Corbin Russwin ML2068-KEYED Privacy/Apartment Mortise Lever Lockset, Grade 1, Field Reversible, 1-3/4" Door

Commercial-Grade Privacy and Apartment Mortise Lock with Patented Quick Reversible Latchbolt

The Corbin Russwin ML2068-KEYED is a Grade 1 Privacy/Apartment Mortise Lever Lockset from the ML2000 Series, engineered for high-traffic commercial, institutional, industrial, and government applications. Designed for 1-3/4" (44mm) standard door thickness, this lockset features a latchbolt operable by grip from either side unless the outside grip is locked, with the outside grip locked or unlocked by key or thumbturn.

Corbin Russwin COR-ML2068-NSA-626 – Frequently Asked Questions

1) Will the Corbin Russwin ML2068 work on a 1-3/4 inch commercial door?
Yes. The ML2068 mortise lockset is built for 1-3/4 inch (44mm) door thickness as standard, with a 2-3/4 inch (70mm) backset. The lock case itself measures 5-7/8 x 4 x 15/16 inches, so the door needs a standard ANSI mortise pocket. Optional thicknesses are available if your opening is thicker than 1-3/4 inches.
2) What does the ML2068 privacy/apartment function actually do at the door?
The latchbolt retracts by the grip on either side unless the outside grip is locked. You lock or unlock the outside grip by key or by thumbturn. The inside grip is always free, so egress is never blocked, and operating the inside grip, closing the door, or using the key unlocks the outside grip again. That auto-release on close is what makes it an apartment function rather than a plain bed/bath privacy set: a tenant cannot walk out and leave the outside grip locked by accident.
3) Do I have to order the ML2068 handed, or can I re-hand it on site?
Order it and re-hand it in the field. The ML2068 uses Corbin Russwin's patented Quick Reversible latchbolt, so the handing is reversed without disassembling the lock case. For a locksmith carrying stock or a property manager standardizing across a building with mixed swings, that means one part number covers both hands.
4) Will the ML2068 latch into the strike prep already in my frame?
It ships with an ANSI straight lip strike, 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center, so it drops into a standard ANSI 4-7/8 frame prep. The two-piece anti-friction latchbolt throws 3/4 inch (19mm) and the auxiliary deadlatch gives 9/16 inch (14mm) effective throw. The one-piece stainless deadbolt throws a full 1 inch (25mm), which needs a strike box deep enough to take it, so check the deadbolt pocket if the frame previously carried a latch-only lock.
5) Can I key the ML2068 into the master key system I already run in the building?
Yes. The ML2068 takes a conventional 6-pin brass cylinder in the L4 keyway, supplied 0-bitted as standard, and it works with new or existing Corbin Russwin key systems. It also accepts most other manufacturers' cylinders, so an existing non-Corbin system can usually be carried over. If you run interchangeable core, order it CL6 (LFIC 6-pin less core) or CL7 (LFIC 7-pin less core) and drop your own cores in; LC (less cylinder) is there if you are supplying a conventional cylinder yourself. Keyed alike is available where you want several doors on one key.
6) Is the ML2068 approved for a 3-hour fire rated apartment entry door?
It is UL and cUL listed to UL10C positive pressure, rated for 3-hour fire doors up to 4 x 10 feet single or 8 x 10 feet pair. It is ANSI/BHMA A156.13 Series 1000, Operational and Security Grade 1, and meets ADA A117.1. It also carries California State Fire Marshal listing and windstorm/hurricane certification, which matters on coastal multi-family work.
7) What do I have to specify when ordering an ML2068 mortise lockset?
Four decisions. Cylinder type is required: standard conventional 6-pin L4, LC less cylinder, CL6 LFIC less 6-pin core, or CL7 LFIC less 7-pin core. Then keying, either keyed different (standard) or keyed alike across a group of doors. Then the lever design, from Armstrong, Citation, Dirke (specified left or right hand), Essex, Lustra, Newport, Princeton or Regis. Then the trim: A rose at 2-1/4 inch diameter, F rose at 2-7/8 inch diameter, or M or N escutcheon. Finish is chosen from fourteen options including 626 satin chrome, 630 satin stainless, 613 oil-rubbed bronze and BSP black suede powder coat.
8) What else could I buy instead of the Corbin Russwin ML2068 for a Grade 1 privacy mortise lock?
Two direct mechanical equivalents. The Cal-Royal NM8440 is a Grade 1 heavy duty privacy mortise lockset with deadbolt for 1-3/4 inch doors. The Hager 3840S is a Grade 1 privacy mortise lock with the same 2-3/4 inch backset as the ML2068, and it covers a door thickness range of 1-3/4 to 2 inches if your doors run thicker than standard. Where the ML2068 pulls ahead is keying: it is a keyed privacy/apartment function with key and thumbturn control of the outside grip, so a manager can get in. If you want the same privacy function but electronic access control instead of a key, the Schlage CO-100 is a standalone Grade 1 privacy mortise lock with a keypad reader for 1-3/4 inch doors.
9) I need locks on a corridor or storeroom door, not an apartment entry. Is the ML2068 the wrong function?
Yes, wrong function. The ML2068 is privacy/apartment: the outside grip unlocks whenever someone operates the inside grip or closes the door, which is exactly what you do not want on a storeroom that must stay locked at all times. For an always-locked outside lever with key entry, look at a storeroom function such as the Accentra 8805FL Grade 1 storeroom mortise lock or the Cal-Royal NM8080. For a classroom, the Cal-Royal NM8070 is the Grade 1 classroom function. For a dormitory or corridor door with a deadbolt, the Sargent 7925 is a Grade 1 heavy duty corridor/dormitory mortise lock.
10) The opening only needs the lever to always turn freely with no locking at all - what mortise lock replaces the ML2068 there?
Use a passage mortise lock instead. The Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, for 1-3/4 inch doors. The Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating. Hager offers passage in the 3800 Series two ways: the 3810S with rose trim and a 2-3/4 inch backset, and the 3810E with escutcheon trim, both 1-3/4 inch to 2-1/2 inch. The ML2068 is the wrong choice for that opening because it is keyed and its outside grip locks by key or thumbturn.
11) What is the difference between the Corbin Russwin ML2068 and the Baldwin 6301 entry/apartment mortise lock?
The Baldwin 6301 is an entrance/apartment function mortise lock body offered knob by knob, or lever by lever as the 6301LS, on a 2-1/2 inch backset for doors 1-3/4 inch and over. The ML2068 is a Grade 1 Privacy/Apartment lever lockset on a 2-3/4 inch backset for 1-3/4 inch doors. Backset is the deciding detail: the two do not share a door prep.
12) My door is 1-5/8 inch thick - will the ML2068 fit, or do I need a different lock?
The ML2068 is built for 1-3/4 inch doors. The Alarm Lock Trilogy electronic mortise locks cover thinner stock: the DL2700CR and the DL3500CR are both Grade 1 classroom function with a door thickness range of 1-5/8 inch to 1-7/8 inch, and the DL4500 is a Grade 1 electronic mortise deadbolt with a privacy keypad over the same 1-5/8 inch to 1-7/8 inch range.
13) If the opening needs the lever electrically locked or unlocked from an access control panel, what mortise lock do I specify?
An electrified mortise lock. The Schlage L9092EU with 03A trim electrically locks or unlocks the outside lever, is keyed outside with request to exit, runs on 12/24VDC, heavy duty, corridor function, 1-3/4 inch door. The Command Access ML190 Series motorized mortise lock is field selectable EL or EU on 24VDC in storeroom function, and the BEST 45HW is a wired electromechanical mortise lock with 12V/24V operation. The ML2068 is a mechanical lock, not electronic; within the Corbin Russwin ML2000 range, motorized electric latch retraction is an ML20900 series option.
14) How far apart are the lever and the cylinder on the ML2068 escutcheon?
Center to center from lever to cylinder is 3-5/8 inches (92mm), and lever to thumbturn is 2-7/16 inches (62mm). Those are the numbers that decide whether an existing escutcheon or a door already prepped for another mortise lock lines up, and they are worth checking against the prep before you cut anything. The armored front is 8 x 1-1/4 inches in wrought brass, bronze or stainless.
15) Should I use a mortise privacy lock like the ML2068 or a cylindrical lock on an apartment entry?
A mortise lock goes into a pocket routed into the door edge and carries both a 3/4 inch latchbolt and a separate 1 inch stainless deadbolt in one case, which is what you want on an apartment or dwelling unit entry where the tenant needs real deadbolt security plus key and thumbturn control. A cylindrical lock bores through the face of the door and is faster to install and easier to retrofit, but a passage cylindrical set like the Schlage PC10 gives you a latch only, no deadbolt and no keying. If the door is already prepped cylindrical and you only need a latch, the cylindrical route is simpler. If the opening is high traffic or needs a deadbolt, mortise is the right family.
16) Is the ML2068 durable enough for a high traffic apartment building or dormitory?
The lock case is heavy-gauge steel and the ML2000 Series has been UL cycle tested to 14.5 million cycles, well past the ANSI/BHMA Grade 1 requirement. It is Operational and Security Grade 1 under A156.13 Series 1000. The two-piece anti-friction latchbolt takes less force to close the door, which matters on doors with closers and stack pressure, and the trim is thru-bolted for alignment and added security under abuse.
17) Is the ML2068 an electronic lock, and can I get electrified access control on an ML2000 mortise lock?
The ML2068 is a mechanical lock, not electronic, keyed with a conventional cylinder and thumbturn. Within the ML2000 family, Motorized Electric Latch Retraction (MELR) is offered on the ML20900 series, so if the opening needs remote release you move to that series rather than electrifying an ML2068. For a standalone credential-based lock on the same kind of opening, the Dormakaba E-Plex 2066 pushbutton keyless mortise lock and the Schlage LEBMB-ADD mobile-enabled mortise lock cover privacy, office and apartment functions.
18) If I standardize on the ML2000 mortise lock body, can I change functions later without buying a whole new lock?
The ML2000 Series is multi-function: twelve functions are configurable from a single ML2054 lockbody. For a facility standardizing across many openings, that means one lock body on the shelf can be set up for the function a given door ends up needing, and a door whose use changes does not force a full replacement. Trim and cylinder still get specified per opening.
19) For a behavioral health or anti-ligature opening, what mortise lockset do I use instead of a standard ML2068 lever?
TownSteel builds the MRX series for that: the MRX-L-01 is a Grade 1 heavy duty stainless steel anti-ligature lever mortise lockset in passage function for 1-3/4 inch doors, and the MRX-A-01 is the same passage function with satin stainless ligature resistant arch trim. Marks USA offers the 5PDN, a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant, ADA compliant, in satin stainless steel. Note those are passage function; the ML2068 is a keyed Privacy/Apartment lock, and its own behavioral health trim options are BHSS and BLSS.
20) What should I use instead of the ML2068 on a classroom door?
Classroom function is a different lock. The Cal-Royal NM8070 is a heavy duty 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 measuring 8-1/2 inch H x 2-3/4 inch W x 7/16 inch. The ML2068 is built for Privacy/Apartment openings, where the inside grip is always free and the outside grip is locked or unlocked by key or thumbturn.
21) Is an electronic mortise lock like the Schlage CO-100 an alternative to the Corbin Russwin ML2068 for apartment doors?
The Schlage CO-100-MS-40-KP is a standalone electronic mortise lock in privacy function with a keypad reader, Grade 1 heavy duty, for 1-3/4 inch doors, so it covers the same door and the same privacy intent by code rather than by key. The ML2068 is mechanical, not electronic, and works from a conventional 6-pin L4 keyway cylinder with a thumbturn. Choosing between them is a question of whether the opening gets credential management or a key system.
22) Can I use a mortise deadbolt such as the Sargent 4874 in place of the ML2068?
Not as a single unit. The Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset, and the Kaba Ilco 185 Series is a no-handing mortise deadbolt; both throw a bolt but neither carries a latch or lever, so the door has no operating trim. The ML2068 is a lever lockset that combines a 3/4 inch latchbolt with a one-piece stainless steel deadbolt at 1 inch throw in one case.
23) Is a dummy mortise trim like the Emtek 3102 or Schlage L0170 a substitute for the ML2068?
No. The Emtek 3102 Memphis and 3104 Hamilton are dummy function mortise entrance locksets, and the Schlage L0170 is a Grade 1 mortise non-keyed half dummy trim for 1-3/4 inch doors. Dummy trim is fixed and operates nothing, used on an inactive leaf. The ML2068 is a keyed working lockset whose latchbolt retracts by grip from either side unless the outside grip is locked.
24) What is the difference between the ML2068 and the Sargent 7925 dormitory function mortise lock?
The Sargent 7925 is a Grade 1 heavy duty corridor/dormitory function mortise lock in the 7900 Series with rose trim and a single cylinder deadbolt. The ML2068 is Grade 1 in Privacy/Apartment function, where the inside grip is always free and operating it, closing the door, or using a key unlocks the outside grip. Both carry a deadbolt; the deciding factor is whether the room is managed as a dormitory corridor opening or an apartment privacy opening.
25) I want to standardize a building on one mortise lock body across several functions - how does the ML2068 compare to the BEST 45H approach?
Both are built around a common lockbody. The BEST 45H Series is a heavy duty mortise lock body offered in public entrance function with field reversible operation, and the 45HCA series covers intruder function on the same heavy duty platform. On the Corbin Russwin side, 12 functions are configurable from one ML2054 lockbody, and the ML2068 is handed with a patented Quick Reversible latchbolt that re-hands without disassembling the lock case.
26) Does the Dormakaba E-Plex E5086 do the same job as the Corbin Russwin ML2068?
They are different locks. The Dormakaba E-Plex E5086 is a Grade 1 entry/egress electronic pushbutton and card back-to-back mortise lock in the E-Plex 5X86 Series, and the E-Plex 2066 is an electronic pushbutton keyless mortise lock for wide stile. Those manage access by code or card. The ML2068 is a mechanical Grade 1 Privacy/Apartment lever lockset, single cylinder keyed, that can run on new or existing Corbin Russwin key systems and accepts most other manufacturers' cylinders.
27) Is there a mortise office function lock to use in place of the ML2068 where the room is an office rather than a bedroom or apartment?
Yes. The Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon, non-keyed, on a 2-3/4 inch backset for doors 1-3/4 inch to 2-1/2 inch, and the Cal-Royal NM8050 is a heavy duty Grade 1 office/entrance mortise lockset with auxiliary deadlatch for 1-3/4 inch doors. The ML2068 shares the 2-3/4 inch backset but is keyed in Privacy/Apartment function.
28) For a multifamily property that wants mobile credentials on apartment doors, what mortise lock competes with the ML2068?
The Schlage Electronics LEBMB-ADD is a mobile-enabled mortise lock with push button and LED covering privacy, office and apartment use, Grade 2, 3 hour fire rating, 1-3/4 inch door. The LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and mobile-enabled deadbolt with LED, Greenwich trim, right hand, 3 hour fire rating. The ML2068 is the mechanical route on the same apartment opening: Grade 1, 1-3/4 inch door, keyed with thumbturn.
29) Will a Marks USA 21AC or 22AC ornamental iron mortise lock work where an ML2068 is specified?
No. The Marks USA 21AC and 22AC are entrance double cylinder ornamental iron mortise locks with a round knob, built for a 1 inch door thickness. The ML2068 is for 1-3/4 inch doors and is a single cylinder lever lockset. The stile thickness alone rules the ornamental iron locks out of a standard commercial opening.
30) For a classroom that needs lockdown from inside plus RFID credentials, what mortise lock covers that instead of the ML2068?
TownSteel builds two: the FME-2000 Series is a Grade 1 heavy duty classroom mortise lockset with RFID technology for 1-3/4 inch doors, and the FME-4000 Series is an electronic intruder classroom mortise lockset with RFID on the same Grade 1 heavy duty, 1-3/4 inch basis. The BEST 45HCA intruder function lockbody is the mechanical equivalent of that inside-lockdown intent. The ML2068 is a Privacy/Apartment function lock and does not provide classroom intruder operation.
31) Can I get the ML2068 in a finish that matches the rest of the doors in the building?
Fourteen finishes are offered: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 satin bronze oil-rubbed, 613E dark oxidized satin bronze equivalent, 618 bright nickel, 619 satin nickel, 625 bright chrome, 626 satin chrome, 629 bright stainless, 630 satin stainless, 722 black oxidized bronze oil-rubbed, and BSP black suede powder coat. 626 and 630 are the usual commercial standards. The trim substrate is brass or bronze.
