PDQ 639709 Standard Rim Strike for 6300R & 6300RF Rim Exit Devices

The PDQ 639709 Standard Rim Strike is a high-performance, heavy-duty architectural strike engineered specifically for the PDQ 6200R and 6300R Series Rim Exit Devices. As a critical security solution, this strike serves as the essential latching point for the panic bar’s Pullman-style bolt, ensuring the door remains firmly locked against external force while facilitating immediate, single-motion egress. Manufactured from investment cast stainless steel, the 639709 is built to withstand the high-impact cycles typical of heavy-commercial and institutional environments such as schools, hospitals, and industrial facilities.

Designed for maximum versatility, this strike is fully compatible with both Non-Fire Rated Panic Hardware and 3-Hour Fire-Rated Exit Devices. Whether you are securing a standard storefront or a critical fire-stairwell door, the 639709 Rim Strike provides a precision-contoured ramp that reduces friction during the latching cycle. This anti-friction design prevents "door bounce" and ensures the exit device stays positively latched, even in buildings prone to air pressure fluctuations or minor frame misalignment.

Rim Strike Function & Security Summary

The Standard Rim Strike is the "stationary" foundation of the locking mechanism for surface-mounted exit hardware. Its mechanical integrity is vital to the security of the building envelope:

• Positive Latching Control: The 639709 provides a deep, secure engagement pocket for the latchbolt. This prevents the door from being pushed or pulled open without the exit device being activated from the interior.
• Fire-Rated Performance: On fire doors, this strike ensures the door remains "positively latched" during high-heat events, maintaining the integrity of the fire barrier and preventing the passage of smoke and flames.
• Anti-Friction Egress: The lead-in ramp is engineered for a smooth transition, allowing the latchbolt to retract effortlessly when the push bar is depressed, satisfying all Life Safety and ADA emergency exit requirements.
• Vandal Resistance: Constructed from high-grade stainless steel, this strike resists prying, filing, and physical tampering, providing a formidable barrier at the most vulnerable point of the door opening.

Technical Specifications

Engineered Solutions for High-Traffic Infrastructure

The PDQ 639709 addresses specific technical challenges in commercial hardware maintenance:

• Eliminate Latch Binding: Over time, doors can sag or frames can settle. The 639709 strike features a generous engagement area that allows for minor door movement without causing the latch to bind or stick, significantly reducing maintenance service calls.
• Hardware Lifecycle Extension: By providing a smooth, anti-friction surface for the panic bar's latchbolt, this strike reduces the mechanical stress on the exit device's internal springs and chassis, effectively extending the lifespan of the entire 6300 Series unit.
• Corrosion Protection: The stainless steel construction makes this the ideal security solution for exterior doors or coastal facilities. Unlike plated steel strikes, the 639709 will not rust or degrade when exposed to moisture and salt air.
• Simplified Retrofitting: Designed to match the factory footprint of PDQ 6200/6300 hardware, this strike can be replaced in minutes using existing prep, making it a "quick-fix" for damaged strikes in high-traffic hallways.
• Safe Egress Compliance: This strike is a key component in ensuring the door meets Life Safety codes, providing a reliable and predictable release every time the exit device is used during an emergency.
