Schlage L9010 Lata 643E Mortise Lock Aged Bronze

Product Description

The SCHLAGE L9010 LATA 643E is a Grade 1 commercial-grade passage latch mortise lock featuring the Latitude lever design on an A Rose trim. Built for heavy-duty door applications where locking is not required, the passage function allows free passage from both sides at all times. The Aged Bronze (643E) finish provides a distinctive appearance suited to commercial and institutional interiors. Field reversible for handing, this lock can be adapted to left- or right-hand door swings without returning to the supplier or ordering a separate unit.

This mortise lock is designed for commercial and institutional applications such as office corridors, hallways, conference rooms, and interior doors where controlled access is not needed. The Latitude lever is a clean, contemporary lever profile commonly specified in healthcare, education, hospitality, and municipal facilities. Installation is performed by licensed locksmiths or commercial door hardware professionals working to project specifications and applicable building codes.

Installation Notes

Installation should be performed by a qualified locksmith or commercial door hardware technician familiar with mortise lock prep dimensions and ANSI standards. Verify door thickness, backset, and mortise pocket dimensions before installation. Confirm handing in the field prior to final mounting, as the lock is field reversible but should be set before the trim is fully secured. Follow all applicable local building and fire egress codes when specifying passage-function hardware for rated door assemblies.
