Description
The Schlage L9056B LONB 643E is an extra heavy-duty mortise lock engineered for high-traffic commercial environments like schools, hospitals, and factories. Built to ANSI Grade 1 standards, it resists constant use and abuse with a fully wrapped steel case, zinc-plated components, and anti-friction tongue design that reduces wear.
This universal lock case accommodates ten functions and field-reversible handing without opening the case. It features a break-away spindle for security and easy replacement, hub blocking plate to discourage spindle manipulation, and fail-secure operation via spring-loaded fusible link.
