Bi-Directional Body Plate for the Canon EOS 10D Sculptured to match the contour of the camera base and allow access to the battery. Carefully machined to be smooth to the touch. Mount the camera in either direction or use our C-90 right angle bracket because of our unique bi-directional design. Switch from collared lenses to un-collared lenses without repositioning the tripod head. Fully ARCA compatible like all 4th Generation Design plates. Mounts with the standard 1/4"-20 screw in the camera. Wrench provided. Weight: .9 ozs.
