A round glide on a square leg leaves the corners bare to scratch the floor. These cover the leg corner to corner in PA6 fiber, gliding silent and scuff-free, with a zinc-plated rivet that taps into solid wood. No pre-drilling, no adhesive.

A round glide on a square leg leaves all four corners exposed. Corners are the sharpest, highest-pressure contact points on any furniture leg. Every push and pull grinds bare wood into your floor finish at exactly those unprotected points.
Square nail-on furniture glides solve this at the geometry level. The square PA6 needle-punched fiber surface matches the leg cross-section corner to corner, so every edge is covered, and no wood ever contacts the floor—silent, scratch-free movement on hardwood, tile, laminate, vinyl, and stone.
Felt compresses flat, traps debris, and peels off within a month. PA6 fiber holds its structure. These are the square chair glides for hardwood floors that Parsons chairs, straight-leg tables, and mid-century sideboards need.
A zinc-plated tubular rivet drives into solid wood with a rubber mallet. An anti-rotation notch molded into the rivet locks the glide in alignment with all four corners.: nopre-drilling, no adhesive, no curing time.
Square nail-on furniture glides are available in sizes from 23 mm to 75 mm. Nail-on chair leg protectors for square wooden legs on every smooth, hard floor. For solid wood legs only.
Square legs look simple, but the base dimension isn’t always what you expect. Tapered designs are wider at the top and narrower at the bottom.
The only measurement that matters is the flat face at the very bottom of the leg, where the glide will sit. Measuring takes 30 seconds and gets you the right square furniture floor protectors for every leg on the piece.
Lay the piece on its side or turn it upside down. You need full access to the flat bottom face of each leg where the square nail-on furniture glide will sit.
Use a ruler across one edge of the flat base, in millimeters. Both sides should be equal on a true square leg. If the sides are noticeably different lengths, the leg is rectangular. Use rectangular nail-on furniture glides instead.
Select the square nail-on furniture glide whose range includes your measurement. If your measurement lands on a boundary, choose the smaller size so the glide stays inside the leg footprint.
Installation takes under a minute per leg. No pre-drilling required on any hardwood, MDF, or softwood species.
Square nail-on furniture glides seat flush with a rubber mallet and lock in position through the anti-rotation notch.
PA6 is chemically inert and leaves no marks, scuffs, or residue on any sealed floor finish. The National Wood Flooring Association (NWFA) recommends furniture protectors on every leg as a primary hardwood maintenance step.
Square nail-on furniture glides meet that standard across every smooth, hard floor type. Corner-to-corner hardwood floor protectors that cover every square millimeter.
Square nail-on furniture glides are built on the same ABS platform and rivet construction used across the nail-on line. The only difference is the contact surface, which determines whether furniture moves freely or holds position.
Low-friction PA6 fiber for square-legged furniture that repositions regularly. Parsons chairs, dining tables, kitchen seating, and desks. These are the corner-to-corner nail-on chair glides you’re viewing now.
Controlled grip for square-legged furniture that must stay put. Media consoles, sideboards, display furniture. Anywhere sliding is a problem or a safety concern.
Both variants use the same ABS platform and ZnFe tubular rivet with an anti-rotation notch. The PA6 and NR+CR surfaces cannot be swapped in place. Removal and replacement with the correct variant is required.
The glide shape must match the leg cross-section. A mismatch leaves part of the leg base unprotected, and unprotected contact points are where floor damage happens. All three shapes use the same PA6 surface, ABS platform, and ZnFe rivet.
For circular, turned, tapered, and cylindrical legs. from Ø 23 mm to Ø 75 mm.
For equal-sided square legs. Full corner-to-corner PA6 coverage. from 23 × 23 mm to 75 × 75 mm.
For rectangular legs with unequal sides. Mid-century and Scandinavian furniture. 33 × 19 mm.
It was scratched by the pad you put there to protect it. Here is how that happens, and what we do differently.
It picks up sand and grit from the floor and holds it there. Every time the chair moves, that grit is dragged across the finish. The pad is still doing its job, and it is the thing causing the damage.
Vertical fiber, not a flat mat. It does not trap debris the way flat felt does, and it is built to take repeated movement without compressing flat.
| What happens | Cheap felt pad | Superior Glide |
|---|---|---|
| Structure | Flat, matted fiber with an open surface | PA6 needle-punched fiber |
| Grit | Absorbs it and holds it against the floor finish | Does not trap debris the way flat felt does |
| Under weight | Compresses, and stays compressed | Built to take repeated movement without compressing flat |
| Staying on | Hardware-store pressure-sensitive backing creeps under sideways load and lets go at the leg face | Nail-on with a zinc-plated tubular rivet. It taps into solid wood and grips a wider area than a nail or a screw |
| Fit | An assortment pack, and you hope one size lands | Sized to your leg. Measure the base, order the size that sits flush or just inside it |
| Floor match | Sold as suitable for every floor | Matched to your floor. PA6 fiber for smooth hard floors, ABS for carpet and rough floors |
These glides are for smooth hard floors: hardwood, engineered wood, laminate, luxury vinyl, linoleum, cork and polished tile. For carpet, textured tile, or any floor with deep grout lines, you want furniture slides instead.
| Size (W × L) | Fits legs measuring |
|---|---|
| 23 × 23 mm (0.91″ × 0.91″) | 23 to 27 mm (0.91″ to 1.06″) |
| 28 × 28 mm (1.10″ × 1.10″) | 28 to 37 mm (1.10″ to 1.46″) |
| 38 × 38 mm (1.50″ × 1.50″) | 38 to 49 mm (1.50″ to 1.93″) |
| 50 × 50 mm (1.97″ × 1.97″) | 50 to 74 mm (1.97″ to 2.91″) |
| 75 × 75 mm (2.95″ × 2.95″) | 75 to 95 mm (2.95″ to 3.74″) |
Measure the flat base of the leg and choose the size in that row. The glide sits flush with the leg base or just inside it, never wider. For legs over 95 mm (3.74″), use a self-adhesive furniture pad, which is sized to the leg rather than fitted to it.
One sheet covers round, square, and rectangular legs, for both nail-on and self-adhesive versions.

A round glide inscribed inside a square leg leaves all four corners exposed. Corners are the highest-pressure contact points on any furniture leg, and they concentrate the full weight of the piece into a small area. Every push, pull, or tilt grinds a bare corner directly into the floor finish. Square nail-on furniture glides match the leg cross-section corner to corner, so every edge is covered and no wood contacts the floor.
Flip the furniture and measure one edge of the flat base at the very bottom of the leg, in millimeters. Both sides should be equal on a true square leg. Match your measurement to the size chart: 23 mm (fits 23–27 mm), 28 mm (fits 28–37 mm), 38 mm (fits 38–49 mm), 50 mm (fits 50–74 mm), 75 mm (fits 75 mm and above). If the two sides are noticeably different, the leg is rectangular. Use rectangular nail-on furniture glides instead.
A square glide that rotates even slightly after installation exposes one or more corners to the floor. Those exposed corners are bare wood on the finish. The anti-rotation notch molded into the ZnFe rivet locks the glide in the correct orientation and prevents spinning under load. Align all four edges of the glide with the leg edges before striking. Once the rivet is seated, the notch holds that alignment as the furniture moves.
Both use the same ABS platform, the same ZnFe rivet, and the same five sizes. The difference is the floor-contact surface. Square nail-on furniture glides (Smooth Glide) use low-friction PA6 fiber for furniture that needs to move freely, like Parsons dining chairs. Square anti-slip nail-on furniture glides use NR+CR rubber for furniture that must stay put, like media consoles and display tables. Both fit the same rivet hole.
Yes. PA6 is chemically inert and non-staining on all sealed floor finishes, including LVP, LVT, and sheet vinyl. The National Wood Flooring Association (NWFA) recommends furniture protectors on every leg as a primary maintenance step. PA6 will not discolor, mark, or leave residue on any sealed smooth, hard floor. The full corner-to-corner coverage ensures no bare wood contacts the vinyl surface.
A square nail-on glide, matched to the leg size so the corners are covered. It taps into the wood with a rubber mallet and puts a PA6 face between the leg and the floor.
