A round slide on a square leg leaves all four corners exposed to catch and tear carpet pile. This one covers every corner in hard ABS that skims over the pile with zero fiber engagement. The same hard face handles rough hard floors: slate, brick, and grout lines. A zinc-plated rivet with an anti-rotation notch taps into solid wood and stays aligned. For solid wood legs only.

The difference
Carpet needs a face that rides over the pile, not one that digs into it.
| What matters | Felt pad or plain plastic cap | Superior Glide |
|---|---|---|
| On the carpet | Felt locks into the pile; plastic caps dig an edge in. The chair judders instead of sliding. | A smooth, hard ABS face that rides over the pile and across grout lines. |
| How it stays on | Glued felt peels; a single nail works loose. | Tubular rivet or extra-high-bond adhesive, matched to the leg. |
| Sizing | One size covers everything, badly. | Sized to the leg base so the edge never catches. |
| When it wears | Replace and re-glue. | Refits in the same spot. 90-day warranty. |
In more detail
Square legs have four corners that dig into the carpet pile. A round slide on a square leg leaves those corners exposed: they catch, snag, and tear carpet fibers with every movement. Square nail-on furniture slides cover every corner edge to edge with a hard ABS surface that slides over carpet pile instead of digging into it. The smooth, precision-formed ABS face presents zero fiber engagement across the full square footprint, including all four high-load corners where damage is worst. Sold in the US as square furniture sliders for carpet, they let a loaded chair move with a push rather than a shove.
A zinc-plated tubular rivet drives into solid wood legs with a rubber mallet. An anti-rotation notch molded into the rivet locks the slide in alignment with the square leg and prevents it from spinning under load. No pre-drilling, no adhesive. Square nail-on furniture slides come in from 23 × 23 mm to 50 × 50 mm. Square chair slides for carpet, carpet tile, and area rugs. Corner-to-corner ABS protection on solid wood furniture.
The most common mistake when ordering nail-on slides for square legs is guessing the size. A 23 mm slide on a 38 mm leg wobbles and leaves all four corners digging directly into the carpet pile, defeating the entire purpose. Measure both sides of the leg base before ordering.
Step 1. Flip or tilt the furniture
Lay the piece on its side or turn it upside down. You need clear access to the base of each leg where the slide will sit.
Step 2. Measure both sides
Use a ruler or calipers across both sides of the leg base independently. If the two measurements differ by more than 3 mm, the leg is rectangular: use rectangular nail-on furniture slides instead.
Step 3. Match to the size chart
Select the slide whose range includes your measurement. A 34 × 34 mm leg falls within the 28 × 28 mm slide option (fits legs 28-37 mm per side). If you're right on a boundary, go with the smaller size.
Tapered square legs: measure at the very bottom, not mid-leg. The bottom face is the only measurement that matters. If the leg tapers from a larger cross-section, the base measurement determines the slide size.
Installation takes under a minute per leg. No pre-drilling required on any hardwood, MDF, or softwood species. Corner alignment during installation is critical. The anti-rotation notch locks after the rivet is seated, and a misaligned slide exposes corners to catch on carpet fibers.
What you need
Installation steps
Why corner alignment matters: a round slide can spin freely without consequence; every orientation is identical. A square nail-on furniture slide that rotates even a few degrees exposes corners and creates an overhang that catches carpet fibers. The anti-rotation notch prevents this after installation, but initial alignment must be correct before the rivet is driven.Removal and replacement: Pry gently from one edge with a flat-head screwdriver. The tubular rivet separates cleanly: fibers spring back when removed. A new slide seats tightly in the same hole without loss of grip. You can also swap to square nail-on furniture glides in the same hole if the furniture moves to a smooth, hard floor.
Carpet fiber fights every furniture movement. But square legs make the problem worse. Round legs at least present a continuous curve that can part carpet fibers somewhat evenly. Square legs present four sharp corners that dig into the pile like anchors, tearing fibers and creating the maximum possible resistance to movement.
How square corners damage carpet
Each corner of an unprotected square leg concentrates the furniture's weight into a sharp point. When the furniture is pushed or pulled, those four points drag through the carpet pile: tearing fibers, crushing pile, and creating deep tracks. The Carpet and Rug Institute (CRI) recommends furniture protectors on all legs to prevent the premature pile damage that concentrated corner pressure causes. Square nail-on furniture slides eliminate all four of those contact points.
How ABS solves the square-leg problem
The ABS surface replaces four sharp corner contact points with a single smooth, flat surface that skims over carpet pile instead of digging through it. The friction between smooth ABS and carpet is dramatically lower than between raw wood corners and carpet. ABS also distributes weight evenly across all four corners instead of concentrating it at sharp points, reducing carpet pile compression and protecting against deep indentations. Unlike generic protectors that compress and fail, the rigid ABS surface holds its shape under sustained load.

These slides work on any surface where furniture legs sink into or engage the material. The hard ABS face skims over the surface instead of engaging it. Also recommended for square legs on rough or heavily textured hard floors where PA6 glides catch or wear prematurely.

Square nail-on furniture slides and square nail-on furniture glides use the same platform and rivet. The right choice depends entirely on the floor type, not the furniture.
ABS: These slides
For carpet, carpet tile, area rugs, and rough-textured hard floors. The hard ABS surface skims over the carpet pile instead of engaging it. Eliminates corner snagging and reduces the force needed to move furniture. This is the product you are viewing.
You are viewing this product.PA6: Square Nail-On Furniture Glides
For hardwood, tile, laminate, vinyl, stone, and all smooth, hard floors. The soft PA6 needle-punched surface absorbs micro-texture and moves silently without scratching. Glides protect the floor from the furniture. Slides protect the carpet from the furniture.
Both variants use the same ABS platform and ZnFe tubular rivet with an anti-rotation notch. Only the floor-contact surface differs. ABS for carpet, carpet tile, and rugs. PA6 for smooth, hard floors.
The slide shape must match the leg cross-section. A round slide on a square leg leaves all four corners exposed to catch and snag on carpet fibers, creating the exact problem the slide is supposed to eliminate.
Round
For circular, turned, tapered, and cylindrical legs. from Ø 23 mm to Ø 50 mm.
Square ← You are here.
For equal-sided square legs. These slides cover every corner with ABS. from 23 × 23 mm to 50 × 50 mm.
Rectangular
For rectangular legs: Mid-century modern and Scandinavian furniture. Full-length ABS coverage. 33 × 19 mm.
Measure the widest point of the flat base of the leg, then choose the size on that row. The glide should sit flush with the leg or just inside it, never wider.

| 50 × 50 mm (1.97″ × 1.97″) | 50 to 65 mm (1.97″ to 2.56″) |
Measure the flat base of the leg and choose the size in that row. The slide sits flush with the leg base or just inside it, never wider. On carpet a slide has to float on the pile, so coverage matters: a slide much smaller than the leg sinks in. 50 mm is the largest slide made, so legs over 65 mm (2.56″) are not covered by this line.
One sheet covers round, square, and rectangular legs, for both nail-on and self-adhesive versions.

A round slide inscribed inside a square leg leaves all four corners completely unprotected. Those corners are the sharpest contact points on the leg and the first place that catches and tears carpet fibers during movement. Square nail-on furniture slides cover the full footprint, corner to corner. No exposed edges, no snagging.
Critical. A square slide that rotates even a few degrees exposes corners to the carpet. The anti-rotation notch molded into the rivet prevents rotation after installation, but the initial strike must seat the slide in alignment. Line up all four edges with the leg before striking the rivet.
Yes. The tubular rivet parts wood fibers rather than boring them out. When you remove a slide, the fibers spring back. A fresh rivet seats tightly in the same hole. Swap to square nail-on furniture glides for hardwood, tile, or laminate, or back to slides when the furniture returns to carpet.
Measure at the very bottom of the leg, not mid-height. Tapered square legs are wider at the top and narrower at the base. A leg that measures 40 mm at mid-height but 32 mm at the base needs the 28 × 28 mm slide, not the 38 × 38 mm. Always size to the base where the slide actually sits.
Yes, ABS can scratch smooth, hard floors. If your furniture moves between carpet and smooth, hard floors, swap to square nail-on furniture glides with a PA6 surface when the furniture is on smooth, hard flooring. Both fit the same rivet hole. No filler needed.
