STEP 7: INSTALLING THE CLAMPS
Slide the Clamp Grip onto the Clamp Extension from the tailgate to the canister (Fig 7A). Next install the set screw to
lock the Clamp grip to the Clamp Extension with a 1/8” Allen Wrench (FIG 7B).Then assemble the rest of the clamp
parts as shown (Fig 7D or 7E). Be sure to the proper clamp combination for your truck. Figure 7D is the clamp
assembly for trucks without the Deck Rail System Track and Figure 7E is for trucks with the Deck Rail System Track.
Now tighten your clamp bolts with a 7/16” Nut Driver.
DO NOT TIGHTEN OVER 120 INCH POUNDS!
Finally, check for proper spacing by measuring between the rails by attempting to insert the BR Gauge in between the
rail metal and the handle stop (Fig 7F). You can also check the between the rail measurement at the canister and the
tailgate end of the rails. The measurements should be equal to or less then those in Figure 7C. The Clamp Extensions
have been pre-installed with brackets and shims 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.
