Corbin Russwin 670F36 626 – Frequently Asked Questions

1) Is the Corbin Russwin 670F36 a complete mortise lock or just the lever?
The 670F36 is the inside lever trim only, a cast NS-style lever sold as a replacement part for ML2000 Series mortise locks. It is not a lockset. If your lock body is worn out or you need a complete opening, you need an ML2000 mortise lock; the 670F36 is what you order when the lever itself is broken, bent, or being changed out on an otherwise good lock.
2) Do I have to order a left-hand or right-hand Corbin Russwin 670F36 lever?
No hand to specify. The 670F36 NS lever is field reversible, so one part covers both hands and you set the direction at install. The ML2000 lock case it goes on uses a quick-reversible latchbolt that re-hands without taking the case apart, so a hand change at the opening does not mean a new lever or a new lock.
3) Will the 670F36 NS lever fit a 1-3/4 inch commercial door?
Yes. The 670F36 is set up for 1-3/4 inch (44mm) door thickness, which is the standard commercial door. The ML2000 lock it trims is a 2-3/4 inch (70mm) backset mortise lock, so if your existing prep is a standard ANSI mortise pocket at that backset, the lever lands where the old one did.
4) Can I replace just the inside lever on a corridor or dorm lock without pulling the whole mortise lock out of the door?
That is exactly what the 670F36 is for. It is the interior-side lever on an ML2000 corridor/dormitory function lock, so a bent or broken inside lever is a trim swap, not a lock replacement. The lock case, latch, cylinder and keying stay in the door and the keying is untouched. On dormitory and student housing turnover, this is the part that gets consumed, not the lock body.
5) Does the 670F36 lever keep my fire-rated opening compliant?
The ML2000 mortise lock it trims is UL/cUL listed to UL10C positive pressure, rated for 3-hour fire doors up to 4' x 10' single or 8' x 10' pair, and the lock is ANSI/BHMA A156.13 Series 1000 Grade 1 for both operational and security. It also meets ADA A117.1. Replacing a damaged lever with the manufacturer's own NS trim keeps the assembly as listed; a generic lever does not.
6) I need to match the levers on the rest of my building. What finishes does the Corbin Russwin 670F36 come in?
Thirteen finishes, which covers most standardization jobs: 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. For a fleet of doors, order by the BHMA number stamped on your existing trim rather than by the finish name; 626 and 630 look similar at a glance but are not the same.
7) Will an ML2000 lock with this lever latch into the strike that is already in my frame?
The ML2000 latchbolt is a two-piece anti-friction unit with a 3/4 inch (19mm) throw, backed by a deadlocking auxiliary latch at 9/16 inch (14mm) effective throw, and the deadbolt is one-piece stainless at 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. If your frame already carries a standard 4-7/8 inch ANSI mortise strike, the latch lines up; if the old strike is a T-strike or a non-ANSI lip, plan on replacing it.
8) How do I know a lever will clear the cylinder on my ML2000 mortise lock?
Spacing on the ML2000 is fixed: 3-5/8 inches (92mm) center to center from lever to cylinder, and 2-7/16 inches (62mm) from lever to thumbturn. Those numbers do not change with the trim you pick, so a 670F36 NS lever drops onto the same escutcheon or sectional prep your current trim uses. If you are cutting a new door, prep to those spacings and the 5-7/8 x 4 x 15/16 inch lock case pocket.
9) Can I keep my existing keys and cylinders when I rebuild a Corbin Russwin ML2000 lock?
Yes. ML2000 locks work with new or existing Corbin Russwin key systems and accept most other manufacturers' cylinders, so a rebuild that includes a new 670F36 lever does not force a rekey. The factory cylinder is brass, 6-pin L4 keyway, 0-bitted as standard, meaning it ships unkeyed for a locksmith to pin to your system. Since the 670F36 is inside-lever trim, it has no cylinder of its own and does not affect keying at all.
10) My ML2000 lock needs a different function. Do I have to buy a new lock or can I change it?
One ML2054 lock body configures to 12 different functions, so a function change on an existing ML2000 opening is often a configuration and trim question rather than a new lock. Where the change calls for different trim on the inside, the 670F36 NS lever is the cast inside-lever option. Also worth knowing before you order: status indicator trim for locked/unlocked visibility is available on sectional and escutcheon trim, and Motorized Electric Latch Retraction is offered on the ML20900 series if the opening is going to access control.
11) Is a cast lever like the 670F36 durable enough for a high-traffic school or hospital corridor?
It is cast rather than pressed, on a lock family that is ANSI/BHMA Grade 1 for operational and security and cycle tested to 14.5 million cycles under UL verification. That is the level specified for commercial corridor traffic, and this trim is catalogued for commercial use only, not residential. In a dorm or clinic corridor where levers get leaned on and hung from, cast trim is the part that survives.
