Step 3 Crossbar assembly
Crossbar width fit
Because truck beds widths can taper front to back, each crossbar will be set specifically to match where it is mounted
on the bed. The crossbar width will be 5-1/4” shorter than the length measured.
Using the measurements from step 2,
Front Legs span ___________________ - 5-1/4” = _________________
Rear Legs span ____________________ - 5-1/4” = _________________
Slide the 1-3/4” inner crossbar tube into the 2” out crossbar tube as shown until they measure the length from above.
Temporarily secure the two crossbars together by wrapping tape around the end of the 2” outer crossbar and 1-3/4”
inner crossbar.
Using the 2” tube bolt holes as guides; mark the center of the holes using a center punch.
Drill the holes marked with a 3/8” drill bit on both sides. Remove tape that was temporarily holding the two crossbars
together.
Align the bolt holes of both tubes. Apply a small bead of silicone around the bolt holes on the larger tube.
Insert the 3/8”-16 x 2-3/4” bolt with a flat washer through the crossbar.
Secure the bolt with a flat washer and 3/8”-16 nylon insert lock nut.
Repeat for other bolt hole.
Place the end caps on the ends of the crossbar.
Apply silicone to the gap between the inner and outer crossbar to seal out water and reduce wind noise.
Repeat step for other crossbar.
