Corbin Russwin ML2054-NSA-626-M31 – Frequently Asked Questions

1) Is the Corbin Russwin ML2054-M31 the complete mortise lock or just the lever trim?
Trim only. The ML2054-M31 is the lever trim for an ML2000 Series mortise lockset, sold as a replacement part, so it does not include a lockbody. If the existing ML2000 case in the door is sound and you are replacing damaged or worn levers, this is the right part. If the door has no mortise lock in it yet, or the case itself has failed, you need a complete ML2000 lockset instead.
2) Will Corbin Russwin ML2054 lever trim work on a left hand door if I ordered right hand?
Handing is field reversible on this trim, so one part covers both hands and you reverse it on the job without disassembling the lock case. The one exception is the Dirke lever, which is ordered specifically as DS Left Hand or DS Right Hand. Every other lever style (Armstrong, Citation, Essex, Lustra cast and wrought, Newport, Princeton, Regis) is hand neutral.
3) What do I have to specify when ordering Corbin Russwin ML2054 lever trim?
Three things decide the part number: lever design, rose or escutcheon, and finish. Lever choices are Armstrong (AS), Citation (CS), Dirke (DS, ordered left or right hand), Essex (ES), Lustra cast (LS), Lustra wrought (LW), Newport (NS), Princeton (PS) and Regis (RS). Mounting is A rose at 2-1/4 inch diameter, F rose at 2-7/8 inch diameter, M escutcheon or N escutcheon. The M31 designation in ML2054-M31 is the M escutcheon with the Newport lever. Finishes run from 605 bright brass through 630 satin stainless to BSP black suede powder coat, 14 in all.
4) Will Corbin Russwin ML2054 trim fit my 1-3/4 inch door?
1-3/4 inches is the standard door thickness for the ML2000 Series and optional thicknesses are available for anything else. The lock prep behind it is a 2-3/4 inch backset mortise pocket taking a 5-7/8 x 4 x 15/16 inch case with an 8 x 1-1/4 inch armored front. If your existing prep matches that, the trim lands on the same holes. Note the trim is thru-bolted, so both faces have to be accessible during install.
5) Is the Corbin Russwin ML2054 mortise lock fire rated for a 3 hour opening?
UL and cUL listed, UL10C positive pressure, rated to 3 hours on a single door up to 4 by 10 feet or a pair up to 8 by 10 feet. It also carries ANSI/BHMA A156.13 Series 1000 Grade 1 for both operational and security, ADA A117.1 compliance, California State Fire Marshal listing, and windstorm and hurricane certification. For a facility standard on fire-rated openings, that combination is the one to write into the spec.
6) Will the ML2054 latch into the strike that is already in my frame?
The latchbolt is a two-piece anti-friction unit measuring 5/8 x 1 inch with a 3/4 inch (19mm) throw, backed by a deadlocking auxiliary latch at 9/16 inch effective throw, and the deadbolt is one-piece stainless at 19/32 x 1-1/4 inch with a 1 inch throw. The matching strike is an ANSI straight lip, 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center. If your frame already has an ANSI 4-7/8 inch strike prep at a 2-3/4 inch backset, the bolts land. A frame cut for a cylindrical lock strike will not take it.
7) Can I use my existing Corbin Russwin keys with an ML2054 entrance lock, or do I have to rekey the building?
The ML2000 works with new or existing Corbin Russwin key systems and accepts most other manufacturers' cylinders, so an opening on an established masterkey system stays on it. The standard cylinder is brass, 6-pin, L4 keyway, shipped 0-bitted, which means your locksmith pins it to your system rather than you living with a factory key. If you are running a different manufacturer's keyway across the property, the cylinder is the part you swap, not the lock.
8) Can I match Corbin Russwin ML2054 trim to the satin chrome levers already on my other doors?
626 satin chrome is one of the 14 finishes offered, and so is 630 satin stainless, the other common commercial match. The full range covers bright and satin brass (605, 606), bright and satin bronze (611, 612), oil-rubbed bronze (613) and its dark oxidized equivalent (613E), bright and satin nickel (618, 619), bright chrome (625), bright stainless (629), black oxidized oil-rubbed bronze (722) and black suede powder coat (BSP). For a fleet of openings, pick the finish code off an existing lever rather than by eye, since 613, 613E and 722 read similarly dark but are distinct finishes.
9) What is the difference between the A rose, F rose, and M or N escutcheon on Corbin Russwin ML2000 trim?
It is the size and shape of the plate behind the lever, and it decides what it covers on the door face. The A rose is a 2-1/4 inch diameter round plate and the F rose is 2-7/8 inch diameter, both round. The M and N escutcheons are full plates rather than roses, which is what you want when the trim has to cover old prep or when you are running a status indicator, since indicator options are offered on sectional and escutcheon trim. On the ML2054 the cylinder sits 3-5/8 inches center to center from the lever, so an escutcheon is what carries both on one plate.
10) Is an ML2054 entrance function mortise lock the right choice for a school or hospital corridor door, or should I look at something else?
Entrance function is for an opening people key in and out of and where you want a deadbolt as well as a latch, which is what the ML2054 gives you: a 1 inch throw stainless deadbolt alongside a 3/4 inch throw anti-friction latchbolt. The anti-friction latch takes less force to close, which matters on a door with a closer. For behavioral health areas Corbin Russwin offers BHSS and BLSS trim designs on the same series, and where you need remote release there is Motorized Electric Latch Retraction on the ML20900 series. A classroom or storeroom function is a different ML2000 number, not this one.
11) How much traffic will Corbin Russwin ML2000 mortise hardware take before it wears out?
UL cycle tested to 14.5 million cycles (Verification ID V875753), on top of the ANSI/BHMA A156.13 Grade 1 operational and security rating and a heavy-gauge steel lockcase. For context on a high-traffic opening, that is the number to put against a main entrance, a school corridor or a hospital wing where a residential-grade lever would be replaced repeatedly.
12) Can one ML2054 lockbody be reconfigured to a different function later?
Twelve functions are configurable from a single ML2054 lockbody, so a stocked spare covers several openings and a function change on an existing door does not always mean a new lock. That is worth knowing for an MRO crib standardizing on one series: fewer part numbers on the shelf, and the Quick Reversible latchbolt means the same unit handles either door hand.
13) How do I identify the right replacement lever for an older Corbin Russwin mortise lock?
Corbin Russwin publishes an ML2000 Series parts manual covering locks made prior to 2016, plus the full ML2000 Series catalog, and between them you can match the lever design, rose or escutcheon, and finish code on what is in the door. Start from the escutcheon or rose shape (A rose is 2-1/4 inch round, F rose 2-7/8 inch round, M and N are escutcheons), then the lever design, then read the finish code stamped on the part.
