NOTICE:
Depending on the bolt pattern used to install
the Ultrex Mount to the Outer Plate of the Quick Release
Bracket, the Right Side Plate may need to be removed to
access the mounting holes in the base of the Mount. Use
a #2 Screwdriver to remove the Side Plate if necessary.
INSTALLATION OF THE NEW MOUNT
a. Place the Ultrex Accessory Mount (Item #2) on an
elevated, level surface such as a workbench or the
tailgate of a pickup. The Mount, as removed from the
box, should be in the deployed position.
b. A 5/16” Allen Screw is located on the Mount. The
Screw is on the opposite end of the Mount from
the hinge. The hinge allows the Mount to stow and
deploy. Remove the 5/16” Allen Screw with a 1/4”
Allen Wrench. Retain the two 1/4-20 X 3/4 Screws
(Items #10) secured to the Mount with the Allen
Screw for later in the installation. Retain the Allen
