The best plastic wedges, compared.
Top pick: Xinnjie 60 mixed plastic wedges Best value: HongNuoEn 50 mixed plastic wedges – About £6.99 for 50 pieces in two stated sizes, score 75, with its own six reviews. About 14p a stated piece. Updated 23 October 2026.
Plastic wedges are tapered packers for a small gap. In the UK you buy one to stop a table, wardrobe or chair from rocking, to take the rattle out of a sound fence panel, or to pack beside a frame. It is not a flat installation packer, and it is not a substitute for the packers named on a window system. The checks that still apply when the box changes are the gap in millimetres, the shape, and whether the title size matches the specification. Furniture wedges are usually short, about 48–80 mm long and only a few millimetres thick. A fence wedge is narrower and thicker. A glazing wedge is much longer. A rib, a stack or a snap line is a claim until you try the piece. A load sentence with no report is not a safe working load. Measure the gap, then read the piece count against the item line. The order of those checks is in the [plastic wedges buying guide](/hub/diy-supplies/plastic-wedges/sub/plastic-wedges-buying-guide).

Personal buying guide
Question 1 of 2
Where does the gap sit?
Xinnjie lists 60 black wedges in two sizes for £7.19, with 5.0 from 2 reviews. The bullets claim a textured face, stacking, and cutting, plus indoor and outdoor use. The only jobs named in UK reviews are a container pond and a wedge carried for a pub table. The thickness field records 6 mm and ignores the 8 mm pieces. There is no load figure, despite a customer question about weight. Two reviews are not a basis for a badge.
Pros
Cons
Best for: You want a two-size black box and you do not need a large review file.
Less suitable: You want the score leader or a pack whose thickness field matches every piece.
Specifications
Common questions
What is in the 60-piece set?
The bullets say 30 pieces at 60 × 26 × 6–1 mm and 30 at 80 × 30 × 8–1 mm. The thickness field on its own says 6 mm.
Can they be cut or stacked?
The bullets say you can stack them or cut them. Neither UK review describes a cut.
What did UK reviewers use them for?
One levelled a container pond and keeps a piece for a wobbly table. The other says the quality is good. The star line is 5.0 from 2 reviews.
HongNuoEn lists 50 black wedges for £6.99, with 4.8 from 6 reviews. The bullets split them into 30 smaller and 20 larger pieces. One UK review used them under composite decking, noted the thin leading edge and the grip, and said none broke. The specification line does not label length, width, and thickness the way the bullets do. Six reviews are a small file, and there is no tested load. It is the best value in this set on stated pieces per pound among packs with their own UK notes.
Pros
Cons
Best for: You want a mixed box of short black wedges for furniture or deck supports and you can accept a six-review file.
Less suitable: You need a measured fence wedge, a long snap shim, or a large independent review file.
Specifications
Common questions
What sizes are in the 50-pack?
The bullets say 30 pieces at 60 × 26 × 6 mm and 20 at 80 × 30 × 8 mm. The specification line says 8 × 0.8 × 3 cm and does not use those axis labels.
Can they be cut?
One UK review says they can be cut to size and were used under composite decking. The bullets do not mention a snap line.
Do the reviews mention a fault?
The four UK texts praise consistent spacers, two sizes, grip, and a decking job. None of them states a defect. The star line is 4.8 from 6 reviews.
SUMNACON lists 60 black shims at 60 × 26 × 6 mm for £8.99. The star line is 4.7 from 69, and the UK texts are the same as on the 120-pack. Those texts mention vinyl flooring, decking on concrete, and Ikea wardrobes. The pack weight is 300 g, against 660 g on the 120-pack, so the boxes are not the same object. The unit count says 1.0 gram and the item type says Chaises Longues. Count the reviews once.
Pros
Cons
Best for: You want about 60 pieces of one 60 × 26 mm size and you will not treat the 69 reviews as unique to this box.
Less suitable: You want an independent review file or a listing whose unit count matches the pack.
Specifications
Common questions
Is the 69-review line only for this 60-pack?
The file prints 4.7 from 69, and the UK paragraphs match the 120-pack file, which prints the same count. Treat it as one shared pool.
What size is stated?
The title and the dimension line say 6 × 2.6 × 0.6 cm. The unit count says 1.0 gram and the number of items says 1, against 60 pieces.
What jobs appear in the reviews?
The shared UK texts mention vinyl click flooring, decking shims on concrete, and Ikea wardrobes. They do not state a fault.
The 120-pack is £10.99 for the same stated 60 × 26 × 6 mm shim as the 60-pack. The star line and the UK paragraphs are the same 4.7 from 69. Extra clashes are a grip-material line that says Rubber and a unit count of 1.0 gram. The higher pack weight is the clearest sign in the file that more pieces are in the box. It does not earn a separate review sample.
Pros
Cons
Best for: You specifically want about 120 pieces of this one size and you already know the reviews are shared.
Less suitable: You want a unique review file or the lower price of the 60-pack of the same stated size.
Specifications
Common questions
How is this different from the 60-pack?
The piece count is 120 against 60, the model is YG0384 against YG0383, and the pack weight is 660 g against 300 g. The UK review texts and the 69-review count match.
Does the grip field say rubber?
The grip-material field says Rubber. The material line says Plastic. A bullet claims an anti-slip texture. There is no material test in the file.
What do the shared reviews mention?
Vinyl click flooring, decking shims on a concrete base, and Ikea wardrobes on an uneven floor. They do not state a fault.
Lokatall lists eight red wedge spacers at £9.99, with 4.5 from 16 reviews. The length, about 175 mm, is the figure that repeats. Thickness does not. A bullet claims up to 30 tons and another says you can overlap the wedges or invert them into a flat plate. The only UK review text is two words. This is the glazing-sized wedge in the set, not a tested installation packer and not a furniture shim.
Pros
Cons
Best for: You want a long red wedge spacer and you will measure the thickness yourself.
Less suitable: You need a flat colour-coded glazing packer, a proved load, or a furniture wedge you can hide.
Specifications
Common questions
How thick is each wedge?
The title says from 1 mm to 30 mm. A bullet says 35 mm. The size line says 175 mm by 30 mm. The product dimensions are 17.5 × 3 × 3.5 cm. The length is the stable figure. The thickness is not.
Does the file prove a 30 ton load?
A bullet says optimal load transfer up to 30 tons. The file contains no test report. Do not use that sentence as a safe working load.
What do the reviews say?
The star line is 4.5 from 16. The only UK review text in the file says good product and does not describe a window.
Mistillion lists 15 white PP shims at £6.09, with 4.5 from 2 reviews. The bullets describe a 0.6–6 mm taper, a textured face, and stacking without tools. The specification line and the square shape field disagree with that bullet. The only UK review mentions rollers. Brand and manufacturer also differ: Mistillion and KaCrypto. Do not treat the star line as confirmation of the wedge.
Pros
Cons
Best for: You can measure a white 51 mm shim on arrival and you only need the bullet taper if it matches.
Less suitable: You want a review that describes these shims, or a single size line.
Specifications
Common questions
Which size line should you trust?
The bullets say 51 mm by 30 mm, tapering from 0.6 mm to 6 mm. The specification says 30 × 5 × 50 mm and the shape says Square. Measure on arrival.
What does the UK review say?
The only UK text calls the product good value and then talks about rollers on different surfaces. This listing is a shim pack, so that sentence does not describe the wedges.
Is a warranty stated?
A bullet claims a 24-month warranty against material and workmanship, and the spare-part field says 24 months. The file has no warranty terms beyond that sentence.
This 10-pack is listed at £4.59 with 4.4 from 56 amazon.co.uk reviews, the largest review file in the set. UK buyers describe a wonky table, a stacked wardrobe, a small birdbath, and an integrated washing machine. The bullet size is 30 × 50 × 6 mm, and one UK reviewer measured that thick end. Another called them wafer thin against the photograph. The title also says glazing packers, and the included-components field says NO. There is no tested load. It is the top pick for a few millimetres under sound furniture when you have checked that 6 mm, stacked if needed, is enough.
Pros
Cons
Best for: You need a few millimetres under a table, cabinet, or wardrobe and you want the largest UK review file in this set.
Less suitable: You need a fence-slot wedge, a glazing packer, or a rise well above 6 mm without stacking.
Specifications
Common questions
How thick are these wedges?
The bullet says 3 × 5 × 0.6 cm. A UK reviewer measured 5 cm by 3 cm by 0.6 cm at the thick end. Another UK review expected a much thicker wedge than the photograph showed.
Can they be stacked?
The bullets say you can stack them to raise a table or sofa. UK reviews describe stacking to reach the height needed, including under a wardrobe.
Are they glazing packers?
The title says glazing packers. The UK reviews in the file describe furniture, a birdbath, and a washing machine. The file has no glazing method.
CRCFSUK lists four transparent wedges at £4.19, stated at 48 × 30 × 10 mm, with 4.0 from 25 reviews. UK reviews say the size is accurate, the pieces are smaller than a normal door stop, ridges help under a tight door, and carpet was a poor surface. The listing names rubber, PVC, and plastic. German-language reviews in the file are not used as UK opinion. It is a small-gap door or furniture wedge, not a fence or glazing part.
Pros
Cons
Best for: You have measured a gap around 10 mm or less and you want a clear wedge, including a tight door.
Less suitable: You need a normal door stop, carpet grip, or more than a handful of pieces.
Specifications
Common questions
Are they big enough for a door?
UK reviews say they are much smaller than a standard door stop and that the printed 48 × 30 × 10 mm size is accurate. They suited a very tight gap. One reviewer needed two together.
Do they grip carpet?
One UK review tried a carpeted floor and did not find them effective. The same review said the ridges held a hard-floor door gap.
Are they rubber or plastic?
The title says rubber and plastic. A bullet says PVC. The material line says Plastic. The file does not include a material test.
Onspeshow lists 12 composite shims at £14.99, each stated at 8 inches long, with pre-scored snap lines and a waterproof claim. There is no star line and no review text. The size is in inches only. It is the long shim in this set, at the highest price, and the snap feature is a seller sentence until you try one piece.
Pros
Cons
Best for: You want a long snap shim and you can check the first piece before you rely on the score lines.
Less suitable: You want UK reviews, a millimetre size, or a cheap short wedge.
Specifications
Common questions
Can they be snapped?
The bullets say pre-scored lines let you snap a shim by hand. The file has no review that confirms a snap, and no star line.
What load do they state?
A customer question asks how much weight they hold. The file gives no figure. A heavy-duty sentence is not a test.
Are the sizes in millimetres?
The file gives 8 inches by 1.5 inches, a 0.275 inch base, and a taper from 5/16 inch to 1/16 inch. It does not print a millimetre line. The pack weight is 260 g.
GengHeXIN lists 20 fence wedges at £6.59, stated at 82 × 20 × 15 mm, for wind rattle between a panel and a post. The bullets also mention windows, doors, and tiles. There is no star line. The unit count says 1.0 count. The pack weight is 20 g. It is the only fence-shaped wedge in the set, and the file does not show whether buyers found it tight in a concrete slot.
Pros
Cons
Best for: You have a sound panel in a slot and you want a wedge around 15 mm thick rather than a furniture shim.
Less suitable: You need UK reviews, or the post itself is loose.
Specifications
Common questions
What size is each fence wedge?
The bullets and the dimension line say 8.2 × 2 × 1.5 cm. The pack weight is 20 g for a stated 20 pieces. There is no review to confirm either figure.
How many does the file say to use per panel?
A customer question asks. The bullets say to insert wedges between panel and post and to stack them for a wider gap. They do not give a number per panel.
Is there a star rating?
This file has no star line and no review text. The best-sellers line places it at 25 in Posts.
The Generic 10-pack is £4.88. The title promises 50 × 30 × 5 mm flexible shims for tables and cabinets. The specification promises 90 × 50 × 10 mm. Nothing in the file tells you which box arrives, and there are no reviews. Stacking and a textured face are claimed. Buy it only if you can return a size that does not match the line you used.
Pros
Cons
Best for: You have checked both size lines and you are willing to measure and return.
Less suitable: You need one agreed size before you order.
Specifications
Common questions
Which size is in the listing?
The title says 50 × 30 × 5 mm. The specification says 9 × 5 × 1 cm. Those are not the same piece. Measure on arrival.
Can they be stacked?
A bullet says you can stack them and slide the tapered end under a foot, without drilling. There is no review.
Is there a rating?
The file has no star line and no review text. The price in the file is £4.88.
Buwoek lists white levelling wedges at £8.99. The title says 20 pieces and the item line says 40. The specification is 50 × 30 × 5 mm, and a bullet describes a 2–5 mm taper plus interlocking pegs and a trim groove. There is no star line, no review, and no best-sellers rank. The price is high for an unresolved count. Measure the contents if you order it.
Pros
Cons
Best for: You want the interlocking claim and you will count the pieces on arrival.
Less suitable: You need a known piece count before you pay £8.99.
Specifications
Common questions
Is it a 20-pack or a 40-pack?
The title says 20. The number-of-items line says 40. The file does not explain the difference. There is no review.
Do the pieces lock together?
A bullet says interlocking pegs and recesses. Nothing in the file confirms that on a real floor.
What taper is stated?
The specification thickness is 0.5 cm. A bullet says the taper runs from about 0.2 cm to 0.5 cm. The pack weight is 230 g.
Shelf prices, stars and review notes are the twelve amazon.co.uk listings stored for this set, read on 21 October 2026. This is not a lab test of load, creep, grip or weather. Each score adds a star line, multiplied by eight and rounded, a mark for the size of that review sample, listing clarity from a start of 28, and a mark for UK review notes. A 5.0 from two reviews does not outrank a larger file on stars alone. The two packs that share one 69-review text are not two British samples. German-language reviews are not UK opinion. The highest score, 78, is the top pick. Best value is a separate award: stated pieces per pound on a pack with its own UK notes, not the lowest price and not the shared review pool.
Star line
44%The amazon.co.uk star line is multiplied by eight and rounded. A 4.4 becomes 35, a 4.8 becomes 38, and a 5.0 becomes 40. A file with no star line scores 0 on this block. Stars are not the whole score.
Review sample
9%The count on that file adds 8 from 50 to 199 reviews, 4 from 6 to 49, 2 from 5 or fewer, and 0 if the file has no count. No file in this set has 200 or more reviews. A thin sample cannot outrank a larger one on stars alone.
Listing clarity
31%Clarity starts at 28 and loses marks when the unit count fights the pack, the title size fights the specification, thickness lines clash, the axes are swapped, a load sentence has no test, or one review pool is shared across two listings.
UK review notes
16%Several UK texts that name a job and a fault start at 15. Useful but thin notes start lower. A fault that changes the buy is deducted, and the floor is 0. No review text scores 0. Text from outside the UK is not British opinion.
You are choosing a tapered packer for a measured gap, not a flat installation packer and not a new fence post. The twelve amazon.co.uk files read on 21 October 2026 run from about £4.19 to about £14.99. Short black wedges cover a few millimetres under furniture. One clear four-piece set is stated at 10 mm. One pack is the fence shape, 82 × 20 × 15 mm, with no reviews. One red set is the long glazing wedge, and one 8 inch shim is the dearest file, also with no star line.
Plastic wedges are tapered pieces that fill a small gap. Household packs are short, for a wobble of a few millimetres under a table, a wardrobe or a chair. Mixed packs add a second size, in this kind of listing about 60 × 26 × 6 mm and 80 × 30 × 8 mm. A fence wedge is thicker and narrower, for the slot between a sound panel and the post. A glazing wedge is long, about 175 mm in the files read for this category.
UK reviews call a 6–10 mm wedge tiny, or wafer thin, even when the printed size is accurate. One review of the top pick expected a much thicker piece than the photograph. Measure the gap, then read the size lines.
A bullet that says 30 tons has no test in the file. The two SUMNACON packs print 4.7 from 69 and the same UK texts. Count that pool once. Neither figure is a safe working load or a second British sample.
A loose bolt, rotten fence timber, a post that rocks, glass on a door wedge, or a fire door is the wrong job. Level a washing machine on its feet first. A replacement window, misted glass or a loose soil joint needs a professional.
Start with the gap in millimetres. A 6–10 mm wedge looks tiny in UK reviews even when the printed size is accurate, so the photograph is a poor guide. Furniture wedges in this category are short, about 48–80 mm long. Mixed packs add a second size, about 60 × 26 × 6 mm and 80 × 30 × 8 mm. The fence shape here is 82 × 20 × 15 mm. The glazing wedge is about 175 mm long. The long snap piece is an 8 inch composite shim. Those are different jobs.
Read the piece count against the number of items. A title can say 20 while the item line says 40. Two files of one stated size set the unit count to 1.0 gram, and the item type on those files says Chaises Longues. Grip, stack and snap stay claims unless a UK review repeats them. Only one file in this set states pre-scored snap lines, and it has no reviews. Do not add the two star lines that both print 4.7 from 69 and the same UK texts. Count that pool once.
Three typical situations, each with a recommendation from this comparison.
You have a sound table, wardrobe or chair and a gap of a few millimetres. The top pick is the 10 black wedges stated at 30 × 50 × 6 mm, about £4.59, with 4.4 from 56 reviews. One UK review expected a thicker piece than the photograph. Stack only if you check the height again. Skip it for a fence slot or for glass.
You have a sound panel rattling in a slot and you need a fence-sized wedge, not a 6 mm furniture shim. The 20-piece listing stated at 82 × 20 × 15 mm is about £6.59. It has no star line and no review text. If the post rocks, or the timber is rotten, stop. A wedge will not fix that.
You want a mixed box of short black wedges and you can accept a six-review file. Best value is the 50-piece pack at about £6.99, stated as 30 smaller and 20 larger pieces, score 75, with a UK note on composite decking. It is about 14p a stated piece. It is not a reviewed fence wedge.
The top pick is the 10 black furniture wedges stated at 30 × 50 × 6 mm, about £4.59. It scores 78, the highest in this set, with 4.4 from 56 amazon.co.uk reviews, the largest UK review file here. It is not a lab test. One UK review expected a thicker piece than the photograph. Skip it for a fence slot, for glass, or for a gap much over 6 mm unless you stack and check again. Best value is the HongNuoEn 50-piece mixed pack at about £6.99, score 75, with its own six reviews and a decking note. That is about 14p a stated piece, against about 46p on the ten-piece top pick. The SUMNACON 60-pack is about £8.99, but its 69 reviews are the same texts as the 120-pack and the unit count says 1.0 gram, so it does not take the value award.
