Corbin Russwin ML2069-LL Institutional Privacy Mortise Lockbody, Grade 1, ANSI F26, Field Reversible

Heavy-Duty Institutional Privacy Mortise Lock for High-Traffic Commercial Applications

The Corbin Russwin ML2069-LL is a Grade 1 Institutional Privacy Mortise Lockbody from the ML2000 Series, engineered to meet the demanding requirements of commercial, institutional, industrial, and government environments. Conforming to ANSI function F26, this lockbody allows latchbolt retraction by grip from either side except when the outside is locked by the thumbturn inside; operating the inside grip or closing the door automatically unlocks the outside grip. Constructed of heavy-gauge steel with a 1" stainless steel deadbolt and Corbin Russwin's patented Quick Reversible latchbolt, the ML2069-LL is designed for 1-3/4" (44mm) door thickness and is field reversible for flexible installation. The auxiliary latch deadlocks the latchbolt for added security, and a key outside retracts the latch at all times, even when the thumbturn is held in the locked position.

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

1) What does the Corbin Russwin ML2069 institutional privacy function actually do on a patient room door?
ANSI F26 works like this: grip either side retracts the latch, except the outside is locked by the inside thumbturn. Turning the inside grip, or simply closing the door, automatically unlocks the outside again, so nobody gets shut out permanently. Staff aren't locked out either, since a key outside retracts the latch at all times, even while the thumbturn is being held in the locked position. That last behavior is why this function ends up on psychiatric, behavioral health, and hospital doors rather than a plain privacy lock.
2) Will the ML2069 mortise lock fit a 1-3/4 inch door with a 2-3/4 inch backset?
Yes, 1-3/4 inch (44mm) is the standard door thickness for the ML2069, and the backset is 2-3/4 inches (70mm), which is the usual commercial mortise backset. The lockcase itself measures 5-7/8 x 4 x 15/16 inches, so the existing mortise pocket has to take that case. Other door thicknesses are available as an option.
3) What exactly comes in the box with the ML2069-LL, and what else do I have to order to finish the door?
This is the lockbody only. The case, latchbolt, deadbolt, and auxiliary latch are in it, but the trim (levers or knobs, roses or escutcheons) is a separate order, and so is the cylinder if the opening needs one. Corbin Russwin trim options run from Museo and Vineyard designs through Behavioral Health BHSS and BLSS trim, plus status indicator trim for locked/unlocked visibility on sectional and escutcheon designs. Spacing for laying out the trim: 3-5/8 inches (92mm) center to center from knob or lever to cylinder, and 2-7/16 inches (62mm) from knob or lever to thumbturn.
4) Do I have to specify handing when ordering the Corbin Russwin ML2069, or can it be reversed in the field?
Field reversible. The patented Quick Reversible latchbolt lets you re-hand the lock without taking the case apart, so a lock pulled for the wrong hand doesn't become a return. Useful if you're stocking one lockbody for a run of openings that swing both ways.
5) Will the ML2069 latch into the strike that is already in my frame?
Depends on what's in the frame now. The latchbolt throws 3/4 inch (19mm) and the deadbolt throws a full 1 inch, so the strike box has to be deep enough for both. Corbin Russwin ships it against an ANSI straight lip strike, 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center. If your existing frame has a standard ANSI 4-7/8 inch strike prep, it drops in; a smaller T-strike or a shallow box won't take the 1 inch deadbolt.
6) Can I put the Corbin Russwin ML2069 on a 3-hour fire rated door?
Yes. The ML2000 Series mortise locks are UL and cUL listed to UL10C positive pressure, rated for 3-hour fire doors up to 4 x 10 feet single or 8 x 10 feet pair. They also carry ADA A117.1, California State Fire Marshal, and windstorm/hurricane certification, which is the paperwork set most healthcare and school specs are looking for.
7) What is the Accentra equivalent of the Corbin Russwin ML2069 mortise lock body?
The Accentra 8800FL Series mortise lock body is the closest cross-brand counterpart. Both are Grade 1 mortise lock bodies sold as the lock case alone, and both are field reversible for handing, so either can be set to a left- or right-hand opening without ordering hand-specific stock. The ML2069 is specifically the institutional privacy function (ANSI F26), so when you cross to the 8800FL Series you have to specify the matching function code on the Accentra side rather than assuming the body carries it.
8) Will an Accentra 8800FL lock body drop into a door prepped for a Corbin Russwin ML2069?
Do not assume it will. Both are Grade 1 mortise bodies and both are field reversible, but each manufacturer sets its own case dimensions, cylinder and thumbturn spacing, and armored front. The ML2069 case is 5-7/8 inch by 4 inch by 15/16 inch with 2-3/4 inch backset, 3-5/8 inch center-to-center from lever to cylinder and 2-7/16 inch from lever to thumbturn. Measure the existing mortise pocket and the trim hole pattern against those numbers before crossing brands; if the pocket was cut for Corbin Russwin, staying with the ML2069 avoids re-prepping the door.
9) Is the ML2069 Grade 1 heavy enough for a hospital corridor or a school door?
It meets ANSI/BHMA A156.13 Series 1000 at Operational and Security Grade 1, the top mortise grade, and Corbin Russwin cycle tested it to 14.5 million cycles under UL Cycle testing. Construction is heavy gauge steel case with a one-piece stainless steel deadbolt. For high-traffic institutional openings, that cycle number is the figure worth quoting into a spec.
10) The ML2069 is a privacy function, so does it take a cylinder, and will my existing Corbin Russwin keys work?
It's a non-keyed function, but it does accept a cylinder outside for the key override that retracts the latch even against the thumbturn. It can be used with new or existing Corbin Russwin key systems and accepts most other manufacturers' cylinders, so a building already keyed on another system isn't automatically out. Corbin Russwin's standard is a brass 6-pin L4 keyway, supplied 0-bitted.
11) Should I use an institutional privacy mortise lock or a standard privacy lock on a patient or resident room?
Standard privacy locks assume the person inside should control access and that staff can wait. Institutional privacy assumes the opposite: the occupant gets privacy from the inside thumbturn, but the door releases itself the moment the inside grip is used or the door closes, and staff can always key in from outside regardless of the thumbturn. That's the behavior behavioral health, psychiatric, and hospital specs call for. If the opening is an office or a restroom where nobody needs override authority, a plain privacy function is the simpler order.
12) Is there a Grade 1 mortise lock body from another brand I can substitute if I am not tied to Corbin Russwin?
The Accentra 8800FL Series Grade 1 mortise lock body is the closest cross-brand equivalent we carry, and it's also field reversible for handing. Same class of part, lock body only, no trim. Where the Corbin Russwin makes more sense is a building already standardized on Corbin Russwin keying or ML2000 trim, since the ML2069 works with existing Corbin Russwin key systems and shares the ML2000 trim range across openings.
13) Can this Corbin Russwin lock be electrified for access control or electric latch retraction?
No, the ML2069 is a mechanical, non-electronic lockbody. Motorized Electric Latch Retraction (MELR) is offered on the ML20900 series, not on this one, so if the opening needs latch retraction on a card reader or a fire alarm interface, you're ordering out of that series instead.
14) I need a keyed mortise lock, not a privacy function. Is the ML2069 the right body?
No. The ML2069 is a non-keyed institutional privacy body: the outside is locked by the inside thumbturn, and operating the inside grip or closing the door releases it. For an opening that has to be locked and unlocked by key from the corridor side, order a keyed function from the same ML2000 Series instead so the case, 2-3/4 inch backset and trim prep stay identical to the rest of the doors.
15) What looks like a substitute for the ML2069 but is not?
A standard bathroom or bedroom privacy mortise lock. Both carry the word privacy, but the ML2069 is the ANSI F26 institutional privacy function built for patient rooms and behavioral health openings: a key retracts the latch from outside at all times, even while the thumbturn is held in the locked position, and the auxiliary latch deadlocks the latchbolt. A conventional privacy lock with a simple emergency release does not give staff that key override. The other mismatch is scope - the ML2069 ships as the lock body only, so trim, cylinder and strike are separate lines on the order.
16) I need an electrified mortise lock for an access control opening. Does the ML2069 work?
The ML2069 is a mechanical body with no electrical components, so it does not tie into an access control system on its own. For an electrified opening, move to the ML20900 series within the same ML2000 family, which offers Motorized Electric Latch Retraction; that keeps the same case platform and 2-3/4 inch backset prep as the mechanical bodies on the rest of the doors.
17) Why does the ML2069 have an auxiliary latch, and does it change the door prep?
The auxiliary latchbolt deadlocks the main latchbolt so the latch can't be shimmed or carded while the door is closed, which matters on a privacy function where the outside grip may be locked. Its effective throw is 9/16 inch (14mm). It rides in the same armored front (8 x 1-1/4 inches, wrought brass, bronze, or stainless), so no separate prep beyond the standard mortise pocket and front cutout.
18) What finishes does the Corbin Russwin ML2069 lockbody come in?
Fourteen: 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. If you're matching a building already standardized on 626 satin chrome or 630 satin stainless, those are the two that dominate institutional work.
19) Does the door close harder with the ML2069, and what is the latchbolt made of?
Less force, not more. The latchbolt is a two-piece mechanical design with an anti-friction insert, which cuts the drag as the bolt hits the strike lip, so the door latches with a lighter push. That matters on healthcare openings running closers tuned down for ADA opening force. The bolt measures 5/8 x 1 inches with a 3/4 inch (19mm) throw.
20) Does the ML2069 have to be ordered handed, or can one part number cover both hands like the Accentra 8800FL body?
Neither one has to be stocked in two hands. The Accentra 8800FL Series mortise lock body is field reversible, and so is the ML2069 - its patented Quick Reversible latchbolt lets you re-hand the lock without opening the lock case. For a facility standardizing a service stock across mixed-hand openings, either brand gives you one body that covers both swings.
