Corbin Russwin ML2053-NSA-626-M31 – Frequently Asked Questions

1) Does the Corbin Russwin ML2053 lever trim include the mortise lock body, or is it trim only?
Trim only. The ML2053 is the lever trim component for the ML2000 Series mortise lockset, so it covers the levers, rose or escutcheon and mounting hardware. The mortise case itself, the cylinder and the strike are separate. If you are replacing a damaged lever or changing the trim design on an existing ML2000 opening, this is the right part. If the opening has no mortise lock in it yet, you need a complete ML2000 Series lockset as well.
2) Will this Corbin Russwin mortise trim work on a left hand door and a right hand door?
Handing is field reversible, so one part covers both. The ML2000 Series uses a patented quick reversible latchbolt that re-hands without pulling the lock case apart, and the trim follows. The one exception to keep in mind is the Dirke lever, which is ordered specifically as left hand or right hand.
3) What door thickness and backset does the Corbin Russwin ML2000 mortise lock work with?
Standard build is 1-3/4 inch (44mm) door thickness with a 2-3/4 inch (70mm) backset, which is the normal commercial prep. Optional thicknesses are available from the factory if your doors run heavier. The lock case itself measures 5-7/8 x 4 x 15/16 inches, so the door pocket has to be cut to that.
4) Will the ML2000 mortise lock latch into my existing ANSI strike?
It is built around an ANSI straight lip strike measuring 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center. The latchbolt throws 3/4 inch (19mm) and the deadbolt throws a full 1 inch, with a 9/16 inch effective throw auxiliary latch that deadlocks the main bolt. If your frame already carries a standard ANSI 4-7/8 inch strike prep with that lip-to-center, it drops in; a shallower lip or a non-ANSI cutout means replacing the strike.
5) Do I have to use Corbin Russwin cylinders with this mortise lock, or can I keep my existing keyway?
The ML2000 Series works with new or existing Corbin Russwin key systems and also accepts most other manufacturers' cylinders, so an existing master key system can usually carry over. The standard cylinder shipped is brass, 6-pin L4 keyway, 0-bitted. Lever-to-cylinder spacing is 3-5/8 inches center to center, and lever to thumbturn is 2-7/16 inches, which is what determines whether an escutcheon trim lines up with the cylinder hole.
6) Is the Corbin Russwin ML2000 mortise lock approved for a fire rated door?
Yes. It is UL/cUL listed and UL10C positive pressure rated, good for a 3-hour fire door up to 4 by 10 feet single or 8 by 10 feet pair. It also meets ANSI/BHMA A156.13 Series 1000 Grade 1 for both operational and security, and ADA A117.1, plus California State Fire Marshal and windstorm/hurricane certification.
7) What do I have to specify when ordering ML2053 lever trim?
Three choices decide the part. Lever design: Armstrong, Citation, Dirke (left or right hand), Essex, Lustra cast or wrought, Newport, Princeton or Regis. Rose or escutcheon: A rose at 2-1/4 inch diameter, F rose at 2-7/8 inch diameter, M escutcheon or N escutcheon. And finish, from 605 bright brass through 606, 611, 612, 613, 613E, 618, 619, 625, 626, 629, 630 satin stainless, 722 black oxidized bronze oil-rubbed and BSP black suede powder coat.
8) What door function is the ML2053 mortise lockset trim used for?
Entrance/Office function. In practice that means the outside lever is locked or unlocked by key or by a turn, and the inside lever always retracts the latch for free egress. It suits tenant suite doors, private offices and staff rooms in commercial, institutional, industrial and government buildings.
9) I need to match existing door hardware in my building. What finishes does the Corbin Russwin ML2053 lever trim come in?
Fourteen finishes, covering the usual commercial matches: 626 satin chrome and 630 satin stainless steel for most office and institutional work, 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 and 613E oil-rubbed and dark oxidized bronze, 618 bright nickel, 619 satin nickel, 625 bright chrome, 629 bright stainless, 722 black oxidized bronze oil-rubbed, and BSP black suede powder coat. Those are BHMA finish numbers, so they cross-reference directly against the finish codes already on your other openings.
10) Is this mortise trim tough enough for a high traffic school or hospital corridor door?
The ML2000 Series lock body is heavy-gauge steel and UL cycle tested to 14.5 million cycles (Verification ID V875753), well past a standard commercial requirement, and it is rated Grade 1 for both operation and security. The trim is thru-bolted, which holds alignment and resists pulling. For abuse-prone openings there is also the ML2000VR vandal resistant option with stainless escutcheons, tapered edges and Torx pin tamper-resistant screws.
11) Can I change the function of an ML2000 mortise lock later without buying a whole new lock?
Yes, within the family. Twelve functions are configurable from a single ML2054 lockbody, so a door can move from office to classroom or storeroom duty without swapping the case. Electrified work is handled separately: motorized electric latch retraction (MELR) is offered on the ML20900 series rather than as a field add to a mechanical case.
12) Should I pick the A rose, F rose, or an M or N escutcheon for my mortise trim?
The rose options cover the lever only: A at 2-1/4 inch diameter is the compact one, F at 2-7/8 inch covers a larger area of door face, useful over old fixings or worn finish. The M and N escutcheons are full plates that carry the lever together with the cylinder or thumbturn, spaced 3-5/8 inches lever to cylinder and 2-7/16 inches lever to thumbturn. Escutcheon trim is also where the locked/unlocked status indicator options live, along with sectional trim.
13) Where can I get the parts breakdown for an older Corbin Russwin ML2000 mortise lock?
Corbin Russwin publishes an ML2000 Series Mortise Lock Parts Manual covering locks built prior to 2016, alongside the full ML2000 Series catalog. Between the two you can identify a trim or internal component on an existing installation before ordering a replacement, which matters because the trim designs and finish codes changed over the life of the series.
14) Does the ML2053 close easily on a door with a closer?
The latchbolt is a two-piece mechanical design with an anti-friction insert, 5/8 by 1 inch with a 3/4 inch throw, which takes less force to close than a plain bolt. That matters on fire doors and any opening with a closer set to positive pressure requirements, where a dragging latch is the usual cause of a door not latching.
