NOTE: The edge trim should not be installed over the vertical
angle brackets in the front corners of the bed.
NOTE: If you are reusing the original edge trim you will need
to install a double sided foam tape such as 3M 06382 to the
backside of the edge trim pieces.
12. Mark the lengths of edge trim to be used on the right and
left sides of the liner. Do not use edge trim under the
support tube brackets on soft top models or under the
tonneau cover bow bracket on hard top models. Once
the proper lengths of edge trim have been marked, cut
the edge trim to length. Install the edge trim onto the top
edge of the bedliner, but do not remove the adhesive film
backing yet. The edge trim must be installed loosely
onto the top edge of the bedliner. A 1/8" gap should be
left between the inside edge of the trim and the top of
the bedliner to allow for expansion.

13. When all the pieces of edge trim are in their correct
location, remove the adhesive film backing from one
piece of trim and press it into place. Repeat until all the
pieces of trim are in place.
14. Clean the vehicle tailgate. Center the tailgate cover side
to side and push the cover forward until the cover is
tight against the top of the tailgate. Using the holes in
the upper corners of the cover, mark the tailgate and drill
two 5/32" holes in the tailgate for the cover retaining
screws. Redrill the holes in the tailgate cover only out to
3/8". Fasten the tailgate cover to the tailgate by install-
ing the screws and washers. Snap a plastic cap over each
washer.
15. Clean the tailgate along the bottom edge of the cover
with rubbing alcohol to insure proper adhesion of the
edge trim. Install the edge trim leaving a 1/8" gap
between the inside edge of the trim and the cover for
expansion. Remove the adhesive film backing and press
the trim into place.
