Corbin Russwin COR-ML2060-NSA-626 – Frequently Asked Questions

1) Will the Corbin Russwin ML2060 privacy lock fit a 1-3/4 inch door with a 2-3/4 inch backset prep?
That is exactly the prep the ML2060 is built around: 1-3/4 inch (44mm) door thickness with a 2-3/4 inch (70mm) backset, which is the standard commercial mortise prep. Optional thicknesses are available on the ML2000 Series, but the standard build is the 1-3/4 inch door. The lock case itself is heavy-gauge steel at 5-7/8 x 4 x 15/16 inches, and the armored front measures 8 x 1-1/4 inches, so it drops into a standard ANSI mortise pocket.
2) How does the ML2060 privacy function actually work, and can someone get in from the corridor in an emergency?
The latchbolt works by grip from either side, except when the outside grip is locked by the inside thumbturn. Turning the inside grip, closing the door, or using an emergency key from the outside unlocks the outside grip again. The inside grip is always free, so a person can always get out. That is the ANSI F22 privacy function, and the emergency key release is what facilities staff use to get into an occupied restroom or patient room.
3) Do I have to specify hand when ordering a Corbin Russwin ML2060, or can I re-hand it on site?
Handing is field reversible. The ML2000 Series uses Corbin Russwin's patented Quick Reversible latchbolt, so the hand is reversed without taking the lock case apart. For a locksmith carrying stock, that means one lock body covers left and right hand openings. The one place hand still matters at order time is the Dirke lever, which is specified as a left hand or right hand lever.
4) Will the ML2060 latch into the strike already in my frame?
The 3/4 inch (19mm) throw two-piece anti-friction latchbolt is sized for a standard ANSI strike, and the lock ships with a wrought brass, bronze or stainless ANSI straight lip strike measuring 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center. If your frame already carries an ANSI 4-7/8 inch strike cutout, the latch lines up. The 1 inch stainless deadbolt throw needs the deadbolt pocket in that same ANSI strike, so a frame prepped only for a latch-only strike will need the strike swapped.
5) Can I use a Corbin Russwin ML2060 on a fire rated door?
Yes. The ML2000 Series is UL/cUL listed and UL10C positive pressure rated for 3 hour fire doors up to 4 by 10 feet single and 8 by 10 feet pair. It also meets ADA A117.1, carries California State Fire Marshal listing, and is windstorm/hurricane certified. Note that this is the privacy function, so it is used on restrooms, patient rooms and dorm rooms rather than on a rated corridor opening that needs a keyed or classroom function.
6) Is the ML2060 a keyed lock, and does it take a cylinder?
The ML2060 is non-keyed. It is the privacy function, locked by a thumbturn on the inside, with an emergency key release outside rather than a full keyed cylinder function. If you need a lock that keys into your master key system on this same 2-3/4 inch backset mortise prep, you want a keyed function from the ML2000 Series instead, not the 2060.
7) What do I have to specify when ordering an ML2060 besides the lock itself?
Three choices make up the order. Lever design: Armstrong, Citation, Dirke (left or right hand), Essex, Lustra, Newport, Princeton or Regis. Trim: A rose at 2-1/4 inch diameter, F rose at 2-7/8 inch diameter, or M or N escutcheon. And finish, from 605 bright brass through 630 satin stainless, 722 black oxidized bronze oil-rubbed and BSP black suede powder coat. Trim is thru-bolted for alignment, and the spacing on the door face is 3-5/8 inches center to center from knob/lever to cylinder and 2-7/16 inches from knob/lever to thumbturn.
8) What other Grade 1 privacy mortise locks could I use instead of the Corbin Russwin ML2060?
Two straight mechanical alternatives we carry. The Cal-Royal NM8440 is a heavy duty Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors. The Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset covering 1-3/4 to 2 inch doors, which is the one to look at if your doors run thicker than 1-3/4 inches. If you need privacy with electronic access control instead, the Schlage CO-100 is a Grade 1 standalone electronic mortise lock in privacy function for 1-3/4 inch doors.
9) My doors are 1-5/8 to 1-7/8 inch thick. Is the ML2060 still the right mortise lock?
Not as the standard build. The ML2060 is specified for a 1-3/4 inch door; optional thicknesses exist within the ML2000 Series but the catalogued standard is the single thickness. For a range that spans 1-5/8 to 1-7/8 inches, the Alarm Lock Trilogy DL2700CR and DL3500CR are Grade 1 mortise locks stated for that range, and the Hager 3840S privacy mortise covers 1-3/4 to 2 inch doors on a 2-3/4 inch backset.
10) For a behavioral health or patient room, is the ML2060 the right mortise lock or is there a ligature resistant option?
For anti-ligature openings, the TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in stainless steel for 1-3/4 inch doors, and the MRX-A-01 is the ligature resistant arch trim version in satin stainless steel; both are passage function. The Marks USA MAR5PDN is a Grade 1 hospital passage mortise push/pull paddleset, ligature resistant and ADA compliant in satin stainless steel. Those are passage function, so they do not lock; the ML2060 is a privacy function with a thumbturn, offered with Behavioral Health BHSS and BLSS trim.
11) What is the closest Grade 1 mortise privacy lock to the Corbin Russwin ML2060 from another manufacturer?
The Cal-Royal NM8440 is a heavy duty Grade 1 privacy mortise lockset with deadbolt, listed for 1-3/4 inch doors, the same door thickness the ML2060 is built around. The Hager 3840S is a Grade 1 privacy mortise lock on a 2-3/4 inch backset, matching the ML2060 backset, and covers doors from 1-3/4 inch to 2 inch. Both carry the same privacy/bed/bath function as the ML2060, which operates the latchbolt by grip from either side except when the outside grip is locked by the thumbturn inside.
12) What should I use instead of the ML2060 on a door that needs a keyed lock rather than a thumbturn?
The ML2060 is a non-keyed privacy function, so it is the wrong choice where a key is required. For a keyed storeroom opening, the Accentra 8805FL is a Grade 1 storeroom mortise lock from the 8800 Series, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors. For an office or entrance opening, the Cal-Royal NM8050 is a Grade 1 office/entrance mortise lockset with auxiliary deadlatch. For a classroom, the Cal-Royal NM8070 is the Grade 1 classroom equivalent.
13) What looks like a mortise privacy lock but will not give me a working privacy latch?
Dummy trim carries no latch and no locking mechanism, so it will not substitute for the ML2060. The Schlage L0170 is Grade 1 mortise non-keyed dummy lever trim for 1-3/4 inch doors, and the Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton and 3106 Manhattan are all dummy function mortise entrance locksets. A mortise thumbturn alone is also not a lock: the Sargent 130KB is a standard mortise thumbturn from the 8200 Series and the 130W is a mortise thumbturn with round backplate, while the ML2060 supplies the thumbturn as part of a complete privacy lockset with a 3/4 inch latchbolt.
14) Which mortise lock should I choose if the opening needs to be released or controlled from an access control system?
The ML2060 is a mechanical, non-electronic privacy lockset, so it cannot be released electrically as supplied. For electrified mortise, the Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock, keyed outside, with request to exit and 12/24VDC operation for 1-3/4 inch doors. The BEST 45HW is a heavy duty wired electromechanical mortise lock with 12V/24V operation. The Command Access ML190 is a heavy-duty motorized storeroom mortise lock with field selectable EL/EU operation on 24VDC. Within the Corbin Russwin family, Motorized Electric Latch Retraction is available on the ML20900 series.
15) Is the Schlage LE Series mobile-enabled mortise lock an equivalent to the ML2060 for privacy openings?
The Schlage LEBMB-ADD is a mobile-enabled mortise lock with push button and LED covering privacy, office and apartment functions, rated Grade 2 with a 3 hour fire rating for 1-3/4 inch doors. The ML2060 is ANSI/BHMA Grade 1 per A156.13 Series 1000 and UL10C listed for 3-hour fire doors up to 4 by 10 feet single or 8 by 10 feet pair. If the specification calls for Grade 1 mechanical, the LEBMB-ADD does not meet it; if credentialed access is the requirement, the ML2060 does not offer it.
16) I need matching mortise locks across a whole building. Will other functions match the ML2060 trim and prep?
They will. The ML2000 Series is multi-function, with 12 functions configurable from a single ML2054 lockbody, and every function shares the same 2-3/4 inch backset and 5-7/8 x 4 x 15/16 inch case, so one door prep covers the building. Order the ML2060 for restrooms and bedrooms and a keyed function from the same series for offices and storerooms, all on the same lever design, rose or escutcheon, and finish. That is how you standardize a school or hospital floor without carrying two door preps.
17) How durable is the Corbin Russwin ML2060 for a high traffic restroom door?
It is built to ANSI/BHMA A156.13 Series 1000, Operational and Security Grade 1, which is the top commercial durability grade, and Corbin Russwin has UL cycle tested the ML2000 Series to 14.5 million cycles. The case is heavy-gauge steel with a one-piece stainless steel deadbolt and a deadlocking auxiliary latchbolt with 9/16 inch effective throw. For a public restroom taking hundreds of operations a day, that is the right grade of lock.
18) Can I get a Corbin Russwin ML2060 with an occupancy indicator showing occupied or vacant?
Status indicator options for locked/unlocked visibility are available on the ML2000 Series with sectional and escutcheon trim. On a privacy lock that is the occupied/vacant readout facilities managers ask for on restrooms and patient rooms. Specify it with the trim, since it ties to the sectional rose or the M or N escutcheon rather than to the lock body.
19) If a door only needs to latch and never lock, is there a simpler alternative to the ML2060 privacy lock?
Yes. A passage function has no locking at all, where the ML2060 locks the outside grip by thumbturn. 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 from the MA Series with field reversible operation and a fire rating, comparable to the ML2060 being field reversible. The Hager 3810S is a Grade 1 passage mortise lock with rose trim on a 2-3/4 inch backset, and the Hager 3810E is the same passage function with escutcheon trim.
20) Can I put an ML2060 on a 1-5/8 inch door, and what mortise locks cover that thickness?
The ML2060 is built for a 1-3/4 inch (44mm) door as standard, with optional thicknesses available. Peers that state a range starting below that include the Alarm Lock DL2700CR and DL3500CR, both Grade 1 classroom function electronic mortise locks covering 1-5/8 inch to 1-7/8 inch, and the Alarm Lock DL4500 Series Grade 1 electronic mortise deadbolt over the same 1-5/8 inch to 1-7/8 inch range. The Baldwin 6310 mortise lock body is listed for 1-3/8 inch and over on a 2-1/2 inch backset, where the ML2060 uses a 2-3/4 inch backset.
21) Does a dormitory or corridor function mortise lock do the same job as the ML2060?
No. The Sargent 7925 is a Grade 1 heavy duty dormitory exit function mortise lock with rose trim and a single cylinder deadbolt from the 7900 Series - the deadbolt is thrown by key or turn and the outside is keyed. The ML2060 is non-keyed: its 1 inch stainless steel deadbolt is part of a privacy function where operating the inside grip, closing the door, or using the emergency key outside unlocks the outside grip.
22) If I only need a deadbolt on the door and no latch, what mortise options are there besides the ML2060?
The ML2060 combines a 3/4 inch throw latchbolt with a 1 inch stainless steel deadbolt in one lock case, so it is more than a deadbolt-only prep. For deadbolt-only mortise preps, the Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset, the same backset the ML2060 uses, and the Kaba Ilco 185 Series is a no-handing mortise deadbolt sold in a single pack.
23) Can I use a cylindrical lock instead of the ML2060 if the door is not prepped for a mortise pocket?
Yes, if the function suits. The Schlage PC10 is a Grade 1 non-keyed passage cylindrical lock with rose for 1-3/4 inch doors - it needs a bored prep rather than the mortise pocket the ML2060 requires for its 5-7/8 inch by 4 inch by 15/16 inch steel lock case. The trade is function: the PC10 is passage only, with no privacy locking.
24) We are standardizing a facility on one mortise lock body across functions - how does the ML2060 compare to lock bodies sold separately?
The ML2000 Series supports 12 functions configured from a single ML2054 lockbody, so one body covers a range of openings and the ML2060 privacy is one of those configurations. The BEST 45H is a heavy duty mortise lock body sold as a public entrance function with field reversible operation, and the BEST 45HCA is a heavy duty mortise lockbody with intruder function - those are bodies for a specific function rather than a multi-function platform. The ML2060 is also field reversible, re-handed without disassembling the lock case.
25) Which mortise locks fit an aluminum storefront or glass door rather than taking the ML2060?
The ML2060 is a commercial lockset for a 1-3/4 inch door with a mortise pocket sized for a 5-7/8 inch by 4 inch case. For storefront and glass openings, the Alarm Lock DL1300NW is a Trilogy Networx wireless electronic mortise lock with keypad made for Adams Rite deadlatches, the Dormakaba E-Plex E2066 is an electronic pushbutton keyless mortise lock for wide stile doors, and the Kaba Ilco BR Series is a glass door bottom rail lock.
26) Does the ML2060 accept cylinders from other manufacturers, or do I have to change key systems?
The ML2060 can be used with new or existing Corbin Russwin key systems and accepts most other manufacturers' cylinders; it ships with a brass 6-pin L4 keyway cylinder, 0-bitted as standard. If the facility is standardized on interchangeable cores instead, the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset offered with an interchangeable core option.
27) For a hotel guest room, is the ML2060 the right lock or should I look at an RFID mortise lockset?
The ML2060 is a mechanical privacy lockset listed for hotel and hospitality properties among its applications. Where guest room credentials are needed, the Dormakaba Saffire LX-I-M002 is an electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2, and the TownSteel FME-2000 is a Grade 1 heavy duty mortise lockset with RFID for 1-3/4 inch doors in classroom function. The ML2060 remains the mechanical Grade 1 choice where no credential system is in play.
28) Is there a vandal resistant version of the Corbin Russwin ML2000 mortise lock?
The ML2000VR Vandal Resistant option uses stainless steel escutcheons with tapered edges and Torx pin tamper-resistant screws. It is aimed at high-risk openings, public restrooms, detention-adjacent corridors and transit facilities where standard trim gets pried or unscrewed. Standard ML2000 trim is thru-bolted, which already resists trim removal from the outside, but the VR trim adds the tamper-resistant fasteners.
29) What finishes does the Corbin Russwin ML2060 mortise privacy lock come in?
Fourteen finishes, covering brass, bronze, nickel, chrome and stainless: 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. For matching an existing building, 626 satin chrome and 630 satin stainless are the two commercial standards; the substrate is brass or bronze.
