The PDQ SV116 CQ is a heavy-duty Grade 2 Office Entry Function Knob Lockset designed for professional environments that require flexible locking options and high-frequency durability. Engineered as a premier security solution for private offices, consulting rooms, and commercial entry points, this lockset provides the versatility of a push/turn button mechanism. The CQ (Ball Knob) design offers a classic, rugged aesthetic that fits comfortably in the hand while providing the structural integrity required to exceed ANSI/BHMA Grade 2 standards.

Equipped with a 2-3/4" backset and a 4-7/8" ASA strike, the SV116 is a robust retrofit solution for standard hollow metal and wood doors. Its internal mechanism features a deadlocking guarded latchbolt, which provides an extra layer of protection by preventing "loiding" or shimming attacks with credit cards or specialized tools. Whether you are managing a single office or an entire corporate suite, this lockset delivers the precision control needed to maintain privacy and security without sacrificing ease of use.

ANSI F109 Office/Entry Function: Advanced Locking Logic

The ANSI F109 Function is one of the most versatile locking configurations, offering two distinct modes of security managed from the interior button.

• Standard Push-Button Locking: When the interior button is simply pushed, the outside knob locks. It can be temporarily bypassed by a key from the outside or by turning the inside knob (egress). Once the door is opened from the inside, the button pops out, and the exterior is unlocked.
• Turn-Button "Always Locked" Mode: When the interior button is pushed and turned, the outside knob remains in a fixed, locked state. Even if the inside knob is rotated to exit, the exterior remains locked. This is the ideal solution for offices that require restricted entry throughout the workday.
• Emergency Egress: Regardless of the locking mode, the interior knob always allows for immediate, single-motion exit. This ensures full compliance with Life Safety and Fire Codes.
• Guarded Latch Security: The auxiliary deadlocking pin is depressed when the door is latched, mechanically locking the main bolt in place to thwart forced entry attempts.

Engineered Solutions for Professional Facilities

The PDQ SV116 CQ addresses the specific operational and maintenance challenges of commercial office management:

• Dual-Mode Privacy Control: The push/turn button allows users to switch between "temporary privacy" and "permanent security." This solves the problem of having to manually lock a door every time a tenant returns to their desk.
• Simplified Retrofit Installation: With the standard 4-7/8" ASA strike, this lockset fits into existing commercial metal frames without the need for grinding or drilling, making it an efficient maintenance solution for aging hardware.
• Master Key System Compatibility: Utilizing a standard Schlage C keyway, the SV116 can be integrated into complex master key hierarchies, allowing a single grand master key to access all office suites while maintaining individual tenant privacy.
• High-Traffic Reliability: The cylindrical chassis is built to withstand significantly higher cycle counts than residential hardware, reducing the total cost of ownership by extending the replacement interval in busy office corridors.
• Vandal-Resistant Chassis: The heavy-duty steel and brass internal components are designed to resist torque attacks on the exterior knob, ensuring the lock remains operational even under duress.
