together, there is a LEFT & RIGHT FRONT, with
the Right marked with a GREEN dot on the
overlapping plate. There is a RIGHT & LEFT
REAR. The leg cups angle outward. Be sure the
connecting plates overlap, and bolt together with
bolts G, washers K and lock nuts N.
#2 = Slide the FRONT leg onto the front side
channel. There is a RIGHT & a LEFT.
Match to the correct side channel so that both
FRONT & REAR legs angle outward.
Insert the set screws P, but do not tighten yet.
#3 = Loosely attach the top CLAMP with
bolts F, washers K, and nuts N.
#1 = Cover entire swedge joints with
silicone sealant and attach the REAR LEGS
with bolts C, washers J, and nuts M.

#2 = Attach the Mount Plates on truck using either bolts D, washers J
and nuts M, or a combination of Clamps and Stake Pocket T bolts.
#3 = Measure the distance, center to center, between the
FRONT and REAR U-BRACKETS. Adjust the distance between
the FRONT and REAR LEGS to match that measurement.
Then set the rack on the truck and attach the rear legs first with
bolts A, washers H, and nuts L.
NOTE: If it is not possible to locate a second hole close to the front leg, or if you would like to
mount your rack without drilling into your truck’s bed rail, please see OPTIONAL MOUNTING
METHODS on the last page of these instructions. These options require accessory mount kits
purchased separately.
#1 = Position the Front Mount Plates on the truck bed rail so that they are as far forward as possible,
but make sure inserted bolt A is at least 1” clear of the cab of the truck.Position the Rear Mount Plates on
the truck bed rail so that the rear of the Mount Plate is even with the inside of the truck tail gate. Find the
pre-drilled hole in the footplate that is furthest from the leg and drill 3/8” hole through truck’s bed rail. You
must drill a second bolt hole through both the footplate and the truck’s bed rail. Locate this second hole as
close as possible to the front leg, but making sure you can access the end of the bolt underneath the truck’s
bed rail as necessary to put on the washer and nut.
NOTE: When using Stake Pocket T Bolts, it is convienient to locate the
Mounting Plates so that one of the pre drilled holes in the Mount Plate is
over the truck’s stake pocket.

SILICONE
SEALANT
Apply a healthy air tight bead of silicone around every swaged joint to prevent
moisture from leaking into and out of the joint. If this is not done properly, the
inside surface of the tubes can rust and rusty water can leak out. Maintain this
joint seal throughout the life of your rack.

When it is not possible to locate a bolt close to the front leg, use our
optional Stake Pocket T- Bolt Kit #31560.
The T-nuts will go into the stake pocket to secure the footplate to bed
rail, along with the hole drilled into the trucks’ bed rail through the
pre-drilled hole in the footplate. Complete instructions come with the
kit.
This plan is the NO DRILL ANYTHING solution.
These clamps allow you to bolt down the footplates to the trucks’ bed
rail without having to drill any holes in your truck or the footplate.
This kit is #31580.
