The Petite Clamp is a “pass through” baby 5/8" (16mm) clamp with a set-screw to lock it in place and a single mounting location to accept all accessories designed for the 3- & 4-Way Clamp System. This little gem will enable you to mount a series of light modifiers in a row in front of a light fixture, a whole variety of grip accessories in the middle of a Grip Arm, etc. Its applications are only limited to your imagination.
