Hager 3473 WTN Grade 1 Corridor Lever Lockset
Function Information:
The Hager 3473 WTN is a heavy-duty cylindrical lockset engineered for the specialized security requirements of high-occupancy buildings. Operating as a Corridor Function (ANSI F90), this hardware is the gold standard for dormitories, public housing, and institutional corridors. Featuring the classic, ergonomic Withnell (WTN) lever design, this lockset provides a perfect balance of user comfort and the Grade 1 "extra heavy-duty" performance required for million-cycle environments.
Dual-Access Security with Fail-Safe Egress
The Hager 3473 is designed for spaces that require versatile locking options. The exterior lever can be locked or unlocked via key, or locked from the interior using a push button. A critical safety feature of the Corridor Function is the automatic release: turning the inside lever or closing the door immediately releases the interior push button, preventing accidental lockouts and ensuring the door is ready for the next occupant. For life-safety compliance, the interior lever always provides free egress, allowing for an immediate exit at all times.
Institutional Resilience and Universal Accessibility
Certified to ANSI/BHMA Grade 1, the Hager 3400 Series [link] is built to withstand over one million cycles, making it the premier choice for hospitals, universities, and military housing. The Withnell lever is fully ADA compliant, offering a neutral profile that meets strict accessibility codes. To ensure a professional, vandal-resistant finish, the 3473 WTN features no exposed mounting screws and utilizes a secure thru-bolt installation for a rigid, permanent bond to the door.
