Installing “J” Bolt
Note:
If a stake pocket interferes with any “J” bolt mounting location, it will be necessary to drill the box with a 1/2" drill for that “J” bolt,
and to drill the stake pocket at the mark with a 1/2" drill bit, with the top of the hole even with the bottom edge of the bed lip.
Drill all box marks with a 3/8" drill bit. Drill the oor marks with a 1/2" drill bit. Install Blind Fasteners in the oor.
Fasten the legs to the box. Install the “J” Bolts through the holes you have drilled, and attach the plastic retaining washer, fender
washer and nylon lock nut. Tighten the nut to the top threads of the “J” Bolt 1/4 turn into the nylon.
Stand the box upright and turn the “J” bolts to the side so they won’t interfere when placing the box on the bed of the truck. Set
the box in place on the truck bed.
Use vinyl tape as a barrier between the J-bolt and the aluminum
truck bed.
ALUMINUM TRUCK BED INSTALLATION:
When placing the box back in position, if it was necessary to drill a stake pocket, that “J” bolt will have to be held on an
angle from the underside of the box and guided into the hole in the stake pocket.
Fasten the leg feet to the oor. Turn the “J” bolts so they are under the lip of the bed. Pull the “J” bolt up until it contacts
the lip of the bed. Push the plastic retaining washer down, using the fender washer, so the “J” Bolt is held in position.
Tighten the nylon lock nut, making sure the “J” Bolt hook remains under the lip of the truck bed.
Periodically check the tightness of “J” bolts to ensure proper attachment.
Snap the cap plug into the bottom hole (plug may be pulled when cleaning inside the box).
