The Gitzo GS5370C Quick Release Plate is a 1.5" square plate that comes with one standard 1/4"-20 camera screw and one 3/8"-16 screw. It is a "C" type plate as designated by Gitzo's 3 different profiles.
As of October 2009, the GS5370C is compatible with the 2285MB, GS3760C, and GS5760C quick release adapters, the G2272M Low-Profile Head, all the current ballheads except for the Off-Center Heads, and the G2180 Fluid Head.
This plate replaces Gitzo's discontinued G2285M/14 plate.
