The Sirui TY-5D II Arca-Type Pro Quick Release Plate is designed specifically for the Canon 5D Mark II 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-5D II plate's screw fits the camera's 1/4"-20 thread. The aluminum-alloy plate has raised front and back edges that prevent the camera from twisting as you position your head.
