The QR Adaptor Plate for Compass and CX adds a quick-release interface to Miller's CX-based base plates, enabling secure mounting to monopods and lightweight rigs. It mounts beneath the CX and CXV base plates and provides both 1/4-20 and 3/8-16 threads, plus a 100 mm travel quick-release feature for rapid reconfiguration. The plate is lightweight, durable, and designed for fast transitions between tripod and monopod setups. No power is required and it adds minimal weight to the rig.
