M Series Mortise Lock
ANSI Grade 1 Extra Heavy Duty
- M Series is a extra 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).
Clutch Operation
An optional clutch operation function is available for the outside trim. When locked, the door handle will disengage from the mortise lock’s mechanism and turn freely, preventing damage of the lock if an excessive force is applied on the handle and protecting your lock from forced-entry attempts.
Enhance your door lock security with this feature and feel at ease knowing that your door is even more secure than before.
