The Skull Hooker Big Hooker is a fully adjustable European mounting bracket that does not require drilling into the skull. The prongs adjust the skull up and down, while the arm adjusts right and left. This gives you the ability to display your trophy at the best angle. The Big Hooker skull hanger is designed specifically for large to extra-large sized skulls including, elk, bison, moose, caribou, grizzly/brown/polar bears, domestic steer and other exotic larger game such as kudu, giraffe, wildebeest, oryx, stag, cape buffalo and many more large trophy game species worldwide with an elk sized skull or bigger. The Skull Hooker prong fits naturally into the back of the skull, which cannot be cut or altered around the natural hole or cervical joint at the back of the skull.
