8. (continued) Drill and attach middle crossbar / leg assembly
With a pencil or marker, draw lines from corner to corner on square outlined on the rail.
For best results, use a center punch to mark the intersection of the two lines before drilling.
Carefully drill (2) 3/8” holes straight up through the rectangle tube in each side. Note you cannot drill
down from the top as the round tube rail is in the way and will prevent drilling a straight hole.
Slide the front leg / middle crossbar assembly forward after drilling both sides.
Use (2) 3/8”-16 x 2” carriage bolts, (2) 3/8” split lock washers and (2) 3/8”-16 nuts to attach the front leg /
middle crossbar assembly to the top side railing. Repeat for other side. Finger tighten only.
9. Drill and attach rack brackets to truck bed.
Ensure legs and rack are square and rack is positioned correctly on the truck bed rails. Mark the hole
positions on all four legs (3 holes per leg bracket – 2 on top and 1 on the inside)
Examine the truck bed underneath the marked areas to see if access is available to attach nuts to bolts.
If no access is available, drill 1/4” dia holes and use 3/8” hex lag bolts with lock washers.
If access is available, drill 3/8” holes in all locations where marked. Using (12) 3/8-16 x 1-1/4” hex bolts,
(12) 3/8” split lock washers and (12) 3/8”-16 nuts, secure the rack to the truck.
10. Tighten all nuts and bolts
Tighten the rack attachment bolts installed in step 9 first before tightening any other rack bolts. Proceed
next to the HD brace nuts. Continue around the rack and tighten all remaining nuts and bolts securely.
Tighten until lock washers are flat but DO NOT OVERTIGHTEN!
