Please review all pictures - If your lock body looks like the pictures you have an old-style lock, which is obsolete and must be replaced with new-style lock body or a complete replacement.

NOTE: If replacing an old-style Roto with new-style Roto, the gear box is 23/32 inches different.
It will be necessary to lower, or cut out, the strike plate about 3/4 inch to match with the new latch and deadbolt.
Also, the door will need to be notched about 3/4 inch to accommodate the new multipoint lock body.
Remember to measure the backset either 1-3/8 (35mm) or 1-3/4 inch (45mm) when ordering.

Replacement Options:
Option 1 - Complete replacement See # 4990220 (45mm)(Replacement Instructions)
