2 Black Plastic Plugs for Square Tubing by Caplugs Package of 4

Work fine

Works on the gorilla trailer gate assist as an end cap

Worked great.

Easy to install. Worked great on my heavy wall 2” x2” tubing.

Perfect fit.

I ordered 2 square plastic plugs to cover the openings in the 2 tubular steel crossarms of my clothesline post. They were easy to install and fit perfectly to cover the openings. Now the clothesline pole looks like it was made by professionals.

Good end caps

Fit well easy to install

They do what they are meant to do.

works as expected
