PDQ MR178 HJSJ Grade 1 Privacy with Deadbolt Mortise Lock - Privacy Deadbolt (Handed, Non-Keyed)
The PDQ MR178 HJSJ is an architectural-grade, Grade 1 Privacy with Deadbolt Mortise Lock for demanding, high-traffic commercial and institutional openings. It pairs the Houston (HJ) lever -- a solid, substantial straight lever -- 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 non-keyed privacy solution for restrooms, dressing rooms, and private offices where an inside thumbturn throws a deadbolt for privacy and an outside emergency coin-turn allows entry in an emergency. This is a handed function and is not field reversible. 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 F02: Privacy with Deadbolt
The ANSI F02 Privacy with Deadbolt Function operates the latchbolt from either side and adds a privacy deadbolt controlled by an inside thumbturn, with an outside emergency coin-turn release:
- Latchbolt operated by lever from either side.
- Emergency coin turn outside retracts deadbolt.
- Thumbturn inside extends/retracts deadbolt.
- Not field reversible.
- Specify handing.

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.
- Privacy Deadbolt: A 1" throw stainless steel deadbolt is thrown by the inside thumbturn for privacy, with an outside emergency coin-turn release for authorized access when needed.
- Anti-Sag Lever Technology: The Houston 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.
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).
Handing: This is a handed function and is Not Field Reversible. The lock is built to a specific door hand at the factory. Specify the door hand when ordering -- LH (LHR) or RH (RHR). Refer to the diagram above to determine the hand of your door.
