PDQ MR128 KJEJ Grade 1 Institution with Deadbolt Function Mortise Lock - Heavy Duty
The PDQ MR128 KJEJ is an architectural-grade, Grade 1 Institution with Deadbolt Function Mortise Lock for high-traffic commercial environments. 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 suits institutional and correctional openings that must be locked and unlocked by key from both sides, with a deadbolt also thrown by key from either side.
Built to withstand punishing institutional use, the MR Series uses a heavy-duty forged brass and stainless steel internal mechanism and a 1-inch throw investment cast stainless steel deadbolt inside a deep mortise cassette -- providing significantly higher forced-entry protection than standard cylindrical locks, the industry standard for schools, hospitals, and government offices.
Function: Institution with Deadbolt
The Institution with Deadbolt function keeps both levers rigid, operates the latchbolt by key from either side, and adds a deadbolt thrown by key from either side:
- Key outside retracts latchbolt.
- Key inside retracts latchbolt.
- Key outside extends/retracts deadbolt.
- Key inside extends/retracts deadbolt.
- Rigid outside lever.
- Rigid inside lever.
- 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 cassette fits deep into the door pocket, providing superior resistance against "kick-in" attacks and physical tampering versus single-point cylindrical locks.
- Positive Deadlocking: The auxiliary deadlatch engages when the door closes, preventing "loiding" or shim attacks against the latch bolt.
- Simplified Key Management: Provided with a Schlage C (SCC) compatible cylinder, the MR128 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.
