The JAG35 Shoulder Pad v2 is an aluminum pad with a foam cushion and a 15mm rod clamp that efficiently tightens onto rods by only one knob. The aluminum portion is wide, long, and weighty enough to effectively support pretty much any rig and camera. The foam cushion is just as large and accordingly affords comfort in supporting the weight of a rig. The aluminum is anodized for a smooth finish. Six 1/4" threads run along the length of the aluminum for accessories.
