Corbin Russwin ML2022-LWA-626 – Frequently Asked Questions

1) What does the Store Door function on the Corbin Russwin ML2022 mortise lock actually do?
Store Door is ANSI function F09, a double cylinder setup with a deadbolt. Both levers are always free to retract the latchbolt, and the 1 inch stainless steel deadbolt is thrown or retracted by key from either side. That is the standard arrangement for a retail or tenant entrance where staff want free passage during business hours and a keyed deadbolt at close. If you need the outside lever to stay locked at all times with key entry only, storeroom function is the one to ask for instead.
2) Will the ML2022 mortise lock fit a 1-3/4 inch commercial door with a 2-3/4 inch backset prep?
Yes. The ML2022 is built for 1-3/4 inch (44mm) door thickness with 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. Center to center, lever to cylinder is 3-5/8 inches and lever to thumbturn is 2-7/16 inches. Optional door thicknesses are available if your door is heavier than 1-3/4 inches.
3) Do I have to order the ML2022 mortise lock handed, or can it be reversed in the field?
Order it and reverse it on site if the opening turns out opposite to what the drawing said. The ML2022 uses a patented Quick Reversible latchbolt, so handing changes without opening the lock case. That is a real time saver for a property manager carrying one spare for several openings.
4) Will this Corbin Russwin mortise lock latch into the strike already in my frame?
The latchbolt is a two-piece anti-friction design with a 3/4 inch (19mm) throw and there is a deadlocking auxiliary latch with 9/16 inch effective throw, plus the 1 inch deadbolt throw. The strike supplied is the ANSI straight lip type, 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center. If your frame already has an ANSI strike of that size with a deadbolt pocket above the latch, it lines up. A frame prepped for a cylindrical lock with a small T-strike will not work and needs to be prepped for the ANSI strike.
5) Can I key this Corbin Russwin ML2022 into my existing master key system?
It works with new or existing Corbin Russwin key systems, and the lock body also accepts most other manufacturers' cylinders if your building is keyed to another brand. The cylinder supplied is brass, six pin, L4 keyway, shipped 0-bitted so your locksmith can pin it to the system. Corbin Russwin publishes a Key Systems Catalog covering the keyway options.
6) Is this mortise lock approved for a fire rated opening?
Yes. The ML2022 is UL/cUL listed to UL10C positive pressure and carries a 3-hour fire door rating up to 4 ft x 10 ft single or 8 ft x 10 ft pair. It is also listed to ANSI/BHMA A156.13 Series 1000, Operational and Security Grade 1, meets ADA A117.1, and holds California State Fire Marshal and windstorm/hurricane certification. Note that on a fire door a deadbolt function has to be coordinated with your local code official for egress.
7) Is the Sargent 4874 a substitute for the Corbin Russwin ML2022?
They are not interchangeable. The Sargent 4874 from the 4870 Series is a double cylinder mortise deadbolt on a 2-3/4 inch backset - deadbolt only, with no latchbolt or lever trim. The ML2022 is a store door function mortise lock that combines a latchbolt with LW-Lustra lever trim and a deadbolt in one 5-7/8 in. x 4 in. x 15/16 in. case. Use the 4874 only where a separate deadbolt above an existing latch is wanted.
8) How durable is the ML2000 Series lock for a high traffic entrance?
The lockcase is heavy-gauge steel and the ML2000 Series completed UL cycle testing at 14.5 million cycles (Verification ID V875753), well past the Grade 1 minimum. The anti-friction two-piece latchbolt takes less force to close, which matters on a door with a closer that gets hit a few hundred times a day. Substrate on the trim is brass or bronze.
9) What lever, rose and finish does this Corbin Russwin mortise lock come with?
It ships with the LW Lustra wrought lever on an A Rose, 2-1/4 inch diameter, in 626 Satin Chrome. The trim is thru-bolted for alignment and pull-off resistance. The ML2000 Series also offers other trim families including Museo, Vineyard, and Behavioral Health (BHSS/BLSS) if you are matching something else in the building.
10) Should I use a mortise lock like this or a cylindrical lock on a store entrance?
A mortise lock pockets into the door edge and carries both a latchbolt and a separate 1 inch deadbolt in one case, so you get keyed deadbolting and free egress hardware in a single prep. A cylindrical lock like the Schlage PC10 passage bores through the face of the door and has no deadbolt. For a retail or tenant entrance that gets locked down at night, the mortise route is the one that gives you the deadbolt without adding a second lock to the door.
11) What is the difference between this Store Door lock and a storeroom mortise lock?
Store Door (F09) keeps both levers free and secures the door with a key-operated deadbolt from either side. A storeroom function keeps the outside lever locked permanently, entry by key only, with no deadbolt in the scheme. If storeroom is what your spec calls for, the Accentra 8805FL Grade 1 with Arcadia lever and the Cal-Royal NM8080 Grade 1 with interchangeable core option are both storeroom mortise locksets. The Cal-Royal NM8080 is listed for 1-3/4 inch doors like this one.
12) I need a mortise lock with a deadbolt but for a classroom or a bed/bath door instead. What else is there?
Function drives that choice. For privacy with a deadbolt, the Cal-Royal NM8440 is a Grade 1 privacy/bed/bath mortise lockset with deadbolt for 1-3/4 inch doors. For a classroom opening, the Cal-Royal NM8070 is Grade 1 classroom function, also 1-3/4 inch. If you want a deadbolt only with no lever set, the Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset, which matches the backset used here.
13) I need the ML2022 function but with electric latch retraction tied to access control - what are my options?
The ML2022 itself is a mechanical lock. For an electrified mortise on the same prep, the Command Access ML190 Series motorized mortise lock is a heavy-duty storeroom function unit with field selectable EL/EU operation on 24VDC, the BEST 45HW is a heavy duty wired electromechanical mortise lock with 12V/24V operation, and the Schlage L9092EU 03A provides electric lock/unlock of the outside lever, keyed outside, with request to exit on 12/24VDC for 1-3/4 inch doors.
14) I need a keyed entry mortise lock but not the double cylinder deadbolt of the ML2022 - what else works?
The ML2022 pairs a store door function with a 1 inch stainless steel deadbolt. For a keyed entry or office opening without that deadbolt, the Cal-Royal NM8050 is a Grade 1 office/entrance mortise lockset with an auxiliary deadlatch for 1-3/4 inch doors. The Hager 3850E from the 3800 Series is a Grade 1 office mortise lock with lever and escutcheon on a 2-3/4 inch backset, non-keyed, for doors 1-3/4 in. to 2-1/2 in. thick.
15) What keypad or credential mortise lock can replace the ML2022 if I want to stop issuing keys?
The ML2022 is a mechanical, non-electronic lock with a 6-pin L4 keyway cylinder. For credential-based access on a mortise prep, the Dormakaba E-Plex E5086 is a Grade 1 electronic pushbutton and card mortise lock in an entry/egress back-to-back configuration, and the Schlage LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125 kHz proximity reader and mobile-enabled deadbolt, rated 3 hours, in Greenwich trim, right hand.
16) What is the difference between the ML2022 and a BEST 45H mortise lock body?
The Corbin Russwin ML2022 ships as a complete Grade 1 store door lock with LW-Lustra lever, A rose and a 6-pin L4 keyway cylinder. The BEST 45HCAC is a heavy duty mortise lock body in public entrance function with field reversible operation, and the BEST 45HCAINL is a heavy duty lockbody in intruder function - lock bodies, so trim and cylinder are specified separately. Both the ML2022 and the 45HCAC are field reversible for handing.
17) Which mortise lock replaces the ML2022 on a behavioral health door that needs anti-ligature trim?
The ML2022 uses LW-Lustra lever trim on an A rose. Where ligature resistance governs, the TownSteel MRX-L-01 is a Grade 1 heavy duty stainless steel anti-ligature lever mortise lockset in passage function for 1-3/4 inch doors, the MRX-A-01 is the same passage function with satin stainless ligature resistant arch trim, and 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. All three are passage function rather than keyed.
18) Is the Schlage PM010 an alternative to the Corbin Russwin ML2022?
Only for an unkeyed opening. The Schlage PM010 from the PM Series is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, with no cylinder and no deadbolt. The ML2022 is a keyed store door function with a 1 inch throw stainless steel deadbolt. The Falcon MA101 is another Grade 1 heavy duty mortise passage lock with field reversible operation if passage is what the door calls for.
19) Will a Marks USA 21AC or 22AC work in place of the ML2022 on a storefront door?
Not on a standard 1-3/4 inch commercial door. The Marks USA 21AC and 22AC are entrance double cylinder ornamental iron mortise locks with round knob, listed for 1 inch door thickness - narrow ornamental iron stiles. The Corbin Russwin ML2022 is built for 1-3/4 in. (44mm) doors with a 5-7/8 in. x 4 in. x 15/16 in. steel case.
20) For a dormitory or corridor door, is the ML2022 the right function or is there a better mortise lock?
The ML2022 is a store door function, where both levers are controlled together at the cylinder. For a dorm or corridor opening that needs an exit function with a deadbolt, the Sargent 7925 from the 7900 Series is a heavy duty Grade 1 dormitory exit function mortise lock with rose trim and a single cylinder deadbolt.
21) If I standardize on the ML2000 lock body, can I change functions later without buying a new lock?
Within the series, twelve functions are configurable from a single ML2054 lockbody. For a facility that stocks spares, that means one body on the shelf can be set up for several different openings rather than carrying a separate part number for each function. Status indicator options for locked/unlocked visibility are available on sectional and escutcheon trim.
