Round Internal Tube Plugs — Flat Head (Pad Slot) are designed to reduce noise, protect hard floors, and improve movement where round tubing meets the ground. Open tube ends scrape surfaces, vibrate during use, and create harsh contact points that wear floors over time. Standard plugs seal the tube, but they don’t provide the soft, gliding contact needed for quiet performance.
Instead of hard plastic contact, Round Internal Tube Plugs — Flat Head (Pad Slot) combine a secure internal friction fit with an integrated groove for replaceable pad inserts. This design creates smoother movement, softer floor contact, and a cleaner, more functional finish — all without glue, screws, or complicated installation.
Basic plugs scrape. Adhesive pads peel. And once they fail, noise and floor damage return.
Round Internal Tube Plugs — Flat Head (Pad Slot) deliver a long-term solution that supports replaceable pads while keeping the plug firmly locked inside the tubing.
If your furniture needs softer floor contact…
If you want smoother, quieter movement…
If you prefer a plug that supports replaceable pads —
These plugs are built to do it all.
Your furniture glides quietly. Your floors stay protected. And your tubing gains a cleaner, more functional finish.
The integrated pad slot reduces impact, friction, and scraping — ideal for tile, hardwood, vinyl, LVT, laminate, and other hard surfaces.
Pads can be inserted, replaced, or upgraded without removing the plug, extending both floor life and plug life.
Ribbed sides adapt to minor wall variations, creating a tight, rattle-free hold inside round tubing.
A molded slot securely holds cut-to-size pads without adhesives, backing plates, or fasteners.
Keeps pads seated during movement for consistent, quiet gliding on hard floors.
Replace worn pads quickly without removing the plug from the tubing.
PE construction provides toughness while absorbing minor impacts and friction during movement.
Suitable for commercial, hospitality, educational, and institutional furniture environments.
Maintains durability from –25 °C to 65 °C without cracking or hardening.
