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

1) How does the Corbin Russwin ML2029 hotel function actually work for a guest room door?
It runs ANSI F15 hotel function. The latchbolt retracts by the inside grip and by guest key or master key from outside, and the outside grip stays rigid at all times. The 1 inch stainless deadbolt throws by inside thumbturn, and only an emergency key releases it from the corridor side, so a guest can secure the room and staff can still get in for life safety.
2) Will the ML2029 mortise lock fit a 1-3/4 inch door with a 2-3/4 inch backset prep?
Yes. The ML2029 is built for 1-3/4 inch (44mm) doors on a 2-3/4 inch (70mm) backset, which is the standard commercial mortise prep. 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. Thicker doors are available as an option.
3) Do I have to order the ML2029 handed, or can it be reversed in the field?
Order it and re-hand it on site if needed. The lock is handed but uses a Quick Reversible latchbolt, so the handing flips without opening the lock case. One exception on trim: the Dirke (DS) lever is offered as a specific left hand or right hand lever, so that choice is made at order time.
4) Will the ML2029 latch into the strike already in my frame?
Depends what is in the frame now. The lock ships with an ANSI straight lip strike measuring 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center, and the latchbolt throws 3/4 inch (19mm) with a 9/16 inch deadlocking auxiliary latch. If your frame already has a standard ANSI 4-7/8 inch strike cutout, it lines up. Note the deadbolt throws a full 1 inch, so the strike must also have the deadbolt pocket.
5) Can I key the ML2029 into my existing hotel master key system?
Yes. The ML2000 Series works with new or existing Corbin Russwin key systems and accepts most other manufacturers' cylinders. Standard supply is a conventional 6-pin brass cylinder in the L4 keyway, 0-bitted. If you are on an interchangeable core system, order CL6 for LFIC 6-pin less core or CL7 for LFIC 7-pin less core, or LC to take the lock less cylinder entirely and use your own.
6) What is the closest Grade 1 mortise alternative to the Corbin Russwin ML2029 for a guest room door if I want an electronic credential instead of a mechanical hotel key?
The ML2029 is a mechanical Grade 1 hotel-function mortise lock, keyed with a conventional 6-pin L4 keyway cylinder and no electronics. If the guest room is moving to credentials, the Dormakaba LX-I-M002 Saffire is an electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2, and the TownSteel FME-2000 is a Grade 1 heavy duty mortise lockset with RFID technology in classroom function. The ML2029 keeps the thumbturn deadbolt with emergency key override on a fully mechanical platform; the RFID units move access control to a credential system.
7) I need a mortise lock for a back-of-house door, not a guest room - what should I use instead of the ML2029 hotel function?
The ML2029 runs ANSI F15 hotel function, where the outside grip is always rigid and entry is by guest or master key with a separate deadbolt by thumbturn inside or emergency key outside. That behavior is wrong for a service or stock room. For storeroom duty, the Accentra 8805FL is a Grade 1 storeroom mortise lock, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option. For an office or entrance door, the Cal-Royal NM8050 is a Grade 1 office/entrance mortise lockset with auxiliary deadlatch.
8) Which mortise lock should I spec if the guest room door has to tie into an access control panel?
The ML2029 is a non-electronic mechanical lockset, so it does not interface with a panel. For wired control, the BEST 45HW is a wired electromechanical mortise lock with 12V/24V operation, the Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock, keyed outside, with request to exit, at 12/24VDC on a 1-3/4 inch door, and the Command Access ML190 is a heavy-duty motorized mortise lock in storeroom function with field selectable EL/EU operation at 24VDC.
9) What do I need to specify when ordering the ML2029 besides finish?
Four decisions. Cylinder type is required: standard conventional 6-pin L4, LC less cylinder, CL6 LFIC less core, or CL7 LFIC less core. Keying is keyed different (standard) or keyed alike if you want a bank of locks on one key. Then lever style, from Armstrong, Citation, Dirke, Essex, Lustra, Newport, Princeton or Regis, and trim: A rose (2-1/4 inch dia.), F rose (2-7/8 inch dia.), M escutcheon or N escutcheon.
10) Is the ML2029 durable enough for high traffic guest room doors?
The ML2000 Series lockcase is heavy-gauge steel and has been UL cycle tested to 14.5 million cycles (Verification ID V875753), well past the requirement, and it holds ANSI/BHMA A156.13 Series 1000 Grade 1 for both operational and security grade. Trim is thru-bolted for alignment and added resistance to being pulled off.
11) I need a mortise lock for a classroom or storeroom, not a hotel room. Is the ML2029 the right one?
No. The ML2029 is the hotel/motel function, with a rigid outside lever and emergency key deadbolt override, which is not what you want on a classroom or a supply room. For storeroom function look at the Accentra 8805FL Grade 1 storeroom mortise with Arcadia lever or the Cal-Royal NM8080 Grade 1 storeroom mortise. For classroom, the Cal-Royal NM8070 Grade 1 classroom mortise is the mechanical equivalent.
12) My doors are 1-5/8 to 1-7/8 inch. Will the ML2029 work?
Standard ML2029 supply is set up for 1-3/4 inch (44mm) doors, with optional thicknesses available on request, so specify the thickness rather than assuming the stock build covers it. If you are buying off the shelf for a 1-5/8 to 1-7/8 inch range, Alarm Lock's Trilogy DL2700CR and DL3500CR Grade 1 electronic mortise locks are listed for that span, though those are classroom function rather than hotel.
13) How far apart are the lever and cylinder holes on the ML2029 door prep?
Center to center from the knob/lever to the cylinder is 3-5/8 inches (92mm), and lever to thumbturn is 2-7/16 inches (62mm). Those two dimensions decide whether the escutcheon or rose set covers an existing prep, so check them against the holes already drilled before committing to trim.
14) What looks like a mortise hotel lock but will not work on a guest room door?
Watch for dummy and passage mortise trim. Emtek 3102 Memphis, 3104 Hamilton and 3106 Manhattan are dummy mortise entrance locksets, and the Schlage L0170 is a Grade 1 non-keyed half dummy trim - none of them latch or lock. Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock, and Falcon MA101 is a Grade 1 heavy duty passage mortise lock, both of which latch but never secure. The ML2029 is keyed, single cylinder, with a hotel function that adds a deadbolt operated by inside thumbturn or emergency key outside.
15) What is the difference between the ML2029 and the Baldwin 6301 entry/apartment mortise lock for a multi-family unit door?
The Baldwin 6301 is an entrance/apartment function mortise lock body with a 2-1/2 inch backset, offered knob by knob or, as the 6301LS, lever by lever, for doors 1-3/4 inch and over. The ML2029 is a Grade 1 hotel function lever lockset on a 2-3/4 inch backset with a 1 inch stainless deadbolt and emergency key override from outside. If the building operates on master keys with staff override, hotel function is the behavior you want; apartment function does not provide the emergency key override.
16) For a healthcare or behavioral health door, is the ML2029 the right choice or should I look elsewhere?
The ML2029 is a hotel function lever lockset and the ML2000 platform does offer Behavioral Health trim designs, but the function itself is guest room operation. Where the requirement is anti-ligature hardware, the TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in passage function and the MRX-A-01 is a ligature resistant arch trim mortise lockset, both for 1-3/4 inch doors. Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant in satin stainless.
17) Is there a simpler non-keyed mortise lock I can use on interior guest room bathroom doors instead of the ML2029?
Yes. The ML2029 is a keyed hotel function lockset and is more hardware than a bath door needs. Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset for doors 1-3/4 to 2 inch, and Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors. For a closet or hall door, Hager 3810S is a Grade 1 passage mortise lock with rose and Hager 3810E is the same function with escutcheon.
18) What finishes does the ML2029 hotel lockset come in for matching existing guest room hardware?
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. Base material is brass or bronze.
19) Can I use one ML2000 lockbody and change functions later across a building?
Yes, within the multi-function platform. Corbin Russwin's ML2054 lockbody is configurable to 12 functions, so a facility standardizing on the ML2000 Series can stock fewer bodies and change function in the field. The ML2029 itself is the hotel/motel F15 configuration on that same platform, with a 2-3/4 inch backset and standard ANSI strike shared across the series.
20) Is there a vandal resistant version for rough properties?
Yes, the ML2000VR configuration uses vandal-resistant stainless steel escutcheons with tapered edges and Torx pin tamper-resistant screws. There are also behavioral health trims (BHSS/BLSS) in the series for psychiatric and detention-adjacent spaces, plus status indicator options on sectional and escutcheon trim if staff need to read locked/unlocked from the corridor.
21) I need a lock body only to rebuild existing mortise preps - is the ML2029 the right buy?
The ML2029 is supplied as a complete Grade 1 hotel lever lockset with lever, rose or escutcheon trim and a conventional 6-pin L4 cylinder. If you only need a case, the BEST 45H is a heavy duty mortise lock body in public entrance function with field reversible operation, and the 45HCA is a heavy duty mortise lockbody in intruder function. Those are bodies, so existing trim and cylinders have to carry over.
