INSTALLATION PROCEDURE

1

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.
