Corbin Russwin ML2069-KEYED Mortise Institution Privacy Lever Lockset Grade 1, ANSI F26, Field Reversible

Commercial-Grade Institutional Privacy Mortise Lock for High-Traffic Applications

The Corbin Russwin ML2069-KEYED is a Grade 1 mortise institution privacy lever lockset from the ML2000 Series, engineered for demanding commercial, institutional, industrial, and government environments. Designed to ANSI function F26, this lock allows latchbolt retraction by grip from either side, except when the outside is locked by the thumbturn inside — with the key outside retracting the latch at all times, even when the thumbturn is held in the locked position. Constructed of heavy-gauge steel with a 1" stainless steel deadbolt and a 3/4" latchbolt, the ML2069 is built for 1-3/4" (44mm) standard door thickness and features a field-reversible handing design. The ML2000 Series has been UL cycle tested above and beyond requirements, completing over 14.5 million cycles (Verification ID: V875753), making it an outstanding choice for offices, schools, hospitals, hotels, and other high-use facilities.

Corbin Russwin COR-ML2069-NSA-626 – Frequently Asked Questions

1) Will the Corbin Russwin ML2069 mortise lock fit a 1-3/4 inch door with a 2-3/4 inch backset prep?
Yes. The ML2069 is built for 1-3/4 inch (44mm) standard door thickness with a 2-3/4 inch (70mm) backset, which is the standard commercial mortise prep. The lock case measures 5-7/8 x 4 x 15/16 inches and the armored front is 8 x 1-1/4 inches. Optional door thicknesses are available if your doors are heavier than standard.
2) Do I need to order the ML2069 handed, or can I re-hand it in the field?
Order it and re-hand on site. The ML2069 uses the patented Quick Reversible latchbolt, so handing is changed without disassembling the lock case. One exception on trim: the Dirke (DS) lever is offered as a specific left hand or right hand lever, so that lever choice is handed even though the lock body is not.
3) Will the ML2069 latch into the existing strike and frame prep on my doors?
It ships with a wrought brass, bronze or stainless ANSI straight lip strike, 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center. The latchbolt is a two-piece anti-friction unit with a 3/4 inch (19mm) throw, plus a 9/16 inch deadlocking auxiliary latch and a 1 inch throw stainless deadbolt. If your frames already carry a standard 4-7/8 ANSI strike box, the strike drops straight in; the deadbolt needs the deadbolt pocket in that ANSI prep to be open.
4) Can I key the ML2069 into our existing Corbin Russwin master key system, or use small format cores?
Yes on both counts. The ML2069 works with new or existing Corbin Russwin key systems and accepts most other manufacturers' cylinders. Standard is a conventional brass 6-pin L4 keyway cylinder, 0-bitted. You can also order it LC (less cylinder) to supply your own, or CL6 / CL7 for a large format interchangeable core housing less core. Keying is specified keyed different or keyed alike, with keyed different as standard.
5) Is the ML2069 approved for a 3-hour fire rated opening?
Yes. The ML2000 Series is UL/cUL listed and UL10C positive pressure rated for 3-hour fire doors up to 4 ft x 10 ft single or 8 ft x 10 ft pair. It is also ANSI/BHMA A156.13 Series 1000 Grade 1 for both operational and security, meets ADA A117.1, and carries California State Fire Marshal and windstorm/hurricane certification.
6) What is the closest Grade 1 privacy mortise lock to the Corbin Russwin ML2069 if I need a standard bed/bath privacy function instead of institution privacy?
The ML2069 is an institution privacy function where the latchbolt works by grip from either side except when the outside is locked by the inside thumbturn, and the key outside retracts the latch at all times. If you want a conventional privacy lock rather than that institutional behavior, the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors, and the Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset for 1-3/4 to 2 inch doors. Both are non-keyed privacy sets, so you lose the outside key override the ML2069 provides.
7) I need a Grade 1 mortise lock for a patient room or behavioral health door instead of the ML2069 - what else should I look at?
The ML2069 is a lever-handle institution privacy mortise lock and is offered with Behavioral Health trim in the ML2000 Series. If the opening calls for a push/pull or anti-ligature trim instead of a lever, the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant in satin stainless steel, and TownSteel offers the MRX-L-01 anti-ligature lever and MRX-A-01 arch trim, both Grade 1 heavy duty mortise locksets for 1-3/4 inch doors. Note that all three are passage function and provide no privacy locking, where the ML2069 locks the outside lever by inside thumbturn.
8) Which mortise lock should I use if the opening needs electric lock/unlock or latch retraction rather than the mechanical ML2069?
The ML2069 itself is mechanical, though the ML2000 platform offers Motorized Electric Latch Retraction on the ML20900 series. Cross-brand, the Schlage L9092EU 03A is a heavy duty electric lock/unlock outside lever mortise lock, keyed outside, with request to exit and 12/24VDC for 1-3/4 inch doors, the Command Access ML190 Series is a heavy-duty motorized storeroom mortise lock with field selectable EL/EU operation on 24VDC, and the BEST 45HW is a heavy duty wired electromechanical mortise lock running 12V or 24V. All require power to the door, which the ML2069 does not.
9) We want an intruder or lockdown function for a classroom instead of the ML2069 institution privacy - what are the options?
The ML2069 locks the outside lever from an inside thumbturn, but the inside lever or closing the door releases it, which is not a lockdown hold. For a dedicated lockdown, the BEST 45HCA is a heavy duty mortise lockbody with intruder function, and the TownSteel FME-4000 Series is a Grade 1 heavy duty electronic intruder classroom mortise lockset with RFID for 1-3/4 inch doors. The TownSteel FME-2000 Series is the Grade 1 classroom RFID version without the intruder feature.
10) What do I have to specify when ordering an ML2069 lockset?
Four decisions. Cylinder type: standard conventional 6-pin L4, LC less cylinder, CL6 LFIC 6-pin less core, or CL7 LFIC 7-pin less core. Keying: keyed different or 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, or M or N escutcheon. Finish runs from 605 bright brass through 626 satin chrome, 630 satin stainless and BSP black suede powder coat.
11) Is there enough room on the door face for the lever and the cylinder and thumbturn?
Trim spacing on the ML2069 is 3-5/8 inches (92mm) center to center from knob/lever to cylinder, and 2-7/16 inches (62mm) from knob/lever to thumbturn. Those are the hole centers your door prep has to match, and they are the same ML2000 spacings across the sectional trims, so an A rose, F rose, M or N escutcheon all land on the same bores.
12) How durable is the ML2069 for a high traffic corridor or dorm door?
The lock case is heavy-gauge steel with a one-piece stainless steel deadbolt, and the ML2000 Series has been UL cycle tested to over 14.5 million cycles (Verification ID V875753), well past the Grade 1 requirement. That is the platform to standardize on for schools, hospitals, hotels and government buildings where the same opening gets hit thousands of times a week.
13) What is the difference between the ML2069 and a classroom or storeroom mortise lock?
Function, not build. The ML2069 locks the outside lever from an inside thumbturn and unlocks when the inside lever is used or the door closes, which suits patient, exam and utility rooms where someone inside needs temporary privacy but staff need key access. A storeroom function such as the Accentra 8805FL or Cal-Royal NM8080 keeps the outside lever locked at all times with key entry only. A classroom function like the Cal-Royal NM8070 is locked and unlocked by key from outside. Pick by who controls the locking and from which side.
14) Is a storeroom mortise lock a substitute for the ML2069?
No. A storeroom lock keeps the outside lever locked at all times and is released only by key, while the ML2069 lets the latchbolt be operated by grip from either side unless the inside thumbturn locks the outside. If storeroom is actually the function you want, the Accentra 8805FL is a Grade 1 storeroom mortise lock with an Arcadia lever in 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.
15) Can I use an electronic mortise lock instead of the ML2069 to get privacy plus credential access?
The ML2069 is a mechanical lock with no electronic option, keyed with a conventional 6-pin L4 keyway cylinder. If you want privacy with electronic access control, the Schlage CO-100-MS-40-KP is a Grade 1 heavy duty standalone electronic mortise lock in privacy function with a keypad reader for 1-3/4 inch doors, and the Schlage LEBMB-ADD is a mobile-enabled mortise lock offering privacy, office and apartment functions with a push button and LED on a 3-hour fire rating at Grade 2. Confirm the electronic model's power and credential scheme with your integrator before swapping.
16) If the opening just needs a latch with no locking, what is the simpler alternative to the ML2069?
The ML2069 carries a keyed cylinder and a thumbturn for institutional privacy, which is more lock than a corridor or closet door needs. For plain latching, the Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating, the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, and Hager offers the 3810S passage mortise lock with rose or the 3810E with escutcheon, both on a 2-3/4 inch backset for 1-3/4 to 2-1/2 inch doors. All match the ML2069's 2-3/4 inch backset in the Hager case, but none accept a key.
17) My doors are 1-5/8 to 1-7/8 inch thick - does the ML2069 fit, or do I need something else?
The ML2069 is built for 1-3/4 inch standard door thickness, with optional thicknesses available on request. If you need a lock rated across a 1-5/8 to 1-7/8 inch range out of the box, the Alarm Lock Trilogy line covers it: the DL2700CR and DL3500CR are Grade 1 electronic classroom mortise locks for 1-5/8 to 1-7/8 inch doors, and the DL4500DB is a Grade 1 electronic mortise deadbolt over the same thickness range. Those are keypad-credentialed rather than thumbturn privacy, so the operation differs from the ML2069.
18) What is the difference between the ML2069 and a mortise deadbolt like the Sargent 4874?
The ML2069 is a complete lever lockset: a 3/4 inch throw anti-friction latchbolt plus a 1 inch stainless steel deadbolt in one heavy-gauge steel case, with lever trim on both sides. The Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset with no latch or lever, and the Kaba Ilco 185 Series is a no-handing mortise deadbolt as well. Deadbolt-only bodies are used alongside a separate latching device, not in place of a lockset like the ML2069.
19) We need a dormitory or corridor function rather than institution privacy - what Grade 1 mortise lock covers that?
The ML2069 locks the outside lever by an inside thumbturn and unlocks when the inside lever is operated or the door closes, which is institutional privacy. For a dormitory arrangement, the Sargent 7925 is a Grade 1 heavy duty corridor/dormitory exit function mortise lock in the 7900 Series with rose trim and a single cylinder deadbolt. Compare the trim styles carefully, since the ML2069 is offered with A and F roses as well as M and N escutcheons.
20) Is a mortise lock body like the BEST 45H an equivalent to the ML2069?
Not as a one-for-one order. The BEST 45H is a heavy duty mortise lock body in public entrance function with field reversible operation, and the 45HCA intruder version is also sold as a lockbody - those are cases without trim. The ML2069 ships as a complete lever lockset with a chosen lever design, rose or escutcheon, and finish, and it is field reversible as well. If you are replacing only a failed case behind existing trim, a lockbody is the right call; if you are trimming a bare door, the ML2069 covers it.
21) Will a Baldwin 6301 or 6310 mortise lock work in the same prep as the ML2069?
No. The ML2069 is machined for a 2-3/4 inch backset with a heavy-gauge steel case 5-7/8 by 4 by 15/16 inch and an 8 by 1-1/4 inch armored front. The Baldwin 6301 entry/apartment and 6310 entry/storeroom mortise bodies are 2-1/2 inch backset products, so the cylinder and knob or lever centerlines land differently in the door. Treat them as separate preps rather than drop-in swaps.
22) We need the office or entrance function on some doors and the ML2069 on others - can we stay with one brand of mortise lock?
The ML2069 is built on the ML2054 lockbody, which is configurable to 12 functions from a single case, so other ML2000 Series functions share the same 2-3/4 inch backset and case footprint across a facility. If you are mixing brands instead, the Cal-Royal NM8050 is a Grade 1 office/entrance mortise lockset with auxiliary deadlatch for 1-3/4 inch doors and the Hager 3850E is a Grade 1 non-keyed office mortise lock with lever and escutcheon on a 2-3/4 inch backset. Standardizing on one platform keeps door prep and keying consistent.
23) Is a cylindrical lock like the Schlage PC10 an option if the door is not prepped for a mortise pocket?
The ML2069 requires a mortise pocket sized for a 5-7/8 by 4 by 15/16 inch case with an 8 by 1-1/4 inch armored front on a 2-3/4 inch backset. If the door only has a cylindrical bore, the Schlage PC10 is a Grade 1 non-keyed passage cylindrical lock with rose for 1-3/4 inch doors in the PC Series. It is passage only, so it gives you no privacy locking and no key, and the two preps are not interchangeable without modifying the door.
24) Can I see at a glance whether the room is occupied?
Yes, status indicator options showing locked/unlocked are available on the ML2000 Series with both sectional and escutcheon trim, which on a patient or restroom door saves staff trying the lever. If you specifically want an indicator classroom security lock from another brand, the Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset for 1-3/4 inch doors with an ANSI strike and a steel escutcheon measuring 8-1/2 x 2-3/4 x 7/16 inches.
25) What are the ML2069 trim and lever parts made of, and which finishes hold up outdoors or in a wet area?
Trim substrate is brass or bronze, with the armored front and strike offered in wrought brass, bronze or stainless steel. For wash-down, coastal or heavy-cleaning environments, specify a stainless finish, 629 bright stainless steel or 630 satin stainless steel. 626 satin chrome is the usual institutional default, and BSP black suede powder coat is there if the spec calls for black.
26) I only need to replace the thumbturn on an institutional privacy door - is a Sargent thumbturn compatible with the ML2069?
The ML2069 uses a thumbturn on the inside spaced 2-7/16 inch center to center from the lever, with 3-5/8 inch from lever to cylinder, and it is supplied as a complete Corbin Russwin lockset. Sargent sells the 130KB standard mortise thumbturn for the 8200 Series and the 130W thumbturn with round backplate for the 7800 Series. Those are matched to Sargent lock bodies and their own spacing, so verify the hole pattern in the door before ordering one against a Corbin Russwin case.
27) Is the Schlage L0170 an alternative to the ML2069?
Only for a different purpose. The Schlage L0170 is a Grade 1 heavy duty half dummy trim in the L Series, a non-keyed dummy for 1-3/4 inch doors with no latch. The ML2069 is a working Grade 1 institution privacy mortise lockset for 1-3/4 inch doors with a keyed cylinder. Order a dummy only where the leaf does not need to latch.
