Corbin Russwin ML2057LL613 Mortise Lock Oil Rubbed Bronze

Product Description

The CORBIN RUSSWIN ML2057LL613 is a single cylinder storeroom mortise lock lever set finished in oil rubbed bronze. It is a complete lock assembly that includes the lock body, strike, front plate, and mounting screws. The storeroom function means the exterior lever is always locked and can only be opened with a key, while the interior lever allows free egress at all times. This design is standard in commercial and institutional door hardware where controlled entry with unrestricted exit is required. The unit measures 4.5 inches in length by 9 inches in height by 1.5 inches in width and weighs 1.38 pounds. Licensed locksmiths and commercial door hardware specialists are the primary installers.

This mortise lock is suited for commercial and institutional applications such as offices, storerooms, server rooms, medical supply closets, and similar spaces where access control on the entry side is required without restricting egress. The storeroom function is a common specification for interior doors in healthcare, education, and government facilities. The oil rubbed bronze finish coordinates with complementary hardware on doors where a darker, traditional aesthetic is specified. The assembly ships as a single unit inclusive of all standard mounting hardware.

Installation Notes

Mortise lock installation should be performed by a licensed locksmith or qualified commercial door hardware technician familiar with mortise pocket preparation and door edge boring. Ensure the door is fully removed or held secure before mortising and that all existing hardware is removed before fitting the new lock body. Verify front plate and strike alignment with the door frame before final screw torque. Local building codes and ADA egress requirements should be confirmed prior to installation in commercial occupancies.
