Sargent 28-65G04 KL Storeroom Function Cylindrical Lockset
Function Information:


Grade 2 Cylindrical Lockset | High-Performance Storeroom Function
The Sargent 28-65G04 (KL) is a high-security cylindrical lockset designed specifically for rooms that must remain locked at all times. The 28- prefix indicates a 4-7/8" ANSI ASA Strike.
The Storeroom Function (04) is engineered for total access control: the outside lever is always locked and cannot be left in an "unlocked" state. Entry is granted only by using a key, while the inside lever always allows for immediate, free egress. This eliminates the risk of a door being accidentally left unlocked, making it the industry standard for mechanical rooms, IT closets, and inventory storage.
Key Features
- Fail-Safe Security (04): The outside lever is permanently locked. A key is required for every entry, ensuring the space is always secure the moment the door closes.
- Hurricane & Impact Rated: Certified to meet Florida Building Code (FL# 2998) and TAS 201/202/203 standards, offering extreme resistance to forced entry and high-wind events.
- KL (L-Design) Lever: Features the clean, modern "L" trim. The non-handed design allows the lever to be reversed in the field to fit any door hand.
- Anti-Sag Thru-Bolt Mounting: Secured with heavy-duty thru-bolts that anchor the chassis directly through the door, preventing the lock from loosening or rotating under heavy use.
- Full Code Compliance: UL-cUL Fire-Rated for 3 hours and fully ADA compliant, meeting the requirements for all public and private commercial buildings.
