PDQ MR276 MFSF Privacy w/Indicator Function Mortise Lockset - Grade 1
The PDQ MR276 MIA (often ordered as MFSF for the Miami lever on an F-Series Sectional (round rose, wrought trim)) is a premier Grade 1 Privacy 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. This lockset suits restrooms, locker rooms, changing rooms, and single-occupancy spaces where staff and visitors need to see at a glance whether a room is in use. A visual occupancy indicator on the outside displays VACANT or OCCUPIED.
Constructed with a heavy-duty 12-gauge cold rolled steel mechanism, the MR276 adds a visual occupancy indicator to the trusted MR privacy function. The Miami (MIA) lever offers a clean, architectural aesthetic in a US32D Satin Stainless finish. Its "return-to-door" design is not only ADA compliant but also serves as a safety solution by preventing clothing, bags, or straps from snagging on the hardware in busy corridors.
ANSI Function F22 (w/Indicator): Privacy w/Indicator
The Privacy w/Indicator function operates the latchbolt from either side and locks the outside lever by an interior thumbturn, with an emergency coin-turn release on the outside; an outside indicator window shows the room's occupancy status:
- Latchbolt operated by lever from either side.
- Emergency coin turn outside unlocks outside lever.
- Thumbturn inside locks/unlocks outside lever.
- Closing door unlocks outside lever.
- Rotating inside lever unlocks outside lever.
- 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:
- At-a-Glance Occupancy: The outside indicator window reads VACANT or OCCUPIED, reducing accidental door 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.
- Anti-Sag Lever Technology: The MR Series utilizes independent, high-tension spring cartridges to ensure the Miami lever remains perfectly level throughout its multi-million cycle life.
- 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.
