PDQ 4SH08 PHL Heavy Duty Classroom Exit Device Trim - Philadelphia Lever ANSI 08

The PDQ 4SH08 PHL (legacy model 429 LPSH) is an architectural-grade extra heavy-duty lever trim specifically engineered for educational facilities, healthcare institutions, and corporate campuses. Featuring the refined, modern Philadelphia (PHL) lever design, this trim offers an ergonomic, ADA-compliant solution for high-traffic egress points. As a core component of the 4200 Series hardware ecosystem, the 4SH08 is built to withstand the rigorous "push-pull" cycles of a busy school day while maintaining its precision-aligned horizontal profile.

This trim serves as a primary solution for professional door retrofitting. It is uniquely designed to cover a standard 2-1/8" (161) lock prep, allowing facility managers to convert a standard bored-hole door into a high-security panic exit system without the labor-intensive process of patching or replacing the door leaf. The robust through-bolt mounting system creates a high-strength "sandwich" with the interior exit device, providing superior resistance to prying, pulling, and vibrational loosening.

ANSI Function 08: Classroom Security and Flexibility

The ANSI 08 Function is the gold standard for educational and municipal environments, offering a versatile balance between open access and restricted security.

• Key-Controlled Access: The exterior Philadelphia lever can be toggled between a "locked" and "unlocked" state using a physical key.
• Classroom Logic: When the lever is locked, the door remains securely latched from the outside, requiring a key for every entry. When the lever is unlocked by an authorized key holder, it functions as a "passage" handle, allowing free entry for students or staff without a key.
• Positive Self-Latching: Regardless of whether the lever is in the locked or unlocked state, the door will always self-latch when closed. This ensures the door remains a closed barrier for fire safety and environmental control.
• Fail-Safe Egress: The interior exit device always allows for immediate, uninhibited emergency egress. The exterior locking state never affects the ability of occupants to exit the building in a single motion.

Technical Specifications

Engineered Solutions for High-Abuse Environments

The PDQ 4SH Series is purpose-built to eliminate the most common maintenance headaches associated with commercial door hardware:

• Heavy-Duty Spring Support: To combat "lever sag"—a frequent failure in lower-grade hardware—the 4SH08 features an independent, heavy-duty spring cage. This ensures the Philadelphia lever returns to a perfectly horizontal position even after years of high-frequency use.
• Labor-Saving Retrofit: Upgrading an existing office door to an exit device often leaves an unsightly 2-1/8" hole. This trim’s oversized rose design completely masks the old lock prep, providing a clean, factory-fresh appearance for any restoration project.
• ADA & Life Safety Compliance: The PHL lever’s return-to-door design prevents fire hoses, equipment, or clothing from snagging on the hardware during an emergency, while satisfying all ADA requirements for accessibility and ease of operation.
• Master Key Integration: Shipped with a standard Schlage C cylinder, this hardware can be seamlessly integrated into your facility's existing master key system, allowing for simplified key management across various door types.
• Buy American Act (BAA): Assembled in the USA, this hardware meets the domestic sourcing requirements for federal, state, and municipal government-funded projects.
