Download TOOLS REQUIRED FOR ASSEMBLY: 7/16″ wrench or socket 3/8″ wrench or socket #2 Phillips screwdriver Tape measure. The Bedlocker is designed to carry rainwater from the cover into the canister and then out through the drains. Most truck models have standard OE drain holes or plastic/rubber access ports in the front of the truck bed. Check to make sure your truck has the OE drain holes so that drilling into the sheet metal is not required. If drilling is necessary, be sure to check the underside of the truck bed for the best location. The holes should be located near the side and as far forward as possible. Use a drill bit suitable for sheet metal (such as a taper drill or step drill). Drill drain tube clearance holes at 3/4″ (19mm). This will need to be done before installing the cover. STEP 1: REMOVE CONTENTS & PLYWOOD PACKAGING Remove the canister and top cover from the box. Remove components from inside the canister. Perform a quick inventory to insure all parts are there. Using the wrench or socket remove the 2 bolts holding the plywood packaging supports on the ends of the canister. Discard plywood packaging supports and bolts.
