INSTALLATION PROCEDURE

1. 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.
2. Position the top edge of the mounting rail flush to 1/8" above the top edge of your truck bed rail. Starting
with the center clamp (one of the smaller clamps) install the rail, but do not tighten completely. Install the
other small clamp towards the front of the rail. Install the larger clamp at the rear of the rail, place the back
portion of the clamp into the stake pocket
For GMC 6.5’ Beds Only - Stick the rubber spacers between the plastic bed rail cap and the bed rail, adjacent to the
front and center clamps. (Identify the location of the spacers by holding the mounting rail up to the bed rail of the
truck and marking the location of the clamps on the truck. Pull out on the plastic bed rail cap and slide the the
spacer in, sticking it to the truck bed.)
4. Tighten the clamps using a 1/2” socket.
