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

The plugs fit perfectly as described. Looks great. Easy installation. Took less than a minute to install. Hint_ when installing use a small block of wood, placed against the plug and tap with a rubber mallet. Keeps you from scratching the top rail. Price is reasonable.

These worked perfectly for the ends of my gorilla lift for my trailer that were left ooen and I didn't want the rain and such wreaking havoc on it. So I decided to buy these after seeing someone else capped the ends. They fit perfect!!!

I used these for the end caps on a Gorilla Lift. They were recommended and I should’ve listened to others. I ordered them the day I installed the lift system and they came quickly and fit perfectly.

Solid squares. Well made!

Fits tight, smack them in with a mallet, they won't come out.

I wanted to close the open ends of my Gorilla Lift on my trailer and these worked perfectly.

Perfect fit for Gorilla Lift open end.

Like the tight fit , my tubing was heavy wall I sliced the corners ( the part that goes inside the tube)so when you push or tap with hammer it could overlap making fit even tighter. My application was for winch support on a boat trailer a nice tight fit was needed for me
