Sirui TY-D700 Arca-Type Pro Quick Release Plate is designed specifically for the Nikon D700 DSLR camera. Featuring Arca-style grooves, the plate fits the Sirui G20, K20x and K30x heads and also quick-release clamps from several other manufacturers, such as Acratech, Foba, Graff and Wimberley. The TY-D700 plate's screw fits the camera's 1/4"-20 thread. The aluminum-alloy plate has a raised back edge that prevents the D700 from twisting as you position your head or when the head is in 90deg. tilt mode.
