DK –
Fit perfect and worked perfect. Great value, very happy. Put them on a 2017 Frontier and everything is great.
David LaMarche –
They work well! seems to hold my cap on just fine. For some reason they never sell this locally, so amazon it is!
Driftwood –
I bought a cap with only 3 clamps, Amazon showed me the way to buying one, not four …perfect match, tough as nails…thank you Amazon!
Charlie & Betty –
These were purchased as replacements for ones where the bolt had seized and snapped off when I tried to remove them
Shawnc_4 –
It does the job, bought as a replacement for another clamp that was stripped out. Do not over tighten, it will strip the treads in the clamp.
Erik S. Anderson –
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.
D. Stone –
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 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.
