Commercial-Grade Mortise Security for High-Traffic Entrances and Storerooms

The Corbin Russwin ML2024-KEYED is a Grade 1 mortise entrance and storeroom lockset from the ML2000 Series, engineered for demanding commercial, institutional, industrial, and government applications. Conforming to ANSI function F21, this lock features latchbolt operation by grip from either side when the deadbolt is retracted, deadbolt operation by key outside or thumbturn grip inside, and latchbolt retraction by key outside — with non-panic release and no simultaneous deadbolt and latch retraction.

The ML2000 Series has achieved UL Cycle testing above and beyond requirements, verified at 14.5 million cycles (Verification ID: V875753), making it an exceptional choice for offices, schools, hospitals, hotels, and other high-use environments.
