Corbin Russwin ML2030 Mortise Privacy Lock for Bedroom and Bathroom, Grade 1 with Field Reversible Handing

Commercial-Grade Mortise Privacy Solution for High-Traffic Institutional and Commercial Applications

The Corbin Russwin ML2030 is a Grade 1 mortise privacy lockset engineered for bedroom and bathroom applications in demanding commercial, institutional, industrial, and government environments. Conforming to ANSI function F19, this lockset allows latchbolt operation by grip from either side unless the outside grip is locked by thumbturn, while the deadbolt is operated by thumbturn from inside or by emergency release tool from outside.

    Corbin Russwin COR-ML2030-NSA-626 – Frequently Asked Questions

    1) Will the Corbin Russwin ML2030 privacy mortise lock fit a 1-3/4 inch door with a 2-3/4 inch backset prep?
    That's exactly the prep the ML2030 is built for: 1-3/4 inch (44mm) door thickness standard and a 2-3/4 inch (70mm) backset. Optional thicknesses are available if your doors are heavier than standard. The lockcase measures 5-7/8 x 4 x 15/16 inches, so the existing mortise pocket on a standard commercial ANSI mortise prep takes it directly.
    2) How does the ML2030 bathroom lock actually operate from each side?
    Grip on either side retracts the latchbolt unless someone has locked the outside grip with the inside thumbturn. The deadbolt throws by thumbturn from inside only, and from outside it can be released with an emergency tool. That is ANSI function F19, the standard bed and bath arrangement, so an occupant secures the room from inside while staff keep an emergency way in.
    3) Do I have to order the ML2030 handed, or can I flip it in the field?
    Order it either way and re-hand it on site. The patented Quick Reversible latchbolt reverses without opening the lock case, so one lock covers both left and right hand openings. That matters if you're stocking a building: one part number on the shelf instead of two. Note the Dirke (DS) lever is offered as a specific left hand or right hand version, so that trim choice is handed even though the lock body is not.
    4) Can I use a Corbin Russwin ML2030 on a fire rated bathroom door?
    It is UL/cUL listed and UL10C positive pressure rated, good for a 3 hour fire door up to 4 x 10 feet single or 8 x 10 feet pair. It also meets ADA A117.1 and carries California State Fire Marshal and windstorm/hurricane certification. Pair it with a lever rather than a knob to keep the opening ADA compliant.
    5) Will the ML2030 latch into the strike that's already in my frame?
    The latchbolt throws 3/4 inch (19mm) and the deadbolt throws a full 1 inch, with a deadlocking auxiliary latch at 9/16 inch effective throw. It ships with a wrought brass, bronze or stainless ANSI straight lip strike, 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center. If your frame already has a standard ANSI 4-7/8 mortise strike cutout, that box takes it. Anything shallower than the deadbolt's 1 inch throw needs the frame opened up.
    6) I need a privacy mortise lock for a bathroom, but a keyed lock for the office next door. Can I keep them looking the same?
    The ML2030 is the non-keyed privacy function in the ML2000 family, and all twelve functions in the series configure from one ML2054 lockbody with the same trim range. Specify the same lever, rose or escutcheon and the same finish on the keyed function next door and the openings match. On the keyed side, the series accepts new or existing Corbin Russwin key systems and most other manufacturers' cylinders, so a building already keyed to one system stays on it.
    7) What is the closest cross-brand equivalent to the Corbin Russwin ML2030 mortise privacy lock?
    The Cal-Royal NM8440 is the nearest match on function and grade: it is a heavy duty Grade 1 privacy mortise lockset with a deadbolt, listed for 1-3/4 inch doors, the same door thickness the ML2030 is built to. Both are Grade 1 mortise privacy locks for bed and bath openings, so the swap holds at the door prep level. The Hager 3840S is a second Grade 1 privacy mortise lock, with a 2-3/4 inch backset matching the ML2030 backset and a door thickness range of 1-3/4 to 2 inches, which covers thicker doors than the 1-3/4 inch standard.
    8) What mortise privacy lock works on a behavioral health or anti-ligature opening instead of a lever lockset?
    Where a lever cannot be used, TownSteel builds the MRX-L-01, a Grade 1 heavy duty anti-ligature lever mortise lockset in stainless steel for 1-3/4 inch doors, and the MRX-A-01, a ligature resistant arch trim mortise lockset in satin stainless for the same door thickness. Marks USA offers the 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 latch without locking, where the ML2030 provides privacy locking by thumbturn. The ML2030 itself is offered with Behavioral Health BHSS and BLSS trim designs.
    9) The bathroom door does not need to lock at all, just latch. What mortise lock replaces the ML2030 there?
    Drop to a passage function. The Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, and the Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating. Both latch and release from either side with no locking element, where the ML2030 adds a thumbturn that locks the outside grip and a deadbolt operated by thumbturn inside or emergency release tool outside. Hager also builds the 3810S passage mortise lock with rose trim and the 3810E with escutcheon, both on a 2-3/4 inch backset.
    10) Which mortise lock should I use instead of the ML2030 on a door that needs to be keyed?
    The ML2030 is a non-keyed privacy function, so a keyed opening needs a different lock body. For a storeroom opening the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option. For an office or entrance opening the Cal-Royal NM8050 is a Grade 1 office/entrance mortise lockset with auxiliary deadlatch, also 1-3/4 inch. For a classroom the Cal-Royal NM8070 covers the same door prep in Grade 1.
    11) The door is 1-5/8 inch thick. Will the ML2030 fit, or do I need something else?
    The ML2030 is built to a 1-3/4 inch standard door thickness. For thinner stock, the Alarm Lock Trilogy line is listed for 1-5/8 to 1-7/8 inch doors across the DL2700CR classroom lock, the DL3500CR Grade 1 classroom lock with 300 user codes, and the DL4500 Grade 1 electronic mortise deadbolt with 2,000 user codes and privacy keypad. Those are electronic units rather than mechanical thumbturn privacy locks, so confirm the opening can accept a keypad before specifying one.
    12) What looks like an ML2030 substitute but is only a deadbolt or a thumbturn part?
    Several mortise items cover only part of what the ML2030 does. 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; neither carries a latchbolt or grip, so the door will not latch on its own. The Sargent 130KB and 130W are mortise thumbturns only, the trim piece rather than the lock. The ML2030 combines a 3/4 inch latchbolt with a thumbturn-operated deadbolt in one lock case, so replacing it with a deadbolt alone leaves the door without a latch.
    13) What mortise lock fits a residential-style entry door where the ML2030 backset does not work?
    The ML2030 uses a 2-3/4 inch backset. Baldwin builds mortise lock bodies on a 2-1/2 inch backset instead: the 6301 entry/apartment knob by knob and the 6301LS lever by lever, both for doors 1-3/4 inch and over, and the 6310 entry/storeroom knob by knob and the 6310190RRLS right hand reverse lever by lever, both listed for 1-3/4 inch and over doors. The backset difference means the door prep is not interchangeable with the ML2030, so measure from the door edge to the spindle centerline before ordering.
    14) Which mortise lock handles an aluminum storefront or glass door instead of the ML2030?
    The ML2030 is built for a 1-3/4 inch door with a 5-7/8 inch by 4 inch by 15/16 inch steel lock case, which needs a full mortise pocket. Storefront and glass openings take different hardware: the Alarm Lock DL1300NW is a Trilogy Networx wireless electronic mortise lock with keypad made for Adams Rite deadlatches, the Dormakaba 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. Marks USA also builds the 21AC and 22AC ornamental iron mortise locks with round knob for 1 inch doors.
    15) Is a mortise privacy lock overkill for a restroom, or should I use a cylindrical one?
    For a public or institutional restroom taking constant traffic, the mortise is the right call: the ML2030 is ANSI/BHMA A156.13 Series 1000 Grade 1 for both operational and security, with a heavy gauge steel case and a 1 inch stainless deadbolt in the same door prep as the latch. UL cycle tested to 14.5 million cycles. A cylindrical lock like the Schlage PC10 Grade 1 passage is a lighter prep and a simpler install, but it has no deadbolt and no privacy function. If you're cutting a new door and the traffic is residential apartment interior rather than commercial, the cylindrical route saves labour.
    16) What do I have to specify when ordering an ML2030 mortise privacy lockset?
    Three choices beyond the lock itself. Lever design: Armstrong (AS), Citation (CS), Dirke (DS, ordered left or right hand), Essex (ES), Lustra (LS), Newport (NS), Princeton (PS) or Regis (RS). Trim style: A rose at 2-1/4 inch diameter, F rose at 2-7/8 inch, M escutcheon or N escutcheon. Finish: fourteen of them, from 605 bright brass and 626 satin chrome through 630 satin stainless, 613 oil rubbed bronze and BSP black suede powder coat. Escutcheon trim is what carries the optional status indicator if you want locked/unlocked visibility from the corridor.
    17) My doors are 1-5/8 to 1-7/8 inch, not a standard 1-3/4. Will the ML2030 work?
    The ML2030 is built to 1-3/4 inches as standard with optional thicknesses available, so a mixed batch of odd doors is worth confirming per opening rather than assuming. Where you need a stated range that covers 1-5/8 to 1-7/8 inches, the Alarm Lock Trilogy DL2700CR and DL3500CR mortise locks are Grade 1 units listed for that span, though both are electronic classroom function rather than privacy.
    18) Can the ML2030 be wired for access control or card readers?
    No. The ML2030 is a mechanical, non-electronic privacy lock with no wiring provision. Motorized Electric Latch Retraction is offered on the ML20900 series, not here. If a bedroom or bath opening genuinely needs credentialed access, look at an electronic mortise such as the Dormakaba E-Plex E5086 pushbutton and card lock or the TownSteel FME-2000 with RFID, both Grade 1 mortise units.
    19) Do I need to order a cylinder with an ML2030 privacy lock?
    No cylinder needed. The privacy function is non-keyed: it locks by thumbturn from inside and opens from outside with an emergency release tool, so there is nothing to key and nothing to bit. Keyed functions in the ML2000 family take a brass 6-pin L4 keyway cylinder, 0-bitted as standard, but that is a different function than the ML2030.
    20) Does the trim on a Corbin Russwin mortise privacy lock thru-bolt, and how far apart are the trim holes?
    Thru-bolted trim is standard across the ML2000 designs, which holds alignment and adds pull-off resistance versus screw-on rose trim. Center to center spacing is 3-5/8 inches (92mm) from knob or lever to cylinder, and 2-7/16 inches (62mm) from knob or lever to thumbturn. Those two numbers are what you check against an existing door face prep before you commit to a swap.
    21) Is a Schlage CO-100 privacy mortise lock the same thing as an ML2030?
    Both carry a privacy function on a mortise body for a 1-3/4 inch door in Grade 1, but they are different classes of hardware. The Schlage CO-100 is a standalone electronic mortise lock with a keypad reader; the ML2030 is a mechanical, non-electronic lockset whose deadbolt is thrown by thumbturn inside and released from outside by emergency release tool. Choosing the CO-100 means introducing credentials and power to the opening. If the requirement is a mechanical thumbturn privacy lock, the electronic unit is not a substitute.
    22) I need matching trim on a door that takes no working lock. What pairs with an ML2030 opening?
    For a non-functioning leaf, the Schlage L0170 is a Grade 1 non-keyed half dummy mortise lever trim for 1-3/4 inch doors in the L Series, the same door thickness the ML2030 is built to. Emtek builds dummy mortise entrance locksets in several designs, including the 3019 Brisbane in brass, the 3102 Memphis, the 3104 Hamilton and the 3106 Manhattan. Dummy trim does not latch or lock, so it belongs only on the inactive leaf, with the ML2030 carrying the privacy function on the working door.
    23) Can I use a cylindrical lock instead of the ML2030 to simplify the door prep?
    The Schlage PC10 is a Grade 1 non-keyed passage cylindrical lock with rose for 1-3/4 inch doors. It takes a bored prep rather than a mortise pocket, which is a simpler prep on a new door, but it is a passage function with no locking element. The ML2030 is a mortise lock whose thumbturn locks the outside grip and throws a deadbolt. If the door already has a mortise pocket, the cylindrical lock will not cover the existing cutout, and if the opening needs privacy the passage function does not provide it.
    24) What is the difference between the ML2030 privacy function and a dormitory or corridor mortise lock?
    The Sargent 7925 is a Grade 1 heavy duty dormitory exit function mortise lock with rose trim and a single cylinder deadbolt in the 7900 Series, and the Schlage L9092EU with 03A trim is a heavy duty corridor function electric lock/unlock outside lever mortise lock, keyed outside with request to exit, running on 12/24VDC for 1-3/4 inch doors. Both are keyed corridor-type functions intended for suite and dormitory entries. The ML2030 is non-keyed: the deadbolt is thrown by thumbturn inside and released from outside only by emergency release tool, which suits a bath or bedroom door rather than a keyed corridor entry.
    25) Which mortise privacy lock is field reversible without swapping parts for handing?
    The ML2030 uses a patented Quick Reversible latchbolt that re-hands without disassembling the lock case, and is listed as field reversible for hand direction. Among comparable mortise locks, the Falcon MA101 Grade 1 heavy duty passage lock is also field reversible, and the BEST 45H heavy duty public entrance mortise lock body offers field reversible operation. Handing matters when stocking one lock across a floor of doors that swing both ways; a field reversible body means one part number covers both hands.
    26) For an office door that needs a non-keyed lock rather than full privacy, what replaces the ML2030?
    The Hager 3850E is a Grade 1 office function mortise lock with lever and escutcheon, non-keyed, on a 2-3/4 inch backset and listed for 1-3/4 to 2-1/2 inch doors, matching the ML2030 backset. Office function is intended for an occupant to secure the outside lever during working hours, where the ML2030 privacy function locks the outside grip by thumbturn and adds a deadbolt released from outside by emergency tool. On thicker doors, the 3850E range extends past the 1-3/4 inch standard the ML2030 is built to.
    27) Is the Schlage LE Series mortise lock an equivalent to the ML2030 for a privacy opening?
    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 ML2030 is ANSI/BHMA Grade 1 per A156.13 Series 1000 and is a mechanical lockset with no electronics. The Schlage LEMD-GRW is the Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and mobile enabled deadbolt with LED on Greenwich trim, right hand, also 3 hour fire rated. Both Schlage units require credential management; the ML2030 does not.
    28) I need the opening to release electrically. What mortise lock does that where the ML2030 cannot?
    The ML2030 is a mechanical lockset with no electrical option on the lock itself, though the ML20900 series offers Motorized Electric Latch Retraction. For an access-controlled opening, the Command Access ML190 is a heavy-duty motorized storeroom mortise lock with field selectable fail secure and fail safe operation on 24VDC, and the BEST 45HW is a heavy duty wired electromechanical mortise lock running 12V or 24V. Both need power run to the door through a hinge or transfer device, which the ML2030 does not.
    29) Which mortise locks give keyless entry with codes or cards where the ML2030 uses a thumbturn?
    The ML2030 is non-keyed and operates by grip and thumbturn only. For credential-based openings, the Dormakaba E5086 is a Grade 1 E-Plex entry/egress electronic pushbutton and card lock in a back to back mortise configuration, the PowerPlex P2066 is a mortise lock in the PowerPlex 2000 Series, and the LX-I-M002 Saffire is an electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2. Accentra builds the NTM623-NR nexTouch Generation 3 mortise lock with a capacitive touchscreen keypad and cylinder override, with no deadbolt. BEST also offers the 45HZ EZ Series electronic keypad mortise lock with key override.
    30) What material and finish should I pick for an ML2030 in a coastal or high humidity building?
    Trim substrate is brass or bronze, and the armored front and strike come in wrought brass, bronze or stainless steel. For wet or coastal work, 630 satin stainless steel or 629 bright stainless are the finishes that hold up best to moisture and cleaning chemicals in a restroom. If you're matching existing hardware instead, 626 satin chrome and 613 oil rubbed bronze are the two most common commercial matches.
    31) The latch on our old mortise locks drags when the door closes. Does the ML2030 fix that?
    The two piece latchbolt carries an anti friction insert that cuts the force needed to close, which is the usual cure for a door that scuffs or won't latch cleanly against a stiff closer. Latch face is 5/8 x 1 inch with a 3/4 inch throw, and the auxiliary latchbolt deadlocks the main latch at 9/16 inch effective throw so the bolt can't be carded back.
    32) What is a lighter-duty mortise latch option than the ML2030 for an interior door?
    The Codelocks CL2255 is a medium duty electronic tubular mortise latch in the CL2000 Series with a brushed steel finish. The ML2030 is a Grade 1 commercial lockset with a heavy-gauge steel case and a 1 inch stainless steel deadbolt, tested to 14.5 million cycles. Duty level is the deciding factor: a medium duty latch suits a low-traffic interior door, while the ML2030 is specified for commercial and institutional traffic. Confirm the door already has, or can take, the correct prep before switching between the two.
