PDQ MR174 OJEJ Grade 1 Privacy with Thumbturn on Both Sides Function Mortise Lock - Heavy Duty
The PDQ MR174 OJEJ is an architectural-grade, Grade 1 Privacy with Thumbturn on Both Sides Function Mortise Lock for high-traffic commercial environments. It pairs the Orlando (OJ) lever -- a straight lever with a simple rounded end -- 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 rooms that need privacy control from either side, where a thumbturn on the inside or the outside locks the outside lever. 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 uses a heavy-duty forged brass and stainless steel internal mechanism 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: Privacy with Thumbturn on Both Sides
The Privacy function operates the latchbolt from either lever and locks the outside lever by a thumbturn on either side; closing the door or rotating the inside lever unlocks it:
- Latchbolt operated by lever from either side.
- Thumbturn outside locks/unlocks outside lever.
- Thumbturn inside locks/unlocks outside lever.
- Closing door unlocks outside lever.
- Rotating inside lever unlocks 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.
- Two-Sided Privacy: A thumbturn on either side locks or unlocks the outside lever; closing the door or rotating the inside lever releases it.
- 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.
