This Universal Quick Release Baseplate from Sirui integrates an ARRI dovetail plate, an Arca-Swiss plate, and a dual 15mm rod clamp onto a single mounting device for maximum compatibility. Attach rigs up to 33.1 lb onto the baseplate thanks to its multiple 1/4"-20 and 3/8"-16 threads, screws, and included Arca-Swiss quick release plate. Several locking levers make up the dual locking system to ensure your camera remains secure on the baseplate system. A dual 15mm rod clamp allows you to incorporate rod-based accessories like lens supports or follow focus motors.
