PDQ MR141 KJSJ Grade 1 Storeroom with Deadbolt Function Mortise Lock - Heavy Duty
The PDQ MR141 KJSJ is an architectural-grade, Grade 1 Storeroom 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 Sectional (round rose) in a US32D (630) Satin Stainless finish, and is engineered to exceed the rigorous standards of BHMA Series 1000. It suits storerooms, utility rooms, and secured supply openings that need a keyed, always-locked outside lever plus a deadbolt, where the inside lever retracts both the latch and the deadbolt in a single motion for egress.
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: Storeroom with Deadbolt
The Storeroom with Deadbolt function keeps the outside lever rigid and locked, retracts the latchbolt and throws the deadbolt by outside key or inside thumbturn, and retracts both the latch and the deadbolt from the inside lever in a single motion:
- Latchbolt operated by lever from inside.
- Key outside retracts latchbolt.
- Key outside extends/retracts deadbolt.
- Rigid outside lever.
- Inside lever simultaneously retracts latchbolt and deadbolt.
- Auxiliary latch deadlocks latchbolt.
- Thumbturn inside extends/contracts deadbolt but doesn't effect outside lever.

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 MR141 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.
