End Caps
Place Ladder Rail Assembly
on Overhead Rack
Place the Ladder Rail Assembly on the Overhead
Rack with the Extension over the cab and the
Ladder Rack T-Bolts aligned with the holes in the
plastic corners on the Overhead Rack. Make sure
that the Button Head Cap Screws face up.
Make sure that one of the Extension T-Bolts is over
the cab of the vehicle and the other one is centered
between the Overhead Rack braces.
Secure Ladder Rail Assembly
to Overhead Rack
Slide the Rails forward or back until they are in the
desired position. Secure them to the Overhead Rack
with 5/16" Washers and Adjustable Handles.
Start the Adjustable Handle on the T-Bolt then lift the
handle and ratchet it the rest of the way down.
Repeat this with both Rails.
If you have trouble installing the Adjustable
Handles, start the Adjustable Handle on
the T-Bolt, then lift up on the handle and use a fl at
screwdriver to run the internal screw down.
