Corbin Russwin ML2065 Grade 1 Dormitory or Entrance - Mortise Lockbody Only

Corbin Russwin ML2065 Dormitory/Entrance Mortise Lockbody, Grade 1, Field Reversible, 1-3/4" Door

Commercial-Grade Dormitory/Entrance Mortise Lock for High-Traffic Applications

The Corbin Russwin ML2065 is a Grade 1 mortise lockbody from the ML2000 Series, engineered for dormitory and entrance applications in demanding commercial, institutional, industrial, and government environments. The latchbolt operates 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 grip from inside; the inside grip simultaneously retracts both the latchbolt and deadbolt and unlocks the outside grip, with the inside grip always remaining free. Designed for 1-3/4" (44mm) standard door thickness with a field-reversible handing feature, this lockbody is constructed of heavy-gauge steel and includes a patented Quick Reversible latchbolt and a 1" stainless steel deadbolt. The ML2065 has been UL cycle tested above and beyond requirements, completing 14.5 Million Cycles (Verification ID: V875753), and carries a 10 Year Limited warranty.
