We were substituting a steel version of the mounting plate, which is pictured. The mounting plate we are selling are Liberty Hardware Easy-Clip concealed hinge system. This 3mm mounting plate is for face frame cabinets.
These hinge mounting plates are for converting overlay hinges to face-frame mounting. Not for inset hinges.
Featuring a 3 mm rise that reduces the overlay by (big surprise) 3 mm.
Overall dimensions:c-c 1-1/4"(32mm) x W 2-3/8"(49.8mm)x W small end 11/16" (17.5mm) x H 7/16"(10.7mm)
Overlay dimension will be either 1/2" or 3/4" depending on which mounting plate is used.
The 3mm plate will achieve an overlay of 1/2" on a door in which the bore distance is 2 to 3 millimeters using a full overlay hinge. The bore distance is the distance from the edge of the door to the edge of the 1-3/8" cup that is drilled in the back of the door.
The picture shows the part in steel, whereas the one we are selling are die cast, but functions the same
