Corbin Russwin ML20914-RWA-626-SAF – Frequently Asked Questions

1) What is the difference between the fail safe and fail secure versions of the Corbin Russwin ML20914?
Both are orderable on the ML20914. Fail safe means the lever unlocks when power is removed, so the opening is free on a power loss or alarm; fail secure means the lever stays locked when power drops and a key or valid credential is still needed. Pick fail safe where egress or firefighter access on power failure matters, fail secure where the opening must stay secure through an outage. The choice is built into the lock, so specify it on the order.
2) Will the ML20914 mortise lockset fit a 1-3/4 inch commercial door?
Yes. 1-3/4 inches (44mm) is the standard door thickness for the ML20914, and the range runs 1-3/8 inches up to 4 inches with optional thicknesses. Backset is 2-3/4 inches standard, with 2-3/8 to 2-3/4 inch backsets available, so it drops into a standard ANSI mortise pocket.
3) Do I have to order the ML20914 handed, or can it be reversed in the field?
It ships handed but the latchbolt is patented Quick Reversible, so handing is changed in the field without taking the lock case apart. That is useful for a property manager holding stock for a mixed building, since one lock covers both hands of opening.
4) Can I use the ML20914 on a 3-hour fire rated door?
Yes. The ML20914 is UL and cUL listed and UL10C positive pressure compliant for fire doors rated up to and including 3 hours, covering single doors up to 4 ft x 10 ft and pairs up to 8 ft x 10 ft. It also carries ADA A117.1, California State Fire Marshal, and windstorm/hurricane certification for ASTM E330 and Florida Building Code work.
5) Will the ML20914 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 the lock is supplied with an ANSI straight lip strike, 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center. If your frame already has a standard ANSI 4-7/8 inch mortise strike prep with matching lip-to-center, the existing strike works. The single-cylinder version also carries a one-piece stainless deadbolt with a 1 inch throw, plus a 9/16 inch deadlocking auxiliary latch.
6) Can I key the ML20914 into my existing Corbin Russwin master key system, or order it without a cylinder?
Both work. The lock accepts new or existing Corbin Russwin key systems and will take most other manufacturers' cylinders. Order it with the L4 keyway (brass 6-pin cylinder, 0-bitted as standard so your locksmith can pin it) or specify Less Cylinder if you are supplying your own core from house stock.
7) What do I need to specify when ordering the ML20914 electrified mortise lock?
Four things beyond the model. Function (fail safe or fail secure), finish (626 satin chrome or 630 satin stainless steel), keying (L4 keyway or less cylinder), and the trim style: an A rose or an M, N, or R escutcheon, all with the RW Regis wrought lever. You also choose whether to include request-to-exit (RX) monitoring, which reports lever operation back to the access control panel.
8) Will the mortise pocket in my door take this lock case?
The ML20914 uses a heavy-gauge steel lock case measuring 5-7/8 x 4 x 15/16 inches (149 x 102 x 24mm) with an 8 x 1-1/4 inch armored front. That is the standard ANSI mortise footprint, so an existing ANSI mortise prep takes it. Trim spacing is 3-5/8 inches (92mm) center to center from lever to cylinder and 2-7/16 inches (62mm) lever to thumbturn, which is what to check against existing through-holes on a retrofit.
9) What is the closest cross-brand equivalent to the Corbin Russwin ML20914-RW electrified mortise lockset?
The closest peer is the Schlage L9092EU electrified mortise lock with 03A trim, which is a heavy duty mortise lock for 1-3/4 inch doors with an electrically controlled outside lever, keyed outside, request-to-exit monitoring, and 12/24VDC operation. The ML20914-RW is likewise a Grade 1 mortise electrified lever lockset for a 1-3/4 inch door with a 2-3/4 inch backset, offered in Fail Safe and Fail Secure builds and with or without request-to-exit monitoring. Another electrified mortise option is the BEST 45HW wired electromechanical mortise lock, a heavy duty lock with 12V/24V operation.
10) If the opening does not need electrification, what mortise lock should be used instead of the ML20914-RW?
For a mechanical opening, pick a keyed mortise lockset in the function the door needs rather than an electrified body. The Accentra 8805FL is a Grade 1 storeroom mortise lock with an Arcadia lever, the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option for a 1-3/4 inch door, the Cal-Royal NM8070 is the Grade 1 classroom version, and the Cal-Royal NM8050 is the Grade 1 office/entrance version with auxiliary deadlatch. The ML20914-RW is built for access-controlled openings with Fail Safe and Fail Secure operation.
11) Can a standalone electronic mortise lock replace the ML20914-RW?
Only if the opening does not need to be wired into an access control system. Standalone electronic mortise locks such as the Alarm Lock DL3500CR Trilogy, a Grade 1 classroom-function keypad lock for 1-5/8 to 1-7/8 inch doors, the Schlage CO-100 standalone electronic mortise lock with keypad reader in privacy function, and the BEST 45HZ EZ Series electronic keypad mortise lock with key override manage credentials at the door. The ML20914-RW is an electrified lockset whose latch is driven by applied power in Fail Safe or Fail Secure mode, so it depends on a power supply and upstream control.
12) Which mortise products look like alternatives to the ML20914-RW but will not secure the opening?
Several mortise-family items are trim or non-keyed bodies and cannot take the place of a keyed electrified lockset. The Schlage L0170 is half dummy trim, a Grade 1 non-keyed lever for 1-3/4 inch doors, and the Falcon MESC600DT is dummy escutcheon lever trim for M9900 Series exit devices. The Schlage PM010 and Falcon MA101 are passage mortise locks, non-keyed and latch-only. The Sargent 130KB and 130W are mortise thumbturns. The ML20914-RW is a single cylinder keyed electrified lever lockset ordered with an L4 keyway cylinder or less cylinder.
13) Can the ML20914-RW be used on a 1-1/2 inch aluminum stile door or a glass entrance?
No. The ML20914-RW is specified for a 1-3/4 inch door with a 2-3/4 inch backset and a lockcase 5-7/8 inches by 4 inches by 15/16 inch. For narrow stile and glass openings, look at the Dormakaba E-Plex E2066 wide stile electronic pushbutton mortise lock, the Alarm Lock DL1300NW Trilogy Networx wireless mortise lock made for Adams Rite deadlatches, or the Kaba Ilco BR Series glass door bottom rail lock.
14) What should be used instead of the ML20914-RW on a door with no available wiring or power supply?
Where power cannot be run, consider a self-powered or battery electronic mortise lock. The Dormakaba PowerPlex P2066 Series mortise lock is one option, and the Dormakaba E-Plex E5086 is a Grade 1 entry/egress electronic pushbutton and card mortise lock in a back-to-back configuration. The ML20914-RW relies on applied power for its Motorized Electric Latch Retraction, which retracts the latchbolt in one half second.
15) Do I need request-to-exit monitoring on an electrified mortise lock?
Only if your access control system has to know when someone left from the inside. RX monitoring is an option on the ML20914 and sends a signal when the inside lever is turned, which is what lets the panel shunt a door alarm on legitimate egress instead of logging a forced door. If the lock is just being unlocked by a card reader with no alarm monitoring on the opening, you can skip it.
16) Is a Grade 1 electrified mortise lock durable enough for a high-traffic entrance?
It meets ANSI/BHMA A156.13 Series 1000 at Operational and Security Grade 1, the top commercial rating for mortise locks, and has been UL cycle tested to 14.5 million cycles (verification ID V875753). The anti-friction two-piece latchbolt also reduces closing force, which helps on a door with a closer on a busy corridor.
17) I don't want to run power to the door. What mortise lock should I use instead?
An electrified lock like the ML20914 needs a power supply and wire transfer to the door. If you would rather avoid that, standalone keypad and credential mortise locks cover the same openings: the Alarm Lock DL3500CR is a Grade 1 classroom-function electronic mortise lock with 300 user codes, the Schlage CO-100 is a Grade 1 standalone keypad mortise lock, and the TownSteel FME-2000 is a Grade 1 classroom mortise lockset with RFID. For a purely mechanical keyed opening, the Cal-Royal NM8080 storeroom lockset is Grade 1 for 1-3/4 inch doors.
18) Can one ML2000 lock body cover several different lock functions across a building?
Yes. The ML2054 lock body is multi-function and can be configured for 12 different functions, so a facility can stock one body and set it for office, storeroom, classroom or similar as needed rather than carrying a separate lock for each opening. Trim is thru-bolted for alignment, and status indicator options are available on sectional and escutcheon trims where staff need to see locked or unlocked at a glance.
19) What is the difference between the ML20914-RW and a wireless mortise lock like the Schlage LEMD-GRW?
The Schlage LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader, mobile-enabled deadbolt with LED, Greenwich trim, right hand, and a 3-hour fire rating; credentials are read at the door and communicated wirelessly. The ML20914-RW is a hardwired Grade 1 electrified mortise lever lockset, field reversible for handing, ordered in Fail Safe or Fail Secure with optional request-to-exit monitoring. TownSteel also offers RFID mortise locksets, the FME-2000 Series in Grade 1 classroom function and the FME-4000 Series electronic intruder classroom version, both for 1-3/4 inch doors.
20) Is the Command Access ML190 a substitute for the Corbin Russwin ML20914?
They are close in concept. The Command Access ML190 Series is a heavy-duty motorized mortise lock in storeroom function with field selectable EL/EU operation on 24VDC, meaning the electric latch behavior is set at install. The ML20914-RW instead ships as a specific Fail Safe or Fail Secure build, uses Motorized Electric Latch Retraction, and is ordered with the RW Regis wrought lever in an A rose or M, N, or R escutcheon.
21) Will a behavioral health or anti-ligature mortise lockset work where the ML20914-RW is specified?
For ligature-resistant openings, TownSteel offers the MRX-L-01, a Grade 1 heavy duty stainless steel anti-ligature lever mortise lockset in passage function for 1-3/4 inch doors, and the MRX-A-01 with satin stainless ligature resistant arch trim. Marks USA offers the 5PDN, a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant in satin stainless steel. Those are passage function, so they do not lock; the ML20914-RW is a keyed electrified lockset available in a 630 satin stainless steel finish.
22) What are the alternatives if the opening needs a mortise deadbolt rather than an electrified lever lockset?
For deadbolt-only openings, the Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset, matching the ML20914-RW backset, and the Kaba Ilco 185 Series is a no-handing mortise deadbolt. If keypad control of a deadbolt is wanted, the Alarm Lock DL4500 Series is a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad for 1-5/8 to 1-7/8 inch doors. The ML20914-RW is a single cylinder both-grips-lock lever set with a 1 inch stainless steel deadbolt in the lockbody.
23) How does the ML20914-RW compare with a Grade 2 electronic mortise lock such as the Schlage LEBMB-ADD?
The Schlage LEBMB-ADD is a BHMA Grade 2 mobile-enabled mortise lock with push button and LED, covering privacy, office, and apartment functions on a 1-3/4 inch door with a 3-hour fire rating. The Dormakaba Saffire LX-I-M002 RFID mortise lockset with BLE mobile access is also BHMA Grade 2. The ML20914-RW is built to ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1 and is UL-cUL listed for fire doors rated up to and including 3 hours.
24) Which mortise lock bodies are field reversible like the ML20914-RW?
The ML20914-RW is field reversible and uses a patented quick reversible latchbolt that can be re-handed without disassembling the lock case. Among peers, the BEST 45H Series heavy duty mortise lock body in public entrance function is field reversible, and the Falcon MA101 Grade 1 heavy-duty mortise passage lock also offers field reversible operation. Note that the Schlage LEMD-GRW wireless mortise lock is listed specifically as right hand.
25) Does the ML20914 come in a finish that matches stainless steel hardware on my other doors?
Two finishes are offered: 626 satin chrome and 630 satin stainless steel. 630 is the usual match for satin stainless push plates, hinges and exit devices; 626 satin chrome is the common match for existing brass-substrate satin chrome trim. The armored front and strike are supplied in wrought brass, bronze, or stainless steel depending on finish.
