Schlage L9092EUL 03A 626 Electric Mortise Lock

Product Description

The SCHLAGE L9092EUL 03A 626 is a Grade 1 fail secure electric mortise lock designed for commercial access control applications. In a fail secure configuration, the lock remains locked when power is lost, maintaining door security during outages. The unit is supplied less cylinder, meaning the installer provides a separate cylinder to match the facility keying system. The 03 lever trim and A rose are factory-installed components that define the door hardware profile. The satin chromium plated (626) finish delivers a low-glare, corrosion-resistant surface suited to high-traffic commercial environments. Licensed locksmiths, access control technicians, and commercial door hardware installers are the primary trades for this product.

This electric mortise lock is intended for commercial interior and exterior door applications where electrified access control is required. Typical installations include office entry doors, stairwell doors, and secured access points in institutional, healthcare, education, and commercial facilities. The field-reversible handing allows the lock body to be configured for left-hand or right-hand door swing without ordering a separate unit, which reduces stocking requirements for contractors servicing mixed-swing door openings.

Key Features

• Grade 1 ANSI commercial duty rating for heavy-use door applications
• Fail secure operation - lock stays locked on power loss, supporting security-critical openings
• Supplied less cylinder - integrates with facility master key systems using a separately sourced cylinder
• Field reversible handing - configurable for left-hand or right-hand swing at the job site
• 03 lever with A rose trim included as part of the lock assembly
• Satin chromium plated 626 finish for durability and low-glare appearance in commercial settings

Compatibility

Designed as an OEM-style electrified mortise lock for commercial door applications requiring Grade 1 access control hardware with fail secure operation and standard mortise pocket preparation.

Installation Notes

Installation should be performed by a licensed locksmith or qualified access control technician familiar with ANSI mortise lock pocket dimensions and low-voltage wiring practices. Disconnect and lock out all power to the access control system before wiring or servicing the electric lock chassis. Verify door preparation - mortise pocket, backset, and face bore - matches the lock body dimensions prior to installation. All low-voltage wiring should comply with applicable NEC requirements for Class 2 circuits.
