INSTALLATION
ADJUST TRANSPORT LOCK
• If adjustment is required, loosen the two bolts on
both sides of the transport lock. This allows for up
to a 1/2" of adjustment from side to side in the
latch mechanism.
• Once the latch mechanism is in the correct position,
tighten the bolts.
• Once the transport lock has been adjusted, test its
functionality by shaking the step assembly to
simulate road vibration.
• Engage and disengage the transport lock to ensure
the latch flanges do not scrape against the
doorframe.
NOTE: To make further minor adjustments, it may be
necessary to loosen the original two fasteners installed
in the hinge plate. See Place Assembly Inside
Doorframe section.
Do not attempt to lock the step in place, as the latching mechanism may need to be adjusted to the proper left-right orientation
and tightened in position before using the transport lock. Attempting to engage the transport lock without proper adjustment
may cause damage to the doorframe or step assembly.
INSTALLATION
SECURE HINGE PLATE
• After adjusting the transport lock and with the step assembly in the upright stored position, secure the hinge
plate to the floor of the trailer using eight additional fasteners.
A. Depending on flooring material, use either #10 - 1 1/2" wood screws (wood floor) or #10 - 1 1/2" self-
tapping screws (laminate floor).
B. If necessary, use the horizontal slots to make additional small adjustments of the step assembly
positioning in the doorway.
• Extend the step assembly.
• Reinsert the two provided plastic caps to cover the access holes in the mounting plate.
