INSTALLATION PROCEDURE
1
1. Slide the clamp assembly (3 per side) into the Utility rail, position one front, one center and one rear.
2. Attach both left and right side rails to the truck bed. The end of the mounting rail with the drain tube fitting
will go towards the cab of the truck, position flush to bulkhead. Position the top edge of the mounting rail
flush to 1/8" above the top edge of your truck bed rail.
3. Using three (3) clamps per side attach the rail to the bed, position the clamps adjacent to each of the black
rail spacers. (Tip: Mount the center clamp first but do not tighten completely. This will give you the ability to
adjust the rail as the outer clamps are attached)
4. Tighten the clamps using a 1/2” socket. Install the bulkhead seal to the top of the front rail of the truck bed
and cut to length.

damage to you or your property.
