Bed rail clamp?

4 of these clamps were in the bed rails when I bought the truck. Not sure if these were used for a canopy or not but I'm looking into buying a canopy off a guy who probably can't find the clamps. It's a Leer 100xr I believe from 2012. Will these be of any use?

 

I have a LEER 100xl and had a LEER 100r and I've never seen those types of clamps. I'd go to the nearest LEER dealer or maybe online, how much could they be.

 

They look like the same sort of clamps that came with my tonneau cover, i'm not sure whether or not the canopies use those though

 

They are clips for a tonneau.

 

Ok thanks for clearing that up. I'll stop by a canopy shop and pick up some proper clamps.
