To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
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.
