured by Design entry, not for the telescopic bars.
