sTEp 1:
Slide five clamps into each cargo rail. Evenly space the clamps along each side rail, leaving approximately 8” on each end if applicable.
See Detail-A for height placement of clamp.
sTEp 2:
Place front of side rails against front of truck box, flush with box rail and level with each other. Tighten the clamps starting at the tailgate
using a 9/16” socket.
sTEp 3:
For optimum latching performance and cover fit, side
rails must be level. To adjust rails, loosen clamp bolt and
reposition male clamps higher or lower. Tighten all clamps.
note:
For best clamping performance,
male clamp must be positioned in
the top groove as shown.
Horizontal sheet metal located
under the trucks side rail.
Detail-a
note:
Tighten clamps securly, 21 ft. lbs. of torque
is required per clamp.
note:
For best clamping performance, the female clamp must be positioned at a height
where the clamp touches the horizontal sheet metal on the underside of the truck rail.
This will help prevent the clamp and rail from slipping when an upward pull is applied.
