Why Choose These End Caps?
Whether you're a DIYer finishing a garden bench or a contractor protecting a fleet of metal chairs in a café, these plastic plugs provide a low-cost, long-lasting solution. The ribs hold them reliably in the tube while the thick base absorbs impact and prevents metal-on-floor contact. They keep dirt and moisture out of tubing ends, which helps reduce rust and debris build-up.
Installation Tips
- Confirm tubing outer diameter is 1.5" (1.5 x 1.5) and wall thickness is between 0.039" and 0.118".
- Clean tube interior of debris and sharp edges for best fit.
- Align plug square with tube opening and push in by hand — tap lightly with a soft mallet if necessary.
- If tubing is slightly larger or thicker than spec, consider filing edges or using a slightly larger plug size.
Common Uses
These plug caps are ideal for:
- Chair & stool legs (indoor / outdoor)
- Table legs and bench feet
- Fence posts and railing ends
- Fitness equipment & bike racks
- Trailer frames and metal frames
Frequently Asked Questions (FAQ)
Q: Will these fit 1" or 2" square tubing?
A: No — these are sized specifically for 1.5" outer diameter square tubing. For 1" or 2" tubing, choose the matching plug size.

A: Yes. The plastic material is abrasion-resistant and suitable for outdoor use, though prolonged UV exposure may eventually cause fading — consider UV-resistant options if needed.
