Designed for the Novoflex Q=System, the QPL 4 Quick Release Plate is a 6.1"-long Arca-type plate featuring three camera screw positions, along with two 1/4"-20 screws and two 3/8" screws, for a variety of mounting options. A safety pin feature is integrated into the design, which prevents the camera or other mounted equipment from accidentally slipping when used in conjunction with Q=System mounts.
