This Quick Release Plate is a camera-specific plate, designed to securely hold a Nikon D300 or Bronica GS-1 camera. The raised lip on the plate prevents rotation of the camera body. It is compatible with any "Arca-Swiss" type quick release system (e.g. Arca-Swiss, Foba, Graff, Wimberley, etc.). Precision machined from T-6 aluminum, this high-quality plate features a satin black anodized finish, and is "made in the USA".
