Corbin Russwin COR-ML2024-LL-626 – Frequently Asked Questions

1) Does the Corbin Russwin ML2024 come with the trim, lever and cylinder, or just the lock case?
Lock case only. The ML2024-LL is sold as a mortise lockbody, so the lever or knob trim, the escutcheon or sectional plate, and the cylinder are separate line items you specify and order alongside it. The body does ship with the ANSI straight lip strike, measuring 4-7/8 x 1-1/4 x 1-1/8 inches lip to center. Plan the order as: body, trim design, and a 6-pin cylinder.
2) What does ANSI F21 entrance/storeroom function actually do at the door?
F21 is the entrance/storeroom function: the outside lever or knob is locked at all times and a key retracts the latchbolt for entry, while the inside is always free for egress. The ML2024 also carries a 1 inch stainless steel deadbolt with a 1 inch throw in the same case, so you get life safety and security in one door prep rather than adding a separate deadlock above the lock. That is why it lands in tenant entry doors, stockrooms, IT closets and mechanical rooms.
3) Will the ML2024 latch into the strike that is already in my frame?
The latchbolt throws 3/4 inch (19mm) and the auxiliary deadlatch has a 9/16 inch effective throw, with the deadbolt throwing a full 1 inch. If your frame is prepped for an ANSI strike, the supplied one measures 4-7/8 x 1-1/4 x 1-1/8 inches lip to center and drops into that cutout. A frame with a non-ANSI or T-strike prep needs the frame reworked, because the 1 inch deadbolt has to have a matching deadbolt pocket, not just a latch keeper.
4) Can I use the ML2024 on a fire rated door?
Yes. The ML2000 Series is UL/cUL listed and UL10C positive pressure rated, good for a 3-hour fire door up to 4 by 10 feet single or 8 by 10 feet pair. It also meets ADA A117.1, carries California State Fire Marshal listing and is windstorm/hurricane certified, which is the combination institutional and healthcare specs usually call for.
5) Do I have to use Corbin Russwin cylinders in this mortise lock, or will my existing keyway work?
It runs on new or existing Corbin Russwin key systems and accepts most other manufacturers' cylinders, so a building already keyed to another brand can usually be maintained without rekeying the whole site. The standard Corbin Russwin cylinder is brass, 6-pin, L4 keyway, 0-bitted so a locksmith pins it to your system. Note that the lockbody itself ships non-keyed, with the cylinder ordered separately.
6) Will the ML2024 fit the mortise pocket already cut in my door?
The lock case is heavy-gauge steel at 5-7/8 x 4 x 15/16 inches, with a wrought brass, bronze or stainless armored front measuring 8 x 1-1/4 inches. On the trim side, center to center from knob or lever to cylinder is 3-5/8 inches (92mm) and knob or lever to thumbturn is 2-7/16 inches (62mm). Compare those numbers to the existing pocket and face prep before you order; a standard ANSI mortise prep with a 2-3/4 inch backset takes it directly.
7) What is a cross-brand equivalent to the Corbin Russwin ML2024 mortise lock body?
The Accentra 8800FL Series mortise lock body is the closest cross-brand peer. Both are ANSI/BHMA Grade 1 mortise lock bodies, and both are field reversible for handing, so either can be set to the swing of the opening after it reaches the site. The ML2024 is the entrance/storeroom function body in the ML2000 Series, prepared for a 1-3/4 inch door with a 2-3/4 inch backset and shipped with an ANSI straight lip strike measuring 4-7/8 by 1-1/4 inches with a 1-1/8 inch lip to center. Confirm the function code and strike prep on the Accentra body match what the opening already has before treating the two as drop-in for each other.
8) Does a Grade 1 mortise lock body from another manufacturer fit the same door prep as the ML2024?
Grade 1 alone does not settle it. ANSI/BHMA Grade 1 is a performance rating covering cycle and strength testing, and both the Corbin Russwin ML2024 and the Accentra 8800FL Series body carry it, but the rating says nothing about case dimensions, spindle and cylinder hole spacing, or armored front size. The ML2024 uses a heavy-gauge steel case measuring 5-7/8 by 4 by 15/16 inches, an 8 by 1-1/4 inch armored front, and 3-5/8 inch center-to-center spacing from lever to cylinder. Compare those figures against the body you are replacing; if the pocket and cross-bores were cut for a different case, the swap needs door work regardless of grade.
9) Is a Grade 1 mortise lock worth it over a cylindrical lock for a high traffic entry?
For a door that sees constant use, the mortise body carries the load in a steel case set into the door edge rather than through a bored hole, and this one is ANSI/BHMA A156.13 Series 1000, Operational and Security Grade 1, cycle tested to 14.5 million cycles. It also puts the deadbolt in the same case, so one prep does entry security and egress. The trade off is the door has to be mortise prepped; a cylindrical lock is the simpler retrofit on a door already bored for one.
10) Can this lock be set up for other functions later, or am I locked into entrance/storeroom?
The ML2024 is ordered as the F21 entrance/storeroom function. Within the ML2000 family, the ML2054 lockbody is the multi-function body, configurable to 12 different functions from one case, which is what facilities buyers standardize on when they want one part number covering office, classroom and storeroom doors. If the electrified path matters, Motorized Electric Latch Retraction is offered on the ML20900 series.
11) What else could I use instead of the Corbin Russwin ML2024 if I need a field reversible Grade 1 mortise body?
The Accentra 8800FL Series Grade 1 mortise lock body is the closest cross-brand equivalent we carry, also Grade 1 and also field reversible in handing. The practical decision is usually keying: if the building is already on a Corbin Russwin key system, staying with the ML2000 body keeps the cylinders and the master key schedule intact, and it accepts most other manufacturers' cylinders besides.
12) Does the ML2024 close easily on a door with a closer, or does the latch drag?
The latchbolt is a two-piece mechanical design with an anti-friction insert, 5/8 x 1 inch with a 3/4 inch throw, which cuts the force needed to close the door. That matters on doors with a heavy closer or where an ADA-compliant opening force is being held. The auxiliary latchbolt deadlocks the main latch at 9/16 inch effective throw so the latch cannot be loided once the door is shut.
13) I need a mortise lock for an opening that swings the other way. Do I have to order a different part number?
No. The Corbin Russwin ML2024 mortise body is field reversible, and its patented Quick Reversible latchbolt is re-handed without opening the lock case, so one part number covers both hands of an opening. The Accentra 8800FL Series mortise lock body is also field reversible in handing. For a property manager or contractor stocking spares across a building, either approach means a single body on the shelf rather than a left-hand and right-hand pair.
14) What looks like a substitute for the ML2024 but is not?
A complete mortise lockset is not the same order. The Corbin Russwin ML2024 is a mortise lockbody only, non-keyed as supplied, so it carries no lever trim and no cylinder in the box; you are buying the case that goes in the door pocket. The Accentra 8800FL Series item is likewise a mortise lock body rather than a full lockset. If the door has no usable trim or cylinder on it now, a body-only part from either brand leaves the opening incomplete, and the trim, cylinder, and any thumbturn have to be sourced alongside it.
15) What finishes does the Corbin Russwin ML2024 mortise lockbody come in?
Fourteen finishes, covering the full BHMA range: 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 matching existing openings in a commercial building, 626 and 630 are the two you will most often be replacing.
16) Is there a vandal resistant version of the ML2000 mortise lock for a high risk door?
Yes, the ML2000VR configuration. It uses vandal-resistant stainless steel escutcheons with tapered edges and Torx pin tamper-resistant screws, and it pairs with Corbin Russwin patented high-security Pyramid or Access 3 cylinders. Trim across the family is thru-bolted, which holds alignment and makes the trim harder to pull. Worth specifying on public restrooms, transit and detention-adjacent openings.
17) Can staff tell at a glance whether a room locked with the ML2000 mortise lock is secured?
Status indicator options are offered on the ML2000 Series showing locked or unlocked, available with sectional and escutcheon trim. That is specified with the trim, not the lockbody, so call it out when you order the trim design. Trim choices across the series include Museo, Vineyard and the Behavioral Health BHSS and BLSS lines for healthcare openings.
