PDQ MR126 PFEF Passage Function Mortise Lockset  - Grade 1

The PDQ MR126 PHL (often designated with PFEF for the Philadelphia lever on a wide F-Series Escutcheon) is an architectural-grade Passage Function Mortise Lockset engineered for the highest traffic commercial environments. While many Grade 1 locks are tested to one million cycles, the PDQ MR Series has been tested to over 11 million cycles, exceeding BHMA standards by 11 times. This makes it the premier solution for interior corridors, common areas, and office partitions in hospitals, universities, and government facilities where hardware failure is not an option.

Constructed with a 12-gauge cold rolled steel mechanism, this lockset provides a level of structural integrity that standard cylindrical locks cannot match. The US26D Satin Chrome finish over a solid forged brass base ensures a professional aesthetic that is highly resistant to the harsh cleaning chemicals typical of healthcare and industrial settings. Designed for longevity and ease of use, the Philadelphia lever is fully ADA compliant, offering a comfortable grip and a return-to-door design that prevents accidental snags in busy thoroughfares.

ANSI Function F01: Passage / Always Active

The ANSI F01 Passage Function is specifically designed for openings where latching is required for privacy or fire code compliance, but locking is not necessary.

• Unrestricted Flow: Both the interior and exterior levers are always active. Turning either handle retracts the latch bolt at all times, facilitating seamless movement through high-traffic zones.
• Low-Maintenance Security: By eliminating the cylinder and locking toggles, the MR126 removes the most common mechanical failure points, significantly reducing long-term maintenance costs and the need for re-keying.
• Fire & Smoke Barrier: Despite being a non-locking set, the 3/4" investment cast stainless steel latch bolt ensures the door remains positively latched, satisfying the requirements for a 3-hour fire-rated barrier.
• Emergency Egress: This function provides a "one-motion" exit and entry, ensuring that even in low-visibility or high-stress situations, occupants can move through the opening without hindrance.

Technical Specifications

Engineered Solutions for Institutional Durability

The PDQ MR Series addresses specific facility management and security pain points:

• Eliminate Lever Sag: High-frequency passage doors often suffer from drooping handles. The MR126 features an independent, high-tension spring cage for each lever, ensuring the Philadelphia handle returns to a perfect horizontal position for the life of the building.
• Vandal-Resistant Security: Even in a passage function, the lock case features a weakened spindle design. This prevents vandals from damaging the internal 12-gauge steel mechanism if they attempt to apply extreme torque to the exterior lever.
• Hurricane & Severe Weather Protection: Certified for High Velocity Hurricane Zones (HVHZ) with a design load rating of ± 70.0 PSF, this lockset provides the structural strength needed to keep doors secured during extreme wind events.
• Safe Egress & Snag Prevention: The Philadelphia (PHL) lever is engineered with a return-to-door curve. This is a critical safety solution in hospitals and schools, preventing clothing, medical equipment, or fire hoses from catching on the lever during an emergency.
• Domestic Sourcing Compliance: Assembled in the USA, this hardware meets the requirements of the Buy American Act, making it suitable for federal, state, and municipal government infrastructure projects.
