This Universal Quick Release Baseplate Kit from Sirui includes the same ARRI dovetail plate, Arca-Swiss plate, and dual 15mm rod clamp compatibility in the standalone baseplate version while adding a Y-shaped lens support and two 15mm rods. Attach rigs up to 33.1 lb onto the baseplate kit 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 and two included carbon fiber rods allow you to incorporate rod-based accessories like the included Y-shaped lens support. The lens support is height-adjustable up to 2.2" and accommodates lenses 2 to 5.5" in diameter.
