Corbin Russwin ML2029-LL Hotel/Motel Mortise Lockbody Only - Grade 1, ANSI F15, Field Reversible

Commercial-Grade Hotel & Motel Mortise Lock Solution for High-Traffic Applications

The Corbin Russwin ML2029-LL is a Grade 1 mortise lockbody engineered for hotel and motel applications within the trusted ML2000 Series. Conforming to ANSI function F15, this lockbody allows the latchbolt to be operated by grip inside and by guest key or master key outside, while the deadbolt is controlled by thumbturn grip inside or by emergency key outside — with the emergency key capable of shutting out all other keys. Constructed of heavy-gauge steel with a 1" stainless steel deadbolt and patented Quick Reversible latchbolt, this lockbody is designed for 1-3/4" (44mm) door thickness and is field reversible for flexible installation. The ML2000 Series has been UL cycle tested above and beyond requirements, completing 14.5 Million Cycles (Verification ID: V875753), making it an ideal choice for demanding commercial, institutional, industrial, and government environments.
