Corbin Russwin ML2010-NSA-626-M31 – Frequently Asked Questions

1) Is the Corbin Russwin ML2010-M31 a complete mortise lock or just the lever trim?
Trim only. The ML2010-M31 is the lever and escutcheon trim for an ML2000 Series mortise passage lock, not the lock case. If the mortise body is already in the door and you're replacing worn or damaged levers, this is the right part. If the door has no mortise lock in it yet, you need the complete ML2010 passage lockset, because the trim alone has nothing to mount to.
2) What does ANSI function F01 passage mean on a Corbin Russwin ML2010 mortise lock?
F01 is passage/hall/closet: the latchbolt operates by the lever from either side and both levers are always free. There is no key, no cylinder, no locking of any kind. Use it on corridor doors, closets, and openings that only need a latch to hold the door shut. If you need the door to lock, F01 is the wrong function and you want a different ML2000 function, such as an office or classroom lock.
3) Will the Corbin Russwin ML2010 trim fit a 1-3/4 inch door?
Yes, 1-3/4 inches (44mm) is the standard thickness this trim is built for, which is the normal commercial door. Thicker doors are handled through optional thickness configurations on the ML2000 Series rather than the standard part, so a 2 inch or heavier door needs that option called out on the order.
4) Do I have to order the ML2010 lever trim handed, or can I reverse it in the field?
Field reversible. The ML2000 Series uses a patented quick reversible latchbolt that re-hands without taking the lock case apart, so one part covers left and right hand openings. The one exception is the lever itself: the Dirke (DS) design is ordered as a specific left hand or right hand lever, so that style has to be matched to the door.
5) Will the ML2010 latch into the strike already in my frame?
The ML2000 latchbolt is a two-piece anti-friction design with a 3/4 inch (19mm) throw, running into an ANSI straight lip strike measuring 4-7/8 x 1-1/4 inches with a 1-1/8 inch lip to center, and the backset is 2-3/4 inches. If your frame is already prepped for an ANSI mortise strike at that 2-3/4 inch backset, it lines up. A frame cut for a 2-3/8 inch bored-lock backset or a T-strike will not, and that is a frame prep change, not a trim change.
6) Can a Corbin Russwin ML2010 passage lock go on a fire rated door?
Yes. The ML2000 Series is UL/cUL listed to UL10C positive pressure with a 3-hour fire door rating, good up to a 4 x 10 foot single door or an 8 x 10 foot pair. Passage function is fire-door acceptable because the latch stays engaged and both levers always release it, so egress is never obstructed.
7) Does the ML2010 passage trim take a cylinder or a key?
No cylinder and no key. Passage function has no keyed element, so there's nothing to pin, key, or add to a master system. Anyone specifying keying for this opening has the wrong function code and should move to a keyed ML2000 function instead.
8) What is the difference between the A rose, F rose, M escutcheon, and N escutcheon on Corbin Russwin ML2000 trim?
Four trim shapes, and the choice is mostly about covering what's already in the door. The A rose is a 2-1/4 inch round plate, the F rose is a larger 2-7/8 inch round plate, and the M and N escutcheons are full-length plates. Go with a rose for a clean modern look on a fresh prep. Go with the larger F rose or an escutcheon when you're covering older prep marks, scuffing, or a previous trim's footprint on a retrofit. Escutcheon trim is also what carries the ML2000 status indicator option on functions that offer it.
9) Can I match Corbin Russwin ML2010 lever trim to the finishes on the rest of my building?
Fourteen finishes cover it: 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 standardizing a portfolio, 626 satin chrome and 630 satin stainless are the two commercial defaults you'll most often be matching to on existing openings.
10) Which lever styles are available on the Corbin Russwin ML2000 mortise trim?
Ten lever designs: Armstrong (AS), Citation (CS), Dirke (DS), Essex (ES), Lustra cast (LS), Lustra wrought (LW), Newport (NS), Princeton (PS), and Regis (RS). Lever style is cosmetic and it is also the part that has to match the other doors on the floor, so on a repair order the lever code is the thing to get off the existing trim before ordering. Dirke is the one ordered hand-specific.
11) Is the Corbin Russwin ML2000 mortise lock Grade 1, and how many cycles is it tested to?
ANSI/BHMA A156.13 Series 1000, Operational and Security Grade 1, with a UL cycle test completed at 14.5 million cycles. Grade 1 is the top commercial durability tier and it's what most institutional and government specs call for outright, so this satisfies a Grade 1 line item on a drawing. For an MRO buyer standardizing across a campus, that cycle number is the argument for putting the same series on every high-traffic opening.
12) Should I use a mortise passage lock or a cylindrical passage set on a commercial door?
Mortise, like the ML2010, goes into a pocket machined into the edge of the door and carries a heavy steel case, a 2-3/4 inch backset, and an ANSI armored front measuring 8 x 1-1/4 inches. Cylindrical passage sets go into a simple round cross-bore and are quicker and cheaper to install. The deciding factor is the door you already have: a door prepped for a mortise pocket takes mortise hardware and nothing else, and a bored door takes cylindrical. Converting between the two means new doors or a filler kit, not just new hardware. Where you have the choice on a new opening, mortise is what carries high-traffic institutional use over decades.
13) Can I use the ML2010 trim in a high-abuse or vandal prone area like a school restroom?
The standard trim isn't the vandal-resistant version. The ML2000 Series offers a separate ML2000VR configuration with stainless steel escutcheons, tapered edges, and Torx pin tamper-resistant screws, and that is the one to specify for high-risk or high-abuse openings. Corbin Russwin also builds a Behavioral Health trim line (BHSS/BLSS) for psychiatric and detention-adjacent settings where ligature resistance is the concern. Standard sectional or escutcheon trim is thru-bolted, which helps alignment and pull-off resistance but is not a vandal-resistant rating.
14) If I later need this passage opening to lock, can I reuse the ML2010 trim?
The ML2000 Series is multi-function: 12 functions are configurable from one ML2054 lockbody, so the lock case side of a change is handled within the series. The trim, though, has to suit the new function. Passage trim has no cylinder or thumbturn cutout, so moving to a keyed or privacy function means ordering trim for that function. Note the spacing the series uses when you plan it: 3-5/8 inches (92mm) center to center from lever to cylinder, and 2-7/16 inches (62mm) lever to thumbturn.
15) Can I put Corbin Russwin ML2000 mortise locks on a coastal or hurricane zone building?
The ML2000 Series is windstorm and hurricane certified, and it also holds California State Fire Marshal listing. For a specifier working a Florida or Gulf coast opening, that means the lock is not the piece that fails the assembly review, though the door, frame, and full assembly still have to carry their own approvals.
16) Where do I find the exploded parts diagram for an older Corbin Russwin ML2000 mortise lock?
Two documents cover it. The ML2000 Series Catalog carries the current function list, trim designs, and dimensional data, and a separate ML2000 Series Mortise Lock Parts Manual covers locks manufactured prior to 2016. If you're pulling apart an existing lock in a building that's been standing a while, the pre-2016 parts manual is the one that matches what's actually in your hand.
