The Accentra CA 4605YC Storeroom Knob Lockset (formerly Yale) is a high-security, standard-duty cylindrical lock engineered for areas requiring constant restricted access. This ANSI/BHMA Grade 2 certified lockset is the industry standard for storerooms, mechanical closets, and utility rooms where the exterior must remain locked at all times. Built by ASSA ABLOY Accentra, it combines robust mechanical engineering with a budget-friendly price point for commercial and institutional projects.
Featuring the classic California (CA) ball knob, this lockset is designed for maximum security. The F86 Storeroom Function ensures that the outside knob is always rigid and can only be operated by a key, while the inside knob is always active to allow for immediate, single-motion egress. With a UL/cUL 3-hour fire rating, it provides essential life safety protection for any commercial facility.
High-Security Commercial Features
- Storeroom Function (ANSI F86): The outside knob remains fixed and rigid. Access is granted only via key, ensuring the door is always locked from the outside even if it is closed behind you.
- Deadlocking Latchbolt: Features a guarded deadlatch that prevents "shimming" or "loiding" attacks, providing a higher level of security than standard passage or privacy latches.
- Grade 2 Performance: Certified to ANSI/BHMA A156.2 Series 4000 standards, providing reliable operation and long-lasting durability in medium-traffic environments.
- Flexible Cylinder Options: Compatible with 6-pin conventional cores or Small Format Interchangeable Cores (SFIC), allowing for easy integration into existing master key systems.
- Heavy-Duty ANSI Strike: Includes a 4-7/8" x 1-1/4" ASA strike (ANSI A115.2), which is the standard for commercial steel frames.
- Fire Safety Compliance: Fully UL-cUL listed for 3-hour fire doors and NFPA 80 compliant, ensuring your building stays up to code.
