OConnor O-Grips feature smooth-functioning, single-handle ball joints with a maximum payload capacity of 44 lbs (20 kg), making them ideal for use with both smaller and larger cameras, and are capable of fitting all three standard rod systems (15mm & 19mm Studio, and 15mm Lightweight) via the single, easy to use O-Grips bridge. Each grip is fully adjustable and is capable of a half sphere of stepless articulation. The O-Grips can be locked with one hand while operating most shoulder-mounted camera systems--no tools required. A 3/8" stainless steel top screw and 3/8" bottom thread enable attachment at many points on a camera and allow the addition of different accessories to the O-Grips for maximum versatility and functionality.
