Schlage L283-347 Eu Fail Secure Electric Lock Case

Product Description

The SCHLAGE L283-347 EU is an electrically unlocked, fail secure lock case designed for use in commercial door hardware applications. In a fail secure configuration, the lock remains locked when electrical power is lost, making it suitable for doors where controlled access must be maintained during a power outage. This lock case is field reversible, allowing installation on doors with either left-hand or right-hand swing without requiring a separate unit. It is typically specified and installed by licensed locksmiths, security contractors, or commercial door hardware professionals.

This lock case is intended for commercial interior and perimeter door applications where electric locking control is required. It is compatible with SCHLAGE L9090, L9092, and L9094 series mortise lock bodies. These series are commonly found in office buildings, healthcare facilities, education campuses, and government installations where access control integration is part of the door hardware specification.
