Corbin Russwin 670F73-626 – Frequently Asked Questions

1) Will the Corbin Russwin 670F73 outside lever fit a 1-3/4 inch door?
That is exactly what it is built for. The 670F73 outside lever and spindle assembly is machined for 1-3/4 inch (44mm) doors, which is the standard commercial thickness. The spindle length is what sets that, so on a thicker or thinner leaf you need the ML2000 trim assembly cut for that thickness instead of this one. Confirm the door thickness at the lock edge before ordering, not at the frame.
2) Is the 670F73 lever handed, or can I use it on either a left or right hand door?
Either. The 670F73 is field reversible, so one part covers both hands and you do not have to stock a left and a right version for a corridor full of doors. The ML2000 lockbody it mounts to uses a quick reversible latchbolt that re-hands without taking the lock case apart, so a hand change on site is a trim-off, flip, trim-on job.
3) I only need to replace a broken lever on a Corbin Russwin mortise lock, not the whole lockset. Is this the right part?
Yes, if the lock is an ML2000 Series mortise. The 670F73 is the outside lever and spindle only, a replacement trim component, so the lock case stays in the door and your keying and function are untouched. It is the cast AS lever style. If your existing lever is a different design family, you will not get a visual match from this part, and if the failure is in the lock case itself (latch not retracting, deadbolt binding) replacing the lever will not fix it.
4) Does the ML2000 mortise lock fit a 2-3/4 inch backset door prep?
Yes. The ML2000 Series is a 2-3/4 inch (70mm) backset mortise, which is the standard commercial mortise prep, so the 670F73 lever lands where the existing hole is. Center to center, the lever to cylinder spacing is 3-5/8 inches (92mm) and lever to thumbturn is 2-7/16 inches (62mm). If your door is prepped to those dimensions, the trim covers the existing holes.
5) Will a Corbin Russwin ML2000 latch into the strike already in my frame?
It depends on the throw your existing strike was cut for. The ML2000 uses a two-piece anti-friction latchbolt with a 3/4 inch (19mm) throw, a 9/16 inch (14mm) deadlocking auxiliary latch, and a one-piece stainless deadbolt with a 1 inch (25mm) throw. The supplied strike is an ANSI straight lip, 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center. An existing ANSI 4-7/8 inch strike box with adequate depth for a 1 inch deadbolt will take it; a shallow residential strike will not.
6) Is the Corbin Russwin ML2000 approved for a fire rated door, and what grade is it?
ANSI/BHMA A156.13 Series 1000, Operational and Security Grade 1, and 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. It also carries ADA A117.1 and California State Fire Marshal listings. For an institutional spec calling out Grade 1 mortise with a 3-hour rating, that is the set of approvals the ML2000 platform holds.
7) What does the Corridor/Dormitory function on a Corbin Russwin ML2000 lock actually do?
Corridor/Dormitory is the classroom-corridor style function used on student housing and corridor openings: the outside lever is locked or unlocked by key, the inside lever always retracts the latch for free egress, and the deadbolt throws separately. The 670F73 supplies the outside lever and spindle for that arrangement. The lockbody behind it (ML2054) is multi-function, with 12 functions configurable from the one case, so the function lives in the lock, not in this lever.
8) Can I get the ML2000 outside lever in satin chrome or oil-rubbed bronze to match the rest of my building?
Both, plus twelve more. The 670F73 lever and spindle comes in 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 a property manager matching existing openings, 626 and 630 are the usual commercial pairings and 613 or 613E the usual living-finish bronzes.
9) Can I keep my existing cylinders and keyway when I work on a Corbin Russwin ML2000 mortise lock?
Usually yes. The ML2000 works with new or existing Corbin Russwin key systems and accepts most other manufacturers' cylinders, so a locksmith standardizing a building does not have to rekey the whole floor. The factory cylinder is brass, 6-pin, L4 keyway, shipped 0-bitted. The 670F73 is lever and spindle only, so it does not change cylinder or keying either way.
10) Is a mortise lock the right choice for a dorm corridor, or should I use a cylindrical lever?
For a dorm or corridor opening under constant traffic, a mortise is the heavier answer: the ML2000 puts a heavy-gauge steel case, 5-7/8 x 4 x 15/16 inches, inside the door edge, carries a 1 inch stainless deadbolt alongside the latch, and is thru-bolted at the trim for alignment and pull resistance. A cylindrical lever is faster to install and cheaper to prep, but it gives you no separate deadbolt and puts all the load on the door face. The trade-off is the prep: a mortise pocket has to be routed, so retrofitting a cylindrical opening to mortise is real millwork.
11) How many cycles is the Corbin Russwin ML2000 tested to?
14.5 million cycles, UL verified (Verification ID V875753). For a high-traffic institutional opening, a stairwell or a dorm corridor, that is the number that matters more than the finish, and it is well past the Grade 1 operational minimum the ML2000 is certified to under A156.13.
12) Does the Corbin Russwin ML2000 come in an electrified version for access control?
Yes, through the ML20900 series, which offers Motorized Electric Latch Retraction (MELR) for openings tied to a card reader or remote release. Status indicator options for locked and unlocked visibility are also available on sectional and escutcheon trim. Those are lockbody and trim-level options, so if you need them, specify the electrified lockbody rather than adding them to a mechanical lever assembly like the 670F73.
