Product Manual

Place the mounting pads in position on top of the truck bed as shown in gure below. Tape the mounting pads to the truck

bed in a few places to keep them from moving or falling off when installing the box.

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.

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.

Mark both leg foot holes on the oor 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.

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 272-3-02, 290-3-02, 291-3-02, 296-3-02, 297-3-02, 372-X-02,

390-X-02, 391-X-02, 396-X-02. 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 272-3-02, 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 page 3).
