Step 8 (continued) Front Crossbar assembly
Center the front middle crossbar tube between the front rail crossbar adaptors. For best results, use a tape measure.
Temporally secure the middle crossbar to front rail crossbar adaptors with tape. This will keep the middle crossbar in
place while drilling holes to secure it to the rail adaptors. Tighten the hardware for the front rail adaptors.
Locate the center of the front middle crossbar marked holes and use a center punch. Drill the 3/8” holes on both
sides. Repeat for all holes.
Secure with (4) 3/8”-16 x 2-3/4” bolts, (8) flat washers and (4) 3/8”-16 nylon insert lock nuts.
and apply a small silicone bead around the bolt holes before putting on the flat washers.
Remove the tape and seal the gap between the crossbars on both sides with silicone.
