Corbin Russwin 670F30 626 – Frequently Asked Questions

1) Will the Corbin Russwin 670F30 lever fit any mortise lock, or only the ML2000 Series?
The 670F30 Cast CS Citation lever is a replacement trim part for the Corbin Russwin ML2000 Series mortise lock only. It is the inside lever, so it swaps onto an existing ML2000 lockbody without touching the lock case. If your lockset is another series or another brand's mortise lock, this lever is not the part.
2) What door thickness does the Corbin Russwin 670F30 ML2000 lever work on?
Standard fit is a 1-3/4 inch (44mm) door, which is the ML2000's standard door thickness and the usual commercial door. Optional thicknesses are available on the series. If you are replacing a lever on an existing ML2000 lockset the thickness is already settled by the lock that is in the door.
3) Is the 670F30 Citation lever handed, or can I use one part on both left and right hand doors?
Field reversible. The 670F30 lever handing can be changed on the job, and the ML2000 lockbody it mounts to uses a quick reversible latchbolt that re-hands without disassembling the lock case. For a property manager stocking spares, that means one lever part number covers both hands across the building.
4) Does replacing just the inside lever on an ML2000 mortise lock keep the Grade 1 and fire rating intact?
Using the factory 670F30 Citation lever keeps the lockset as built. The ML2000 mortise lock is ANSI/BHMA A156.13 Series 1000, Operational and Security Grade 1, and it is UL/cUL listed to UL10C positive pressure for 3-hour fire doors up to 4 x 10 feet single or 8 x 10 feet pair. Swapping in an off-brand lever is what puts that listing in question, not a like-for-like factory trim replacement.
5) I only need the inside lever on a corridor lock, not the whole lockset. Is the 670F30 the right part?
That is exactly what it is. The 670F30 is the inside lever alone for an ML2000 corridor/dormitory function lock, so a worn or broken inside handle can be replaced without pulling the lock case, redoing the door prep, or rekeying the cylinder. Outside trim, cylinder and lockbody stay in place.
6) Which finishes does the Corbin Russwin 670F30 Citation lever come in?
Thirteen finishes, so you can match what is already hanging on the other doors: 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, and 722 black oxidized bronze oil-rubbed. On a repair, order the BHMA number stamped on the existing trim rather than matching by eye, since 612, 613 and 722 read very close in a corridor.
7) What backset and lock case size does the ML2000 mortise lock this lever fits use?
The ML2000 is a 2-3/4 inch (70mm) backset mortise lock with a heavy-gauge steel case measuring 5-7/8 x 4 x 15/16 inches, and an 8 x 1-1/4 inch armored front. Those numbers matter when you are checking that the pocket already cut in the door matches before you order trim for it. Center to center, lever to cylinder is 3-5/8 inches, and lever to thumbturn is 2-7/16 inches.
8) Is a lever like the Citation CS required for ADA compliance instead of a knob?
A lever handle is the operable hardware that satisfies the no-tight-grasping, no-twisting requirement, and the ML2000 series the 670F30 mounts to is stated as meeting ADA A117.1. For dormitory, healthcare and education work where knob trim is being retired, the Citation cast lever is a direct trim swap on an ML2000 that is already in the door.
9) Will the ML2000 corridor lock this Citation lever fits latch into my existing ANSI strike?
The latchbolt is a two-piece anti-friction design measuring 5/8 x 1 inch with a 3/4 inch (19mm) throw, and it is supplied against an ANSI straight lip strike of 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center. If the frame already has a standard 4-7/8 inch ANSI strike prep, the geometry lines up. The stainless deadbolt throws 1 inch and the deadlocking auxiliary latch has a 9/16 inch effective throw, so verify strike pocket depth on any older non-ANSI frame.
10) Can I keep my existing keys and cylinders if I am rebuilding a Corbin Russwin ML2000 lock?
Yes on both counts. The ML2000 works with new or existing Corbin Russwin key systems and accepts most other manufacturers' cylinders; the standard cylinder is brass, 6-pin, L4 keyway, supplied 0-bitted. Replacing the inside lever with the 670F30 does not touch keying at all, since the cylinder lives in the outside trim.
11) Do I have to order a different lockbody for each ML2000 function in my building?
No. One ML2054 lockbody configures to 12 functions, so a facility can stock a single lock case and set it for the opening in front of you. Trim like the 670F30 Citation lever is ordered separately by design and finish, which is what lets you standardize the box and vary only the handle.
12) What other ML2000 trim options exist besides the cast Citation lever?
The series carries several trim families: Museo, Vineyard, and Behavioral Health trim (BHSS/BLSS) for psychiatric and ligature-resistant openings, plus status indicator trim showing locked or unlocked on sectional and escutcheon designs. If the opening is a patient room or a detention-adjacent space, the Behavioral Health trim is the correct choice rather than a standard cast lever like the Citation.
13) How many cycles is the Corbin Russwin ML2000 mortise lock tested to?
14.5 million cycles under UL testing, verification ID V875753. On a dormitory corridor or a healthcare main run where a door gets hit a few hundred times a day, that is the number an MRO buyer standardizes on, and it is why the trim is cast rather than pressed.
14) Is there an electrified version of the ML2000 mortise lock for access control?
Motorized Electric Latch Retraction (MELR) is offered on the ML20900 series. That is a different lockbody order, not a trim change, so a Citation lever alone will not electrify an opening. Specify the ML20900 with MELR up front when the door is going on access control.
