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.

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.
Two sizes cover the most common small rectangular tubing used in sled-base chairs, lightweight dining chairs, and compact furniture frames. Both include the bonded floor-protection pad. Match the plug to your tube’s width, length, and wall thickness.
Wall: 1–2 mm. PA body with a bonded PA6 pad. Pad contact area: 9.6 × 22.8 mm. The smaller size is for compact sled-base runners and narrow rectangular chair legs. Black only.
Wall: 1–2 mm. PA body with a bonded PA6 pad, the same PA6 material used across our furniture glides and self-adhesive pads. Pad contact area: 16 × 26 mm. The standard size for residential and light-commercial sled-base chairs and rectangular-legged dining chairs. Black only.
For other rectangular sizes without a bonded pad, use standard rectangular tube plugs (10 × 30 to 60 × 120 mm) and add a rectangular self-adhesive furniture pad for floor protection. For wide profiles, use smooth-fit rectangular tube plugs. For custom pad sizes, contact Business Solutions.
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.
The PA body grips the tube. The bonded PA6 pad handles floor contact. It pairs a ribbed press-fit grip with a factory-bonded pad on the head.
The 20 × 30 mm version uses a PA6 (polyamide 6) pad, the same material used across our furniture glides and self-adhesive pads. It is low-friction, chemically inert, and shrugs off debris. The 13.8 × 27.5 mm version carries a bonded PA6 pad sized for its smaller contact area. Both move smoothly on hardwood, tile, laminate, vinyl, polished concrete, and other smooth hard floors.
The body is PA (polyamide), which is stronger and more rigid than the PE used in standard rectangular tube plugs. The ribbed walls compress on insertion and push back against the tube interior to hold the plug in place. The PA6 pad is bonded to the head, so you get a press-fit grip plus floor protection in one part.
If your rectangular legs need both tube sealing and floor protection, here is how this version compares to the alternatives.
A standard rectangular plug plus a rectangular self-adhesive pad gets you the same result in two steps. The weak point is the adhesive bond between the pad and plug head, which can shift or peel under sideways movement over time. The with-pad version has the pad bonded to the head from the start, so there is no separate adhesive layer to fail. The trade-off: the two-step route gives you more sizes and colors. Choose with-pad for the two available sizes when you want one part; choose plug-plus-pad for everything else.
Pad slot round tube plugs have a recessed channel that holds a replaceable PA6 pad insert, so you can swap the pad without pulling the plug. On the with-pad version, the pad is bonded in place; when it wears, you replace the whole plug. Choose a pad slot for round tubes where swapping the pad matters. Choose with-pad for rectangular tubes where a one-piece part is simpler.
Standard rectangular tube plugs have a flat PE head with no pad. They seal and finish the tube, but do not add dedicated floor protection. On floors where scratches are not a concern (concrete, industrial tile, outdoor surfaces), the standard plug is enough. On hardwood, laminate, vinyl, or any finished floor, the with-pad version is the better pick.
These plugs are made for floor-contact legs and sled-base runner ends on furniture that sits on smooth, finished hard floors. The bonded pad protects the floor right away, with no extra parts or steps.
Match the plug shape to your tube shape. Every shape uses the same press-fit idea.
With bonded floor protection. PA + PA6.
Anywhere 13.8 × 27.5 or 20 × 30 mm hollow rectangular legs meet a finished hard floor, and you want the floor protection built into the plug rather than added on.
Dining chairs with sled-base runners or rectangular legs on hardwood, tile, laminate, and vinyl. The 20 × 30 mm size covers the most common residential sled-base runner. One plug handles sealing, noise, appearance, and floor protection, with no separate pad to buy, size, or apply. The PA6 pad works on every smooth hard floor type: hardwood (solid and engineered), parquet, bamboo, laminate, luxury vinyl, ceramic and porcelain tile, polished natural stone, including marble and granite, sealed concrete, cork, and linoleum. For rough, hard floors like textured tile, furniture slides with ABS surfaces handle the texture better than PA6. To protect the full runner bottom, not just the end, run rectangular self-adhesive pads along its length.
Restaurant seating, hotel dining chairs, office seating, and any commercial furniture where built-in floor protection simplifies rollout and survives commercial cleaning. For furniture makers, this plug cuts assembly steps and part count: one component finishes the tube and protects the floor. Available in bulk for production runs. For commercial pricing, visit Business Solutions.
The bonded pad needs the same care as any floor-contact pad. Check it now and then for embedded grit that could dull the slide or scratch the floor; sand and gravel tracked in from outside are the main risk. A quick wipe with a damp cloth clears anything that has collected. On commercial seating in heavy daily use, inspect every 3 to 6 months. On residential furniture, once a year is plenty. The body needs nothing beyond a check that the plug still sits flush with the tube edge.
When the pad shows wear grooves or the surface has compressed noticeably, replace the whole plug. The body tends to outperform the pad surface, so replacement is driven by pad wear rather than the body. Sold in increments of 2, so keeping spares on hand for commercial settings is easy, and replacing a worn plug costs a fraction of refinishing a scratched floor. In restaurants and hospitality settings where chairs move hundreds of times a day, a spare set stored with the cleaning supplies means a worn plug gets swapped in minutes: pull the old one, press in the new one, chair back in service.

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.
