Corbin Russwin ML2010-LL-626 – Frequently Asked Questions

1) Does the Corbin Russwin ML2010-LL come with levers, trim, or a cylinder?
No. The ML2010-LL is the mortise lock body alone. You order the trim (knob or lever, roses or escutcheons) separately, and because it's an ANSI F01 passage function it's non-keyed, so no cylinder is needed. If you're replacing a complete lockset and the old trim is worn or the wrong design, budget for trim in the same order or you'll have a lock case with nothing to operate it.
2) Will the ML2010-LL mortise body fit my door, and what backset and door thickness does it need?
It's built for a 1-3/4 inch (44mm) door, the standard commercial thickness, on a 2-3/4 inch (70mm) backset. The steel lock case measures 5-7/8 x 4 x 15/16 inches, so the mortise pocket in the door edge has to accept that. Optional thicknesses are available from Corbin Russwin, but the catalog build is the 1-3/4 inch door. If your doors are 1-3/8 inch older interior slabs, this is not the body to specify.
3) Do I have to order the ML2010 passage mortise body handed, or can I flip it on site?
Order it and re-hand it in the field. The ML2000 Series uses a patented Quick Reversible latchbolt, so the handing is reversed without opening the lock case. That matters if you're stocking a maintenance shop or a truck: one body covers left and right hand openings instead of two part numbers.
4) What does ANSI F01 passage function actually do on a closet or corridor door?
F01 means both grips are always free and the latchbolt retracts from either side. There's no locking, no key, no thumbturn. It's the function you want on closets, storerooms with no security requirement, corridor doors, and any leaf that just needs to latch shut and pull open. If someone needs to lock that door, F01 is the wrong function and you need a keyed or privacy body from the ML2000 range instead.
5) Will the ML2010-LL latch into the strike that's already in my frame?
The latchbolt throws 3/4 inch (19mm) and it's a two-piece anti-friction design, so it takes less force to pull the door shut against a seal or closer. The standard strike is an ANSI straight lip at 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center. If your frame already has an ANSI straight lip strike prep on that spacing, it drops in. A frame cut for a non-ANSI strike, or one with a shallower pocket than a 3/4 inch throw needs, has to be re-prepped or shimmed.
6) I'm standardizing a building on Corbin Russwin ML2000 mortise locks. Does the passage body share the same door prep as the keyed functions?
It does. Every ML2000 body runs the same 2-3/4 inch backset and the same 5-7/8 x 4 x 15/16 inch case in a 1-3/4 inch door, so a passage opening and a keyed opening take the same mortise pocket and the same armored front cutout. That's how you standardize a facility: one door prep across the building, then change the function by changing the body. Center to center spacing is 3-5/8 inches (92mm) knob or lever to cylinder and 2-7/16 inches (62mm) knob or lever to thumbturn, so the trim cutouts line up across the range as well.
7) Does the ML2010 passage body work with our existing Corbin Russwin key system?
Not applicable on this one. The ML2010-LL is the F01 passage function, non-keyed, so there's no cylinder in it at all. Keyed bodies in the ML2000 Series do take new or existing Corbin Russwin key systems and accept most other manufacturers' cylinders, with a 6-pin L4 keyway 0-bitted as standard. If the opening has to key into your master system, specify a keyed ML2000 function rather than the ML2010.
8) What is the Accentra equivalent of a Corbin Russwin ML2010 mortise lock body?
The closest cross-brand match is the Accentra 8800FL Series mortise lock body with field reversible handing. Both are Grade 1 mortise lock bodies sold as the case alone, without trim, and both handle handing in the field rather than requiring a separate left-hand and right-hand part number. The Corbin Russwin ML2010 is the passage/hall/closet function, ANSI F01, so grips are always free from both sides and nothing keys. If the opening needs a keyed or locking function, the ML2010 body is not the one to match against; specify the function first, then the body. Note also that the two brands use different key systems and trim mounting, so a body swap between them is a body-plus-trim decision, not a drop-in case change.
9) Is the Accentra 8800FL lock body a drop-in replacement for a Corbin Russwin ML2010, or do I need new trim too?
Plan on new trim. Both are Grade 1 mortise lock bodies with field reversible handing, so they serve the same class of opening, but each manufacturer's lever and escutcheon trim is designed to its own case, spindle, and thru-bolt pattern. Swapping the case from one brand to the other means the existing trim will not necessarily land on the new hub or screw centers. Where the two do agree is the door itself: a mortise pocket already cut for a Grade 1 case on a 1-3/4 inch door is the same pocket either way, so the carpentry usually carries over even when the hardware does not. For a facility standardizing on one brand, staying within the ML2000 Series lets existing Corbin Russwin trim and key systems carry forward.
10) Is the ML2010 mortise lock Grade 1, and how many cycles is it tested to?
ANSI/BHMA A156.13 Series 1000, Operational and Security Grade 1. Corbin Russwin ran the ML2000 Series past the standard requirement to over 14.5 million cycles under UL cycle testing (Verification ID V875753). For a high traffic opening, a school corridor or a hospital wing, that's the number a specifier wants on the record.
11) What finishes does the ML2010-LL mortise body come in, and does the finish matter on a body that's hidden in the door?
Fourteen finishes: 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. The case itself buries in the door, but the armored front (wrought brass, bronze, or stainless, 8 x 1-1/4 inches) shows on the door edge, so match it to the trim and the hinges on the rest of the opening. 626 satin chrome is the usual commercial default.
12) Should I use a mortise lock body or a cylindrical lockset for a commercial closet door?
A mortise body like the ML2010 needs a machined pocket in the door edge, which means either a door already prepped for mortise or one you send out to be prepped. A cylindrical lock just needs a bored hole. On a new commercial or institutional opening where the rest of the doors are mortise prepped, staying mortise keeps the building consistent and gives you the heavier Grade 1 case. On a retrofit into a bored door, converting to mortise prep is real carpentry, and a cylindrical passage set is the faster path. Match what's already cut into the door.
13) Is there a field reversible Grade 1 mortise lock body from another brand I could use instead?
The Accentra 8800FL Series mortise lock body is a Grade 1 body with field reversible handing, same as the Corbin Russwin ML2010. The difference to check before you swap is the trim: mortise trim is brand specific, so an Accentra body wants Accentra trim and a Corbin Russwin body wants Corbin Russwin trim. If the building is already standardized on one brand's escutcheons and levers, stay with that brand's body.
14) Do I need to run power or wiring to the ML2010-LL?
No wiring. The ML2010-LL is a purely mechanical body with no electrical option on it, so nothing to power and nothing to fail when the building loses power. Motorized Electric Latch Retraction is a separate ML20900 series product, not something you add to this body. If the opening is on an access control system, specify from the electrified range instead.
15) I need a keyed mortise lock, not passage - is the Accentra 8800FL body the one to order instead?
Not for that reason alone. The Corbin Russwin ML2010 is the passage/hall/closet function, non-keyed, ANSI F01, and the Accentra 8800FL Series body is likewise a Grade 1 mortise case whose function is set by the model designation you order, not by the brand. Choosing between brands does not add or remove keying; the function code does. For a keyed opening, stay in the ML2000 Series and specify the keyed function that matches the door, or specify the corresponding keyed function in the Accentra series. Use the ML2010 where the door only needs latching and free operation from both sides, such as a closet, a hall door, or a corridor pair.
