Great

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.

They went on very easy and made the product look like it had be made by a pro. That not me. I would buy them again it I needed them.

These plug holes of the appropriate size.

I used them for end caps on the aluminum tubing that my kayak trailer has. Unfortunately the plastic collapsed when installing them.

Size as advertised fits to perfection. Looks very good.

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.

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

Worked perfectly for my hammock frame on my deck.

The product was as described and seems to fit my needs.
