Sargent 28-10XG04 LL Storeroom Function, Cylindrical Lockset
Function Information:
The Sargent 28-10XG04 LL is an elite Grade 1 Cylindrical Lock engineered for high-abuse, high-traffic environments. As part of the Sargent 10X Line, this lockset doesn't just meet industry standards—it shatters them, surviving up to 20 million cycles. The Storeroom Function (F86) ensures the outside lever is always locked, requiring a key for entry, while the inside lever always allows free egress. Featuring the freewheeling lever option, the outside handle rotates freely when locked to prevent damage from vandalism and excessive torque.
Unmatched Durability and Security
Built to protect the most demanding spaces, the 10XG04 exceeds ANSI/BHMA Grade 1 requirements for torque and pull-force by significant margins. It withstands over 3,100 in-lb of abusive torque and 1,600 lbs of offset lever pull, ensuring that even under extreme attack, the door remains secure. Its independent return springs prevent lever sag, maintaining a professional appearance and consistent performance for the life of the product.
Life Safety and Extreme Weather Compliance
The Sargent 28-10XG04 is UL/cUL listed for 3-hour fire doors and meets ADA standards with a maximum activation force of 5 pounds. It is a premier choice for coastal or high-wind regions, carrying Florida Building Code and Windstorm certifications (ASTM E330, E1886, and E1996). Whether facing daily high-frequency use in a school or the environmental stress of a hurricane, this lockset provides unwavering reliability.
