STEP 4. Place the box in position on the bed side, support the rear of the box with scrap lumber or cribbing, and square the box to
the bed. Level the box so the top is horizontal when viewed from the rear.
NOTE: Fasten the leg mounting feet directly to the floor, not on bed liners or floor mats.
STEP 5. 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.
STEP 6. Mark both leg foot holes on the floor of the truck bed, and both leg top holes in the end of the box.
STEP 7. Repeat leg placement and marking process at the other end of the box.
STEP 8. 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 272-3-02/290-3-02/291-3-02/296-3-02/297-3-02/372-X-02/390-X-02/391-X-
02/396-X-02 (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.
STEP 9. Remove the box and turn it over. Mark the box in two locations for drilling (four for Models 272-3-02/290-3-02/291-3-
02/296-3-02/297-3-02/ 372-X-02/390-X-02/391-X-02/396-X-02). Mark these holes 1/2" inward of the marked line, and on the 6"
long lines (see Figure 1).
STEP 10. If a stake pocket interfered 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 floor marks with a 1/2" drill bit. Install Blind Fasteners in the floor (See Blind
Fastener Instructions).
STEP 11. Fasten the Legs to the box.
STEP 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.

STEP 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.
STEP 14. Fasten the Leg feet to the floor.
STEP 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.
STEP 16. Snap the Cap Plug into the bottom hole (plug may be pulled when cleaning inside the box).
