To properly align and adjust the lock rods on your DIAMONDBACK CVR-9 Heavy-Duty Truck Bed Cover, follow these steps. First, prepare for lock rod adjustments. Use a 7/16” socket to unbolt and reposition one bolt on each of the four lock-rod guide brackets to the second slot. If your plastic bed rail cap extends below the metal edge, trim it flush with the metal at each lock rod location. Next, adjust the lock rods. Use the provided hex key to loosen the set screws for the tail and cab panel lock rods. Ensure the Z bend orientation is maintained. With the handle closed, the rod tips shouldn't hit the bed walls, and with the handle open, they should clear the bed rails. Tighten all brackets with a 7/16" socket, pushing up on the bracket and applying downward pressure on the cover for a tight seal after aligning the lock rods in the closed position. Note that the panels might be stiff initially; leave them closed to allow the weatherstrip to break in. The cab panel has a safety spring lock handle to secure the lock rods. For the first two weeks, open the tail panel before operating the tailgate to prevent issues.
