11. Drill and attach middle crossbar / front leg assembly
Ensure the entire rack and legs are square to the bed and vehicle. Adjust if needed.
Mark the location of the square holes in the ribbed middle crossbar end brackets on the underside of the
rectangle side rail tube. For best results use a pencil or marker and trace the outline of the square holes
onto the rail. Repeat for other side.
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 lower 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. If access from beneath is not possible or space is inadequate for drilling. Remove
(3) 3/8”-16 x 1-3/4” carriage bolts holding the round tube in place. Slide the round tube until
enough clearance is gained to drill the (2) 3/8” diameter holes through the lower rail rectangle
tube. Move the round tube back, reinsert the carriage bolts and tighten.
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.
12. Tighten all nuts and bolts
Tighten the rack attachment bolts installed in step 10 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!
