Corbin Russwin ML2075LSM626LC – Frequently Asked Questions

1) What does the office entry function on the Corbin Russwin ML2075 actually do at the door?
Office entry is the function most people want on a private office or suite door. The outside lever is locked or unlocked by key from outside or by the inside thumbturn, and the inside lever always retracts the latch for free egress. The ML2075 also carries a separate 1 inch stainless steel deadbolt with a 1 inch throw, thrown by key outside or thumbturn inside, so you can deadlock the opening when the space is empty.
2) Will the ML2075 mortise lock fit my existing 2-3/4 inch backset mortise pocket?
Yes, if the pocket is cut for a standard ANSI mortise lock. The ML2075 uses a 2-3/4 inch backset with a lockcase measuring 5-7/8 x 4 x 15/16 inches and an 8 x 1-1/4 inch armored front. Cylinder is 3-5/8 inch center to center from the lever, and the thumbturn sits 2-7/16 inches from the lever, so your existing face bores need to match those spacings or the door needs to be re-prepped.
3) What door thickness does the Corbin Russwin ML2075 come set up for?
Standard build is 1-3/4 inch (44mm), which is the usual commercial door thickness. Thicker doors are available as an option but have to be specified at order time, not adjusted in the field.
4) Do I have to order the ML2075 handed, or can I flip it on site?
Order it and hand it in the field. The ML2075 uses Corbin Russwin's patented Quick Reversible latchbolt, so you re-hand it without opening the lock case. That is useful for a property manager stocking spares across a building with both left and right hand openings.
5) The ML2075 ships less cylinder - what cylinder do I need to buy with it?
You supply the mortise cylinder. It will take a new or existing Corbin Russwin key system, and it also accepts cylinders from most other manufacturers, so an existing masterkey system on another brand can usually carry over. Corbin Russwin's own standard cylinder for the series is brass, 6-pin, L4 keyway, 0-bitted. Corbin Russwin patented high security Pyramid and Access 3 cylinders are the option where key control matters.
6) Can the ML2075 go on a fire rated office door?
Yes. The lock is UL and cUL listed with UL10C positive pressure, rated for 3 hour fire doors up to 4 by 10 feet single or 8 by 10 feet pair. It is also ANSI/BHMA A156.13 Series 1000 Grade 1 for both operational and security, and meets ADA A117.1, plus California State Fire Marshal and windstorm/hurricane certification.
7) Will the ML2075 latch into the strike already in my frame?
It depends what is in there. The latchbolt is a two-piece anti-friction design measuring 5/8 x 1 inch with a 3/4 inch (19mm) throw, and the auxiliary deadlatch gives 9/16 inch effective throw. The strike supplied 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 it will drop in; a smaller T-strike or a non-ANSI prep means reworking the frame. Remember the 1 inch deadbolt needs its own pocket depth behind the strike.
8) I need a mortise lock for the same door but it has to stay locked at all times from outside - what should I use instead of the ML2075?
The ML2075 is an office entry function, which lets staff leave the outside lever unlocked during business hours. If the opening must stay secured at all times with key-only entry, a storeroom function is the right call: the Accentra 8805FL is a Grade 1 storeroom mortise lock from the 8800 Series with the Arcadia lever, and the Cal-Royal NM8080 is a heavy duty Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option. Both use the same mortise pocket prep class as the ML2075.
9) The opening needs the outside lever controlled by the access control panel - what replaces the ML2075?
Move to an electrified mortise lock. 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, and the Command Access ML190 is a heavy-duty motorized mortise lock in storeroom function with field selectable EL/EU operation on 24VDC. The ML2075 is mechanical only.
10) Does the Baldwin 6301 mortise lock body drop into the same prep as the ML2075?
No. The Baldwin 6301 entrance/apartment mortise lock body, offered knob by knob and lever by lever, is built on a 2-1/2 inch backset for doors 1-3/4 inch and over. The Corbin Russwin ML2075 uses a 2-3/4 inch backset, so the cross-bore and lever centerline will not line up with an existing Baldwin 6301 prep without rework.
11) Is a mortise lock like the ML2075 worth it over a cylindrical lockset on an office door?
On a commercial office door with real traffic, yes. A mortise lock puts the whole mechanism inside the door edge, which is why the ML2075 can carry a 1 inch stainless deadbolt and a separate latch in one case, and it is UL cycle tested to 14.5 million cycles. A cylindrical lock such as the Schlage PC10 Grade 1 passage is quicker to prep and cheaper to replace, but it cannot give you a deadbolt in the same body. Pick mortise where you want key plus deadbolt plus long cycle life on one opening.
12) I need the same lock body but in classroom or storeroom function - what are my options?
The ML2000 lock body is multi-function: 12 functions can be configured from a single ML2054 lockbody, so a locksmith holding that body can set up office, classroom or other functions. If you would rather buy the function outright from another line, the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset and the NM8080 is the Grade 1 storeroom version, both for 1-3/4 inch doors; the Accentra 8805FL is a Grade 1 storeroom mortise with Arcadia lever.
13) Can I get an ML2075 with electric latch retraction or an access control reader?
No. The ML2075 is a mechanical lock with no electronics. Motorized Electric Latch Retraction is offered on the Corbin Russwin ML20900 series instead. If you want a credentialed opening, the Schlage LEMD-GRW is a Grade 1 wireless mortise lock with a 125kHz proximity reader, and the TownSteel FME-2000 is a Grade 1 RFID mortise lockset for 1-3/4 inch doors.
14) What lever and finish does the ML2075 come with, and will it match my other doors?
It is built with the Lustra wrought lever on an M escutcheon in 626 satin chrome, which is the most common commercial finish and will sit alongside most existing satin chrome trim. The ML2000 series trim range is wider than that, including Museo, Vineyard and the Behavioral Health BHSS/BLSS designs, plus status indicator trim in sectional and escutcheon. Underlying substrate is brass or bronze.
15) Is this lock tough enough for a high abuse or vandalism-prone entry?
The base ML2075 has a heavy gauge steel case and thru-bolted trim for alignment and added security. For genuinely high risk openings, the ML2000VR vandal resistant version uses stainless steel escutcheons with tapered edges and Torx pin tamper-resistant screws, and pairs with Corbin Russwin Pyramid or Access 3 high security cylinders. If the concern is patient or resident self-harm rather than vandalism, look at a ligature resistant mortise instead, such as the TownSteel MRX-L-01 stainless Grade 1 anti-ligature lever lockset.
16) Is the Hager 3850E office mortise lock a substitute for the Corbin Russwin ML2075?
Only for a non-keyed opening. The Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon on a 2-3/4 inch backset, but it is non-keyed and fits doors 1-3/4 to 2-1/2 inches thick. The ML2075 is a single cylinder office entry lock that ships less cylinder and accepts Corbin Russwin key systems as well as most other manufacturers' cylinders, so it is the choice where the outside lever must be key controlled. Both share the 2-3/4 inch backset, so the door prep is comparable.
17) Can I use the Schlage PM010 in place of the ML2075 to save on the opening?
Only on a door that never needs to lock. 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 heavy duty Grade 1 fire rated mortise passage lock with field reversible operation. Neither has a cylinder or deadbolt. The ML2075 is a single cylinder office entry lock with a 1 inch stainless steel deadbolt and 1 inch throw, so it is the one to keep where the room has to be secured at the end of the day.
18) What looks like an ML2075 alternative but will not actually work in the same mortise pocket?
Several mortise-family items are not interchangeable with it. Sargent 130KB and 130W are mortise thumbturns only, not lock bodies. Schlage L0170 is half dummy trim in the L Series with no latch at all, and Emtek's Brisbane 3019, Memphis 3102, Hamilton 3104 and Manhattan 3106 mortise entrance locksets are dummy function. The Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset with no latch or lever. The ML2075 combines a keyed office entry latch and deadbolt in one 5-7/8 by 4 by 15/16 inch heavy-gauge steel case.
19) If I want keypad or credential access on this opening instead of a keyed office entry lock, what mortise options are there?
The ML2075 is a mechanical, non-electronic lock. For electronic control in a mortise prep, the Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with 300 user codes in classroom function for 1-5/8 to 1-7/8 inch doors, the Schlage CO-100 is a Grade 1 heavy duty standalone electronic mortise lock with keypad reader in privacy function for 1-3/4 inch doors, and the TownSteel FME-2000 is a Grade 1 heavy duty RFID mortise lockset in classroom function for 1-3/4 inch doors. Note the function differences before swapping.
20) For a behavioral health or ligature-sensitive room, is the ML2075 the right mortise lock?
For a patient room where ligature resistance drives the spec, look at a dedicated anti-ligature mortise set. The TownSteel 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, the MRX-A-01 is the same passage function with satin stainless ligature resistant arch trim, and the Marks USA 5PDN is a Grade 1 ligature resistant, ADA compliant hospital passage push/pull paddleset in satin stainless steel. The ML2075 is a keyed office entry lock and is offered with Behavioral Health BHSS/BLSS trim within the ML2000 Series where a keyed function is required.
21) Our dorm corridor doors need a mortise lock - is the ML2075 office entry the right function or is there a better fit?
For a dormitory corridor, the Sargent 7925 is the closer function: a Grade 1 heavy duty corridor/dormitory exit function mortise lock from the 7900 Series with rose trim and a single cylinder deadbolt. The Corbin Russwin ML2075 is an office entry function with a single cylinder and a 1 inch stainless steel deadbolt, which suits tenant and staff offices where the outside lever is unlocked during the day rather than a resident corridor door.
22) We need a privacy function on restroom and exam doors, not the ML2075 - what mortise locks cover that?
The Cal-Royal NM8440 is a heavy duty Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors, and the Hager 3840S is a Grade 1 privacy mortise lock on a 2-3/4 inch backset for doors 1-3/4 to 2 inches thick, matching the 2-3/4 inch backset the ML2075 uses. The ML2075 is keyed office entry, so it is not intended for a restroom or exam room where occupants lock from inside without a key.
23) Can I order just a lock body like the BEST 45H instead of the complete ML2075?
They are sold differently. The BEST 45H is a heavy duty mortise lock body in public entrance function with field reversible operation, and the 45HCA is a heavy duty mortise lockbody with intruder function - lock bodies without trim. The Corbin Russwin ML2075 ships as a complete office entry lock with the Lustra lever and M escutcheon in 626 satin chrome, less cylinder, and is field reversible using the patented Quick Reversible latchbolt that re-hands without opening the case.
