What brand tonneau is this?

The rail that the cover latches down to detached from the bed rails. It looks like it connects by those holes you can see in the first image. I don’t know what type of fasteners those are though. They aren’t bolts as far as I can tell.

 

Get off my lawn!

Welcome.

 

I was gunna say Bakflip too or whatever parent comapny produces all the different brands that are essentially the same

 

What are the plastic corners?

 

Here's pic of broken corner your missing

 

Awesome thank you guys!

 

This should help you. Don't know if yours is MX4, or G2, but looks like older MX4.

 

here is the underside. It does not have the sliding lock for the props in this position as I’m seeing on most of the models spec sheets.

 

Bakflip tonneau cover. The rivets need to be redone. Had the same problem with mine.

 

Any advice on how to do that? Did you replace the rails or opt to fix it yourself?

 

Bought a rivet gun and some rivets from harbor freight. Removed the old ones and put in new ones. And if you know that Bakflip part number of the cover, you can order spare parts to replace it too

 

Older style didn't have that sliding lock for prop.
