ANSI Standards: M-Series locks meet all requirements for installations in doors and frames prepared in accordance with
ANSI specifications A156.13, 2005
Metal Doors: Suitable reinforcement is required to support lock case in center of door and to prevent door from compressing
when trim is tightened. (See ANSI A115.1)
Thick Doors: Locks for non-standard door thickness may require special instructions
Lead Lining: When M-Series locks are ordered with lead lining, add 56" (3) to the width of the mortise cut-out on the lock case cover side of
installation
Electrified Locks: Provisions must be made to route low voltage wire to the lock. Attach wires to the 6" (152) pigtail of the solenoid.
