PDQ MR136 OJSJ Grade 1 Dormitory/Exit Mortise Lock - Deadbolt Privacy with Emergency Egress
The PDQ MR136 OJSJ is an architectural-grade, Grade 1 Dormitory/Exit Mortise Lock for demanding, high-traffic commercial and institutional openings. It pairs the Orlando (OJ) lever -- a straight lever with a simple rounded end -- 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 is a definitive solution for university housing, military barracks, and multi-family residential openings where security, occupant privacy, and code-compliant emergency egress are all required. Its "return-to-door" design is ADA compliant and helps prevent clothing, bags, or straps from snagging on the hardware in busy corridors.
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 F13: Dormitory / Exit Security
The ANSI F13 Dormitory/Exit Function combines a latchbolt with a heavy-duty keyed deadbolt for occupant privacy plus single-motion emergency egress from the inside:
- Latchbolt operated by lever from either side.
- Key outside extends/retracts deadbolt.
- Thumbturn inside extends/retracts deadbolt.
- Extending deadbolt locks latchbolt and outside lever.
- 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 MR136 integrates easily into existing master key systems and supports Interchangeable Core (IC) for rapid re-keying.
- Anti-Sag Lever Technology: The Orlando lever is supported by an independent, high-tension spring cartridge that returns the handle to a level horizontal position every time.
- 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.
