The Cambo CS-153 Rod Clamp Triple Dual/Perpendicular (15mm), with the CS-M1 or CS-M2 tripod mount, allows adjustment of the distance between the optical center of the lens and the rods. It holds the rod 60mm apart and symmetrical to the optical axis. The mount can be mounted directly to the CS-P1 shoulder pad. The wing knob features a lock that prevents it from falling off the unit when unloosening the clamp. Made of precision milled high grade aluminum, the clamp has a black anodized finish.
