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

I had been looking for end caps for my railing which had blown away during the hurricane. They fit perfectly.

Bought these to put on the ends of my Zero grind rail and they fit perfectly. Very secure fit, used hammer to insert. Very pleased with the result.

You will need a mallet to install or something soft to tap it into the tubing. I tried by hand but needed that extra help. Don’t get me wrong I’m happy it fits that snug. It helps with theft or just being to loose. This is a quality product. I recommend it.

Theyre plastic plug caps. They work like they should. Nothing fancy.

didnt fit right

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.

fir and worked perfectly

Ive purchased and used these caps in 1.5 square steel and 1 aluminum tubing. Good tight fit in each! MUCH cheaper here than in big box stores (if you can even find them)

Have used similar products, but this brand is not that good. Most of the time the product will break or slip with a bad fit. Used rubber mallet and once its slightly off side the unit is just trash. Almost 50% wastage. And overall this is extremely pricy to start with.

The plug is a nice strong fit. Good material for it. I used a hammer
