The QR90N Quick Release Assembly with QR Plate from Xiletu is an Arca-type quick release set that includes a classic knob-type receiver clamp and a 3.5" quick release plate. The clamp features dual bubble levels, a precision numbered scale for repeatable results, a 1/4"-20 mounting socket, and a hollowed-out design for reduced weight. It also has two additional 3/8"-16 and two 1/4"-20 threaded mounts for a variety of custom mounting options.
The included 3.5" quick release plate has a 1/4"-20 camera mounting screw with D-ring and slotted mounting options. It has multiple screw positioning slots for precise mounting options, plus dual safety screws to prevent the plate from accidentally releasing from the clamp mechanism prematurely.
