PDQ MR278 PFEF Privacy with Deadbolt w/Indicator Function Mortise Lockset - Grade 1
The PDQ MR278 PHL (often ordered as PFEF for the Philadelphia lever on a forged F-Series escutcheon) is a premier Grade 1 Privacy with Deadbolt w/Indicator Function Mortise Lockset engineered for demanding commercial environments. While typical commercial locks are rated for one million cycles, the PDQ MR Series is tested to over 11 million cycles -- extending the hardware lifespan by 11 times the industry standard. It suits restrooms and private rooms that need a privacy deadbolt with an occupancy indicator.
Constructed with a heavy-duty 12-gauge cold rolled steel mechanism and a 1-inch throw investment cast stainless steel deadbolt, the MR278 adds a occupancy indicator to the trusted MR function. The Philadelphia (PHL) lever offers a clean, architectural aesthetic in a US32D Satin Stainless finish. Its "return-to-door" design is not only ADA compliant but also prevents clothing, bags, or straps from snagging on the hardware in busy corridors.
ANSI Function F02 (w/Indicator): Privacy with Deadbolt w/Indicator
The Privacy with Deadbolt w/Indicator function operates the latchbolt from either side, adds a deadbolt thrown by interior thumbturn with an emergency coin-turn release outside, and shows a VACANT/OCCUPIED status on the outside:
- Latchbolt operated by lever from either side.
- Emergency coin turn outside retracts deadbolt.
- Thumbturn inside extends/retracts deadbolt.
- Indicator, outside -- (VACANT/OCCUPIED).
Finish availability: This indicator function is not offered in 626 (US26D Satin Chrome). The base finish is 630 (US32D Satin Stainless), with premium architectural finishes (605, 606, 612, 613E, 622, 629) also available.

Engineered Solutions for Commercial Security
The PDQ MR Series addresses the specific technical and safety challenges of modern facilities:
- Occupancy Indicator: The outside indicator window reads VACANT / OCCUPIED, which reduces accidental openings on restrooms, locker rooms, and single-occupancy spaces.
- Vandal-Resistant Spindle: The "weakened spindle" design is a critical security solution. If the exterior lever is subjected to extreme torque or a hammer attack, the spindle breaks cleanly to prevent damage to the internal 12-gauge steel case, keeping the lock secure.
- Extreme Weather Durability: Certified for High Velocity Hurricane Zones (HVHZ) with a design load rating of +/- 70.0 PSF, this lockset provides the structural integrity necessary for coastal buildings.
- Fire Safety Compliance: With a UL 3-hour fire rating, this lockset ensures that commercial doors remain a reliable fire and smoke barrier, protecting occupants and property.
