Place one leg close to the rear corner of the box using a

square to get a proper vertical setting. The closer the legs

are mounted to the rear corner, the more stable the box will

be.

NOTE: Leg can be mounted up to 3" maximum from

rear corner of box (see figure 2 inset).
NOTE 1: The foot of the Leg must be squarely mounted

on or between the tops of the floor ribs.
6.

Mark both leg foot holes on the floor of the truck bed, and

both leg top holes in the end of the box.

Repeat leg placement and marking process at the other

end of the box.

Using the bed lip as a guide, mark the underside of the

box at the point where the box and bed lip meet at the

ends of the box, and in the center of the box if installing

a 272/290/291/296/297/372/390/391/396 (see Figure 1).

If there is a stake pocket in the truck bed below the point

where any of the 6" long lines intersect the truck bed, mark

the truck bed at that point.

Remove the box and turn it over. Mark the box in two

locations for drilling (four for Models 272/290/291/296/297/

372/390/391/396). Mark these holes 1/2" inward of the

marked line, and on the 6" long lines (see Figure 1).

10.

If a stake pocket interfered with any "J" bolt mounting lo-

cation, 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 floor marks with a 1/2" drill bit. Install Blind Fasten-
ers in the floor (See Blind Fastener Instructions on the back
page).

11.

Fasten the Legs to the box.

12.

Install the “J” Bolts through the holes you have drilled,

and attach the Plastic Retaining Washer, Fender Washer
and Nylon Lock Nut (see Figure 3.). Tighten the nut to the
top threads of the “J” Bolt 1/4 turn into the nylon.

13.

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.

NOTE: 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.
14.

Fasten the Leg feet to the floor.

15.

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.

NOTE: Periodically check the tightness of "J" bolts to
insure proper attachment.
16.

Snap the Cap Plug into the bottom hole (plug may be

pulled when cleaning inside the box).
