About this item

The Corbin Russwin ML2053 is the entrance and office function mortise lock from the ML2000 Series, one of the most widely specified Corbin Russwin mortise locksets in commercial construction. If you're a facilities manager, locksmith, or architect who's ever worked on an institutional or government door schedule, you've seen this lock. It's the Grade 1 commercial mortise lock that shows up in schools, hospitals, office buildings, hotels, and government facilities because it's built to take constant abuse and keep performing.

 

How the Entrance/Office Function Works

 

The ML2053 operates on ANSI Function F05. From either side, the latch retracts freely with the grip unless the outside grip has been locked. The outside grip is locked or unlocked by key or thumbturn, depending on the trim configuration you specify. When the outside grip is locked, a key still retracts the latch from outside for authorized entry. The auxiliary latch deadlocks the main latchbolt automatically when the door closes, which prevents the latch from being slipped or defeated with a tool. The inside grip is always free, which is the correct behavior for egress on any occupied commercial door.

 

This is the function for a main entrance or private office where staff or tenants need key control from outside with unrestricted exit from inside at all times.

 

ML2000 Series Construction

 

The lockcase is heavy-gauge steel, 5-7/8" x 4" x 15/16" (149mm x 102mm x 24mm). The armored front is heavy-gauge steel at 8" x 1-1/4" with a wrought brass, bronze, or stainless steel finish plate attached by machine screws. The latchbolt is a 2-piece mechanical design with anti-friction insert, 5/8" x 1" x 3/4" throw. The deadbolt is one-piece stainless steel at 19/32" x 1-1/4" x 1" throw. The auxiliary latchbolt has a 9/16" effective throw with 3/8" deadlocking. That's a full security assembly in a single door prep, eliminating the need for a separate deadlock on the same door and saving installation cost on every opening.

 

The lock is tested well beyond the Grade 1 requirement. Corbin Russwin completed UL cycle testing at 14.5 million cycles on the ML2000 Series. Grade 1 requires 250,000. That's not marketing copy, that's a third-party verified result.

 

Quick Reversible Handing

 

The ML2053 is handed, but uses Corbin Russwin's patented Quick Reversible feature. You can re-hand the lock without disassembling the lockcase. On a mixed handing door schedule, this saves real time during installation and allows field corrections without sending product back. Backset is 2-3/4" (70mm). Standard door thickness is 1-3/4" (44mm) with optional thicknesses available.

 

Cylinder and Trim Options

 

The ML2053 accepts Corbin Russwin cylinders and is also compatible with most other manufacturers' mortise cylinders. Available in standard, Large Format IC core (CL6 suffix), and Less Cylinder (LC suffix) configurations. Trim styles include NSA, PSA, LSA, NSM, and others depending on lever profile. Available finishes include 626 Satin Chrome, 630 Satin Stainless, 605 Bright Brass, 606 Satin Brass, 612 Satin Bronze, 613 Oil Rubbed Bronze, 619 Satin Nickel, and 625 Bright Chrome.

 

The ML2053 accommodates both flat doors and doors beveled 1/8" in 2". Strike is wrought brass, bronze, or stainless steel, ANSI straight lip standard at 4-7/8" x 1-1/4". The ML2000 Series carries a 10-year warranty.
