A hollow rectangular leg needs its open end capped and the floor under it protected. This does both in one press-fit piece: the ribbed PA body grips inside the tube while a bonded PA6 pad shields smooth, hard floors from scratches. No separate stick-on pad to line up. Two sizes: 13.8 × 27.5 mm and 20 × 30 mm. Black.
We make this size in production runs, so there is none on the shelf today. Tell us how many you would want and you go on the list for it. When enough people ask for a size, we run it, and the people who asked hear about it first.
We stock a limited range of tube sizes and wall thicknesses. Tell us the size you need and we will confirm availability and pricing by email.

A standard rectangular tube plug seals the tube end and handles noise and appearance. What it does not do is protect the floor. On hardwood, laminate, or any surface where marks show, the usual fix is to stick a separate pad on the plug after installation. This version skips that second step: the floor-protection pad is bonded straight to the plug head, so one press-fit part seals the tube and protects the floor at the same time.
PA (polyamide) body with flexible internal ribs and a bonded PA6 pad on the head. Built for hollow rectangular furniture legs that sit on floors where every scratch shows. Two sizes: 13.8 × 27.5 mm (PA6 pad area 9.6 × 22.8 mm) and 20 × 30 mm (PA6 pad area 16 × 26 mm). Wall thickness 1–2 mm. Black. Sold in increments of 2.
Three measurements, the same as any rectangular tube plug: width (short side), length (long side), and wall thickness. Your tube needs to match one of the two sizes exactly. The 13.8 mm width is non-standard, so measure carefully: 13.8 mm is not 14 mm.
Use calipers across each side of the rectangular tube, outside edge to outside edge. Record the short side (width) and the long side (length). The two sizes are 13.8 × 27.5 and 20 × 30 mm.
Use calipers at the tube end. Both sizes need a 1–2 mm wall for the ribs to grip properly.
Width, length, and wall thickness all have to match. If your tube is 20 × 30 mm but the walls are 2.5 mm, the pad version will not seat. Use a standard 20 × 30 rectangular plug in the right wall range and add a separate self-adhesive pad instead.
Press-fit is the same as a standard rectangular tube plug. The bonded pad does not change anything. Line up width to width and length to length, then press in by hand. The ribbed PA body grips the tube interior. The pad faces the floor.
Everything a standard tube plug does, plus built-in scratch protection for smooth hard floors, with no separate pad to apply. The National Wood Flooring Association (NWFA) recommends protective pads under furniture legs, and this plug puts one there in a single press-fit part.
The main reason to choose this version. The pad is bonded to the plug head, so there is no separate adhesive layer between the pad and plug to peel or shift under sideways movement. On sled-base chairs where the runner end meets the floor, the pad protects from the first day. Nothing extra to source, size, or stick on. Compared with leaving bare plastic or metal on a smooth, hard floor, the pad takes the contact instead of the finish.
The same sealed end as every other plug in the range. The PA body fills the tube opening and keeps moisture, debris, and insects out. Sled-base runners sit right at floor level, so their ends are especially exposed to mop water and tracked-in grit. This plug seals the end and protects the floor at once.
The pad is quieter than bare PA on a smooth, hard floor. It softens contact noise and takes out the scrape that metal and hard plastic make. In restaurants, cafeterias, offices, and schools where rectangular-legged chairs move all day, that quieter contact comes built in, with no separate part to add.
For furniture makers, this plug removes a production step. No separate pads to stock, no adhesive station, no check on pad alignment. A single component goes on at the end of the line and delivers both tube sealing and floor protection, which cuts assembly time and part count. For volume pricing, visit Business Solutions.
Match the plug shape to your tube shape. Every shape uses the same press-fit idea.
With bonded floor protection. PA + PA6.
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.
The face that meets the floor is 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 | The pad face comes fitted to the body, and the body grips the leg by press fit or thread. There is no tape to fail |
| 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 |
The PA6 pad face makes this a smooth hard floor part: hardwood, engineered wood, laminate, luxury vinyl, linoleum, cork and polished tile. For carpet or rough floors, ask us for the version without a pad.

Standard rectangular tube plugs have a flat PE head. You apply a separate self-adhesive pad on top. Rectangular tube plugs with pad have the floor protection bonded to the PA head during manufacturing. The pad cannot shift, peel, or fall off. One product, one step.
No. The pad is permanently integrated during manufacturing. When the pad wears, replace the entire plug. The press-fit design makes removal and reinstallation straightforward. This differs from pad slot round tube plugs, which have a replaceable insert.
The body is PA (polyamide, also known as nylon). PA has higher tensile strength and rigidity than PE (polyethylene), which matters for two reasons. First, the retention ribs must grip the inside walls of the tube firmly enough to resist pull-out under daily furniture movement. Second, the pad slot must hold a PA6 pad securely without flexing or deforming under sustained chair weight. PE would flex too much under load to maintain pad retention.
The pad slot adds material thickness to the plug head, which changes the insertion geometry. The two sizes available (13.8 × 27.5 mm and 20 × 30 mm) cover the most common sled base runner and lightweight chair tubing where PA6 floor protection is needed. Standard rectangular tube plugs cover more sizes because the simpler head design works across a wider dimensional range.
Yes. The 20 × 30 mm version uses the same PA6 needle-punched fiber found in all our furniture pads and glides. The 13.8 × 27.5 mm version has an integrated pad optimized for its smaller contact area. Both provide low-friction, scratch-free movement on hardwood, tile, laminate, vinyl, and other smooth, hard floors.
