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.
