Corbin Russwin COR-ML2090-NSA-626 – Frequently Asked Questions

1) Does the Corbin Russwin ML2090 mortise dummy trim have a latch, or is it push/pull only?
No latch. The ML2090 is a full active dummy: both grips stay always active and the trim works as a push or pull only, with nothing engaging a latchbolt or strike. Use it on the inactive leaf of a pair, on a closet or cased opening, or anywhere you want matching lever hardware with no latching action. If the door has to stay shut, you need a passage or storeroom function instead.
2) What door thickness does the ML2090 dummy trim fit?
1-3/4 inch (44mm) is the standard door thickness for the ML2090, which is the normal commercial door thickness. Optional thicknesses are available on the ML2000 platform if you are working with a thicker door.
3) Do I have to specify handing when I order an ML2090?
Handing is field reversible on the ML2090, so a unit can be set to the hand of your opening on site. One exception on the trim side: the Dirke (DS) lever comes as a left hand or a right hand lever, so that style has to be ordered to hand.
4) Will the ML2090 dummy trim match the other ML2000 mortise locks already on my building's doors?
That is exactly what it is for. The ML2090 uses the same ML2000 Series trim designs, levers, and finishes as the keyed and passage functions in the family, so a dummy on a closet or an inactive leaf looks identical to the working locks down the hall. Match on three things when you order: lever style (Armstrong, Citation, Dirke, Essex, Lustra, Newport, Princeton, Regis), rose or escutcheon (A rose 2-1/4 inch, F rose 2-7/8 inch, M or N escutcheon), and finish.
5) What is the closest Schlage equivalent to the Corbin Russwin ML2090 mortise dummy trim?
The Schlage L0170 is the nearest Schlage counterpart. Both are Grade 1 mortise dummy trim for 1-3/4 inch doors. The difference is coverage: the ML2090 is full active dummy trim with both grips always active, acting as a push or pull on both faces, while the L0170 is half dummy trim from the L Series. If you need a trim grip on one side only, the L0170 matches; if both faces of the door need a grip, the ML2090 is the one that covers it.
6) I need a mortise lock for a door that actually has to latch, not dummy trim. What should I order instead of the ML2090?
The ML2090 is non-latching by design, so it will not hold a door closed. For a latching passage function, the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, and the Falcon MA101 is a Grade 1 heavy duty mortise passage lock that is field reversible and fire rated. Hager also offers the 3810S passage mortise lock with rose trim and the 3810E with escutcheon, both on a 2-3/4 inch backset, which matches the ML2090 backset.
7) For a behavioral health opening, is the ML2090 the right push/pull trim or is there an anti-ligature alternative?
The ML2090 offers Behavioral Health trim designs (BHSS/BLSS) on the ML2000 platform and functions as push or pull only with no latch. If the opening needs a latching anti-ligature solution instead, the TownSteel MRX-A-01 arch trim and MRX-L-01 lever are Grade 1 heavy duty ligature resistant passage mortise locksets for 1-3/4 inch doors, and the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant.
8) Does a mortise dummy trim need a mortise pocket cut in the door?
The ML2090 is dummy trim, not a lockbody, so there is no latch case to house and no strike to prep. What it does need is the same mortise-style trim mounting pattern as the rest of the ML2000 line, with thru-bolted trim for alignment. If you are retrofitting an existing ML2000 opening, the trim footprint carries over; on a new door, prep to the ML2000 template for the rose or escutcheon you pick.
9) Is the ML2090 keyed, or can I add a cylinder later?
Non-keyed. The ML2090 has no cylinder and no keyed function at all, and there is no lockbody behind it to key. If you need key control on that opening, move to a keyed ML2000 function rather than trying to add a cylinder to dummy trim.
10) Is the ML2090 rated for a hospital or school corridor, or is dummy trim lighter duty?
It is built on the Grade 1 ML2000 platform, ANSI/BHMA A156.13 Series 1000, Operational and Security Grade 1, with heavy gauge steel construction and UL cycle testing verified at 14.5 million cycles. That puts it in the same durability class as the working locks in the series, which is why it holds up in schools, hospitals, hotels and government buildings rather than just residential closets.
11) Can the ML2090 go on a fire rated door?
The ML2000 Series is UL/cUL listed with UL10C positive pressure, rated for 3 hour fire doors up to 4 ft x 10 ft single or 8 ft x 10 ft pair. Note that on a fire rated pair, the inactive leaf still needs proper latching hardware such as flush bolts, since dummy trim provides no latching of its own.
12) What is the difference between the A rose and F rose on the ML2090?
Diameter. The A rose is 2-1/4 inches across and the F rose is 2-7/8 inches, so the F covers more of the door face, which matters if you are going over an older prep or a previous rose that left a mark. The M and N escutcheons are the tall plate options instead of a round rose. Pick the one that matches the other openings in the building.
13) Emtek also lists mortise dummy locksets. How do those differ from the Corbin Russwin ML2090?
Emtek's dummy mortise entrance locksets - the 3019 Brisbane, 3102 Memphis, 3104 Hamilton and 3106 Manhattan - are dummy function like the ML2090, but each is a fixed decorative design family. The ML2090 is a commercial Grade 1 trim on the ML2000 Series platform, configurable across nine lever designs including Armstrong, Newport and Princeton, with A and F roses or M and N escutcheons. Choose the Emtek designs for residential-style aesthetics; choose the ML2090 when the opening is specified commercial.
14) Is the Falcon MESC600DT dummy trim a substitute for the ML2090?
No. The MESC600DT is dummy escutcheon lever trim built for Falcon M9900 Series exit devices, so it mounts to an exit device rather than a mortise lock prep. The ML2090 is mortise dummy trim for a standard 1-3/4 inch mortise-prepped door. They share the dummy function but not the door prep, so they are not interchangeable.
15) We need the inactive leaf of a pair to look like the keyed leaf. What Corbin Russwin or comparable options match the ML2090 for a keyed door?
The ML2090 is non-keyed dummy trim, so it pairs with a keyed lock on the active leaf. Comparable Grade 1 keyed mortise functions include the Accentra 8805FL storeroom lock, the Cal-Royal NM8080 storeroom lockset with an interchangeable core option, and the Cal-Royal NM8050 office/entrance lockset for 1-3/4 inch doors. Matching lever style and finish across the pair is what makes the two leaves read as a set.
16) Can I use an electronic mortise lock in place of the ML2090 if I later need access control on that door?
The ML2090 is a non-electronic, non-keyed dummy trim, so it carries no credential capability at all. If the opening will need access control, Grade 1 electronic mortise options include the Schlage CO-100 standalone keypad mortise lock for 1-3/4 inch doors, the TownSteel FME-2000 RFID classroom mortise lockset, and the Dormakaba E-Plex E5086 pushbutton/card mortise lock. Those require a latching mortise prep and power or battery provisions the dummy trim does not.
17) Our spec calls for a privacy set, not dummy trim. What replaces the ML2090 on a restroom or bedroom door?
The ML2090 has no latch and no locking, so it will not satisfy a privacy spec. Grade 1 privacy mortise options include the Cal-Royal NM8440 privacy lockset with deadbolt for 1-3/4 inch doors and the Hager 3840S privacy mortise lock on a 2-3/4 inch backset, the same backset the ML2090 trim is built around.
18) Would a cylindrical passage lock work instead of the ML2090?
Only if the door prep changes. The Schlage PC10 is a Grade 1 non-keyed passage cylindrical lock with rose for 1-3/4 inch doors and needs a bored cylindrical prep. The ML2090 is mortise trim and requires a mortise pocket in the door edge. Swapping between the two means re-prepping the door, so match the hardware to the prep already cut.
19) Which finishes does the ML2090 dummy trim come in so I can match existing hardware?
Fourteen finishes across brass, bronze, nickel, chrome, stainless and coated: 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 commercial defaults. The underlying trim substrate is brass or bronze.
20) Is there a non-electrified dummy option here, or does this come with electronics?
Straight mechanical. The ML2090 has no electronics, no power, and no wiring to run. Electrified options like motorized electric latch retraction exist elsewhere in the ML2000 family, on the ML20900 series, but they do not apply to dummy trim.
