The Accentra MO 4605LN Storeroom Lockset (formerly Yale) is a high-intent security solution engineered for commercial spaces that require permanent exterior restriction. This Series 4000 Grade 2 Standard Duty cylindrical lock is the industry standard for securing mechanical rooms, storerooms, and electrical closets where the outside lever must remain locked at all times to prevent unauthorized entry.
Featuring the clean, contemporary MO (Monroe) lever design, this hardware provides a professional look while maintaining maximum security. The Accentra 4605LN ensures the exterior lever is always rigid, requiring a key for every entry, while the interior lever remains active to ensure safe, immediate egress in compliance with life safety codes.
