Corbin Russwin ML2029-LL Hotel/Motel Mortise Lockbody Only - Grade 1, ANSI F15, Field Reversible

Commercial-Grade Hotel & Motel Mortise Lock Solution for High-Traffic Applications

The Corbin Russwin ML2029-LL is a Grade 1 mortise lockbody engineered for hotel and motel applications within the trusted ML2000 Series. Conforming to ANSI function F15, this lockbody allows the latchbolt to be operated by grip inside and by guest key or master key outside, while the deadbolt is controlled by thumbturn grip inside or by emergency key outside — with the emergency key capable of shutting out all other keys. Constructed of heavy-gauge steel with a 1" stainless steel deadbolt and patented Quick Reversible latchbolt, this lockbody is designed for 1-3/4" (44mm) door thickness and is field reversible for flexible installation. The ML2000 Series has been UL cycle tested above and beyond requirements, completing 14.5 Million Cycles (Verification ID: V875753), making it an ideal choice for demanding commercial, institutional, industrial, and government environments.

Corbin Russwin COR-ML2029-LL-626 – Frequently Asked Questions

1) What does ANSI F15 hotel function actually do on a guest room door?
F15 is the hotel/motel function: the latchbolt retracts by the inside grip at any time, and outside by guest key or master key. The deadbolt is thrown by the inside thumbturn grip, or by the emergency key from outside, and the emergency key shuts out all other keys. In practice that means a guest can deadbolt themselves in and only staff with the emergency key can get past it. The ML2029 is the lockbody only, so the trim, cylinder and thumbturn are ordered separately.
2) Do I have to order a left hand or right hand ML2029, or is it reversible in the field?
Order one part regardless of hand. The ML2029 uses Corbin Russwin's patented Quick Reversible latchbolt, so handing is changed in the field without opening the lock case. For a hotel retrofitting rooms that swing both ways, that means one lockbody on the shelf covers every opening.
3) What comes in the box with an ML2029 lockbody, and what else do I need to order to finish the door?
The ML2029 is the lock case alone. To complete a guest room opening you still need the trim (knob or lever set, with the thumbturn grip inside), the mortise cylinder, and the strike if you are not reusing one. Corbin Russwin's standard for the ML2000 is an ANSI straight lip strike, 4-7/8 x 1-1/4 x 1-1/8 inches lip to center. Trim spacing is fixed: 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) Can I use the ML2029 with my existing key system, or do I have to rekey the property?
It works with new or existing Corbin Russwin key systems, and it accepts most other manufacturers' cylinders, so a property already keyed to another brand can usually carry its keyway across. The Corbin Russwin standard cylinder for the series is brass, 6-pin L4 keyway, 0-bitted. Cylinders are ordered separately from the lockbody.
5) Is the ML2029 mortise lock approved for a fire rated hotel corridor door?
Fire rated and UL/cUL listed, tested to UL10C positive pressure. The rating covers 3-hour fire doors 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.
6) Will the ML2029 latch into the strike already in my frame?
It depends on the throw your current prep was cut for. The ML2029 latchbolt is a two-piece anti-friction unit measuring 5/8 x 1 inch with a 3/4 inch (19mm) throw, backed by a deadlocking auxiliary latch with 9/16 inch (14mm) effective throw. The deadbolt is one-piece stainless steel, 19/32 x 1-1/4 inch, with a full 1 inch (25mm) throw, so the frame needs a deadbolt pocket deep enough to take it. A standard ANSI 4-7/8 inch strike prep with a deadbolt cutout will take it; a strike cut only for a latch will not.
7) What is the closest equivalent to a Corbin Russwin ML2029 hotel mortise lockbody from another manufacturer?
The nearest cross-brand match is the Accentra 8800FL Series mortise lock body, which is also a Grade 1 mortise lock body with field reversible handing. The Corbin Russwin ML2029 is a Grade 1 mortise lockbody in the ML2000 Series with the hotel function and field reversible handing, so both land at the same ANSI/BHMA grade level and both let you set hand in the field rather than ordering left and right separately. The difference that matters when you cross brands is the trim and cylinder ecosystem: the ML2029 is an ML2000 Series body, so ML2000 trim and Corbin Russwin keying carry straight across, while the 8800FL body belongs to the Accentra 8800 platform. On a hotel retrofit where the existing doors are already ML2000, staying with the ML2029 keeps the prep, the trim, and the key system intact.
8) Can I substitute an Accentra 8800FL mortise lock body for a Corbin Russwin ML2029 on a guest room door?
Both are Grade 1 mortise lock bodies and both are field reversible, so at the grade and handing level they are peers. What decides the swap is function: the Corbin Russwin ML2029 is built to the hotel function, ANSI F15, where the latchbolt works by grip inside and by guest or master key outside while the deadbolt is thrown by inside thumbturn or by an emergency key that shuts out all other keys. A guest room opening depends on that shut-out behavior, so any substitute has to be ordered in the same hotel function and not simply as a Grade 1 body. Confirm the replacement body carries the hotel function before treating it as a drop-in, and confirm your cylinder and keyway plan, since the ML2029 accepts Corbin Russwin key systems and most other manufacturers' cylinders.
9) Should I buy a hotel function mortise lock or a standard entry mortise lock for guest rooms?
Pick the hotel function when guests need to shut out staff keys. The ML2029 F15 function gives the guest a thumbturn deadbolt inside that only an emergency key overrides, and the outside is guest key or master key. A standard office or entry mortise function has no shut-out behavior and no dedicated emergency key path, so it's the wrong choice for a rentable room but fine for back-of-house and offices. Both live in the same ML2000 case, so the mortise pocket, 2-3/4 inch backset and trim spacing stay the same if you standardize the building on one series.
10) How many door cycles is the Corbin Russwin ML2000 mortise lock tested to?
14.5 million cycles under UL cycle testing, Verification ID V875753, which is above the A156.13 Grade 1 requirement it also meets. For a guest room door getting opened dozens of times a day, that's the number that matters more than the grade alone.
11) What is a comparable Grade 1 mortise lock body from another brand if I am standardizing a property?
The Accentra 8800FL Series Grade 1 mortise lock body with field reversible handing is the closest peer we carry, and like the ML2029 it is a lock body sold on its own with handing reversible in the field. Where the Corbin Russwin differs is that its documented configuration is specifically the F15 hotel function on a 1-3/4 inch door at a 2-3/4 inch backset with a 1 inch deadbolt throw. Mortise bodies are not cross-brand drop-ins on trim or cylinder, so whichever you standardize on, keep the whole property on the one series.
12) Is the ML2029 an electrified lock, and can I get electric latch retraction for the ML2000 series?
The ML2029 is a mechanical lockbody with no electrical components. Motorized Electric Latch Retraction (MELR) is offered within the ML2000 family on the ML20900 series, so if you need latch retraction on an access-controlled opening, that is the series to specify rather than adding anything to this body.
13) I only need a Grade 1 mortise body for a plain office or storeroom door, not a hotel door. Is the ML2029 the right pick?
For an opening that does not need guest key and emergency key shut-out behavior, a general purpose Grade 1 mortise body such as the Accentra 8800FL Series is the simpler fit, since it covers the same Grade 1 mortise lock body category with field reversible handing without the hotel specific keying arrangement. The Corbin Russwin ML2029 is specifically the hotel function body, ANSI F15, with a deadbolt controlled by inside thumbturn or emergency key. On an office or storeroom door that behavior is capability you are not going to use. Where the ML2029 still earns the spot is a mixed property that is standardizing on ML2000 Series bodies across guest rooms and back of house, because keeping one series keeps trim, prep, and keying common across the building.
14) Does ordering a Grade 1 mortise lock body get me a complete working lock?
No. The Corbin Russwin ML2029 is a mortise lockbody only, and the Accentra 8800FL Series is likewise a mortise lock body, so in both cases you are buying the case that goes into the door pocket, not a finished assembly. Lever or knob trim and a cylinder are separate lines on the order. The ML2029 body is non-keyed as supplied and takes a cylinder separately, which is what lets it run on a new or existing Corbin Russwin key system or accept most other manufacturers' cylinders. If you are replacing a failed case in a door where the trim and cylinder are still good, that is exactly the part you want; if you are hardware-ing a bare door, plan the trim and cylinder alongside it.
15) What finishes does the ML2029 hotel mortise lockbody come in?
Fourteen finishes, covering brass, bronze, nickel, chrome and stainless: 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. On a lockbody the visible finish is the armored front, which is wrought brass, bronze or stainless at 8 x 1-1/4 inches, so match it to the trim and strike already on your other doors.
