I have used a few different styles so far. Prefer these clamps. Just bought a 2nd set. The long flats allow a much stronger hold and secure hold than shorter flats. Worth the money. Simple to use.

Great deal for me, I only needed one to replace a clamp that had broken and did not need to buy four, which was all what others were offering. So I saved money buying two and have one extra, not three for more money which worked for me. The clamps are similar to my old ones and attached my pick-up cap to my pick-up well. I suggest these if you just need a few, or four!

I had 4 topper clamps for my topper on my F-150 6.5 ft box. (2 on each side) I decided I wanted 3 on each side, so I bought these 2 off of Amazon. It's the 2 middle clamps in each picture. Happy with my purchase.
