Install your front mounting bracket using the measurements on Page 6,
Figure 4. Using a tape measure place the rear end of the front bracket 16" from the inside wall of the
bulkhead. Follow the same steps on the opposite side.
Now using C clamps provided place 5/16 x 1 1/4” bolt with 5/16” lock washer and 5/16” washer
through the hole in the front bracket and thread in the C clamp as shown on Page 6, Picture A. Each side will
require 2 clamps. Do not completely tighten down the clamps at this point, rather insure that they are secure
using a ½”socket or wrench. You may need to make some slight adjustments once the cover is in place in
order to line up the cover with the bed and avoid rubbing. After you have test fit the cover and feel that the
brackets do not require any further adjustment you should then tighten down front bracket clamps to the
proper tightness (See footnote below). On Page 8 you can find instructions as to how best to test fit your
cover and how to make any adjustments to your front brackets (if necessary).
You are now ready to install your cover and test for proper fit with the bed rails of your truck. Mounted
to your covers are both a left and right 4 bar hinge. See Page 6, Figure 5, Picture B. With some assistance, lift
the cover up and over the bed bringing the 4 bar hinges over the front brackets see Page 6, Figure 5, Picture
C. Your front brackets have 2 mounting posts, see Page 6, Figure 5, Picture D. The 4 bar hinges attached to
your cover have 2 slots on each that slide over the mounting post fixed to the bracket on your truck. Set the
cover down sliding the slots over the post on both sides. See Page 6, Figure 6, Picture E.
The cover should be resting on the bed rail of your truck with a larger than normal overhang at the
tail gate. See Page 7, Picture F. From the rear of the truck you should now be able to push the cover forward
sliding the mounting post into the slots of the 4 bar hinge. See Page 7, Picture G. Your cover should now be
locked into place and your are ready to tighten the twist knobs on the 4 bar hinge into the front brackets.
Only hand tighten this and secure as much as possible. See Page 7, Picture H. You may need to remove the
cover to make adjustments to the front bracket to line up the cover with the bed.
Footnote: The bolts should be tightened securely, stop tightening at the first sign
of the bracket distorting.
