Does some know what type of tonneau cover this is?

Bought my first Tacoma TRD Pro yesterday . Had an aftermarket Blackhorse roll bar which looks great! But has a tonneau cover that I haven't been able to identify. Seems a bit cheap, I am able to close it but not really lock it in closed position. Once closed but when I am driving and apply the brakes it opens and rolls itself back in (slams). The truck is only 6 months old and this does not look worn so I am guessing it's very low quality (it does say made in China for whatever that is worth). I am trying to figure out what kind of locking mechanism it is but I haven't been able to disassemble, the lock may have a stripped bolt which continues to turn.

If anyone knows where I can find info on this cover please let me know. Thanks!
