Sargent 28-7G04 LL Storeroom Function, Cylindrical Lockset
Function Information:
The Sargent 28-7G04 LL is an industrial-grade Grade 2 Cylindrical Storeroom Lock engineered for high-security applications in commercial, medical, and government facilities. As a key component of the Sargent 7-Line Series, this lockset is designed for openings that must remain permanently locked to unauthorized traffic while allowing effortless egress from the interior. The 28-prefix specifies the inclusion of the 808 Curved Lip ANSI Strike, while the LL design features a sleek, linear lever made of solid one-piece cast construction for a premium, precise action.
Maximum Security for Restricted Areas
The 04 Storeroom Function (ANSI F86) is the industry standard for mechanical rooms, janitorial closets, and IT suites where security cannot be left to chance.
- Always Locked Exterior: The outside lever is always rigid. Entrance is only possible by using a physical key to retract the latchbolt, ensuring the room is never accidentally left unlocked.
- Instant Interior Egress: The inside lever is always free for immediate exit. This ensures 100% compliance with NFPA 101 Life Safety codes and ADA accessibility requirements.
- Deadlocking Protection: Features a 1/2" throw stainless steel latch with a deadlocking auxiliary bolt to prevent "shimming" or unauthorized manipulation of the latch when the door is closed.
- Solid Cast Construction: Unlike stamped or hollow alternatives, the LL levers are solid, one-piece castings that provide a substantial feel and superior resistance to wear and abuse.
Institutional Strength and Rapid Installation
The Sargent 7-Line is built to outperform the baseline for Grade 2 hardware, offering facility managers "heavy-duty" performance in a versatile, standard-duty footprint.
- Exceeds Industry Standards: This series significantly exceeds ANSI/BHMA A156.2 Grade 2 cycle requirements, providing a long service life with no maintenance required.
- One-Minute Installation: Specifically engineered for maximum efficiency, the 7G04 installs in one minute or less, drastically reducing labor costs for facility-wide upgrades.
- Through-Bolted Stability: Internal through-bolts supply unmatched strength and stability without requiring additional door preparation, fitting standard modified 161 door preps.
- Corrosion Resistance: The cylindrical housing is constructed of steel with a zinc dichromate finish to protect the internal mechanism from environmental wear.
