Hager 3553 AUG Grade 2 Entry Lever Lockset (Thumb Turn)
Function Information:
The Hager 3553 AUG is a heavy-duty, commercial-grade cylindrical lockset that combines the bold, linear aesthetic of the August (AUG) lever with institutional-strength security. As an Entrance Function (ANSI F109), this lock is designed for primary access points where manual control is preferred. The lock is operated by a lever from either side unless the outside is secured by the interior thumb turn or an exterior key, providing a reliable and tactile locking solution for professional environments.
Sophisticated Security and Controlled Access
The Hager 3553 is the ideal choice for office suites, conference rooms, and commercial entryways. The interior thumb turn offers a clear, manual locking state for occupants, while the exterior key cylinder ensures secure access for authorized personnel. For maximum life safety, the inside lever always allows for free egress, ensuring an immediate exit path during emergencies. To safeguard against forced entry, the deadlocking latchbolt is specifically engineered to resist "shimming" and unauthorized retraction.
Industrial Engineering 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 August lever is fully ADA compliant, providing a comfortable, modern grip that allows for easy operation without the need for tight grasping or twisting. With no exposed mounting screws and a secure thru-bolt installation, the 3553 AUG maintains a sleek profile that is highly resistant to tampering and vandalism in high-traffic areas.
