Finishes off the gate nicely and easy to install.

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

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.

Just over prices for some cheap plastic. But worked so here are 4 stars

Great replacement part for my rv

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.

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.

Husband is very pleased with this product.He used them to seal holes in the tubing on his lumber rack to keep wasps out.

These plug holes of the appropriate size.
