Repeat procedure for other upper ladder
section rail.
Using a hacksaw or tube cutter, remove the ends of the
lower ladder section at the mark on each rail. Insert the
respective nut-leaf ends of the die cast hinges installed
on the upper ladder section into each rail of the lower
ladder section. Drill a 13/64" hole through the rail and
hinge end approximately 1/2" from the rail end (it may be
easier to pre-drill a starter hole through the rail before
inserting and drilling the hinge.) Place a #10-24x1-1/2"
bolt through each set of holes and fasten each with a
#10-24 nut with nylon-lock insert. Tighten the bolt to 16-
18 in-lbs until snug to surface (see Diagram #9). Be
careful not to over-tighten the bolt or tube may be
crushed.
Repeat procedure for other upper ladder
section rail. Do not tighten the hinge bolt at this time.
The hinge must be able to flex while being mounted to
prevent binding in the ladder.
The ladder is provided with (4) standoff tube assemblies
that are to be located along the ladder rail and aligned
with the vehicle's intended backer locations. In most
cases, the standoffs will be located evenly spaced from
the roof line to the ladder bottom or in the immediate
vicinity above and below a rear window. The standoffs
should be installed in pairs which align horizontally on
each respective ladder rail. Once locations have been
determined, drill 17/64" hole through the center of each
rail. Place a standoff between the ladder rail and the
vehicle's rear wall, and then align the hole in the standoff
with the drilled hole in the rail. Place a #1/4-20x3" round-
head machine screw through the hole on the other side
of the rail and thread it into the inserted nut located
inside the end of the standoff tube. Tighten the bolt to
16-18 in-lbs until snug to surface (see Diagram #10). Be
careful not to over-tighten the bolt or tube may be
crushed. Repeat for each standoff assembly until all are
attached to the ladder. Set the ladder back into position
with its handles resting on the roof.
How to mount the ladder to your RV...
Begin mounting the ladder by starting at the top and
working your way down.
MAY CAUSE PERSONAL INJURY OR DEATH
Proper fastener specification is based on the framing
or backer material provided in the RV's sub-structure.
Refer to your RV dealer, local installer or vehicle
manufacturer for recommended fastener specification,
size, and type suitable for this type of installation
Place a screw into both mounting holes in each
respective triangular mounting bracket and secure to the
roof.
Depending on the tools used, all of the mount
holes may not be accessible. Securing the brackets may
require you to swivel the ladder or separate the ladder
from the brackets in order to access the mount holes.
First secure the bracket with a screw through the
accessible mounting hole. If ladder cannot be positioned
to access the second mount hole, then remove the bolt
holding the ladder to each bracket, remove the ladder
and then place a screw through each bracket's second
mounting hole. Replace the ladder into the brackets with
the respective removed bolt-and-nut assembly.
