What is the difference between the Falcon M and MA series mortise locks?
M is discontinued and replaced by the MA.
Here are some of the major differences between the M and MA-Series.
Lever mounting post holes - Locations have changed on door template. (12 and 6 o'clock for M lock, MA lock is approx 1 and 7 depending on handing). If upgrading to the MA lock, Escutcheon and Rose plate will cover changes to the door.
Re-handing procedure - M lock requires taking lock case apart and moving internal pieces. MA lock changes handing by moving screws to one side of the case (similar to L9000)
Trim design - The trim is not backwards or forwards compatible between the locks.
Inside lever - The inside lever on the M series has an allen head screw. The MA does not have this feature.
Cylinder cams - The old cam will not work in the MA lock. Information on the MA cams can be found here.
Lock chassis - The MA lock chassis is a completely different design than the M. None of the parts are backwards compatible.
