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 snuggly, snaps into place, looks great. A++

Used these to cap off the top of my Rogue RM-4 uprights and worked perfectly! Not that it was ever a problem but if your like me and looking for solution to cap off the top of your 3 x 3 steel power rack uprights this works.

Great fit for my bars.

What I needed

Fits perfect.

Worked great to cap the ends of a diy project using 1inch square tubing.

The listing says its a pack of 10 and notes 10 pieces. I only received four.

Worked great!

Finishing touch to my welding project!

I have 1 inch square aluminum tubing with 1/16 walls. It fits perfectly.
