Corbin Russwin ML2010-LWM-626 – Frequently Asked Questions

1) What is a Grade 1 mortise passage lock alternative to the Corbin Russwin ML2010?
Several, depending on what else the opening needs. The Falcon MA101 is a Grade 1 heavy duty mortise passage lock, also field reversible and fire rated. The Schlage PM010 is a Grade 1 non-keyed mortise passage latch for 1-3/4 inch doors. The Hager 3810S and 3810E are Grade 1 passage mortise locks on a 2-3/4 inch backset with a wider 1-3/4 to 2-1/2 inch door thickness range, useful if your doors run thicker than standard. For behavioral health or detention openings, TownSteel's MRX-L-01 and MRX-A-01 are Grade 1 anti-ligature passage mortise locksets.
2) Does the ML2010 lock the door, or is it always free?
It never locks. The ML2010 is ANSI F01 passage function: latchbolt retracted by grip from either side, both grips always free at all times. There is no cylinder and no thumbturn, so it is for hall, closet, and corridor doors that only need to latch shut. If you need to secure the opening, order a keyed function from the ML2000 family instead, or look at a storeroom lock like the Cal-Royal NM8080 or a classroom function like the NM8070.
3) Do I have to order the ML2010 handed, or can I flip it on site?
Order it either way. The ML2010 uses Corbin Russwin's patented Quick Reversible latchbolt, so the handing is reversed in the field without opening the lock case. For a stocking contractor or a property manager keeping spares on the truck, that means one lock body covers left and right hand openings.
4) Will the ML2010 latch into the strike that is already in my frame?
The 3/4 inch (19mm) latchbolt throws into a standard ANSI strike, and the lock ships with a wrought ANSI straight lip strike measuring 4-7/8 x 1-1/4 x 1-1/8 inches lip to center. If your frame is prepped for the ANSI 4-7/8 inch strike, the supplied strike drops into the existing cutout. Frames cut for a smaller T-strike or a residential strike plate need the prep enlarged.
5) Can I use the ML2010 passage lock on a fire rated door?
Yes. The ML2000 Series is UL/cUL listed and UL10C positive pressure rated, good for 3-hour fire doors up to 4' x 10' single or 8' x 10' pair. It also meets ADA A117.1 and carries California State Fire Marshal listing. For a rated corridor or stairwell door in a school or hospital, that is the paperwork the inspector wants.
6) What is the closest equivalent to a Corbin Russwin ML2010 mortise passage lock from another manufacturer?
The Falcon MA101 is the nearest one-for-one match. It is a Grade 1 heavy-duty mortise lock carrying the same Passage/Hall/Closet function and, like the ML2010, is field reversible. The ML2010 is also Grade 1 with a Passage/Hall/Closet function and field-reversible handing, so both drop into the same non-keyed passage opening. Schlage's PM010 is a second Grade 1 non-keyed passage mortise latch, rated for 1-3/4 inch doors, which matches the ML2010 standard door thickness.
7) Is there a simpler passage lock than the Corbin Russwin ML2010 for a door that is not already mortise prepped?
Yes. The Schlage PC10 is a Grade 1 passage cylindrical lock, non-keyed with rose, for 1-3/4 inch doors. It bores into a cylindrical prep rather than a mortise pocket, so it suits a door with no mortise cutout. The ML2010 is a mortise lock type with a 2-3/4 inch backset and an ANSI straight lip strike measuring 4-7/8 inch x 1-1/4 inch x 1-1/8 inch, and needs a mortise pocket cut into the door edge.
8) The opening needs to lock, so what mortise lock should be used instead of the ML2010 passage function?
The ML2010 is non-keyed, with the latchbolt retracted by grip from either side and both grips always free, so it never secures an opening. For a keyed storeroom opening, the Accentra 8805FL is a Grade 1 storeroom mortise lock from the 8800 Series, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option. For a classroom opening, the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with auxiliary deadlatch on the same 1-3/4 inch door thickness. For an office or entrance door, the Cal-Royal NM8050 is a Grade 1 office/entrance mortise lockset.
9) What mortise lock replaces an ML2010 on a restroom or bedroom door that needs privacy?
A passage function will not hold a restroom door - the ML2010 keeps both grips always free. The Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors, matching the ML2010 standard door thickness. The Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset, the same backset the ML2010 uses, on a 1-3/4 inch to 2 inch door thickness range.
10) What passage mortise lock should be specified for a behavioral health or patient room instead of a lever ML2010?
The TownSteel MRX-L-01 is a Grade 1 heavy-duty anti-ligature lever mortise lockset in stainless steel with a Passage/Hall/Closet function, and the MRX-A-01 is the same passage function with ligature-resistant arch trim in satin stainless steel - both for 1-3/4 inch doors. For a push/pull opening, the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset, ligature resistant and ADA compliant in satin stainless steel. The ML2010 carries the same Passage/Hall/Closet function on 1-3/4 inch doors and offers Behavioral Health BHSS and BLSS trim among its trim designs.
11) Does a Baldwin 6301 or 6310 mortise lock body fit the same prep as a Corbin Russwin ML2010?
No. The Baldwin 6301 entry/apartment and 6310 entry/storeroom mortise lock bodies use a 2-1/2 inch backset, while the ML2010 uses a 2-3/4 inch backset - the cylinder and spindle holes will not line up on a door prepped for one when fitted with the other. The 6301 is offered knob by knob and as the 6301LS lever by lever for doors 1-3/4 inch and over; the 6310 covers 1-3/8 inch and over. Function differs as well: both Baldwin bodies are keyed entry functions and the ML2010 is non-keyed passage.
12) Is a mortise passage lock worth it over a cylindrical passage lock for a high traffic corridor?
It comes down to the door prep and the cycle life. The ML2010 needs a mortise pocket cut into the door edge, which is more work on a retrofit, but it is ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1 with UL cycle testing verified at 14.5 million cycles. If the door is already prepped cylindrical and you do not want to re-machine it, the Schlage PC10 is a Grade 1 cylindrical passage lock for 1-3/4 inch doors. On a new opening in a school or hospital corridor, the mortise case is the one that holds up.
13) What lever and rose options do I need to pick when ordering an ML2010?
Three choices decide the part. Lever design: Armstrong, Citation, Dirke (specified left or right hand), Essex, Lustra cast or wrought, Newport, Princeton, or Regis. Trim: A Rose at 2-1/4 inch diameter, F Rose at 2-7/8 inch diameter, or M or N escutcheon. Finish: 14 of them, from 605 bright brass and 606 satin brass through 626 satin chrome, 630 satin stainless, 613 oil-rubbed bronze, 722 black oxidized bronze, and BSP black suede powder coat. Note the Dirke lever is the one design that is ordered handed rather than reversed in the field.
14) Will the ML2010 match the finish and lever on the keyed Corbin Russwin locks already in my building?
That is the usual reason to buy it. The ML2010 is part of the ML2000 Series and shares the same lever designs, rose and escutcheon trims, and finish range as the keyed functions in the family, so a passage closet door can carry the same Newport lever in 626 satin chrome as the storeroom door beside it. For a property manager standardizing a floor, spec the same lever and finish code across both.
15) Does the ML2010 passage lock come with a cylinder or a deadbolt?
No cylinder and no deadbolt. It is a non-keyed passage function, so there is nothing to key and nothing to throw. The deadbolt and cylinder specs published for the ML2000 Series belong to the keyed and privacy functions in the family, not to the ML2010. If the closet or storeroom actually needs to be secured, move to a keyed ML2000 function or a peer like the Accentra 8805FL Grade 1 storeroom mortise lock.
16) Which passage mortise lock fits a door thicker than 1-3/4 inch?
The Hager 3810S is a passage mortise lock with a 2-3/4 inch backset covering a 1-3/4 inch to 2-1/2 inch door thickness range, and the Hager 3810E is the same passage lock with escutcheon trim over that same 1-3/4 inch to 2-1/2 inch range. The ML2010 is built for 1-3/4 inch standard with optional thicknesses available, and uses the same 2-3/4 inch backset, so the strike and edge prep line up either way. The ML2010 offers both rose and escutcheon trim - A rose at 2-1/4 inch diameter, F rose at 2-7/8 inch diameter, and M or N escutcheon.
17) Is the Schlage L0170 half dummy trim a substitute for a passage mortise lock?
No. The L0170 is a Grade 1 heavy-duty non-keyed mortise lever lock in dummy function for 1-3/4 inch doors - dummy trim does not operate a latch, so it holds nothing shut and the door needs a separate catch or stop. The ML2010 is a working mortise lock whose latchbolt retracts by grip from either side with a 3/4 inch throw anti-friction two-piece latchbolt. Use a dummy only on an inactive leaf or a false pull side.
18) Are the Emtek Brisbane and Memphis mortise entrance locksets alternatives to a Corbin Russwin ML2010?
They serve a different purpose. The Emtek 3019 Brisbane and 3102 Memphis are both dummy function mortise entrance locksets, as are the 3104 Hamilton and 3106 Manhattan - dummy trim, not an operating latch. The ML2010 is a commercial Grade 1 mortise lock with a working latchbolt retracted by grip from either side, ANSI/BHMA function F01. For a decorative opening that still has to latch, the ML2010 covers appearance through 14 finishes from bright brass through black suede powder coat and ten lever designs including Armstrong, Newport, and Princeton.
19) Which mortise lock should be used if the opening needs access control or a keypad rather than a mechanical passage function?
The ML2010 is a mechanical, non-electronic lock. For credentialed access on a mortise prep, the TownSteel FME-2000 is a Grade 1 heavy-duty classroom mortise lockset with RFID for 1-3/4 inch doors, and the Schlage CO-100 is a Grade 1 heavy-duty standalone electronic mortise lock with a keypad reader in privacy function on 1-3/4 inch doors. The Dormakaba E-Plex E5086 is a Grade 1 electronic pushbutton and card back-to-back mortise lock in entry/egress function. All three sit on the same 1-3/4 inch door the ML2010 is built for.
20) Can a BEST 45H mortise lock body replace a Corbin Russwin ML2010?
They cover different functions. The BEST 45HCAC is a heavy-duty 45H Series mortise lock body in public entrance function, field reversible, and the 45HCAINL is a heavy-duty 45HCA mortise lockbody in intruder function - public entrance and intruder both control the outside lever, while the ML2010 is ANSI F01 with both grips always free at all times. The ML2010 shares the field-reversible handing feature, re-handed without disassembling the lock case.
21) What is the difference between the Corbin Russwin ML2010 and the Hager 3850E office mortise lock?
The Hager 3850E is an office function mortise lock with lever and escutcheon, non-keyed, 2-3/4 inch backset, for doors 1-3/4 inch to 2-1/2 inch. The ML2010 is also non-keyed on a 2-3/4 inch backset, but its function is passage - the latchbolt retracts by grip from either side with both grips always free, so there is no way to hold the outside lever locked. Choose the office function when the room has to be secured from inside without a key.
22) Which mortise lock suits a dormitory corridor door where an ML2010 passage function is not enough?
The Sargent 7925 is a Grade 1 heavy-duty dormitory exit function mortise lock with rose trim and a single cylinder deadbolt, from the 7900 Series, in corridor/dormitory function. That gives a keyed corridor side and a deadbolt the occupant can throw, where the ML2010 is non-keyed with both grips always free. Both are Grade 1 mortise locks, so the door edge prep and strike work stays the same class of job.
23) Will a Codelocks CL2255 or a Marks USA 21AC work in place of a Grade 1 commercial passage mortise lock?
Neither matches the duty of the ML2010. The Codelocks CL2255 is a medium duty electronic tubular mortise latch in brushed steel, and the Marks USA 21AC is an ornamental iron mortise lock in entrance double cylinder function built for 1 inch doors, as is the 22AC. The ML2010 is a Grade 1 commercial mortise lock for 1-3/4 inch doors with a heavy-gauge steel lockcase, cycle tested to 14.5 million cycles. For high-traffic commercial and institutional openings, hold to the Grade 1 heavy-duty class.
24) Is the ML2010 an electronic or access-control lock?
It is purely mechanical, no wiring, no power, no credential reader. For an opening that needs card or keypad access on a mortise prep, the electronic options are a different class of product: the Schlage LEMD-GRW ENGAGE wireless mortise lock with a 125kHz proximity reader, the TownSteel FME-2000 RFID Grade 1 mortise lockset, or the Dormakaba E-Plex 2066 pushbutton keyless mortise lock.
25) What is the ML2010 lock trim made of, and which finishes hold up in a wet or coastal building?
Trim substrate is brass or bronze. For openings that see moisture or salt air, the stainless steel finishes are the ones to spec: 629 bright stainless steel or 630 satin stainless steel. 626 satin chrome is the workhorse for interior commercial corridors. The ML2000 Series also carries a windstorm and hurricane certification.
26) Is a Sargent 4874 mortise deadbolt an alternative to the ML2010?
No - it is a companion, not a replacement. The Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset with no latch and no lever, so it secures a door but does nothing to keep it closed in use. The Kaba Ilco 185 Series is likewise a deadbolt function mortise lock. The ML2010 is a latching passage lock with a 3/4 inch throw two-piece anti-friction latchbolt and grips on both sides. A deadbolt of this kind can be added above a passage lock where the opening needs to be secured after hours.

    Smooth Functionality, Limited Aesthetic Options

    Posted by Peter on Dec 26th 2023

    This Corbin Russwin ML2010 mortise lock is smooth as butter in function - reliable and sturdy. But, if you're into aesthetics, the design options are pretty limited, so it might not match every style preference out there.
