Add an extension arm for a handgrip or other accessories on your shoulder rig with this 8Sinn Side Arm for Shoulder Rigs . The aluminium arm is made up of two sections, and each section features a rosette on either side. The sections connect using one set of rosettes and a thumbscrew, which creates a rotating joint.
One end attaches to your rig with a thumbscrew, and the rosette on the other end features a thread for attaching a handgrip or other rosette accessory. There are two 1/4"-20 threads on the longer section that allow you to attach additional accessories.
