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

Exacctly what I wanted arrived. Fast, efficient.

Worked great to cap some aluminum tubes used for a jig. Gave the jig a much more professional appearance.

I liked the table legs stopper it worked very well for my project.

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.

Fits perfect for my work bench! Nice price!

Sad someone cannot count to 10. I recieved 9 paid for 10. Other than that they work perfect

So easy to use popped right in my chairs, and they look good as new.

They fit but are loose.

Used on aluminum patio chairs. A little snip for proper sizing and off we go.

Fits very tightly and is perfectly flush with outside of metal tubing. Looks very professional.
