Hager 3573 AUG Grade 2 Corridor Lever Lockset
Function Information:

The Hager 3573 AUG is a heavy-duty, commercial-grade cylindrical lockset specifically designed for multi-family residential units, dormitories, and hotel corridors. As a Corridor Function (ANSI F90), this lockset provides the versatile security required for living spaces: the exterior lever can be locked or unlocked by an interior turn button or an exterior key. Featuring the bold, modern August (AUG) lever design, it delivers a clean, linear architectural aesthetic that fits perfectly in contemporary professional and residential environments.
Residential Security with Life-Safety Performance
The Hager 3573 is engineered to prioritize occupant safety without compromising security. While the interior turn button allows for a manual locking state, the inside lever always allows for free egress, ensuring residents can exit instantly in an emergency. The deadlocking latchbolt provides a critical barrier against forced entry, resisting common "shimming" techniques. This lockset is non-handed, making it a flexible choice for large-scale projects with varying door swings.
Industrial Engineering and Full 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 August lever is fully ADA compliant, offering an ergonomic, straight-profile grip that is easily operated by all users. To ensure a sleek finish and discourage tampering, the 3573 AUG features no exposed mounting screws and utilizes a secure thru-bolt installation for a rigid, stable attachment to the door.
