Corbin Russwin ML2080 Mortise Half Active Dummy Trim Non-Latching Push/Pull, Grade 1, Field Reversible

Commercial-Grade Mortise Dummy Trim for High-Traffic Applications

The Corbin Russwin ML2080 is a half active dummy mortise trim from the ML2000 Series, engineered for commercial, institutional, industrial, and government environments where non-latching operation is required. The grip is always active, functioning as a push or pull only — with no latching or locking mechanism engaged. Designed for a standard door thickness of 1-3/4" (44mm) and featuring field-reversible handing, the ML2080 integrates seamlessly into the ML2000 Series platform, which is constructed of heavy-gauge steel and backed by a 10-year warranty. The ML2000 Series has been UL cycle tested above and beyond standard requirements, completing 14.5 million cycles (Verification ID: V875753), making it one of the most rigorously validated mortise lock platforms available for demanding commercial use.

Corbin Russwin COR-ML2080-NSA-626 – Frequently Asked Questions

1) What does the Corbin Russwin ML2080 actually do, does it latch at all?
No latching, and no locking. The ML2080 is a half active dummy mortise trim: the grip is always active and works as a push or pull only. Use it on the inactive leaf of a pair, on a closet or panel door, or anywhere you want matching ML2000 Series lever trim with no latch or bolt operating.
2) Do I need to order the ML2080 handed, or can I flip it in the field?
Handing is field reversible on the ML2080, so one unit covers left or right hand openings. One exception on the trim side: the Dirke (DS) lever is listed as a left hand or a right hand part, so that lever style has to be specified for the hand of the door.
3) Can I get the ML2080 dummy to match the levers and roses on the working locks in my building?
That is the point of it. The dummy is offered in nine ML2000 lever styles (Armstrong, Citation, Dirke, Essex, Lustra, Newport, Princeton, Regis) and four trim plates: A rose at 2-1/4 inch diameter, F rose at 2-7/8 inch diameter, M escutcheon and N escutcheon. Pick the same lever, trim and finish as the active openings and the inactive leaf reads identical.
4) What is the mortise prep for the ML2080, and is it the same 2-3/4 inch backset as the rest of the series?
The ML2000 platform works to a 2-3/4 inch (70mm) backset, which is the standard commercial mortise backset, with a lockcase of 5-7/8 x 4 x 15/16 inches and an 8 x 1-1/4 inch armored front. Because the ML2080 is a dummy, there is nothing latching into the frame, so no strike prep is needed on the jamb.
5) What is the equivalent half dummy mortise trim from another brand?
Schlage's L Series L0170 half dummy trim is the direct cross: Grade 1, heavy duty, dummy function, 1-3/4 inch door. Choose on what is already hanging in the building, since the value of a dummy is matching the lever and rose on the adjacent active locks. Emtek also offers mortise dummy locksets (3019 Brisbane, 3102 Memphis, 3104 Hamilton, 3106 Manhattan), but those are decorative residential-style trims rather than a commercial Grade 1 match.
6) The door needs a latch so it stays closed - what should I use instead of an ML2080?
The ML2080 is non-latching; the grip is always active and acts as a push or pull only, so it will not hold a door closed. For a latching but non-locking opening, the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, the Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation, and the Hager 3810S and 3810E are Grade 1 passage mortise locks with a 2-3/4 inch backset, offered with rose and escutcheon trim respectively.
7) I need a dummy lever trim for an exit device, not a mortise lock - what is the right part?
The ML2080 is mortise dummy trim for a mortise prep. If the door carries a Falcon M9900 Series exit device, the Falcon MESC600DT is a dummy escutcheon lever trim made for that device and is fire rated. Choose the MESC600DT for exit device applications and the ML2080 for a mortise-prepped door.
8) Does the ML2080 dummy take a cylinder or a key?
Non-keyed. There is no cylinder and no keying on the ML2080 dummy trim, and it is a purely mechanical part with no electrical option. If you need a keyed mortise function in the same ML2000 Series trim, you want a keyed ML2000 lock body rather than the 2080.
9) Is a dummy trim really Grade 1, and does that matter if it does not latch?
The ML2080 carries ANSI/BHMA A156.13 Series 1000 Grade 1, operational and security, as part of the ML2000 Series platform. On a dummy the value is in the trim itself: cast lever, thru-bolted mounting, and the same heavy construction as the active locks around it, which is what holds up when people pull on an inactive leaf all day.
10) Can the ML2080 go on a fire rated opening?
The ML2000 Series is UL/cUL listed to UL10C positive pressure, rated for 3-hour fire doors up to 4 by 10 feet single or 8 by 10 feet pair, and the platform is listed for ADA A117.1 and California State Fire Marshal. On a pair, the dummy goes on the inactive leaf, so the latching and fire hardware duty falls to the active leaf device.
11) What is the ML2080 made of, and will it hold up in a school or hospital corridor?
Trim substrate is brass or bronze over the ML2000 heavy-gauge steel platform, thru-bolted for alignment. That platform has been UL cycle tested to 14.5 million cycles (Verification ID V875753), well past standard commercial requirements, which is why it gets specified in schools, hospitals, hotels and government buildings. For abuse-prone openings the ML2000VR option adds vandal-resistant stainless escutcheons with tapered edges and Torx pin tamper-resistant screws.
12) For a behavioral health or anti-ligature opening, is the ML2080 the right trim?
A standard ML2080 lever dummy is not an anti-ligature trim, though the ML2000 Series does offer Behavioral Health trim (BHSS/BLSS) if you need to stay on the Corbin platform. For a push/pull or ligature resistant mortise set, look at the Marks USA 5PDN Grade 1 hospital passage push/pull paddleset (ligature resistant, ADA, satin stainless) or TownSteel's Grade 1 anti-ligature mortise passage sets, the MRX-A-01 arch trim and MRX-L-01 lever, both for 1-3/4 inch doors.
13) The opening needs keyed control - what takes the place of an ML2080?
The ML2080 is non-keyed with no locking mechanism. For keyed control on a mortise prep, the Accentra 8805FL is a Grade 1 storeroom mortise lock with an Arcadia lever, the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option, and the Cal-Royal NM8050 is a Grade 1 office/entrance mortise lockset with auxiliary deadlatch.
14) Can I use the Schlage PC10 in place of the ML2080?
Only if the door is prepped for a cylindrical lock. The Schlage PC10 is a Grade 1 non-keyed passage cylindrical lock with rose for 1-3/4 inch doors, so it needs a bored cylindrical prep and it latches. The ML2080 is mortise trim for a mortise pocket and does not latch.
15) We want keypad or credential access on this door - what mortise options replace an ML2080?
The ML2080 is non-electronic. For electronic mortise options, the Accentra nexTouch NTM623-NR offers a capacitive touchscreen keypad with cylinder override, Schlage CO-100-MS-40-KP is a Grade 1 standalone electronic mortise lock with keypad reader in privacy function for 1-3/4 inch doors, and TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors.
16) For a bathroom that needs privacy, what mortise lock should I order instead of the ML2080?
The ML2080 has no locking mechanism, so it cannot provide privacy. The Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors, and the Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset for 1-3/4 to 2 inch doors.
17) What finishes does the Corbin Russwin ML2080 come in?
Fourteen: 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. 626 and 630 are the usual specs on commercial and institutional work.
18) Will a Sargent 130KB thumbturn work as a substitute for ML2080 dummy trim?
No. The Sargent 130KB is a standard duty mortise thumbturn for the 8200 Series, and the 130W is a mortise thumbturn with a round backplate for the 7800 Series - both are thumbturn pieces, not a lever grip. The ML2080 is half active dummy lever trim whose grip acts as a push or pull.
