Standard rectangular tube plugs seal the tube and provide basic PA or PE floor contact. That handles sealing, noise, and appearance. But it does not handle scratch protection on hardwood, laminate, or any floor where marks show. The usual solution is to add a separate self-adhesive pad after installing the plug. Rectangular tube plugs with pad skip that second step by integrating the floor-protection pad directly into the plug head during manufacturing. One product. One installation. Tube sealing and floor protection in a single press-fit unit.
PA (polyamide) body with flexible internal ribs. Integrated pad bonded to the head. Rectangular tube plugs with pad are tube plugs with integrated floor protection for hollow rectangular furniture legs where every scratch on the floor shows. 2 sizes: 13.8 × 27.5 mm (pad area 9.6 × 22.8 mm) and 20 × 30 mm (PA6 pad area 16 × 26 mm). Wall thickness 1 to 2 mm. Black. Sold in multiples of 4.
Rectangular tube plugs with pad are available in two sizes that cover the most common small rectangular tubing used in sled base chairs, lightweight dining chairs, and compact furniture frames. Both sizes include the integrated floor-protection pad. The right plug matches your tube’s width, length, and wall thickness.
Wall: 1 to 2 mm. PA body with integrated pad. Pad contact area: 9.6 × 22.8 mm. Height: 13 mm (body), 8 mm (head). Weight: 5.1 g. The smaller size for compact sled base runners and narrow rectangular chair legs. Black only.
Wall: 1 to 2 mm. PA body with PA6 needle-punched pad. Pad contact area: 16 × 26 mm. The same PA6 fiber used in all our furniture glides and self-adhesive pads. Standard size for residential and light commercial sled base chairs and rectangular-legged dining chairs. Black only.
For other rectangular sizes without an integrated pad, use standard rectangular tube plugs (32 sizes, 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.
Same three measurements as all rectangular tube plugs: width (short side), length (long side), and wall thickness. Your tube must match one of the two available sizes exactly. The 13.8 mm width is a non-standard dimension that corresponds to specific European furniture tubing specifications.
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 available sizes are 13.8 × 27.5 and 20 × 30 mm. Precision matters: 13.8 mm is not 14 mm.
Use calipers at the tube end. Both sizes require 1 to 2 mm wall thickness for the ribs to grip properly.
Width, length, and wall thickness must all match. If your tube is 20 × 30 mm but with 2.5 mm walls, the pad version will not seat properly. Use a standard 20 × 30 rectangular plug in the appropriate wall range and add a separate self-adhesive pad instead.
Same press-fit installation as standard rectangular tube plugs. The integrated pad does not change the process. Align width to width and length to length, then press in by hand. The PA body with ribs grips the tube interior. The pad faces the floor.
Every benefit of a standard tube plug, plus integrated hard-floor scratch protection that requires no separate pad application. The National Wood Flooring Association (NWFA) recommends protective pads on all furniture legs, and rectangular tube plugs with pad meet that recommendation in a single press-fit product.
The primary advantage. The pad is bonded to the plug head during manufacturing. It cannot shift, peel, or fall off. On sled base chairs where the runner end contacts the floor, the integrated pad provides scratch-free contact from the moment of installation. No adhesive to fail. No separate pad to source, size, and apply. Rectangular tube plugs with pad are floor protection tube plugs rectangular profiles need in environments where floor damage is visible and costly. Unlike leaving metal or bare plastic on hard floors, the pad prevents damage at the source.
Same sealed end as every other plug in the range. The PA body fills the tube opening and keeps moisture, debris, and insects out. On sled base runners that sit at floor level, the tube ends are especially vulnerable to mopping water and tracked-in debris. Rectangular tube plugs with pad seal the end and protect the floor simultaneously.
The pad surface is quieter than bare PA or PE on hard floors. It absorbs contact noise and eliminates the scraping that metal and hard plastic create. In restaurants, cafeterias, offices, and schools where rectangular-legged chairs move constantly, the integrated pad reduces noise without a separate product. Rectangular plugs with PA6 pad that silence and protect at the same time.
For furniture manufacturers, rectangular tube plugs with pad eliminate a production step. No need to stock separate pads, no adhesive application station, no quality check on pad alignment. One component installs at the end of the assembly line and delivers tube sealing plus floor protection. Rectangular tube plugs built-in pad that reduce assembly time and part count.

Two materials in one product. The PA body handles tube grip. The integrated pad handles floor contact. Rectangular tube plugs with pad combine the proven ribbed PA grip mechanism with factory-bonded floor protection.
The 20 × 30 mm version uses PA6 needle-punched polyamide 6 fiber, the same material used in all our furniture glides and self-adhesive pads. Low friction, chemically inert, deflects debris. The 13.8 × 27.5 mm version has an integrated pad optimized for its smaller contact area. Both provide scratch-free movement on hardwood, tile, laminate, vinyl, polished concrete, and other smooth hard floors.
PA provides higher tensile strength and rigidity than PE, which supports the integrated pad more effectively. The ribbed walls compress during insertion and grip the tube interior. PA bonds more reliably with the pad material during manufacturing than PE would, which is why the with-pad variants use PA instead of the PE used in standard rectangular tube plugs.
If your rectangular furniture legs need both tube sealing and floor protection, here is how rectangular tube plugs with pad compare to the alternatives.
A standard rectangular plug plus a rectangular self-adhesive pad achieves the same result in two steps. The adhesive bond between pad and plug head is the weak point: under lateral movement, the pad can peel or shift over time. Rectangular tube plugs with pad have the pad factory-bonded to the head, which is more secure. However, the two-step approach gives you more size and color options. Choose with-pad for the two available sizes when you want a one-step solution. Choose standard plug plus pad for all other sizes.
Pad slot round tube plugs have a recessed channel that holds a replaceable PA6 pad insert. The pad can be swapped without removing the plug. Rectangular tube plugs with pad have the pad permanently bonded. When the pad wears, replace the entire plug. Choose pad slot for round tubes where pad replacement is important. Choose with-pad for rectangular tubes where a one-piece, no-maintenance solution is preferred.
Standard rectangular tube plugs have a flat PE head with no pad. They seal and finish the tube but do not provide dedicated floor protection. On floors where scratches are not a concern (concrete, industrial tile, outdoor surfaces), the standard plug is sufficient. On hardwood, laminate, vinyl, or any finished floor, rectangular tube plugs with pad are the better choice.
Rectangular tube plugs with pad are designed for floor-contact legs and sled base runner ends on furniture that sits on finished hard floors. The integrated pad provides immediate floor protection with no additional products or steps.
Match the plug shape to your tube shape. Every shape uses the same press-fit concept.
2 sizes with integrated floor protection. PA + PA6.
Anywhere 13.8 × 27.5 or 20 × 30 mm hollow rectangular furniture legs contact finished hard floors and floor protection needs to be built into the plug rather than added separately.
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. No separate pad to buy, size, or apply. The PA6 pad on the 20 × 30 mm version works on every smooth hard floor type: hardwood (solid and engineered), parquet, bamboo, laminate, luxury vinyl, ceramic and porcelain tile, natural stone including marble and granite (polished), sealed concrete, cork, and linoleum. For rough hard floors like textured tile, furniture slides with ABS surfaces handle the texture better than PA6. For the sled base runner bottom (not just the end), apply rectangular self-adhesive pads along the full runner length.
Restaurant seating, hotel dining chairs, office seating, and any commercial furniture where integrated floor protection simplifies deployment and survives commercial cleaning. For furniture manufacturers, rectangular tube plugs with pad reduce assembly steps and part count. One component finishes the tube and protects the floor. Available in bulk for manufacturing runs. For commercial pricing, visit Business Solutions.
The integrated pad requires the same care as any floor-contact pad surface. Check periodically for embedded grit or debris that could reduce sliding performance or scratch the floor. Sand and gravel tracked in from outside are the primary risk. A quick wipe with a damp cloth removes anything that has collected on the pad surface. On commercial seating that sees heavy daily use, inspect every 3 to 6 months. On residential furniture, an annual check is enough. The PA body does not require any maintenance beyond confirming the plug remains seated flush with the tube edge.
When the pad shows visible wear grooves or the fiber has compressed noticeably, replace the entire plug. The PA body stays intact longer than the pad surface, so replacement is driven by pad wear, not body failure. Rectangular tube plugs with pad are sold in multiples of 4, so keeping spares on hand for commercial environments is practical. The cost of replacing a worn plug is a fraction of refinishing a scratched floor. In restaurants and hospitality environments where furniture moves hundreds of times daily, having a replacement set stored with the maintenance supplies means a worn plug can be swapped in minutes during routine cleaning. The PA body does not crack or deform during removal, so the swap is clean: pull the old plug, push in the new one, and the chair is 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 x 27.5 mm and 20 x 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.
