Corbin Russwin COR-ML2050-NSA-626 – Frequently Asked Questions

1) What does the Corbin Russwin ML2050 actually do on a door, and does it lock?
Nothing moves and nothing locks. The ML2050 is half dummy mortise trim from the ML2000 Series: the grip acts as a pull only, with no operation. It is non-keyed, so there is no cylinder and no latch. Use it on the inactive leaf of a pair, on a closet or louvered door, or anywhere you want the lever to match the working openings without any hardware function behind it.
2) Half dummy or full dummy - which one is the ML2050?
Half. The ML2050 is half dummy trim, meaning a lever on one face only. If you need a pull on both faces of the leaf, half dummy trim gets you one side and you would need a second piece for the other. On a pair of doors where only the corridor side is seen, half dummy is the usual call.
3) Do I have to specify handing for the ML2050 dummy trim?
Handing is field reversible on the ML2050, so a left hand opening and a right hand opening take the same part in most cases. The one exception is the lever style: the Dirke (DS) lever is offered as a distinct left hand and right hand version, so if you are specifying Dirke you do need to call the hand. Armstrong, Citation, Essex, Lustra, Newport, Princeton and Regis are not split that way.
4) What do I need to specify to order Corbin Russwin ML2050 dummy trim?
Three choices settle the order. Lever style: Armstrong (AS), Citation (CS), Dirke (DS, called left or right hand), Essex (ES), Lustra (LS), Newport (NS), Princeton (PS) or Regis (RS). Rose or escutcheon: A rose at 2-1/4 inch diameter, F rose at 2-7/8 inch diameter, M escutcheon or N escutcheon. Finish: fourteen of them, from 605 bright brass through 630 satin stainless to BSP black suede powder coat. Match all three to whatever the working locks on the same run already carry, or the dummy leaf will read as an odd one out.
5) I need the dummy leaf to match the working ML2000 locks already on my building. Will this do it?
That is exactly what the ML2050 is for. It takes the same lever designs, the same rose and escutcheon options and the same finish range as the functioning ML2000 Series locks, so the dead leaf carries an identical lever and trim to the one beside it. Order the same lever letter, the same rose or escutcheon type and the same finish number as the active lock and the two read as one set.
6) I need a lever that turns but does not lock. Is the ML2050 the right part?
No. Dummy trim does not turn and has no latch, so it will not hold a door closed. What you want is a passage function lock. Grade 1 mortise passage options include the Falcon MA101, which is heavy duty and field reversible, and the Schlage PM010 passage latch mortise lock for 1-3/4 inch doors. If the opening is cylindrical prep rather than mortise, the Schlage PC10 Grade 1 passage lock is the cylindrical version.
7) What is the closest equivalent to a Corbin Russwin ML2050 half dummy trim from another manufacturer?
The Schlage L0170 is the direct counterpart. It is a Grade 1 mortise non-keyed half dummy lever trim in the Schlage L Series, rated heavy duty, for a 1-3/4 inch door. The Corbin Russwin ML2050 is likewise a Grade 1 mortise dummy trim for 1-3/4 inch doors, non-keyed, with grips acting as pulls only and no operation. The practical difference is the series ecosystem: the ML2050 matches the rest of the ML2000 Series trim on adjacent doors, while the L0170 matches Schlage L Series trim. If the other doors in the opening are already ML2000, the ML2050 keeps lever style and rose or escutcheon consistent across them.
8) The door needs to latch when it closes, not just have a pull on it. What should be ordered instead of the ML2050?
A dummy trim is the wrong part for that opening. The Corbin Russwin ML2050 has grips that act as pulls only with no operation, so nothing retracts a latch. For a door that latches but never locks, a passage mortise lock is the part: 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 a fire rating, and the Hager 3810S is a 3800 Series Grade 1 passage mortise lock with rose and a 2-3/4 inch backset for 1-3/4 inch to 2-1/2 inch doors. The ML2050 remains correct for the inactive leaf of a pair, where the pull only needs to match the active leaf.
9) Will a Corbin Russwin ML2050 fit a door prepped for a 2-1/2 inch backset mortise lock?
No. The ML2050 is an ML2000 Series mortise trim built around the series 2-3/4 inch backset case, matching peers such as the Hager 3810E 3800 Series Grade 1 passage mortise lock with escutcheon and 2-3/4 inch backset. Doors prepped for a 2-1/2 inch backset take a different family: the Baldwin 6301 entry/apartment mortise lock body is a 2-1/2 inch backset unit offered knob by knob or lever by lever for 1-3/4 inch and over doors, and the Baldwin 6310 entry/storeroom body is 2-1/2 inch backset for 1-3/8 inch and over. Confirm the existing mortise pocket and cross bore centers before ordering trim.
10) A rose or an escutcheon on the ML2050 - which should I pick?
It comes down to what is on the door now and what you are covering. The A rose is 2-1/4 inches in diameter and the F rose 2-7/8 inches, both small round trims. The M and N escutcheons are full plates. If the leaf was previously prepped for escutcheon trim, a rose will not cover the old prep, so go escutcheon. On new prep or a clean door face, either works and the choice is aesthetic, matching whatever the active locks carry.
11) Does the ML2050 need a mortise pocket cut in the door?
It is mortise trim, so it mounts to a door prepped for mortise hardware rather than a bored cylindrical hole. On a genuine dummy application there is no lock case doing work behind it, but the prep and the trim footprint follow the ML2000 mortise pattern, which is why it drops onto a leaf already cut for an ML2000 lock. A door bored for a cylindrical lockset is the wrong prep for this part.
12) Can the ML2050 be keyed into our master key system?
No, and it does not need to be. The ML2050 is non-keyed with no cylinder, because there is nothing to lock. If the opening needs to key into an existing Corbin Russwin system, you are looking at a functioning ML2000 lock instead, not this trim.
13) For a door thicker or thinner than 1-3/4 inch, is the ML2050 still the right dummy trim?
The ML2050 is specified at 1-3/4 inch door thickness as standard. Peers in the set span other ranges: the Hager 3840S 3800 Series Grade 1 privacy mortise lock covers 1-3/4 inch to 2 inch, the Hager 3850E Grade 1 office mortise lock with lever and escutcheon covers 1-3/4 inch to 2-1/2 inch, the Alarm Lock DL2700CR Trilogy T2 electronic mortise lock covers 1-5/8 inch to 1-7/8 inch, and the Marks USA 21AC ornamental iron mortise lock is built for 1 inch doors. Measure the leaf at the lock edge, since dummy trim has to sit flush on the face the same way an active lockset does.
14) Is there a simpler way to put a matching pull on a door than a mortise dummy trim?
Yes, depending on what the door already has. The Corbin Russwin ML2050 is a mortise dummy trim, so it is sized and prepped to sit on a mortise-prepped door alongside other ML2000 Series trim. If the door carries an exit device rather than a mortise lock, the Falcon MESC600DT is a dummy escutcheon lever trim built for M9900 Series exit devices and is fire rated. For a decorative wood or residential-style door, Emtek offers mortise dummy locksets in several designs, including the 3102 Memphis, 3104 Hamilton, 3106 Manhattan, and 3019 Brisbane in brass. The ML2050 is the one to specify when the goal is design continuity with Grade 1 ML2000 hardware in a commercial facility.
15) Can a Corbin Russwin ML2050 replace a storeroom or classroom mortise lock on a door that is being converted to a pull?
It can, with the understanding that all lock function goes away. The ML2050 is a non-keyed dummy trim whose grips act as pulls only with no operation. A storeroom lock such as the Accentra 8805FL, a Grade 1 storeroom mortise lock in the 8800 Series, or the Cal-Royal NM8080, a Grade 1 storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors, keeps the door secured and keyed. A classroom lock such as the Cal-Royal NM8070, Grade 1 for 1-3/4 inch doors, retains keyed classroom control. Swapping to the ML2050 on a formerly keyed opening means the door no longer latches or secures, so it suits an opening that is being permanently fixed or made inactive rather than one still in service as a secured room.
16) Which mortise parts look like a dummy trim substitute but are not?
Three come up often. A mortise thumbturn such as the Sargent 130KB, a standard duty 8200 Series thumbturn, or the Sargent 130W with a round backplate in the 7800 Series, mounts on a mortise case but operates a deadbolt rather than serving as a pull. A mortise deadbolt such as the Sargent 4874 double cylinder unit with a 2-3/4 inch backset, or the Kaba Ilco 185 Series deadbolt with no handing, secures the door and provides no grip at all. And a cylindrical passage lock such as the Schlage PC10, Grade 1 non-keyed with rose for a 1-3/4 inch door, needs a cylindrical bore rather than a mortise pocket. The Corbin Russwin ML2050 is the mortise dummy trim itself, non-keyed, field reversible, with grips acting as pulls only.
17) The trim has to be ligature resistant for a behavioral health unit. Does the ML2050 work, or is there an alternative?
For a ligature resistant opening, look at purpose built anti-ligature trim. The TownSteel MRX-A-01 is a satin stainless steel ligature resistant arch trim mortise lockset, Grade 1 heavy duty, passage function, for 1-3/4 inch doors, and the MRX-L-01 is the Grade 1 heavy duty anti-ligature lever version in stainless steel for the same door thickness. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset, ligature resistant and ADA compliant, in satin stainless steel. The Corbin Russwin ML2050 is a Grade 1 mortise dummy trim in brass or bronze substrate with lever and rose or escutcheon trim, so it is the choice where the requirement is matching ML2000 Series appearance on an inactive leaf rather than ligature resistance.
18) The opening needs credential access or a keypad. What takes the place of the ML2050 there?
The ML2050 is a mechanical, non-electronic dummy trim, so an access controlled opening needs a different lock entirely. Electronic mortise options include the Schlage CO-100 standalone electronic mortise lock, Grade 1 heavy duty with a keypad reader and privacy function for 1-3/4 inch doors; the Schlage LEMD-GRW, a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating; the TownSteel FME-2000, a Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors; and the Alarm Lock DL3500CR, a Grade 1 Trilogy electronic mortise lock with 300 user codes and classroom function for 1-5/8 inch to 1-7/8 inch doors. The ML2050 stays the right part on the leaf of that same pair or the adjacent inactive door, where a pull is all that is wanted.
19) What finishes does the Corbin Russwin ML2050 come in?
Fourteen, covering the full commercial range: 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 most commercial work 626 satin chrome and 630 satin stainless are the two that match an existing building standard.
20) Do any mortise dummy trims come in a stainless steel finish rather than brass or bronze?
The ML2050 uses a brass or bronze substrate and is offered in finishes that include 629 Bright Stainless Steel and 630 Satin Stainless Steel, along with satin chrome, satin nickel and black suede powder coat, across lever styles such as Armstrong, Lustra, Newport and Regis. Among comparable dummy and passage trim, the Falcon MESC600DT is a fire rated dummy escutcheon lever trim for M9900 Series exit devices, and the TownSteel MRX-A-01 and MRX-L-01 are stainless steel Grade 1 heavy duty mortise locksets. For an opening where the existing ML2000 hardware is a particular finish code, matching the ML2050 to that same code keeps the run consistent.
