The Vocas 15mm LW Swing Away Bracket attaches directly to the rear of the MB-430 Matte Box and allows the user to mount the matte box onto 15mm lightweight rods. When the red knob of this swing away bracket is twisted, the matte box is released from its locked position, allowing the user to swing it away from the lens. This swing away bracket can also be fitted with a 19mm rod adapter, allowing the MB-430 Matte Box to be used on 19mm rods.
