Schlage L9010 Lata 622 Mortise Lock Flat Black

Product Description

The SCHLAGE L9010 LATA 622 is a Grade 1 passage latch mortise lock designed for commercial and institutional door hardware applications. It features the Latitude lever style on an A Rose trim configuration and comes in a Flat Black Coated finish. Rated at Grade 1, this lock meets the highest ANSI/BHMA performance standards for durability and cycle life, making it suitable for high-traffic door openings. The field-reversible design allows the latch to be adapted for left-hand or right-hand door swing without special tooling, reducing installation time and simplifying inventory management for contractors and facility maintenance teams.

This mortise lock is intended for commercial interior doors where passage function is required - meaning free egress and ingress with no locking or keying. Typical applications include hallways, conference rooms, and common-area doors in office buildings, healthcare facilities, schools, and hospitality environments. The Latitude lever and A Rose trim provide a clean, contemporary profile suited to modern commercial interiors. Installation is performed by licensed locksmiths, door hardware specialists, or experienced commercial carpenters familiar with mortise lock preparation.

Installation Notes

Mortise lock installation requires a properly prepared mortise pocket in the door edge; verify door thickness and prep dimensions before ordering. A licensed locksmith or qualified commercial door hardware installer should perform the work in compliance with applicable local building codes. Power down any electrified hardware in the door frame before beginning installation. Do not force the chassis into an undersized mortise pocket, as this can damage the lock body and void the manufacturer warranty.
