CODUPAX Stainless Steel Truck Tonneau Cover Replacement and Accessories Part Kit for Hard Truck Bed Cover Include T-Bolt, Rear Clamp(2 Pack)

These worked perfectly for locking my tountu cover. Great purchase.

Good replacement for Mostplus bed cover.

Well made but not universal...the top part that goes into the rail is rectangle & too big mine is a smaller square so no way to make this fit & I've yet to find a match for mine

Just what I needed works fine

It’s very cheap the screw bend the lock open while you’re driving

This did not work for my tarp however I was preparing to send them back and I found that all I needed was the little silver cylinder so I took it out and added it to my own clamp and it worked so in the long run it was worth the price versus buying a new tarp But don’t expect it to fit your truck they require a different kind of track than what my tarp has

The metal threads on the screws were stripped and my tonneau cover kept coming loose. I bought these bolts cause they looked like the ones I had and they were perfect. They fit perfectly and have been holding my tonneau cover down great.

Didn't think it would work but it did.
