Hager 3579 WTN Grade 2 Keyed Communicating Lever Lockset
Function Information:
The Hager 3579 WTN is a specialized, commercial-grade cylindrical lockset designed for interconnected rooms where access must be strictly controlled from one side only. As a Communicating Function (ANSI F80), this hardware features a keyed lever on one side and a solid blank plate on the other. This configuration is the industry standard for hotel "connecting" rooms, laboratory ante-rooms, and executive suites where a door should only be operable from one direction. Featuring the timeless, ergonomic Withnell (WTN) lever, it provides a neutral architectural profile suitable for any professional environment.
Specialized Security and Controlled Access
The Hager 3579 is engineered for maximum versatility in restricted-access applications. With a solid blank plate on the exterior (or interior, depending on installation), there is no hardware to manipulate from that side, effectively sealing the passage. The opposite side features a keyed lever that is locked or unlocked via an exterior key. This function is critical for maintaining privacy and security between two separate living or working spaces. To protect against unauthorized entry, the deadlocking latchbolt is designed to resist "shimming" and forced retraction when the door is closed.
Institutional Build and Universal Accessibility
Certified to ANSI/BHMA Grade 2 standards, the Hager 3500 Series features a heavy-gauge steel chassis with a zinc dichromate finish for superior corrosion resistance. The Withnell lever is fully ADA compliant, providing a comfortable grip that is easily operated without the need for tight grasping or twisting. To ensure a professional finish and discourage tampering, the 3579 WTN features no exposed mounting screws and utilizes a secure thru-bolt installation for a rigid, stable attachment to the door.
