Although my truck bed cover came with 6 clamps, I felt like 4 clamps down each side would hold the railings better. The cover manufacturer doesn't sell extra clamps, so I thought I would give these a try. They work great. Easy to install and work just as good as the original clamps I received. They hold strong. I would definitely recommend these clamps.

Bought these for putting a topper onto our ram pickup. Very user friendly and easy to use. Great price and got the job done easily.

Very easy to install sturdy metal.
