4 Pack 1.5 Inch Square Tube End Cap Plastic Plugs, 1.5x1.5 Square Tubing Plug, Tube End CapsTubing Post End Cap Suitable for Square Tube Square Plastic Plug, Tubing Post End Cap Square Tubing

Worked perfect for capping off 2in square tube. Made project have a clean finished look. Saved me the trouble of having to weld on end caps.

These fit perfectly in the ends of my railing.

This product fit perfectly left no gaps I would buy this product again. I used on for my sliding gate on the square metal ends to keep the rain out and from getting to my locking mechanism and rusting it out. Once again great product.

Worked as needed

I was impressed by how stiff this plastic was. In fact, when I took them out of the package I worried at first that they would be a bear to insert. The retention fins were thin enough where that turned out not to be a problem and they pushed in without excessive force. There is a decent amount of plastic that abuts the tubing end-wall as well. My application was more aesthetic, but i wouldnt be too afraid to put some axial load through them- unlike some of the soft and squishy materials endcaps are often made from.

I had a single open tube on my fence that needed one of these plugs. I had a hard time finding them locally so had to purchase this 12 pack. The price was right and it saved me the headache and cost of driving around looking for them. It fit well, looks just like the existing caps on other posts and was priced right. What more could you want?

Used to replace a broken cap on my weber ssp. Fits perfect!

Trying to find replacements for 23 year old fence post cap plugs wasnt easy because most places only carry 2 square size or they charge up to $7 just for 1 plug. Amazon to the rescue. Perfect fit. Now, all I have to do is paint it to match the fence color.

Used to keep metal legs on Traeger Scout from rusting and scratching up the table. Just a tad too big, but was able to force them in with a hammer. Looks fine though.

Fit perfect
