Corbin Russwin ML2057LL630 Storeroom Mortise Lock

Product Description

The CORBIN RUSSWIN ML2057LL630 is a single cylinder storeroom mortise lock designed for commercial and institutional door hardware applications. The lock features a lever-by-lever trim configuration and ships as a complete assembly including the lock body, strike, front plate, and mounting screws. The satin stainless steel finish (630) provides corrosion resistance suited to high-traffic environments. The mortise-style body integrates directly into the door edge, providing a secure, low-profile locking mechanism relied upon by commercial locksmiths and facilities maintenance teams.

This mortise lock is intended for storeroom function use, meaning the outside lever is always locked and can only be operated by key, while the inside lever provides free egress at all times. That function is common in commercial office corridors, utility rooms, server rooms, and institutional facilities where controlled entry is required but unrestricted exit must be maintained. The complete kit format reduces sourcing complexity for single-door installations or small-volume replacements.
