The SHAPE Quick Release Plate Adapter gives you the freedom to remove your camera from your tripod, stabilizer, or support rig without having to detach it from the plate. It includes a Manfrotto 501PL style sliding plate, meaning that the plate will also work with any Manfrotto system that accepts a 501PL plate. A 1/4"-20 screw and a 3/8"-16 screw are included so you can use the plate with various cameras. 1/4"-20 and 3/8"-16 threaded holes on the underside of the adapter allow you attach the plate to a tripod, stabilizer, or support rig. Three bubble levels are available to assist in leveling your camera.
