Corbin Russwin ML2032 Grade 1 LL Institution or Utility - Mortise Body Only

Corbin Russwin ML2032-LL Institution/Utility Mortise Lock Body - ANSI F30, Grade 1, Field Reversible

Commercial-Grade Institution and Utility Mortise Lockbody for High-Traffic Applications

The Corbin Russwin ML2032-LL is a Grade 1 mortise lock body from the ML2000 Series, engineered for institution and utility applications in demanding commercial, institutional, industrial, and government environments. Conforming to ANSI function F30, this lockbody operates with latchbolt control by key from either side while both grips remain always rigid, and features an auxiliary latch that deadlocks the latchbolt for enhanced security. Designed for 1-3/4" (44mm) standard door thickness with a field-reversible handing, the ML2032-LL ships with an ANSI straight lip standard strike measuring 4-7/8" (124mm) x 1-1/4" (32mm) x 1-1/8" (29mm) lip to center. Constructed of heavy-gauge steel with a 1" stainless steel deadbolt and patented Quick Reversible latchbolt, this lockbody delivers the reliability and versatility required for offices, schools, hospitals, hotels, and other high-use facilities. Important Safety Note: ANSI function F30 does not allow free egress and can pose a life safety hazard in the event of an emergency. Installation should be in accordance with approved codes only.
