Corbin Russwin ML2062 Grade 1 Mortise Intruder Deadbolt Lever Lockset

Corbin Russwin ML2062-KEYED Mortise Intruder Deadbolt Lever Lockset Grade 1, Field Reversible, 1-3/4" Door

Commercial-Grade Intruder Deadbolt Mortise Lock for High-Traffic Security Applications

The Corbin Russwin ML2062-KEYED is a Grade 1 mortise intruder deadbolt lever lockset from the ML2000 Series, engineered for demanding commercial, institutional, industrial, and government environments. Constructed of heavy-gauge steel with a 1" stainless steel deadbolt and patented Quick Reversible latchbolt, this lockset is designed for 1-3/4" (44mm) standard door thickness and features field-reversible handing for flexible installation. The ANSI F33 function allows the latchbolt to operate by grip from either side unless the outside grip is locked by projection of the deadbolt, while the inside grip simultaneously retracts both the latchbolt and deadbolt and unlocks the outside grip. The included ANSI straight lip strike measures 4-7/8" (124mm) x 1-1/4" (32mm) x 1-1/8" (29mm) lip to center, ensuring a precise and secure fit.
