The LP-CTMX is custom-designed to fit the Canon Tripod Mount Ring from before 2002, such as found on the 70-200 F2.8 non-IS lenses.
It is important to make sure your lens ring is NOT stamped with "CANON TRIPOD MOUNT RING B", as it will not fit this version.
Made of 6061 aluminium with a hard anodised finish, the LP-CTMX is supplied with a 1/4"-20 mounting screw and built-in anti-twist flanges that prevent the plate from moving once installed. There is still 1" of clearance left on the plate to allow installation of a Jobu Design quick-release flash bracket.
