The Old Style with Pins and New Style with Teeth are not interchangeable
This lock case will only replace the Current style Roto Locks.
Faceplate Width: 5/8 inch (16mm)
Faceplate Length: 15-3/4 inch (400mm) -- old-style faceplate length was 13-3/8 inches
Backset: 1-3/4 inch (45mm)
NOTE: This lock is also available in 1-3/8 (35mm) backset
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 Roto gear lock box works on roller and tongue version locks.
NOTE 1: After you get the new lock installed, the latch and deadbolt are located in slightly different places than the old style (see additional images); the differences is about 25/32 inch, so you can move the strike plate or make the slot longer.
NOTE 3: this gear works ONLY with the 15-3/4 inch faceplate - Will NOT directly replace the older style gear with the shorter 13-3/8 inch faceplate; The entire lock will have to be replaced.
