Take one upright and insert into the front
leg socket assembly. Tighten the 3/8-16
x 1" thread cutting bolt installed in Step
1 in the front mounting bracket. Take one
extension and insert it into the upright. After
tightening at the desired location, seal the
joint between the two tubes with the provided
silicone sealant. Take the ladder stop, one
3/8-16 x 3/4" carriage bolt, one 3/8" at
washer and one 3/8-16 nylon lock nut and
install onto the upright. Take the one strap
and install it onto the bracket.
Installing the Rear Upright
Take the remaining upright and insert into
the rear leg socket assembly. Tighten the
3/8-16 x 1" thread cutting bolt installed in
Step 2 in the rear mounting bracket.
Take the remaining extension and insert it
into the upright as shown in Step 3. After
tightening at the desired location, seal the
joint between the two tubes with the provided
silicone sealant. Take the remaining ladder
strap and install it onto the bracket as shown
in Step 3.
Installing the Rope Cleats
The two rope cleats are to be mounted where desired
on the upright.
Apply sealant around holes before assembling.
Securing a Ladder to the Rack
Carefully place a ladder on the rack, and check door
entry and head clearance. If clearance is ample, and
if desired, the uprights may be shortened as long as a
minimum of 2" above the cab roof is maintained, see
Step 4. Remove and cut the uprights if desired. Note
that you need to cut from the bottom of the upright.
Double check the measurement before cutting. Secure
ladder with the provided ladder straps when transporting.
Secure or remove ladder straps when not being used.
