WZB 1 12 1.5 inch Square Tube End Cap Plastic Plugs 12 Pack, 1 12 inch 1.5 inch Square Tubing Plug 1.5 x 1.5 Tube End Caps Fence Post Pipe Cap Cover Tubing Insert Chair Glide Finishing Plugs, Black

I had a slew of wasps nesting in the bottom of steel deck railing posts. These caps solved the problem and were a perfect fit. Be sure to measure first to get the right size.

This inexpensive product, an end-cap for 1.5" square metal tubing for fence-posts, fit well and instead easily.

Worked Great

Pay attention to your wall thickness. These won’t go into heavy wall tubing and stay. But if you hand thin wall tubing they’re fine.

These caps fit perfectly in the 1.5", thin metal tube I used for my project. They are a nice, finishing touch to fill the ends.

Exactly what I needed......inexpensive on top of that.

They were just what I wanted. I had to return them however, because they were the wrong size. My fault not Amazons.

Just what I needed.
