PDQ MR158 KJEJ Grade 1 Dormitory Mortise Lock - Dormitory Deadbolt Security
The PDQ MR158 KJEJ is an architectural-grade, Grade 1 Dormitory Mortise Lock for demanding, high-traffic commercial and institutional openings. It pairs the Ball Knob (KJ) knob -- a rounded ball knob -- on a J-Series Escutcheon in a US32D (630) Satin Stainless finish, and is engineered to exceed the rigorous standards of BHMA Series 1000. It is a proven solution for dormitory rooms, apartments, and multi-family residential openings where key-controlled deadbolt security and single-motion egress are both required.
Built to withstand punishing institutional use, the MR Series drives a 1" throw investment-cast stainless steel deadbolt and a 3/4" anti-friction stainless latchbolt from a heavy-gauge steel case seated deep in the door pocket -- providing significantly higher forced-entry protection than standard cylindrical locks, the industry standard for schools, hospitals, and government offices.
ANSI Function F11: Dormitory Security
The ANSI F11 Dormitory Function combines an always-active latchbolt with a deadbolt keyed from both sides and single-motion egress from the inside lever:
- Latchbolt operated by lever from either side.
- Toggle locks/unlocks outside lever.
- Key outside extends/retracts deadbolt.
- Key inside extends/retracts deadbolt.
- Inside lever simultaneously retracts latchbolt and deadbolt.
- Auxiliary latch deadlocks latchbolt.

High-Performance Solutions for Building Security
The PDQ MR Series Mortise Lock addresses the most demanding commercial infrastructure challenges:
- Maximum Forced Entry Resistance: The steel case fits deep into the door pocket, providing superior resistance against "kick-in" attacks and physical tampering versus single-point cylindrical locks.
- Keyed Deadbolt Security: A 1" throw investment-cast stainless steel deadbolt, keyed to the exterior, adds a dedicated second point of security beyond the latchbolt.
- Simplified Key Management: Provided with a Schlage C (SCC) compatible cylinder, the MR158 integrates easily into existing master key systems and supports Interchangeable Core (IC) for rapid re-keying.
- Vandal-Resistant Engineering: The trim features a break-away spindle design; extreme torque or a hammer attack breaks the spindle without compromising the internal locking mechanism.
- Architectural Integration: The Satin Stainless (US32D) base finish offers a clean, professional appearance and excellent corrosion resistance; premium finishes (605, 606, 612, 613E, 622, 629) are also available.
Finish availability: This J-Series lockset is offered in 630 (US32D Satin Stainless) as the base finish, plus premium architectural finishes 605, 606, 612, 613E, 622, 629. It is not offered in 626 (626 is an F-Series finish).
*Ball knobs are not ADA compliant. The KJ ball knob does not meet ADA/ICC A117.1 operable-hardware requirements (no tight grasping/pinching/twisting). For ADA-governed openings, specify a lever trim.
