The Harloff Replacement Lock Kit for Narcotics Cabinets provides a comprehensive security restoration package engineered for dual-door and double-lock controlled substance storage units. Designed to maintain strict DEA compliance and pharmacy security protocols, each kit includes two high-security tubular cam locks along with four new keys per lock, allowing facility personnel to completely re-key dual-lock narcotics cabinets in a single service event. Available in both 3/8-inch and 7/8-inch barrel length variations, these kits accommodate specific cabinet wall and door thickness profiles across the Harloff 2700 and 2800 series lineup. Constructed with heavy-duty tubular keyways that resist picking and physical tampering, these OEM replacement kits enable facility engineers to rapidly resolve lost key scenarios, restore compromised cylinders, and ensure continuous high-level security for Schedule II-V controlled substances across hospital wards, surgical suites, and pharmacy vaults.
