WZB 1 1x1 Square Tube End Cap Plastic Plugs 12 Pack, 1x1 1 Inch Square Tubing Plug 1x1 Tube End Caps Fence Post Pipe Cap Cover Tubing Insert Chair Glide Finishing Plugs, Black

Good quality. Fits 1 inch square tube perfectly.

these work great they fit very tight have a plastic hammer handy to get them all the way in.

These end plugs worked well, as advertised. They're robust enough to be hammered into tight-fitting tubing and thus far they have remained snugly in position. Very cost effective as well. A good purchase all around.

cheep & fit

I think our patio set was bought at our local Fry's grocery store about 20 years ago. Needless to say much cheaper than what I see at our beloved Costco these days. As you see from the photos, the front and back legs are different dimensions, but what made it more complicated is that the back legs are 1"x3/4" which I could not find on Amazon so I ordered these 1"x1" plugs and just trimmed them with a razor knife. I maintained the foot dimension for longer wear life and better stability. My photos show what tools I used and how it came out. New cushions and plastic feet makes the set feel like new again and saved so much over buying new furniture. If you have a similar patio set, I hope this gives you the confidence to renew not replace. It was an easy project.

Perfect fit.

These helped me waterproof some steel tubing I am using as legs to support an outdoor sign.True to spec and fit perfectly.

Bang! Love these things.
