These swingaway brackets are designed for use with trunk pads for lateral thoracic positioning. The brackets have a button-release for ease of use and a vinyl cover to cover edges of internal brackets. The bracket can be used with the button on the top or flip it over and use it with the button on the bottom. We identify the left and right brackets with the button on the top, if you plan to flip the bracket over with the button on the bottom please order accordingly. This bracket requires the use of Swingaway Lateral Extrensions to interface between the swingaway bracket and the trunk pad. The part is fabricated primarily from stainless steel.
