The SDC Security Door Controls LR100SGK is an electric strike replacement kit designed for Sargent ELR-series electric strikes. It provides the hardware and components needed to restore or upgrade an existing Sargent ELR electric strike assembly to proper operating condition. This kit is installed by licensed locksmiths, security integrators, and access control technicians working on commercial door hardware applications. It eliminates the need to replace the full electric strike body, making it a practical service solution for maintaining access control systems in commercial and institutional facilities.
The LR100SGK is intended for use with Sargent ELR electric strike installations in commercial door frames. It is suited for retrofit and maintenance scenarios where the existing Sargent ELR strike body remains serviceable but internal or external components require replacement. Facilities maintenance teams and security hardware professionals working on hollow metal or aluminum door frames will find this kit appropriate for restoring strike function without a full hardware replacement.
Designed as a replacement kit for Sargent ELR-series electric strikes. Verify exact Sargent ELR model variant before ordering to confirm fitment.
Installation should be performed by a qualified locksmith or access control technician familiar with electric strike hardware. Disconnect power to the electric strike circuit before beginning any disassembly or component replacement. Follow the manufacturer product manual for component-specific procedures and torque guidance. Work should comply with applicable local building and life safety codes governing access control hardware.
