Before drilling it is best to make sure that the antler base is relatively flat. If there is jagged ridges or bone sand those areas flat.

Take your antlers and hold them up to the Buck Bracket product and check visually for how you want those antlers to sit when mounted.

Use the supplied drill bit with your order to drill into the base of your antler. Deer products need approximately 1/2" deep pilot hole, elk require about 1 1/2" deep.
