PDQ I5306 SFIC 6 Pin Mortise Cylinder Housing - 1-1/4" US26D (Less Core)
The PDQ I5306 SFIC Mortise Cylinder is a high-performance architectural housing engineered for seamless integration with Small Format Interchangeable Core (SFIC) systems. This 1-1/4" length cylinder is a versatile security solution for commercial and institutional doors, allowing facility managers to implement a rapid re-keying strategy without removing the lockset from the door. Finished in US26D Satin Chrome, the housing provides a durable, professional aesthetic that matches modern hardware while offering the structural integrity required for high-traffic environments like schools, hospitals, and office complexes.
Designed as a "less core" unit, the I5306 acts as the universal vessel for any standard 6-pin SFIC core (including Best, Falcon, and Arrow compatibles). Its multi-cam compatibility makes it a "problem-solver" for maintenance departments, as it can be field-configured with specialized cams to operate almost any major brand of mortise lock. By utilizing this SFIC housing, facilities can significantly reduce locksmith labor costs and downtime, enabling security personnel to restore safety in seconds after a key is lost or stolen.
Universal Cam Compatibility & Functional Solutions
The PDQ I5306 is uniquely versatile due to its support for multiple interchangeable cams. This allows one cylinder body to solve diverse hardware challenges across a facility:
- PDQ MR Series (I54061): The Cloverleaf Cam is specifically timed for the PDQ MR Series Grade 1 Mortise Lock, ensuring precise retraction of the 11-million cycle rated mechanism.
- Adams Rite Storefronts (I54011): The AR Cam enables this SFIC housing to operate narrow-stile aluminum doors, a common requirement for retail and commercial entries.
- Schlage & Sargent Retrofits: Specialized cams allow the I5306 to integrate into existing Schlage (I54051 Cam) or Sargent (I54041 Cam) mortise locksets, maintaining architectural consistency while upgrading to an SFIC key system.
- Legacy Hardware Support: The Wide Straight Cam (I54031) provides a vital solution for maintaining Old Yale Mortise Locks, extending the life of older infrastructure without requiring a full lockset replacement.

Engineered Solutions for Facility Management
The PDQ I5306 SFIC Housing addresses critical pain points for modern building administrators:
- Rapid Re-Keying Efficiency: The SFIC design allows for "one-second re-keying." By using a Control Key to swap the core, you eliminate the need to wait for a locksmith, ensuring the building is secured immediately during employee turnover or security breaches.
- Corrosion-Resistant Durability: Constructed from solid brass with a Satin Chrome finish, the I5306 is built to withstand the elements on exterior doors and the harsh chemicals used in healthcare sanitation protocols.
- Standardized Infrastructure: By standardizing on the 1-1/4" I5306 housing, a facility can use a single cylinder model across different lock brands (Schlage, Yale, etc.) simply by swapping the cam. This reduces inventory overhead and simplifies maintenance training.
- High-Security Readiness: While sold "less core," this housing is compatible with high-security and restricted SFIC cores, providing a pathway to upgrade a building’s physical security without replacing the underlying mortise hardware.
- Life Safety Compliance: When paired with appropriate cams, this cylinder ensures the positive operation of fire-rated exit devices and mortise locks, maintaining the integrity of the building’s egress path and fire barriers.
