Corbin Russwin ML2065 Grade 1 Mortise Dormitory or Entrance Lockset

Corbin Russwin ML2065-KEYED Grade 1 Mortise Dormitory/Entrance Lock with Deadbolt, Field Reversible

Commercial-Grade Dormitory and Entrance Security with Integrated Deadbolt Protection

The Corbin Russwin ML2065-KEYED is a Grade 1 mortise dormitory/entrance lockset from the ML2000 Series, engineered for high-traffic commercial, institutional, industrial, and government applications. Designed for 1-3/4" (44mm) standard door thickness, this lockset features a patented Quick Reversible latchbolt and a 1" stainless steel deadbolt in a heavy-gauge steel lockbody. The latchbolt operates freely by grip from either side unless the outside grip is locked by projection of the deadbolt, while the deadbolt is thrown or retracted by key from outside or by thumbturn from inside. The inside grip simultaneously retracts both the latchbolt and deadbolt and unlocks the outside grip, with the inside grip always remaining free for safe egress.
