1" 1/4 (CALLED) 42mm MITCHELL THREE LEGS

The Gripfilm 42mm Mitchell Three Legs kit gives you a 1-1/4" (called) speed rail tripod base for Mitchell-mounted cameras and heads — 250mm main ring, 185mm O.D. black Mitchell base, and all the black anodized tubes, starter pins, and clamping levers needed to build a complete three-leg Mitchell support structure from 42mm speedrail.
