INSTALLATION PROCEDURE
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 spacer in,
sticking it to the truck bed.)
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. 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.
3. Tighten the clamps using a 1/2” socket.
