Fold Cover up to Attach
Attach Cover/Drain Tubes
Once in the fully open
position place a front
retainer clamp, flat washer,
lock washer and the star
knob on the front mount-
ing bolt underneath the
cover and hand tighten.
Be sure the front retainer
clamp is clamping to the
side rail correctly. Test the
cover again for proper
operation, adjust as
needed, then tighten the
star knobs.
Attach the drain tubes to
the fittings at the front of
the bed rail and position
the tubes to divert water
out of the truck bed. This
can be done by placing
the tube behind a bed
liner, through an existing
hole in the bed, or by
drilling a 5/8” hole in the
bulkhead.
Once the cover is
located correctly, fold
the cover up to the
open position. Pull
the release cables on
the rear two panels
and turn the red
handle to the open
position to fold up
completely. Take care
to fold it gently so the
position of the cover
is not disturbed.
Note: If you choose to place the tube behind your bedliner, be sure your
drain holes in the bed are not clogged.
Note: If you choose to drill a hole, be sure to clean up the metal shavings.
