A high quality heavy duty commercial grade mortise lock series (Grade 1) capable of meeting the requirements of a vast array of lever and knob designs. Available standard as a 2 34" backset, they may also be had in 2 12, 3 34, 5 and 6" backsets. They incorporate a standard 1 14" wide faceplate and are designed for doors 1 34" thick and greater. (A 1" wide faceplate is also available). A universal curved lip strike for hollow metal and wood frame construction conforms to ANSI Standard A 115.1, 4.875 × 1.25"(124 × 32 mm) lip to center. Flat lip, special length and custom strikes may also be ordered to accomodate various project conditions and requirements. Locks and strikes are field reversible and available in a variety of keyed and non-keyed functions and include emergency egress functions where applicable.

Our heavy duty mortise locks employ high carbon steel compression springs for long life and durability of service. Hubs are fabricated of oil impregnated, copper infiltrated sintered steel, for additional strength and positive latch retraction. Cases are designed to accomodate thru-bolting trim for positive alignment with the lock case. Locks are regulary furnished with a 34" throw 2-piece mechanical heavy-duty anti-friction latch bolt to meet U.L. requirements for use on a pair of fire doors.

Dead bolts are fabricated with hardened steel inserts. Faceplates and strikes are fabricated standard in non-magnetic 304 alloy Stainless steel. Brass or bronze substrates and most decorative finishes may be had on a special order basis. Our locks are U.L. Listed (3 Hour) for use on fire doors and can be specified for applications in offices, schools, hospitals, hotels, and commercial buildings, as well as residences.

All Locksets may be electrified for electromechanical function requirements. Solenoids are U.L. tested for cycle life, low operating temperature, shock and fire hazard qualifications.

Electromechanical locks are designed for intermittent or continuous duty and are available in either 12 or 24 VAC, and have been tested in accordance with the American National Standard for Mortise Locks and Latches and meet or exceed the ANSI A 156.13-1987 specifications, making them the best choice for any building where safety, security and design compatibility are prime considerations.
