Corbin Russwin ML2090 Mortise Full Active Dummy Trim Non-Latching, Field Reversible, Grade 1
Commercial-Grade Mortise Dummy Trim for High-Traffic Applications
The Corbin Russwin ML2090 is a fully active dummy mortise trim from the ML2000 Series, engineered for commercial, institutional, industrial, and government environments where non-latching operation is required. Both grips remain always active, allowing the trim to function as a push or pull only without engaging a latch. Designed for 1-3/4″ (44mm) standard door thickness and featuring field-reversible handing, the ML2090 integrates seamlessly into demanding high-use settings such as offices, schools, hospitals, and hotels. Built on the Grade 1 ML2000 Series platform, it is constructed of heavy-gauge steel and backed by a 10-year limited warranty.
