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

Fits perfectly. Lost one of the end caps for my table saw. These look different but they work and I’m the only one who knows the difference.

A little pricey for plastic plugs, but they worked.

As a chair foot this is too thin to hold up on a hard surface. It might be OK on carpet, but thats not my application so I returned this item. The item fits the square tubing well and does not move once in place.

Exactly how it was described worked wonderfully

Early delivery - cap fit perfectly!

These were a perfect fit...exactly as described

I misplaced the similar cap/plug from a Thule 2-bike carrier (covered the opening for connecting a 2-bike extension) and wanted a replacement to keep the interior of the steel tube clean and dry. I only needed one cap/plug but the smallest package available was four, so Ill have the other three banging around in my spare parts box, but the cap/plug fit snugly and looks just like the OE piece I lost. I havent tried to remove the cap/plug to use the extension yet, but I can tell it will take some effort. However, better that than have it so loose it falls out and gets lost!

Work perfectly

Needed to replace some feet on a shelf. These worked fine, and I now have a lifetime supply. Gave a few to a friend to use, and they work great for him as well.

Excellent product
