New style Roto MP lock gear box to replace old style multipoint locks.
The dead bolt is in a new location. Aprox 1/8" lower than the old-style.
This Roto gear lock box works on roller and tongue version locks.
The door will need to be notched out 23/32 inch to accept the position of the new style gear box.
Also, the strike plate will need to be lowered 23/32 inch to line up with the latch and dead bolt.
This replaces only the 15-3/4 faceplate and will not work with the 13-3/8.
As another replacement option, an entire, new stainless steel multipoint lock is available, please call for details.
Priced and sold each.
