PDQ MR116 PFSF Grade 1 Office Mortise Lock - Heavy Duty Commercial Security
The PDQ MR116 PFSF is an architectural-grade, Grade 1 Office Function Mortise Lockset engineered for high-traffic environments where both security and flexibility are paramount. Featuring the ergonomic Philadelphia (PFSF) lever design, this lock is part of the BHMA Series 1000 elite hardware category, meaning it is built to survive over one million cycles. It is the definitive solution for private offices, consultation rooms, and executive suites that require a robust locking mechanism that can be easily toggled between "secure" and "accessible" states.
Designed as a high-performance commercial security solution, the MR Series mortise chassis is housed in a heavy-gauge steel cassette that fits deep into the door's edge. This provides vastly superior resistance to "kick-in" attacks and prying compared to standard cylindrical locks. The PFSF lever is supported by independent, high-tension spring cartridges, ensuring the handle remains perfectly horizontal and never sags, even in facilities with constant daily use such as hospitals, universities, and government buildings.
ANSI Function F04: Office/Entrance Security
The ANSI F04 Office Function is designed for versatility, allowing the user to control the exterior locking status while ensuring the interior is always safe for exit.
- Toggle Locking: The exterior lever can be locked or unlocked by a toggle (rocker) switch on the face of the mortise lock or by the exterior key. When "unlocked," the door functions as a passage set for guests. When "locked," the exterior lever is rigid, and entry requires a key.
- Key Control: Even when the exterior is locked, a physical key can retract the latch for authorized entry.
- Fail-Safe Interior Egress: The interior lever is always active. Turning the inside handle retracts both the latch and the deadbolt (if applicable) simultaneously, ensuring a "single-motion" exit that is fully compliant with all life-safety and fire codes.
- Anti-Shim Protection: The auxiliary deadlatch is designed to engage when the door is closed, preventing intruders from using a tool to "loid" or shim the latch bolt open.

Professional Solutions for Modern Facility Management
The PDQ MR116 PFSF addresses the most common hardware challenges in commercial infrastructure:
- Eliminate Lever Sag: Lever drooping is a frequent maintenance headache in high-traffic hallways. The MR Series uses heavy-duty, independent spring cartridges that support the Philadelphia lever, ensuring a crisp 180-degree horizontal return for the life of the product.
- Maximum Forced Entry Resistance: Because the lock is embedded within the door itself, it utilizes the structural integrity of the door to resist physical tampering. This makes it an ideal upgrade for rooms containing sensitive data or valuable equipment.
- Retrofit Compatibility: Designed to fit standard ANSI A115.1 mortise preps, the MR116 is a drop-in replacement for aging or lower-quality mortise locks, allowing for a fast and effective security overhaul without modifying the door.
- Ergonomic Design: The PFSF (Philadelphia) lever is ADA compliant and specifically designed for ease of use. Its curved, return-to-door shape prevents clothing or equipment from snagging while providing a comfortable grip for all users.
- Vandal-Resistant Spindles: The trim is engineered with a breakaway spindle. In the event of a high-torque attack on the exterior lever, the spindle breaks cleanly to protect the internal mechanism and keep the door locked.
