The HCO Universal Camera Mounting Bracket is made of the heavy gauge steel and powder coated to prevent rust. It can be bolted or strapped to the tree or other applicable surfaces. The ball has a 1/4-20 stud attached to it. The bracket will work with cameras that have the pem stud in the back or on the bottom. Most scouting cameras on the market are currently using this tap size on the pem nut embedded in the case on the camera. This is the most common tripod thread type.
