The SHAPE Mini Composite Shoulder Pad is a comfort-padded and comfort-shaped shoulder pad for the back of your camera rig. Outfitted with a 15mm-mount SHAPE Rod Block, the pad attaches right onto a pair of 15mm rods, slides into the best position on them, and tightens in place by a quality lever. It also has a black Screw Knob under which you can add a SHAPE Counter Weight or a SHAPE Back Pad, both optional and both back-supported accessories that work as extensions of the shoulder pad. The Screw Knob's screw is a 1/4"-20 screw. If you remove the Screw Knob, you'll have yourself a 1/4"-20 screw-hole to add various 1/4"-20-mount accessories into.
