M Series Mortise Lock

ANSI Grade 1 Heavy Duty

The M Series Mortise Locks are produced by I-TEK Metal Mfg Co. in Taiwan under ISO 9001 quality management, which is system certified by Underwriter Laboratories. I-TEK’s test facility complies with ISO17025 and it is certified by Intertek under a continuous re-inspection program.

Furthermore, Klacci is a registered member of Builders Hardware Manufacturers Association BHMA, as well as continuously ensuring that we follow up-to-date ANSI Standards with rigorous inspections by Intertek and Underwriter Laboratories. Our aim is to make our customers feel secure in the knowledge that high-quality products are provided.

Features

  • M 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).

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.

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

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

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

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

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

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

G Working parts are made of highstrength steel alloy.
