PDQ #16 Mortise Cylinder x 1-1/8" in Brushed Chrome US26D with AR Cam (I4205)
The PDQ 16 Series Mortise Cylinder is a professional-grade security component engineered for precision and durability in commercial storefront environments. This 1-1/8" cylinder is specifically tailored for narrow stile aluminum doors, featuring the industry-standard I4205 AR Cam (Adams Rite style). Finished in US26D Satin Chrome over a solid brass housing, it provides a highly resilient, corrosion-resistant solution for retail entrances, office plazas, and mixed-use commercial buildings.
Whether you are performing a security overhaul or replacing a worn unit, this cylinder offers an immediate retrofit solution for existing Adams Rite style latches and PDQ KT Series Extra Heavy-Duty Deadbolts. It features a 6-pin solid brass chamber, factory-keyed to 5 pins in the ubiquitous Schlage C (SCC) keyway, ensuring seamless integration into most commercial master key systems while providing superior physical protection against unauthorized entry.
AR Cam (I4205) Function & Application Summary
The I4205 AR Cam is the critical mechanical interface that translates the rotation of your key into the movement of the lock's internal bolt or latch.
- Storefront Integration: This specific cam profile is designed to operate the drive hubs of Adams Rite 4500, 4700, and 4900 series deadlocks and deadlatches found in aluminum storefront doors.
- PDQ KT Series Deadbolt Support: In addition to aluminum doors, this cylinder is the primary operational component for the PDQ KT Series deadbolts, providing the necessary leverage to throw a 1-inch stainless steel bolt.
- Positive Latching Solution: The precision-machined "finger" of the AR cam ensures the latch is fully retracted with a standard 90° or 360° turn, eliminating the "dead-turning" or binding often found in lower-quality universal cylinders.
- Security Deadlocking: The cam is designed to sit in a neutral position that allows the deadlock's internal trigger to engage, preventing "loiding" or shimming of the door from the exterior.

Engineered Solutions for Storefront Security
The PDQ 16 Series Cylinder addresses the most common maintenance and security challenges in the commercial sector:
- Retrofit Efficiency: The 1-1/8" length is the industry standard for most 1-3/4" thick aluminum doors. This cylinder serves as a direct replacement for failed units, allowing for a fast security refresh without modifying the door frame or lock case.
- Corrosion Resistance for Coastal Environments: The combination of a solid brass body and a Satin Chrome finish ensures that the cylinder internal pins and springs remain protected against salt air and humidity, preventing "frozen" locks on exterior-facing retail doors.
- Flexible Keying Management: By offering Keyed Different (KD) as standard, facilities can maintain individual access control for different units. For larger campuses, the ability to order cylinders in Corbin, Yale, or Sargent keyways allows for the consolidation of keys into a single master system.
- High-Traffic Reliability: Tested for heavy-duty commercial use, the precision-cut keys and tight-tolerance pins reduce mechanical wear, ensuring that high-occupancy entryways remain functional for years under constant daily use.
