Prescott Plastics 1.75" Inch Round Plastic Plug Insert (8 Pack), End Cap for Metal Tubing, Fence, Glide Insert for Pipe Post, Chairs and Furnitures

I ordered these once before to put on the bottom of my wrought iron chair legs and they worked fine. One broke recently so I reordered. I didn’t think I was going to get it to go in this time, even though everything looked the same. Then I read the review about warming them up first so I microwaved one about a minute and I squished right in! Good as new.

to make it easier to use, warm up the plug first, then it's easier to squish the ribs into the hole in your desk.

Ease of use and install. Thanks for quick delivery

used for homemade stair railing

Worked great for plugging roll cage piece on RZR
