PDQ 4SH09 PHL Heavy Duty Storeroom Exit Device Trim - Philadelphia Lever ANSI 09

The PDQ 4SH09 PHL (legacy model 429 LPSH) is a premium, extra heavy-duty lever trim designed for high-traffic commercial environments that require the highest level of security and architectural appeal. Featuring the sleek, modern Philadelphia (PHL) lever design, this trim provides an ergonomic and ADA-compliant solution for school corridors, hospital wings, and corporate office exits. As a part of the 4200 Series hardware line, the 4SH09 is engineered to withstand the rigors of constant daily use while maintaining its structural integrity and aesthetic finish.

This trim is a premier "problem-solver" for door retrofits. It is specifically engineered to cover a standard 2-1/8" (161) cylindrical lock prep, allowing facility managers to upgrade a standard bored-hole door to a high-security exit device system without the cost of door replacement or patching. The heavy-duty through-bolt mounting creates a rigid "sandwich" effect with the interior panic bar, ensuring the lever remains securely anchored even in high-abuse settings.

ANSI Function 09: Storeroom/Night Latch Security

The ANSI 09 Function is defined by its "always-locked" exterior state, providing a secure perimeter that requires a key for every entry.

• Constant Exterior Lock: The exterior Philadelphia lever is always rigid and locked. It does not rotate to retract the latch unless a key is inserted and turned.
• Key-Retracting Operation: Entry is granted only when the key is used to retract the latch bolt. Once the key is removed, the lever immediately returns to its locked state.
• Key-Retaining Logic: To prevent security lapses, the key is only removable when the device is in the locked position. This ensures that authorized personnel cannot accidentally leave the door in an "unlocked" state.
• Life Safety Egress: Regardless of the exterior lever status, the interior exit device always allows for immediate, uninhibited egress, maintaining full compliance with National Fire Protection Association (NFPA) codes.

Professional Solutions for Facility Management

The PDQ 4SH Series addresses the most common failures found in commercial door hardware:

• Anti-Sag Technology: One of the most common issues with exit device trims is lever drooping. The 4SH09 features a heavy-duty independent spring cage that supports the lever, ensuring the Philadelphia design stays perfectly horizontal even after hundreds of thousands of cycles.
• Seamless Retrofitting: By covering the existing 2-1/8" hole from a previous cylindrical lock, this trim saves hours of labor. It allows for a clean, professional-looking upgrade that hides old mounting scars and finish transitions.
• ADA & Accessibility Compliance: The PHL lever’s return-to-door design meets all ADA requirements, preventing fire hoses or clothing from catching on the lever while ensuring ease of use for individuals with limited hand strength.
• Electronic Access Ready: This is the ideal mechanical trim for use with electric strikes. The "always locked" exterior ensures that the electronic access control system remains the primary gatekeeper, while the mechanical key provides a reliable emergency bypass.
• Buy American Act (BAA): Assembled in the USA, this hardware satisfies the rigorous procurement requirements for federal, state, and municipal government projects.
