Corbin Russwin COR-ML2070-NSA-626 – Frequently Asked Questions

1) What does the Corbin Russwin ML2070 actually do - is there a working latch behind it?
No latch, no lockbody. The ML2070 is full dummy mortise trim: the levers act as pulls only, with no operation at all. Use it on the inactive leaf of a pair, on a closet or a false door where you want the opening to match the working mortise locks around it. If you need a lever that retracts a latch but never locks, order a passage function instead.
2) Will Corbin Russwin ML2070 dummy trim fit a 1-3/4 inch door?
1-3/4 inches (44mm) is the standard door thickness for the ML2070, and optional thicknesses are available on the ML2000 platform. On a standard commercial 1-3/4 inch leaf it is a straight fit.
3) Do I have to specify handing when I order ML2070 dummy trim?
Handing is field reversible on the ML2070, so a lever ordered for one hand can be turned around on site. One exception on the lever axis: the Dirke design is ordered as a specific hand, DS Left Hand or DS Right Hand, so that one you pick up front. Everything else in the lever range is symmetric to order.
4) What do I need to specify to order Corbin Russwin ML2070 trim correctly?
Three choices. Lever design: Armstrong, Citation, Dirke, Essex, Lustra, Newport, Princeton or Regis. Rose or escutcheon: A rose at 2-1/4 inch diameter, F rose at 2-7/8 inch diameter, M escutcheon or N escutcheon. Then finish, from 605 bright brass through 630 satin stainless to BSP black suede powder coat. Match the rose or escutcheon to whatever is on the working locks nearby, or the dummy will read as an odd door out.
5) Will the ML2070 dummy match the other Corbin Russwin ML2000 locks already on my building's doors?
Yes, and that is the point of it. The ML2070 is ML2000 Series trim, so it shares the same lever designs and rose or escutcheon shapes as the keyed and non-keyed ML2000 functions already hung in the building. Order the same lever design, the same rose or escutcheon, and the same finish code as the working locks and the dummy leaf is indistinguishable from them. Fourteen finishes are offered, so matching an existing 626 satin chrome or 630 satin stainless fleet is straightforward.
6) Is the Corbin Russwin ML2070 Grade 1, and is it rated for a fire door?
Grade 1 by ANSI/BHMA A156.13 Series 1000, operational and security. The ML2000 platform is UL and cUL listed to UL10C positive pressure, good for a 3 hour fire door up to 4 by 10 feet single or 8 by 10 feet pair, and it also carries ADA A117.1, California State Fire Marshal and windstorm/hurricane certification. For a spec-driven institutional job that is the paperwork a submittal wants.
7) If the door actually needs to latch instead of just pull, what should be used instead of an ML2070?
The ML2070 has no operation at all - the grips act as pulls only. For an opening that needs a latch but no key, 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 from the MA Series with field reversible operation and a fire rating. Both retract a latch from the lever; the ML2070 does not.
8) For a behavioral health or anti-ligature opening, is the ML2070 the right trim?
For ligature-resistant openings, the TownSteel MRX-L-01 is a Grade 1 heavy duty stainless steel anti-ligature lever mortise lockset in passage function for 1-3/4 inch doors, the MRX-A-01 is the same passage function with satin stainless arch trim, and the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant. The Corbin Russwin ML2070 is dummy lever trim with no operation, and the ML2000 platform offers Behavioral Health BHSS and BLSS trim designs if a fixed pull is what the opening calls for.
9) Does a mortise dummy like the ML2070 need a mortise pocket cut in the door?
The ML2070 is mortise trim without a lockbody, so there is no latch case to house and no 2-3/4 inch backset mortise prep required for the trim itself to function. It is the ML2000 mortise lever and rose set on its own. On a door already mortise prepped, it covers and matches; on a new blank door you are mounting trim only. If you need a full working mortise lock in the same family, the ML2000 lockbody functions are the ones with the case, latchbolt and deadbolt.
10) Is the ML2070 keyed, or does it take a cylinder?
Non-keyed. The ML2070 takes no cylinder and has no keyway, because there is nothing to lock. If you need the same lever and rose look with a key, choose a keyed ML2000 function; those use a 6-pin L4 keyway cylinder, work with new or existing Corbin Russwin key systems, and accept most other manufacturers' cylinders.
11) Is a mortise dummy overkill for a closet door, or should I use a cheaper passage lever?
If the door never latches, dummy trim is the right call and the ML2070 is the heavy commercial version of it, built on the ML2000 platform tested to 14.5 million cycles. If the door needs to stay closed and the lever needs to retract a latch, buy a passage function instead: the Schlage PM010 Grade 1 mortise passage or the Hager 3810S 3800 Series Grade 1 passage with a 2-3/4 inch backset both do that in mortise, and the Schlage PC10 does it cylindrical if the door has a bore rather than a pocket.
12) What is the difference between the Corbin Russwin ML2070 and the Schlage L0170 dummy trim?
Both are Grade 1 mortise dummy lever trim for a 1-3/4 inch door, so functionally they land in the same place. The split is family and coverage: the L0170 is Schlage L Series and half dummy, while the ML2070 is full dummy on the Corbin Russwin ML2000 platform with levers on both faces. Pick by what is already hanging in the building, because dummy trim earns its keep by matching the working locks around it.
13) I need dummy trim on an exit device leaf, not a mortise door - is the ML2070 right?
No. The ML2070 is mortise trim and mounts to the door face on a mortise pattern. If the leaf carries an exit device, you want dummy trim built for that device: the Falcon MESC600DT dummy escutcheon lever trim is made for M9900 Series exit devices and is fire rated. Wrong-family dummy trim will not line up with the device's mounting.
14) Which rose size should I pick on the ML2070, and does it matter for covering an old prep?
Two rose diameters are offered: the A rose at 2-1/4 inches and the F rose at 2-7/8 inches. On a retrofit where the previous trim left marks or an oversized hole in the face, the 2-7/8 inch F rose covers more than the 2-1/4 inch A. If you need to cover a tall scar down the stile, go to the M or N escutcheon instead of a rose.
15) Is a passage lock a substitute for a mortise dummy trim on an inactive leaf?
They are different parts. The Hager 3810S is a Grade 1 passage mortise lock with rose and a 2-3/4 inch backset, and the Hager 3810E is the same passage function with an escutcheon; both fit 1-3/4 inch to 2-1/2 inch doors and require a mortise pocket for a working lock case. The Corbin Russwin ML2070 is dummy trim, non-keyed, with no operation - the grip is fixed and serves as a pull. On an inactive leaf where nothing latches, the passage locks add a latch and strike prep you do not need.
16) The opening needs to lock but the trim style should match the rest of the doors - what pairs with a dummy lever?
For keyed openings alongside dummy trim, the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option. For office function, the Cal-Royal NM8050 is Grade 1 for 1-3/4 inch doors. The Corbin Russwin ML2070 covers only the fixed-pull openings in that same run and is non-keyed.
17) Can a cylindrical passage lock replace mortise dummy trim?
No - the prep is different. The Schlage PC10 is a Grade 1 non-keyed passage cylindrical lock with rose for 1-3/4 inch doors, and a cylindrical lock installs in a bored hole. The Corbin Russwin ML2070 is mortise trim for 1-3/4 inch doors and mounts to a mortise-prepped door. If the door is bored rather than mortised, the mortise trim will not fit the existing prep.
18) The door is thinner than 1-3/4 inches - what mortise options fit?
The Corbin Russwin ML2070 is built for 1-3/4 inch doors as standard. If the leaf is thinner, the Baldwin 6310 entry/storeroom mortise lock body covers 1-3/8 inch and over, and the 6310190RRLS is the lever-by-lever version of that same range. Both are keyed entry/storeroom function rather than dummy, so match the function to the opening before ordering.
19) Is there a residential-looking mortise dummy if the ML2070 is too commercial for the job?
The ML2070 is built for commercial, institutional and government openings, with a lever range that reads as contract hardware. On a decorative residential or boutique hospitality door, Emtek's mortise dummy sets are the ornamental route: the 3019 Brisbane, 3102 Memphis, 3104 Hamilton and 3106 Manhattan are all dummy function mortise entrance sets. Spec the Emteks for appearance, the ML2070 where the rest of the floor is ML2000.
20) Does the Corbin Russwin ML2070 need power or wiring?
No. The ML2070 is purely mechanical dummy trim, non-electronic, with nothing to energize. If the opening needs electric control on the same ML2000 look, the electrified options live on the working functions, including motorized electric latch retraction on the ML20900 series.
21) Does an electronic mortise lock do what the ML2070 does?
No. Electronic mortise locks such as the TownSteel FME-2000, a Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors, or the Schlage CO-100 standalone electronic mortise lock in privacy function, control access and need power and credentials. The Corbin Russwin ML2070 is non-electronic and non-keyed - the grips act as pulls only. They serve different openings in the same door schedule.
22) Is a mortise thumbturn or deadbolt an alternative to dummy trim?
They are separate parts, not substitutes. The Sargent 130KB is a standard duty mortise thumbturn from the 8200 Series and the 130W is a mortise thumbturn with a round backplate from the 7800 Series; the Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset. None of those give you a lever. The Corbin Russwin ML2070 supplies the lever trim itself, in A and F roses and M and N escutcheons.
