After removing the rail covers check the bottom
of the rails for any debris. The bottom of the
rails should be clean and dry. Wipe the rails with
denatured alcohol, this will help the mounting tape
adhere to the rails.
Mounting tape application.
Apply the mounting tape (B)
to the bottom of the cap rails staying 1/4” from the inside edge
of the side rails. Put a line of tape across the front bulkhead staying
just on the outside edge of the cap. Be sure the ends of the mounting
tape are butted up tight to the tape on the side rails (or even overlap).
There should not be a gap between the bulkhead mounting tape and
the side rail mounting tape.
Preparing the truck.
Clean the truck and rear window of the cab and the truck’s bed rails to remove all dirt and grime.
To help protect the truck’s bed finish lay a piece of carpet or cardboard down during installation. It is also recommended
that you tape off areas of the truck that could be impacted by the cap during installation.
Before beginning the installation check the bed to see
if it is square or true by measuring from right rear to
left front and left rear to right front. The length should be the
same when measured from the same points each way. If it is
not, keep this rule in mind: If the bed is out of square, or the
bed is not positioned squarely behind the cab, the cap must
still be positioned square with the rear end of the truck bed
for the door to operate correctly. This may cause positioning
difficulty if the bed is not square with the cab or out of square.
Using the welder’s clamps to hold the cap in place,
clamp the driver’s rear corner so the inside edge of the
door frame is lined up with the inside edge of the bed tailgate.
Do NOT overtighten clamps.
Place the cap (A) on the truck. Make sure that no part
of the truck cap is touching the truck bed surface!
If it is add more mounting tape as needed.
Repeat the process on the passenger side. You may
need to push in on the side of the cap to get the
proper position before clamping.
