Another way to ensure proper fi t is to check the side to side play of the handle assembly at the canister and at the
tailgate end of the rails. There should be, at the minimum, enough play to allow the cover to move freely with no drag
and at a maximum 1/8 inch per side. More then 1/8inch per side may result in the cover opening unintentionally and
in severe cases it may fall between the rail tracks and damage the cover. There are shims on the brackets that can
be removed if the unit is too tight and shims in the hardware pack that can be added if too loose.

STEP 5: ATTACH THE PULL STRAP
Attach your pull strap to either of the clamps (left or righthand side) at the tailgate end of the rails by looping it
through the assembly and pressing the two velcro strips together. This will ensure the pull strap will always be in
easy reach when trying to close the cover.

Secure the rails to the truck bed by installing two clamp assemblies per rail. Slide the Clamp Grip onto the Rail at the
Clamp Relief and then slide it towards the Rail Bracket and Shim (Fig 4E and 4F). Then assemble the rest of the clamp
parts as shown below (Fig 4C and 4D). Be sure to use the long grip at the canister end (Fig 4D) of the rails and the
short grip at the tailgate end (Fig 4C).
Before tightening the rail clamps set the Rail End Caps about 1/16 inch from the tailgate. This space will allow for
overstroke when closing the tailgate. Once everything is square tighten the Rail clamps completely but do NOT
tighten over 120 inch-pounds!
Finally, check for proper spacing by measuring between the rails at the canister and the tailgate end of the rails (Fig
4A). The measurements should be equal to or less then those in Fig 4B. The Rail Brackets and Shims have been
pre-installed to achieve the proper Between the Rail dimension (BR) when placed on an average factory truck bed.
However, not all truck beds are average dimensionally and some have optional plastic caps or over the rail spray-in
liners.
