Corbin Russwin ML2054LWM626LC – Frequently Asked Questions

1) Does the Corbin Russwin ML2054 mortise lock come with a cylinder?
No. The ML2054 as configured is a less-cylinder lock, so you supply the cylinder. It can be keyed into new or existing Corbin Russwin key systems, and it accepts most other manufacturers' mortise cylinders, so an existing keyway on the building can usually be carried over. Corbin Russwin's own cylinder spec is brass, 6-pin L4 keyway, 0-bitted as standard.
2) Will the ML2054 mortise lock fit a 1-3/4 inch door with a 2-3/4 inch backset prep?
That is exactly its standard prep: 1-3/4 inch (44mm) door thickness and a 2-3/4 inch (70mm) backset. The steel lockcase measures 5-7/8 x 4 x 15/16 inches and the armored front is 8 x 1-1/4 inches, which is the standard ANSI mortise pocket. Optional door thicknesses are available if your doors are thicker than 1-3/4 inches.
3) Do I need to order the ML2054 handed, or can it be reversed in the field?
Order it and re-hand it on site. The ML2054 uses Corbin Russwin's patented Quick Reversible latchbolt, so handing is changed without disassembling the lock case, and the catalog data lists the lock as field reversible. That is useful when you are stocking spares across a building with both left and right hand openings.
4) Will the ML2054 latch into my existing ANSI mortise strike?
In most cases yes. It ships with a wrought brass, bronze or stainless ANSI straight lip strike measuring 4-7/8 x 1-1/4 x 1-1/8 inches lip to center, which is the standard commercial frame prep. Latchbolt throw is 3/4 inch (19mm) with a two-piece anti-friction insert, plus a 9/16 inch deadlocking auxiliary latch, and the deadbolt throws a full 1 inch, so the frame needs the deadbolt pocket as well as the latch cutout.
5) Can the ML2054 be used on a fire rated door?
Yes. The ML2000 Series lock is UL/cUL listed and UL10C positive pressure rated, good for 3-hour fire doors up to 4 x 10 feet single or 8 x 10 feet pair. It is also ANSI/BHMA A156.13 Series 1000 Grade 1 for both operational and security, listed to ADA A117.1, California State Fire Marshal, and windstorm/hurricane certified.
6) What is a comparable Grade 1 mortise lock to the Corbin Russwin ML2054 if the opening calls for storeroom function instead of entry?
The Corbin Russwin ML2054 is an entry-function Grade 1 mortise lock in the ML2000 Series. For a storeroom opening, the Accentra 8805FL is a Grade 1 mortise lock in the 8800 Series with storeroom function and an Arcadia lever, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option. Storeroom function keeps the outside lever fixed at all times with key access only, where entry function allows the outside lever to be locked or unlocked.
7) Which Grade 1 mortise lock should I use instead of the Corbin Russwin ML2054 on a classroom door?
The ML2054 is configured for entry use, so for a classroom opening the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with auxiliary deadlatch for 1-3/4 inch doors, and the Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset for 1-3/4 inch doors with an ANSI strike and a steel escutcheon 8-1/2 inch H x 2-3/4 inch W x 7/16 inch. The Marks unit adds visual indication of lock status at the door.
8) What do I use instead of the Corbin Russwin ML2054 if the door needs privacy function for a restroom?
The ML2054 is a keyed entry mortise lock and is not a privacy set. For a bed/bath or restroom opening, the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors, and the Hager 3840S in the 3800 Series is a Grade 1 privacy mortise lock with a 2-3/4 inch backset for doors 1-3/4 inch to 2 inch thick. Both use the same 2-3/4 inch backset as the ML2054.
9) What is the equivalent to the Corbin Russwin ML2054 if I need credential or keypad access rather than a key?
The ML2054 is a mechanical, non-electronic mortise lock. For electronic access in the same mortise prep, the Dormakaba E-Plex E5086 is a Grade 1 electronic pushbutton and card mortise lock with entry/egress function, the Schlage CO-100 is a Grade 1 standalone electronic mortise lock with keypad reader for 1-3/4 inch doors, and the TownSteel FME-2000 is a Grade 1 heavy duty mortise lockset with RFID technology for 1-3/4 inch doors. All three add power and credential management that the ML2054 does not require.
10) Can I use a Baldwin 6301 or 6310 mortise lock body in place of the Corbin Russwin ML2054?
Not without changing the door prep. The Corbin Russwin ML2054 uses a 2-3/4 inch backset with an ANSI straight lip strike 4-7/8 inch x 1-1/4 inch x 1-1/8 inch lip to center. The Baldwin 6301 entry/apartment mortise lock body and the Baldwin 6310 entry/storeroom mortise lock body are both 2-1/2 inch backset, so the cross bore and case pocket locations differ. The 6301 is rated for doors 1-3/4 inch and over; the 6310 for 1-3/8 inch and over.
11) Which mortise lock is comparable to the Corbin Russwin ML2054 when the opening needs electric lock or unlock control from the access system?
The ML2054 is a mechanical lockset with no electrical option on the body. For electrified control in a mortise prep, the Schlage L9092EU with 03A trim is a heavy duty corridor-function mortise lock for 1-3/4 inch doors, keyed outside, with electric lock/unlock of the outside lever, request to exit, and 12/24VDC operation. The Command Access ML190 is a heavy-duty motorized mortise lock with field selectable EL or EU operation at 24VDC and storeroom function, and the BEST 45HW is a heavy duty wired electromechanical mortise lock with 12V/24V operation. These require power transfer through the door frame, which the ML2054 does not.
12) What is the closest alternative to the Corbin Russwin ML2054 for a general office or entrance door on a 1-3/4 inch leaf?
The Cal-Royal NM8050 is a heavy duty Grade 1 office/entrance mortise lockset with auxiliary deadlatch for 1-3/4 inch doors, which matches the ML2054 on grade, door thickness and general entrance use. The Hager 3850E in the 3800 Series is a Grade 1 office mortise lock with lever and escutcheon on a 2-3/4 inch backset, though it is non-keyed, where the ML2054 is a single cylinder keyed lock supplied less cylinder.
13) If I need an intruder or lockdown function rather than the Corbin Russwin ML2054 entry function, what are the options?
The ML2054 is an entry lock and does not provide inside lockdown. The BEST 45HCA heavy duty mortise lockbody offers intruder function, and the TownSteel FME-4000 is a Grade 1 heavy duty electronic intruder classroom mortise lockset with RFID technology for 1-3/4 inch doors. Intruder function allows the door to be secured from the inside without opening it, which entry function does not.
14) What does the 54 function on an entry mortise lock actually do at the door?
The ML2054 is a single cylinder entry function, catalogued under corridor use. The lever retracts the latch, the key on the outside controls it, and there is a separate 1 inch stainless deadbolt operated from the inside thumbturn side, so you get life safety egress and deadbolt security in one door prep. The same ML2054 lockbody is configurable to 12 functions, which matters if you are standardizing a building on one body and changing function later.
15) How far apart are the lever and the cylinder on the ML2054 escutcheon?
Center to center from the lever to the cylinder is 3-5/8 inches (92mm), and lever to thumbturn is 2-7/16 inches (62mm). Those are the numbers to check against an existing escutcheon cutout or a door already bored for another brand's trim before you commit.
16) Is this mortise lock heavy duty enough for a high traffic school or hospital corridor?
It is built for that traffic. Heavy-gauge steel lockcase, brass or bronze substrate trim, Grade 1 operational and security, and UL cycle tested to 14.5 million cycles (Verification ID V875753). Corbin Russwin lists it for commercial offices, schools, healthcare, hotels, industrial, and government work.
17) What trim and finish does this ML2054 configuration come with?
This build is the wrought Lustra lever (LW) on an M escutcheon in 626 satin chrome. The ML2000 Series also offers other trim families including Museo, Vineyard, and Behavioral Health (BHSS/BLSS), plus status indicator options showing locked/unlocked on sectional and escutcheon trim. All trim designs are thru-bolted for alignment and added security.
18) I need an electrified version of this mortise lock instead of a mechanical one. What are my options?
The ML2054 itself is mechanical, not electronic. Corbin Russwin offers Motorized Electric Latch Retraction (MELR) on the ML20900 series if you need the latch pulled electrically. If you want a different brand, ZenSupply carries the Command Access ML190 Series motorized mortise lock with field selectable EL/EU operation on 24VDC, and the Schlage L9092EU electric lock/unlock mortise lock with request-to-exit and 12/24VDC on a corridor function.
19) What are the alternatives to a Corbin Russwin ML2054 if I want a Grade 1 entry mortise lock from another brand?
For a keyed office/entrance function on the same 1-3/4 inch door, the Cal-Royal NM8050 is a Grade 1 heavy duty office/entrance mortise lockset with auxiliary deadlatch. The Accentra 8805FL from the 8800 Series is a Grade 1 storeroom function if you want the door always locked from outside. The Sargent 7925 from the 7900 Series is a Grade 1 heavy duty corridor/dormitory function with rose trim and a single cylinder deadbolt, which is closest to the ML2054's corridor role.
20) Why choose a mortise lock like the ML2054 over a cylindrical lockset?
A mortise lock puts the latch and a 1 inch deadbolt in one pocket in the door edge, so you get keyed entry and deadbolt security in a single prep, with a heavy-gauge steel case sized 5-7/8 x 4 x 15/16 inches. That is why mortise is specified on corridor and entry openings in commercial buildings. A cylindrical lock such as the Schlage PC10 bores through the face of the door and is quicker to install, but it carries no deadbolt. If the door is already prepped cylindrical, retrofitting to mortise means a new edge pocket.
21) Will the Alarm Lock DL3500CR or DL2700CR work on the same doors as the Corbin Russwin ML2054?
Check the door thickness first. The Corbin Russwin ML2054 is built for 1-3/4 inch doors as standard, with optional thicknesses available. The Alarm Lock DL3500CR and DL2700CR are both Grade 1 electronic classroom mortise locks specified for doors 1-5/8 inch to 1-7/8 inch, so a 1-3/4 inch door falls inside their range. Function differs, however: both Alarm Lock units are classroom function with keypad credentials, while the ML2054 is a keyed entry lock.
22) Is there a Grade 1 mortise lock like the Corbin Russwin ML2054 that also provides corridor or dormitory function?
The Corbin Russwin ML2054 is an entry mortise lock in the ML2000 Series with a 1 inch stainless steel deadbolt. The Sargent 7925 is a heavy duty Grade 1 mortise lock in the 7900 Series with corridor/dormitory exit function, rose trim and a single cylinder deadbolt. The ML2054 shown here carries an M escutcheon rather than a rose, which changes the door prep and the trim appearance.
23) Is there a simpler non-keyed alternative to the Corbin Russwin ML2054 for an opening that does not need to lock?
Yes. The ML2054 is a keyed single cylinder entry mortise lock. Where no locking is required, the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, the Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation, and the Hager 3810E is a Grade 1 passage mortise lock with escutcheon and a 2-3/4 inch backset for doors 1-3/4 inch to 2-1/2 inch. The 3810S is the same passage function with rose trim instead of an escutcheon.
24) Is the Sargent 4874 mortise deadbolt a substitute for the Corbin Russwin ML2054?
No. The Corbin Russwin ML2054 is a complete entry lockset with a 3/4 inch throw anti-friction latchbolt plus a 1 inch throw stainless steel deadbolt and lever trim. The Sargent 4874 in the 4870 Series is a double cylinder mortise deadbolt with a 2-3/4 inch backset and no latch or lever operation, and the Kaba Ilco 185 Series is likewise a deadbolt-function mortise lock with no handing. Those are deadbolt-only devices used alongside a latch, not in place of a lockset.
25) What mortise lockset do I use instead of the Corbin Russwin ML2054 in a behavioral health or ligature-resistant application?
The ML2054 offers Behavioral Health BHSS and BLSS trim options within its trim range. Purpose-built alternatives include the TownSteel MRX-L-01, a Grade 1 heavy duty anti-ligature lever mortise lockset in stainless steel with passage function for 1-3/4 inch doors, the TownSteel MRX-A-01 with ligature-resistant arch trim, and the Marks USA 5PDN, a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant in satin stainless steel. All three are passage function, so they do not provide the keyed entry control the ML2054 does.
26) Are the Emtek 3102 and 3104 mortise entrance locksets alternatives to the Corbin Russwin ML2054?
No. The Corbin Russwin ML2054 is an operating Grade 1 entry mortise lock with a latchbolt and a 1 inch throw deadbolt. The Emtek 3102 Memphis, 3104 Hamilton, 3106 Manhattan and 3019 Brisbane mortise entrance locksets are dummy function, meaning fixed trim with no latch or locking mechanism, used on inactive leaves and closet faces.
27) Which other mortise lock bodies are field reversible like the Corbin Russwin ML2054?
The Corbin Russwin ML2054 uses a patented Quick Reversible latchbolt that lets the handing be changed without disassembling the lock case. Among comparable heavy duty bodies, the BEST 45H public entrance mortise lock body is field reversible, and the Falcon MA101 Grade 1 heavy duty mortise passage lock also offers field reversible operation. The Kaba Ilco 185 Series is supplied with no handing at all. Function differs across these, so match the function to the opening before choosing on reversibility alone.
28) Is the Schlage PC10 cylindrical lock a substitute for the Corbin Russwin ML2054?
No, the door prep is different. The Corbin Russwin ML2054 is a mortise lock requiring a rectangular case pocket in the door edge, 5-7/8 inch x 4 inch x 15/16 inch. The Schlage PC10 is a Grade 1 passage cylindrical lock with rose for 1-3/4 inch doors, which uses a bored cross hole rather than a mortise pocket, and it is non-keyed. A mortised door cannot take a cylindrical lock without filling the pocket.
29) Which mortise locks compare to the Corbin Russwin ML2054 on 3-hour fire rating for a labeled opening?
The Corbin Russwin ML2054 is UL/cUL listed to UL10C positive pressure for 3-hour fire doors up to 4 ft x 10 ft single or 8 ft x 10 ft pair. Among comparable electronic mortise locks, the Schlage LEMD is a Grade 1 ENGAGE Series wireless mortise lock with a 3-hour fire rating, and the Schlage LEBMB is a Grade 2 mobile-enabled mortise lock also rated 3 hours for 1-3/4 inch doors. The Falcon MA101 Grade 1 heavy duty mortise passage lock is fire rated as well.
30) Is the ML2054 ADA compliant for lever operation?
Yes, the ML2000 Series lock is listed to ADA A117.1, and the lever trim supplied here is the wrought Lustra design, which is lever rather than knob operation. That matters on accessible routes in schools, healthcare, and public buildings where knobs are not permitted.
