From Manufacturer
The MOVE Quick Release Catcher System Set from Manfrotto is a unique circular quick release system set that uses a single intuitive gesture to operate—just drop the plate in and start shooting. The knurled twist lock collar can be turned to provide a more secure lock or twisted in the opposite direction to release the plate in a single movement. Precisely engineered technologies mean a lighter ergonomic design, suitable for use with tripod heads, sliders, tripods, stabilizers, and more. It is designed to work with the entire MOVE ecosystem of support products.
The compact circular plate features a 1/4"-20 threaded mounting screw and a storage space for a 3/8"-16 bushing adapter, so one will always be on hand if needed. It also incorporates an anti-rotation set screw to help secure any mounted head or device from coming unscrewed from the plate.
