Sargent 10XG04 LL Storeroom Function Cylindrical Lever Lockset — US26D Satin Chrome

The Sargent 10XG04 LL is a heavy-duty, commercial-grade cylindrical lever lockset configured for the Storeroom function — one of the most specified security functions for supply rooms, server rooms, mechanical spaces, and restricted-access areas in commercial, institutional, and government facilities. Finished in US26D (626 Satin Chrome), it delivers a professional, corrosion-resistant appearance suited to high-traffic interior openings.

Storeroom Function — What It Means for Your Opening

The Storeroom (ANSI F07) function keeps the outside lever locked at all times. Entry from the exterior requires a key on every approach — the outside lever cannot be toggled to a free-passage state. The inside lever always allows free egress, making this function fully compliant with egress requirements while maintaining tight access control. This is the correct function spec for:

• Supply closets, stockrooms, and storage areas
• Server rooms and IT equipment closets
• Mechanical and electrical rooms
• Restricted staff-only zones in schools, healthcare, and government buildings
• Any opening where continuous key control is required on the approach side

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.
