10 Select the best mounting option for your application.
NOTE: All welding should conform to American Welding Standard D1.1 welding procedures.
!
CAUTION:
Prior to mounting the MPS 350, verify that the fuel tank(s) on the
truck is more than 10 feet 6 inches (3200 mm) from the rear of the truck. If the
distance is less than 10 feet 6 inches (3200 mm) contact your Trinity Highway
Products Representative about various extensions.
Option A This option uses a ½” (12 mm) plate welded across the back of the truck frame
rails as shown in Figure 9.0 below. Mount Tabs welded to the plate provide
attachment points for the MPS 350 Bumper. The length of the Mount Tabs
should allow ½” (12 mm) of clearance between the Lower Bumper Cross
Member of the MPS 350 Bumper and the Mounting Plate. The Mounting Plate
should be braced to the truck frame using the “C” Channels provided with the
MPS 350. Attach the Channels to the truck frame as far forward as possible
following the truck manufacturer’s recommendations regarding attachment
methods.

Option B
This option involves welding the MPS 350 Bumper directly to the truck frame
rails. Welding on the “C” Channels provided can extend the rails. Adequate
bracing should be welded to the Lower Bumper Cross Member extending
forward as far as possible for attachment to the truck frame rails.
!
CAUTION:
Leave adequate (4” minimum) clear area directly
behind the Bumper Assembly and directly in front of the Shear
Bars to ensure that the Shear Bars are not obstructed during an
impact. Failure to follow this warning will result in damage to the
truck and the MPS 350. See drawing 33599/SS-621 located in
the Appendix for more information.
Contact your Trinity Highway Products Representative to discuss any special
mounting requirements for your particular application.
