PDQ MR176 PFEF Privacy Function Mortise Lockset - Grade 1 

The PDQ MR176 PFEF is a premium Grade 1 Privacy Function Mortise Lockset engineered for unmatched longevity in high-use environments. While standard commercial locks are rated for one million cycles, the PDQ MR Series is tested to over 11 million cycles, providing 11 times the mechanical life of typical Grade 1 hardware. This makes it the ultimate security and privacy solution for restroom facilities, dressing rooms, and private offices in hospitals, schools, and government institutions.

Constructed with a 12-gauge cold rolled steel mechanism and a 1-inch throw investment cast stainless steel deadbolt, the MR176 provides superior structural integrity. The Philadelphia (PHL) lever features an architectural return-to-door design that is fully ADA compliant, ensuring accessibility while preventing clothing or equipment from snagging. Finished in US26D Satin Chrome, this lockset offers a clean, professional aesthetic that is highly resistant to the rigorous cleaning protocols of modern facilities.

ANSI Function F22: Privacy Security with Emergency Override

The ANSI F22 Privacy Function is designed for non-keyed interior doors that require a high degree of privacy coupled with fail-safe emergency access.

• Dual Latching Security: The lock features both a 3/4" latchbolt for standard closure and a 1" deadbolt for enhanced privacy.
• Privacy Projection: Occupants engage the deadbolt from the interior via a thumbturn. Once projected, the exterior lever becomes rigid, signaling the room is occupied and preventing entry.
• Emergency Access: In the event of an emergency, authorized personnel can retract the deadbolt from the exterior using a small screwdriver or emergency tool through the coin-turn/emergency release on the escutcheon.
• Single-Motion Egress: Turning the interior lever retracts both the latchbolt and the deadbolt simultaneously. This "one-motion" exit is a critical life-safety requirement, ensuring occupants can exit instantly without fumbling with thumbturns.

Technical Specifications

Engineered Solutions for High-Frequency Use

The PDQ MR Series addresses the specific technical and maintenance challenges of large-scale facilities:

• Eliminate Hardware Fatigue: With an 11-million cycle rating, this lock solves the problem of "lever droop" and mechanical failure in high-traffic restrooms, significantly lowering the total cost of ownership by extending replacement intervals.
• Structural Vandal Defense: The trim features a weakened spindle design. If the exterior lever is subjected to extreme torque or physical abuse, the spindle breaks cleanly to protect the internal 12-gauge steel mechanism, maintaining the integrity of the lock case.
• Fire & Life Safety Integration: Despite being a privacy set, the MR176 is UL 3-hour fire rated. It ensures that even private rooms act as effective smoke and fire barriers while providing safe, single-motion emergency egress for occupants.
• Architectural Consistency: Using the Philadelphia (PHL) trim allows facility managers to maintain a uniform look across the building, matching the privacy sets on restrooms with the keyed mortise locks used on offices and storage areas.
• Antimicrobial Protection: Available with an optional antimicrobial coating on the US26D finish, this hardware serves as a proactive health solution by inhibiting the growth of bacteria on high-touch surfaces in public restrooms.
