STEP 5: INSTALLING CLAMPS
HARDWARE USED:
JACKRABBIT ® SERIES 4
Before shimming and installing the rail clamps make sure the canister is centered between
the truck bed rails.
Not all truck beds are square. Shims may be required to keep the rails parallel and from
bowing out when the clamps are tightened.
If there is a space greater than 3/8” (in most cases at the cab end of the rails) in between
the rail and the truck bed, then slide the adjustable clamp shims (Figure 5A) down the rails
6-12” from the canister stops (installed in Step 3).
Loosen the bolt on the clamp shim and slide the bracket up against the truck bed. Then
tighten the bolt so the shim is held tight in place.
If there is less than 3/8”, the adjustable clamp shim is not needed. Insert plastic shim(s) to
level the rail when proceeding with installing the clamps (Figure 5B). Add plastic shims to
equalize the distance between rails at front and rear to obtain no more than a 1/4” side to
side play in between the cover and rails.
Slide the front clamp rail grips (Figure 5C) 6-12” inches from the canister stop, or if the
adjustable clamp shim was installed, 1” from that shim on both the left and right side rails.
(Note: If two clamp rail grips are 3/4” longer they should go on each rail fi rst (one
left, one right) and be closest to the canister) Slide rear clamp rail grips 6-12” from the
tailgate on both the left and right rails.
At this time you must Install the tailgate end of the pull strap to the underside of the drivers
side rail using the #8-32 x 3/4 machine screw located at the tailgate end on the underside
of the rail. (Figure 5D)
Assemble the pivot arms to the clamp rail grips and snug the bolts on the clamps so that the
rails rest fi rmly against the truck bed. (Figure 5C) Close the tailgate and position the rails
with a 1/16” gap from the tailgate.
Measure the distance between the rails at the canister and tailgate. This distance should be
the same to allow your cover to operate properly.
Once everything is square tighten the Rail clamps completely.
