2Inch (50mm) Square Plastic Hole Plugs Insert (20 Pack), Heavy Duty Black Hardware Plugs and Unistrut End Caps for Square Tubing, Glide Insert for Pipe Post, Chairs and Furniture by Prescott Plastics

Plugs fit perfect for the situation I needed them for! Great tough product!

I recently purchased these for my absolutely favorite CB2 bar stools. They arrived very quickly and were a perfect fit. I did find that removing the old ones on such a small piece was quite a challenge. I wound up just drilling out the old ones carefully to avoid scratching the lovely chrome legs. These popped in easily and provide a great cushion leaving me a nice set of spares when the next set wears down.

I make Stained Glass house numbers with aluminum enclosures. This products worked well to cap my 1 tube hangers for the stained glass. Easy to install.

Purchased these for the end of a kayak trailer I built to keep out wasps etc. With a little tap from a hammer then fit very snug. They will never fall out I can guarantee that. Great price too.

As advertised. Once installed to test them on two chairs, I ordered more for the remaining two chairs and to have a few spares available for normal wear and tear over time. They fit the square leg bottoms of our counter stools perfectly!

Works as expected

They seem nice. I’ve built a few things around the house out of 1” square tubing, and these look like they’ll work nicely. A good buy

Good value. Fit perfectly!

These are thicker and have fins on all four sides to grip the inside of the tubing. They have a look of quality and durability. The hardware store plugs I purchased didnt make it through the first road trip. They are now litter somewhere on the highway. I put these in my gorilla lifts on my trailer.

had to return; wrong size
