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

Perfect fit for 3/4 chair leg tube.

great product for my project.

Nice looking product, excellent quality !!

Title says it all, they do what they are designed to do.

My butterfly machine by Wate-man Fitness equipment, base rusted away and a local welder fabricated the identical base. These black plastic plugs snapped right in finishing the new base.

Great product. Fit like I needed them to

Fits great on Bimini top railings. And can cut for custom fit....

These plugs work just as they are advertised to work. Easy to use and we really like them.

as expected

They were a good replacement for some existing caps that I had modified to hold lights. I removed the lights and so wanted new caps. They installed firmly with a few taps of a rubber mallet, but a little off center due to the tight initial fit. That said, I have no concern they will stay in place.
