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

1) Does the Corbin Russwin ML2068 mortise lockbody come with levers, knobs, or trim?
No. The ML2068 is the lock case only, so you order trim separately: lever or knob, roses or escutcheons, and the thumbturn and emergency release the privacy function needs on the two faces. The case itself is heavy-gauge steel at 5-7/8 x 4 x 15/16 inches with an 8 x 1-1/4 inch armored front. Corbin Russwin trim families that mount to it include Museo, Vineyard, and the Behavioral Health BHSS and BLSS designs, plus the ML2000VR vandal resistant escutcheons with tapered edges and Torx pin tamper-resistant screws. Trim spacing is fixed by the case: 3-5/8 inches center to center from knob or lever to cylinder, and 2-7/16 inches from knob or lever to thumbturn.
2) Will the ML2068 privacy mortise lock work on a 1-3/8 inch door?
Not as standard. The ML2068 is built for 1-3/4 inch (44mm) doors, which is the normal commercial thickness; other thicknesses are an option that has to be specified when the lock is ordered, not something you adjust in the field. If the opening is an older 1-3/8 inch interior door, confirm the thickness before ordering rather than assuming the standard case will make up the difference.
3) Is the ML2068 mortise lockbody handed, and can I re-hand it on the job?
It is handed, but you can reverse it on site. The patented Quick Reversible latchbolt lets you change hand without opening the lock case, so one lockbody covers left and right hand openings and a stocked spare fits whichever door fails first. That is the practical reason to keep this one on the truck instead of two part numbers.
4) What does the ML2068 privacy function actually do on an apartment or restroom door?
It is a privacy/apartment function: a thumbturn inside throws a 1 inch stainless steel deadbolt to secure the room, with an emergency release on the outside for staff access. The 3/4 inch latchbolt keeps the door closed and is retracted by the lever or knob on either side. Because the deadbolt is in the same case, you get the latching and the deadlocking in one door prep, so no separate deadlock is mortised above the lock.
5) Will the ML2068 latch into the strike already in my frame?
It depends on the strike you have. The lock is cut for a 2-3/4 inch backset with a 3/4 inch (19mm) throw two-piece anti-friction latchbolt, plus a 9/16 inch effective throw deadlocking auxiliary latch, and the deadbolt projects 1 inch. The matching strike is an ANSI straight lip, 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center. If the frame already carries a standard ANSI 4-7/8 inch mortise strike with a deep enough pocket for a 1 inch bolt, the lock drops into it. A strike cut only for a latch, with no deadbolt pocket, will not take this lock.
6) Can I use the ML2068 on a fire rated apartment or patient room door?
Yes. The ML2068 is UL and cUL listed to UL10C positive pressure and carries a 3-hour rating up to a 4 by 10 foot single door or an 8 by 10 foot pair. It also meets ANSI/BHMA A156.13 Series 1000 at Grade 1 for both operational and security, ADA A117.1, California State Fire Marshal, and windstorm/hurricane certification. For a healthcare or multi-family spec that calls out a Grade 1 fire rated mortise lock, this meets it.
7) Can I replace just the lock case in an existing Corbin Russwin ML2000 mortise pocket without redoing the door?
That is what the ML2068 is for. It is the lockbody alone, sized 5-7/8 x 4 x 15/16 inches on a 2-3/4 inch backset with the standard 8 x 1-1/4 inch armored front, so it goes back into an ML2000 series pocket and reuses the existing trim and strike. Swapping to the ML2068 also changes the door to a privacy/apartment function, so make sure the trim on the door has a thumbturn and an emergency release, not a keyed cylinder.
8) What is the closest equivalent to the Corbin Russwin ML2068 mortise lockbody from another manufacturer?
The nearest cross-brand match is the Accentra 8800FL Series mortise lock body, which is also ANSI/BHMA Grade 1 and, like the ML2068, ships with field reversible handing so the hand can be set at the opening rather than specified at order. The ML2068 is a lockbody only in the Corbin Russwin ML2000 Series, Grade 1, privacy/apartment function, non-keyed, for 1-3/4 inch doors. If a job is standardized on Corbin Russwin trim and key systems, the ML2068 keeps that standard; if the building is already on Accentra, the 8800FL body matches the same grade and handing flexibility.
9) If I am replacing a Grade 1 mortise lock body and do not know the hand of the door yet, which one should I order?
Either the Corbin Russwin ML2068 or the Accentra 8800FL Series body will cover you, because both are field reversible - the handing is set during installation instead of being locked in at the time of order. That matters on retrofit work where a crew is pulling bodies out of doors of mixed hand across a building and wants one line item on the purchase order. The ML2068 covers the privacy/apartment function specifically and is non-keyed, so confirm the openings you are stocking for are bed, bath, or apartment privacy doors rather than keyed entries before consolidating on it.
10) Does an Accentra 8800FL mortise lock body drop into a door prepped for a Corbin Russwin ML2068 without new trim?
Treat them as separate systems rather than interchangeable halves. Both are Grade 1 mortise lock bodies with field reversible handing, but a lock body is only the case that mortises into the door - the levers, escutcheons, roses, and cylinder are trim that belongs to its own manufacturer's series. The ML2068 is built for Corbin Russwin ML2000 Series trim and for use with new or existing Corbin Russwin key systems. Swapping in a different brand's body means sourcing that brand's trim to match, so on a repair where the existing Corbin Russwin trim is staying on the door, order the ML2068 body.
11) Do I need a cylinder or key for the ML2068 mortise lock?
No key is involved. The ML2068 is a non-keyed function, so there is no cylinder to buy and no keyway decision to make. If the door needs to be keyed instead of thumbturn operated, this is the wrong lock function and you want a keyed member of the ML2000 family. Note that other ML2000 lockbodies do take cylinders and will work with new or existing Corbin Russwin key systems, and accept most other manufacturers' cylinders.
12) How does the ML2068 hold up in a high traffic building like a school or hotel?
It is built for that duty. The case is heavy-gauge steel, the deadbolt one-piece stainless, and the lock has been UL cycle tested to 14.5 million cycles (Verification ID V875753), well past the Grade 1 requirement. The two-piece latchbolt with an anti-friction insert also takes less force to close, which matters on doors with strong closers and on residents who do not pull the door properly. For high-abuse or high-risk areas, the ML2000VR vandal resistant stainless escutcheons with tamper-resistant Torx pin screws are the trim to pair with it.
13) Is there a field reversible Grade 1 mortise lock body from another brand instead of the Corbin Russwin ML2068?
The Accentra 8800FL Series mortise lock body is the closest cross-brand equivalent we carry, also Grade 1 and also field reversible for handing. It is a lock body only in the same way, so trim is separate either way. Which one you pick usually comes down to what is already hanging in the building: mortise trim and cylinders are not interchangeable between the two lines, so a property standardized on Corbin Russwin ML2000 trim should stay with the ML2068.
14) Is the ML2068 an electrified lock, and can I get electric latch retraction on this function?
No, the ML2068 is a straight mechanical lock with no electrical component. Motorized Electric Latch Retraction is offered on the ML20900 series within the same family, so an opening that has to release on an access control signal needs one of those rather than this lockbody.
15) What finishes does the ML2068 mortise lockbody come in?
Fourteen, and they matter mainly for the armored front, since the case body is buried in the door. The list runs 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. If you are matching existing openings in a building, pick the code that is already on the trim so the exposed front does not read off.
