Features

• M1 Series is a heavy duty commercial mortise lock. All bolts are made of stainless steel with most working parts inside the case made of high strength steel alloy. It is UL listed for 3-Hour fire rating and meets/exceeds the ANSI/BHMA A156.13 Grade 1 specification.

• The lock case has 3-5/8" (92mm) center cylinder to spindle dimension, allowing the lock to retrofit most manufacturers' mortise lock without or with minimal door prep modification thus maximizing the replacement capabilities.

• The lock case is non-handed; reversibility without disassembling the lock case allows a full complement of functions. A single lock case for all trims allows excellent trim design combination flexibilities.

• A special feature of this lock is that the lever or knob is retained by lever/knob keeper. The material of the lever/knob is pressure zinc cast standard. Steps of installation are minimal with rose and escutcheon snap-on parts. Consult factory for other trim materials (Stainless Steel or Solid Brass).

A Solid one-piece latch made of stainless steel. The anti-friction curve design provides enhanced life cycle with reduced wear to the strike, adding strength and security.

B Working parts are made of high-strength steel alloy.

C Spindle designed to break when an excessive force is applied, thus protecting the lock case from further damage.

D Spring cassette design enhances protection against lever sagging, providing a firm and positive horizontal lever return position.

E Solid brass or pressure zinc cast lever retained by knob keeper, outside lever cannot be removed from outside.

F High-precision standard or I/C cylinders offer high security and reliability.

G Varied sectional and escutcheon trim options available to meet different needs and preferences.

H Cylinder to spindle center is 3-5/8” (92mm) which enables retrofit in most manufacturers’ mortise locks.
