The "Shoulder" is the key part of the Fourth Arrow Camera Arm System. It is the joint between the base and the arm. The Fourth Arrow Shoulder allows you to affordably own a base for every treestand set. The shoulder slides firmly and locks into the base. After the shoulder is leveled with the included tool, the Arm may be placed in the socket of the shoulder and you are ready to video your hunt! The Fourth Arrow Shoulder is the single largest innovation change that sets Fourth Arrow apart from other camera arms.
Compatible with the Stiff Arm, Carbon Arm, Triple Arm, and Stiff Arm Pro.
