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

Great Value and easy to put on

Perfect for the square ends !!

Garbage

Perfect for boat dock.

I used these to plug the ends of 2x2 square spacers to raise an automobile seat. Makes the job look professional

Bottom as Christmas gifts for my kids

These caps fit the tubes perfectly that contain the Gorilla Lift springs and keep the elements out while driving in any kind of weather

Came in a package of four and I only needed two but having two extra may not be a bad idea. zEven though they fit perfectly into my new Gorilla-Lift 2-Sided Tailgate Lift Assist. Fast Delivery Highly Recommend Seller 5 ★★★★★s

Worked perfectly with the Gorilla Lift.

Turned out I ordered the wrong size. Not sure why it cannot be returned?
