4.4.2 Installing Floor Extension
CAUTION
If a galvanized floor extension and dock bumpers
are being installed, the galvanized material must be
removed prior to welding. Refer to the Installation
manual for the proper procedure.
There is also a special procedure to follow when
welding galvanized material to a stainless steel truck
body sill.
Follow all OSHA and other workplace safety standards
when grinding or welding galvanized steel, which
creates zinc oxide fumes. Always grind the coating
off in the area to be welded and provide adequate
ventilation to avoid breathing the fumes.
Always wear the proper breathing protection when
grinding or welding. Use a ventilation or vacuum
system to remove any contaminated air from the work
area.

truck body. If a bolt-on method is preferred, refer to
section “4.7 Bolt-On Floor Extension” on page 25 for
the complete procedure.
1. If desired, spray the parts of the truck body near the
areas to be welded with anti-splatter spray.
2. Find and mark the center of the truck’s rear sill and
the center of the floor extension with a white marker.

3. Install the floor extension.
a. Use a white marker to also mark the finish weld
locations with a repeating 2 inch continuous weld
with a 4 inch gap. Make your marks from both
ends inward toward the middle.
b. Using a lifting device, center the white mark on the
floor extension with the white mark on the truck
body.

c. With the center of the floor extension level with the
floor of the truck, begin tack welding at the center
and work outward. Make sure the extension remains
level and flush with the floor of the truck bed.

must be straightened as it is installed.
CAUTION
Tack welds must be strong
enough to hold the weight
of the floor extension (up
to 300 lbs.) until the final welds are completed.
Insufficient welds may not hold the floor extension,
resulting in possible bodily harm.
