Corbin Russwin COR-ML2032-NSA-626 – Frequently Asked Questions

1) Is the Corbin Russwin ML2032 safe to use on a door that people need to exit through?
No, and this is the decision point on the ML2032. It's an ANSI F30 institution/utility function: the latchbolt is retracted by key from either side and both grips stay rigid at all times, so nobody gets out without a key. That's not free egress, and on an egress path it's a life safety hazard. Use it only where an approved code path allows a double-cylinder lock, storage rooms, utility closets, secure institutional spaces with staff key control. If the opening is on a means of egress, a storeroom function like the Cal-Royal NM8080 or a classroom function like the NM8070 keeps the inside lever free.
2) Will the ML2032 mortise lock fit a 1-3/4 inch door with a 2-3/4 inch backset prep?
That's exactly the prep it's built for. The ML2032 is a 2-3/4 inch backset mortise lock for 1-3/4 inch (44mm) doors, which is the standard commercial thickness. The lockcase measures 5-7/8 x 4 x 15/16 inches and the armored front is 8 x 1-1/4 inches, so it drops into a standard ANSI mortise pocket. Optional thicknesses are available if the door is heavier than 1-3/4 inches.
3) Do I have to order the ML2032 handed, or can I re-hand it in the field?
Order it and hand it on site. The ML2032 uses Corbin Russwin's patented Quick Reversible latchbolt, so handing is reversed without opening the lock case, no disassembly and no second part. One caveat on trim: the Dirke lever is offered as a left hand and a right hand version, so if that's the lever you want, the hand has to be specified with the order. The other lever designs are not split by hand.
4) Will the ML2032 latch into the strike that is already in my frame?
Depends what's in the frame now. The ML2032 throws a 3/4 inch (19mm) two-piece anti-friction latchbolt plus a 9/16 inch effective-throw deadlocking auxiliary latch, and the deadbolt is a one-piece stainless steel bolt with a 1 inch throw. It ships with an ANSI straight lip strike, 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center. If your frame already carries a standard 4-7/8 inch ANSI mortise strike box, the latch and lip geometry line up. If the existing strike is a T-strike or a non-ANSI box, plan on swapping to the supplied strike, and remember the deadbolt needs its own pocket depth for the full 1 inch throw.
5) Can I put the ML2032 on my existing Corbin Russwin master key system, or use my own cylinders?
Both work. Standard build is a brass 6-pin conventional cylinder in the L4 keyway, shipped 0-bitted so a locksmith can key it to an existing or new Corbin Russwin system. The lock also accepts most other manufacturers' cylinders. If you're running interchangeable core, order it CL6 for LFIC 6-pin less core or CL7 for LFIC 7-pin less core and drop your own cores in. LC (less cylinder) is there if you're supplying everything yourself. Keying is specified at order as KD keyed different or KA keyed alike when a run of doors needs to share one key.
6) Is the ML2032 approved for a 3 hour fire rated opening?
Yes. The ML2032 is UL/cUL listed and UL10C positive pressure rated, good for a 3-hour fire door up to 4 ft x 10 ft single or 8 ft x 10 ft pair. It also carries ANSI/BHMA A156.13 Series 1000 Grade 1 for both operational and security, ADA A117.1, California State Fire Marshal, and windstorm/hurricane certification. Worth noting for the fire-door file: the F30 double-cylinder function itself has to be permitted by code on that opening.
7) For a behavioral health room, is the ML2032 the right mortise lock or should I use an anti-ligature set?
The ML2032 is a Grade 1 institution and utility function lock and is offered with Behavioral Health trim within the ML2000 range. Where the specification calls for a dedicated ligature-resistant assembly rather than a keyed institution function, the TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in stainless steel with a passage function on a 1-3/4 inch door, and the MRX-A-01 is the same passage function with ligature resistant arch trim. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset, ligature resistant and ADA compliant in satin stainless. Those three are passage - they do not lock - so they suit patient-side openings where the ML2032 suits an opening that must stay key-controlled.
8) What is the closest Grade 1 mortise substitute for a Corbin Russwin ML2032 on a 1-3/4 inch door?
The ML2032 is a Grade 1 mortise lock built for 1-3/4 inch doors with a double cylinder keyed function - latchbolt by key from either side, both grips always rigid. Among Grade 1 mortise peers on the same 1-3/4 inch door thickness, the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset and the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series. Both are storeroom function, which is keyed on one side with the inside lever always free, so they will not reproduce the key-both-sides operation of the ML2032. If the specification calls for key control from each side, stay with the ML2032; if the intent is a keyed outside lever with free egress inside, the NM8080 or 8805FL is the closer match.
9) The ML2032 does not allow free egress - what mortise lock should I use on an exit door instead?
The ML2032 is an asylum, institution and utility function where both grips are always rigid and the latchbolt retracts only by key, so it is not suitable where a code-required exit path must open from the inside without a key. For a corridor or dormitory opening that needs egress, the Sargent 7925 is a Grade 1 heavy duty mortise lock with a corridor/dormitory exit function and single cylinder deadbolt. For a classroom opening, the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset on a 1-3/4 inch door. For an office or entrance opening, the Cal-Royal NM8050 is a Grade 1 office/entrance mortise lockset with auxiliary deadlatch on the same door thickness.
10) Can a Baldwin 6301 or 6310 mortise lock body drop into the same door prep as an ML2032?
No. The ML2032 uses a 2-3/4 inch backset, while the Baldwin 6301 entry/apartment and 6310 entry/storeroom mortise lock bodies are 2-1/2 inch backset units. The 2-1/2 inch backset places the spindle and cylinder at a different distance from the door edge, so the cross bore and trim holes will not line up with an ML2032 prep. The Baldwin 6301 is listed for 1-3/4 inch and over door thickness and the 6310 for 1-3/8 inch and over; the ML2032 is a 1-3/4 inch standard with optional thicknesses. Treat the Baldwin bodies as a separate prep, not a retrofit.
11) What do I have to specify when ordering an ML2032 mortise lockset?
Four things decide the part. Cylinder type: standard conventional 6-pin L4, LC less cylinder, CL6 LFIC 6-pin less core, or CL7 LFIC 7-pin less core. Keying: KD keyed different or KA keyed alike. Lever design: Armstrong, Citation, Dirke (left or right hand), Essex, Lustra, Newport, Princeton, or Regis. And rose or escutcheon: A rose at 2-1/4 inch diameter, F rose at 2-7/8 inch diameter, or M or N escutcheon. Finish is a separate choice across fourteen options. There's also a free-text field for special cylinder or keying requirements if you're matching an existing system.
12) How do I get a locked/unlocked indicator or a vandal resistant version of an ML2000 mortise lock?
Status indicator trim is offered on the ML2000 Series in both sectional and escutcheon forms for locked/unlocked visibility. For high-abuse settings there's the ML2000VR vandal resistant option, stainless steel escutcheons with tapered edges and Torx pin tamper-resistant screws. Behavioral Health trim (BHSS/BLSS) is also in the family alongside the Museo and Vineyard designs. If an indicator is the main requirement and Corbin Russwin isn't mandated, the Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset for 1-3/4 inch doors.
13) Is a mortise lock like the ML2032 overkill compared to a cylindrical lock for a utility room?
For a utility or institutional door that gets hammered, no. The mortise case gives you a deadbolt and a latchbolt in one body, a 1 inch stainless deadbolt alongside the 3/4 inch latch, and the ML2032 has been cycle tested to 14.5 million cycles. A cylindrical lock has no deadbolt and puts all the security in the latch. The trade-off is prep: mortise needs a machined pocket in the door edge, cylindrical needs a 2-1/8 inch cross bore. If the door is already bored for cylindrical and you don't want to re-prep, a Schlage PC Series cylindrical is the different-prep route, but you give up the deadbolt.
14) I need electric latch retraction on a Corbin Russwin mortise lock, does the ML2032 do that?
Not the ML2032 itself, it's a straight mechanical lock with no electrical option. Motorized Electric Latch Retraction (MELR) is offered on the ML20900 series within the same ML2000 family, so staying with Corbin Russwin means moving to that series. If the brand is open, ZenSupply also carries the Command Access ML190 Series motorized mortise lock with field-selectable EL/EU operation on 24VDC, and the BEST 45HW wired electromechanical mortise lock running 12V or 24V.
15) What Grade 1 mortise lock should I use instead of the ML2032 if my door is thicker than 1-3/4 inches?
The ML2032 is specified at 1-3/4 inches standard, with optional thicknesses ordered specially. If you'd rather have a lock whose published range already covers a thicker door, the Hager 3800 Series runs 1-3/4 to 2-1/2 inches in the 3810E passage and 3850E office functions, and the Baldwin 6301 mortise lock body covers 1-3/4 inches and over on a 2-1/2 inch backset. Note the backset difference on the Baldwin, 2-1/2 inches versus the ML2032's 2-3/4, so the door prep is not interchangeable between them.
16) Can I standardize a whole building on one Corbin Russwin mortise lock body and change functions later?
That's how the ML2000 Series is set up. Twelve functions are configurable from a single ML2054 lockbody, so a facility can stock one body and set it to the function each opening needs rather than carrying a dozen part numbers. Trim across the series shares the same thru-bolted mounting, and the spacing is consistent, 3-5/8 inches (92mm) center to center from knob/lever to cylinder and 2-7/16 inches (62mm) from knob/lever to thumbturn. Keep in mind the F30 setting on the ML2032 is key-both-sides and cannot be used where free egress is required.
17) I need key control on both sides of a mortise-prepped door but not a lever lockset - what else works?
The ML2032 is a keyed double cylinder mortise lockset that retracts the latchbolt by key from either side. If the opening needs double-key control without a lever or knob operating the latch, the Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset in the 4870 Series - the same backset the ML2032 uses. The 4874 is a deadbolt only, so it provides no latching; the ML2032 carries a 3/4 inch latchbolt plus a deadlocking auxiliary latch in one case. Choose the 4874 where a separate latch or push/pull already handles closing the door, and the ML2032 where a single case must do both.
18) What is the electronic or keypad equivalent to a Corbin Russwin ML2032 mortise lock?
The ML2032 is a mechanical, non-electronic mortise lock keyed on both sides. If the facility wants credential or code-based access on a mortise-prepped door instead of cutting keys, the TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID on a 1-3/4 inch door, and the Schlage Electronics LEMD-GRW is a Grade 1 wireless mortise lock with a 125kHz proximity reader and mobile credentials, rated 3 hours fire. The Dormakaba E-Plex E5086 is a Grade 1 pushbutton and card mortise lock in a back to back configuration, which is the electronic parallel to keying both sides. All three change the function set, so confirm the opening's egress and code requirements before swapping.
19) What is the difference between ordering an ML2032 and ordering a BEST 45H mortise lock body?
The ML2032 ships as a complete keyed lockset - lockbody, trim, strike and a conventional 6-pin L4 keyway cylinder, with lever designs such as Armstrong, Citation and Lustra and A rose, F rose, M or N escutcheon trim. The BEST 45HCAC is a heavy duty mortise lock body with a public entrance function and field reversible operation, and the 45HCAINL is a heavy duty mortise lockbody with an intruder function - both are lock bodies, so trim and cylinder are separate lines on the order. Both the ML2032 and the BEST 45HCAC are field reversible for handing.
20) Which mortise locks look like an ML2032 substitute but are not keyed at all?
Several mortise units share the mortise case format with the ML2032 but carry no cylinder, so they cannot replace a keyed double cylinder function. The Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for a 1-3/4 inch door, the Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating, and the Hager 3810S and 3810E are 3800 Series Grade 1 passage mortise locks with a 2-3/4 inch backset - the 3810S with rose trim and the 3810E with escutcheon. The Schlage L0170 is a Grade 1 half dummy trim with no latch at all. Specify these only where the opening never needs to lock.
21) Will an Alarm Lock Trilogy mortise lock fit the same doors as an ML2032?
Check the door thickness first. The ML2032 is built for 1-3/4 inch doors, while the Alarm Lock DL2700CR classroom Trilogy T2, the DL3500CR Grade 1 classroom Trilogy and the DL4500 Grade 1 electronic mortise deadbolt are all listed for 1-5/8 inch to 1-7/8 inch doors. A 1-3/4 inch door falls inside that range, so thickness is compatible, but the function is not: the DL2700CR and DL3500CR are classroom function with keypad codes and the DL4500 is a deadbolt with a privacy keypad, none of which reproduce the ML2032 key-both-sides operation with both grips rigid.
22) If the opening needs electrified access control on a mortise prep, what replaces the ML2032?
The ML2032 is a mechanical lock, though the ML20900 series adds Motorized Electric Latch Retraction. For a wired electrified mortise on the same kind of prep, the BEST 45HW is a heavy duty wired electromechanical mortise lock with 12V and 24V operation, the Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever corridor mortise lock for a 1-3/4 inch door with request to exit and 12/24VDC, and the Command Access ML190 is a heavy-duty motorized mortise lock with field selectable EL/EU operation on 24VDC in a storeroom function. Each needs power transfer to the door, which a purely mechanical ML2032 does not.
23) Is a Codelocks CL2255 or Emtek mortise entrance set an acceptable alternative to an ML2032 on a commercial door?
Not for the same duty. The ML2032 is a Grade 1 commercial mortise lock. The Codelocks CL2255 is a medium duty electronic tubular mortise latch in the CL2000 Series with a brushed steel finish, a lighter class of hardware than a Grade 1 institution lock. The Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton and 3106 Manhattan mortise entrance locksets are dummy function, meaning they neither latch nor lock. On an institutional opening carrying a Grade 1 requirement, none of these substitute for the ML2032.
24) I need a privacy mortise lock for a restroom, not an institution function - what should I order?
The ML2032 is keyed on both sides for institution and utility use and is the wrong function for a restroom. For privacy on a mortise prep, the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt for a 1-3/4 inch door, and the Hager 3840S is a 3800 Series Grade 1 privacy mortise lock with a 2-3/4 inch backset covering 1-3/4 inch to 2 inch doors - the same 2-3/4 inch backset the ML2032 uses. For an office door that locks by key outside but stays free inside, the Hager 3850E is an office mortise lock with lever and escutcheon, non-keyed, 2-3/4 inch backset.
25) Can I use a cylindrical lock instead of the ML2032 to save on door prep?
Only on a new or re-prepped door. The ML2032 is a mortise lock requiring a mortise pocket in the door edge for a lockcase measuring 5-7/8 inches by 4 inches by 15/16 inch. The Schlage PC10 is a Grade 1 cylindrical lock for a 1-3/4 inch door with a passage function and rose trim, which uses a bored prep rather than a mortise pocket - so it is not an option on a door already mortised, and it is non-keyed, unlike the keyed ML2032. Where the door already carries a mortise pocket, stay within mortise-format hardware.
26) What finishes does the Corbin Russwin ML2032 come in, and can I match the stainless hardware already on my other doors?
Fourteen finishes, so matching an existing building standard is usually straightforward: 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 institutional work the two that come up most are 626 satin chrome and 630 satin stainless. Trim is brass or bronze substrate.
