PDQ MR138 PFSF Institution Function Mortise Lockset - Grade 1
The PDQ MR138 PHL (often ordered as PFSF for the Philadelphia lever on an F-Series Sectional (round rose, wrought trim)) is a premier Grade 1 Institution 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 is engineered for institutional openings that require key control from both sides of the door.
Constructed with a heavy-duty 12-gauge cold rolled steel mechanism, the MR138 provides a formidable defense against unauthorized entry. The Philadelphia (PHL) lever offers a clean, architectural aesthetic in a US26D Satin Chrome 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 F30: Institution
The Institution function keeps both levers rigid and operates the latchbolt by key from either side:
- Key outside retracts latchbolt.
- Key inside retracts latchbolt.
- Rigid outside lever.
- Rigid inside lever.
- Auxiliary latch deadlocks latchbolt.

Engineered Solutions for Commercial Security
The PDQ MR Series addresses the specific technical and safety challenges of modern facilities:
- 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 Philadelphia lever remains perfectly level throughout its multi-million cycle life.
- Simplified Key Management: Provided with a Schlage C (SCC) compatible cylinder, the MR138 integrates easily into existing master key systems. It also supports Interchangeable Core (IC) options for rapid re-keying.
- 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.
