The Accentra AU 4705LN Storeroom Lockset (formerly Yale) is a high-intent, heavy-duty security solution engineered for maximum protection in commercial environments. As a flagship model in the Series 4700LN Grade 1 lineup, this cylindrical lock is the industry standard for mechanical rooms, electrical closets, and high-security storage areas where the exterior must remain locked at all times to safeguard critical assets.
Featuring the contemporary and ergonomic AU (Augusta) lever design, this lockset is built with the advanced Free Wheeling lever mechanism. This high-performance feature allows the outside lever to rotate freely when locked, significantly reducing the risk of damage caused by vandalism or excessive torque, ensuring long-term operational integrity in the most demanding high-traffic facilities.
Maximum Security & Industrial Performance
- Storeroom Security (ANSI F86): The exterior lever is always rigid and requires a key for entry. The interior lever is always active, providing a constant, unobstructed path for emergency egress.
- Free Wheeling Lever: Designed to withstand abuse; when the lock is engaged, the outside handle moves without retracting the latch, protecting internal components from forced entry attempts.
- Grade 1 Industrial Strength: Certified ANSI/BHMA A156.2, Series 4000, Grade 1, offering the highest structural integrity and cycle life available for commercial hardware.
- Fire-Rated Safety: UL-cUL listed for all fire doors with a rating up to 3 hours, essential for maintaining building code compliance in utility and exit pathways.
- Deadlocking Latchbolt: Features a 1/2" throw deadlocking latchbolt that provides essential resistance against "shimming" and unauthorized tampering.
- ADA & Accessibility: Fully compliant with ADA A117.1 Accessibility Codes, ensuring the lever is easy to operate for authorized personnel.
