Corbin Russwin ML2067 Apartment & Dormitory Mortise Lockbody, Grade 1, Field Reversible, 1-3/4" Door

Commercial-Grade Apartment & Dormitory Mortise Lock Solution for High-Traffic Applications

The Corbin Russwin ML2067 is a Grade 1 mortise lockbody from the ML2000 Series, purpose-built for apartment and dormitory applications in demanding commercial, institutional, industrial, and government environments. 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) standard door thickness and is field reversible for flexible installation. The ML2067 function allows the latchbolt to be operated by grip from either side unless the outside grip is locked by toggle-action stop or by projection of the deadbolt, with the inside grip simultaneously retracting both the latchbolt and deadbolt while the outside grip remains locked. Backed by a 10-year limited warranty and UL cycle tested to over 14.5 million cycles, the ML2067 delivers life safety and security in a single door preparation.
