The XXL Bone Bracket is designed to accommodate the skull plates of antlered and horned species such as elk, caribou, buffalo, moose, and heavy-horned sheep. Like its smaller counterpart, the XXL offers complete customization of your trophy up and down to provide that perfect presentation. The XXL Bone Bracket can be assembled and hung in just a few minutes. Simply mount the wall plaque to a wall stud with the supplied screws, attach the skull plate adjuster to the arm, locate and drill two holes in the skull plate, and install two screws to attach the skull cap to the skull plate adjuster. Then just insert the tapered arm pegs into the wall plaque canisters, and make any final adjustments to the trophy positioning for the perfect display. Parts included are: 1 wall plate, 1 arm, 1 skull adapter, and all necessary hardware.
