2. Upright Installation
Position the nylon insert lock nuts inserted the step above so that they are placed 2.5” apart. Make sure that the nylon portion of nut is facing
inward toward the truck bed.
Orientate the uprights so that the top surfaces face into the truck bed and slide the uprights into the channel and position so that the lower holes
line up with the nylon insert lock nuts.
Assemble the upright to the channel with the ¼-20 x ¾” button head screw, lock washer and flat washer. Repeat for three remaining uprights.
3. Upright assembly
Assemble the upright as shown below by threading the ¼-20 x ¾” button head screws so the backing plates are held in place, allowing a gap
between the uprights and backing plates.
Repeat for gussets and gusset backing plates.
