Schlage L9010 03B 622 Passage Latch Mortise Lock

Product Description

The SCHLAGE L9010 03B 622 is a Grade 1 passage latch mortise lock designed for commercial door hardware applications. It features the 03 lever style paired with a B rose trim, finished in a flat black coated (622) surface treatment. Passage function means the latch retracts freely from either side without a key or turn piece, making it suited for corridors, hallways, and interior passageways that require unrestricted traffic flow. The lock is field reversible, allowing the hardware to be adapted for both left-hand and right-hand door swings without additional parts. Licensed locksmiths, commercial door hardware installers, and general contractors typically handle installation.

This mortise lock is intended for commercial and institutional interior doors where Grade 1 heavy-duty performance is required. Typical applications include office corridors, healthcare facilities, educational buildings, and hospitality interiors where a passage function is appropriate. The flat black coated finish coordinates with modern and industrial design specifications. Field reversibility simplifies installation on job sites where door hand is confirmed at the time of fitting rather than at the time of ordering.

Installation Notes

Mortise lock installation requires cutting a precise mortise pocket into the door edge and should be performed by a licensed locksmith or qualified commercial door hardware installer. Confirm door hand and handing of the lock body before cutting. Follow ANSI A156.13 standard door prep dimensions and verify that the door thickness and backset match the specified lock chassis. Always de-energize any access control or electrified hardware integrated with the door system before beginning work.
