Sargent LC-10XG71 Lb 26D Electrified Cylindrical Lock

Product Description

The SARGENT LC-10XG71 LB 26D is a Grade 1 electrified cylindrical lock designed for access control applications in commercial door hardware systems. It operates in a fail-secure mode, meaning the latch remains locked when power is removed, making it appropriate for security-critical openings. The unit features a B lever handle, an L rose trim, and a deadlatch mechanism for positive latch retention. It ships without a cylinder installed, allowing the installer to specify the appropriate core. The satin chrome (26D) finish provides a clean, neutral appearance suited to commercial interiors. Installation is performed by licensed locksmiths or qualified commercial door hardware technicians.

This lock is intended for commercial interior or perimeter doors where electrified access control is required. Fail-secure operation makes it a common choice for stairwell doors, server rooms, and secured offices where the door must remain locked during a power loss event. The non-handed design simplifies inventory and installation, as a single unit works on doors of either hand without modification. The less-cylinder configuration supports integration with a facility's existing keying system by accepting a separately sourced cylinder.

Key Features

• Grade 1 commercial duty rating for high-cycle, high-traffic applications
• Fail-secure operation keeps latch locked when power is interrupted
• Deadlatch mechanism prevents latch from being pushed back without the lever
• Non-handed design fits left-hand or right-hand door preparation without alteration

Compatibility

Designed as an OEM-style electrified cylindrical lock replacement or new-installation unit for commercial door preparations accepting a standard cylindrical lock chassis with access control wiring provisions.

Installation Notes

Installation should be performed by a licensed locksmith or credentialed commercial door hardware technician familiar with electrified hardware and low-voltage wiring. Disconnect and lock out all power to the access control circuit before wiring or servicing the unit. Verify door preparation dimensions and strike alignment before final mounting. Local building and fire codes, including applicable provisions of NFPA 80 and IBC egress requirements, should be confirmed prior to installation on any rated or exit-path door.
