The Photo Clam PC-D300-UP Mounting Plate is specifically designed for the Nikon D300/D700 Battery Grip. Attach the camera's grip directly to the dovetail plate, which is compatible with Arca-style quick-release clamps.
Machined in the Korea from aircraft-grade 6061 T6 aluminum, the PC-D300-UP plate features a stainless steel screw. The plate has a lip that keeps the attached D300 or D700 from twisting. Holes at either end of the plate surface accept the attachment of a camera strap.
