The MH665Q Arca-Type Quick Release Plate for MH665 & MH5012 QR Assemblies from Giottos can be mounted on the MH665 and MH5012 QR bases. A semi-circular tightening wing around the camera screw lets you lock down the camera, as well as pre-orient the camera in your desired position, before attaching the plate. The plate features a camera screw and rubber grips.
