Assembly and Installation
1. Locate the vertical support (stud) in the wall of the trailer.
Fasten two Mounting Brackets for each post to the side of
the trailer vertically and spaced accordingly for the length of
your side posts. Install the upper bracket just below the drip
rail where the three provided TEK screw fasteners will
penetrate the vertical support. (If through bolts are desired,
acquire necessary hardware locally). Applying a bead of caulk
between the mounting bracket and trailer wall will prevent
water infiltration (caulk not included). Repeat this process for
each of the side mounted posts.
2. In each bracket, assemble the bolts through the slots
into the double T-Nut loosely. Slide the posts (sold separately)
over the T-Nuts into position. Before tightening, use a tape
measure from the top of the post to the drip rail or upper
bracket to maintain consistent height of each of the side
mounted posts. (Note that you should not exceed the legal height
limits for the roads on which you will travel.)
If the optional Bow Stiffener was purchased, install it now, see instructions bellow.
3.. Place the Ladder Rack Bow across the top of
the trailer, insert a spacer (2x4) between roof and
Rack cross member. (For trailers under 6’ wide the
crossmember needs to be cut or replaced with a shorter
side mount post). Slide the eyebolts where you want
an attachment point.Loosely attach 2 long double
T-nuts to each rack corner with one bolt in each T-
nut, so that the T-nuts can pivot. Slide the
assembly to the desired height on the side
mounted post. Insert a second bolt in each T-nut. Check position with a tape measure
and tighten all bolts. Repeat this process to install a right and left rack corner at each
side mounted post.

Optional Edge guard installation
(sold separately)
Install the supports for the rear edge
guard on the outside of each rear post
(Post must be mounted within 24” of the
rear). Measure the distance between
the supports and cut the edge guard
tube approximately 1” shorter. Slide
the edge guard tube over the cross
angle. Fasten the cross angle in place
with the two mounting bolts. Cut the
excess length if desired.
Optional Bow Stiffener Installation
(sold separately)
Loosely assemble the T-nuts on the outside of the angle, slide to the center on the
bottom side of the Ladder Rack bow and tighten the bolts. The Bow Stiffener will
reduce the amount of flex in your Ladder Rack bow and nearly double the load
capacity. (take care not to overload the structure your racks are mounted to)
