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

It took three attempts to get the correct product, as someone had put the wrong product in the bin at the amazon warehouse. I had to make three phone calls but finally got it sorted. When these came in they were exactly what I needed for a small tile top table that is made from square tubing. It sits outside so now it wont leave rust on the patio.

This item was advertised as 1.5” square . Received it but measures 2.5”. Asked for replacement which was received promptly but still 2.5” square. Must return again!

Not as described. Will slide through a 1 square tube. at best they may fit a 3/4 tube.

used for outdoor glider bench

We used them to plug the end of 1 1/2” Tubing to keep water from getting inside the tubing and causing it to rust. Worked great.

Arrived on schedule, perfect fit for intended purpose, couldnt ask for better.

I made some hand railing using square aluminum stock. I got these to go into the ends of the aluminum stock to provide a very neat finish. They fit perfect and look great.

I use these for bottoms of table legs I make out of steel tubing. These fit great, stay in, and protect the floor. Very happy with them.

Fits perfect into 1-1/2 x 1-1/2 square tubing. Just what I needed!

Perfect replacement for my old Weber grill.Grill cover was damaged because of missing caps.
