Corbin Russwin ML20906-RWA-626-SAF – Frequently Asked Questions

1) Does the Corbin Russwin ML20906 mortise lockset fit a 1-3/4 inch commercial door?
Yes. The ML20906 is set up for 1-3/4 inch (44mm) doors as standard, and the ML2000 lock case accommodates thicknesses from 1-3/8 inch up to 4 inch with the optional thickness kits. Backset is 2-3/4 inches, the standard commercial mortise backset, so the pocket prep on an existing ANSI mortise opening carries straight over.
2) What is the difference between ordering the ML20906 fail safe versus fail secure?
Both are orderable on the ML20906 and you pick one at the order form. Fail safe unlocks the outside lever when power drops, which is what you use on stair re-entry and egress paths that must free up in an alarm. Fail secure keeps the outside lever locked with power off, which is the normal choice for a storeroom, server room, or any opening that must stay secured during an outage. Key override on the outside cylinder works either way.
3) Will the ML20906 latch into my existing ANSI mortise strike?
It should. The ML20906 uses a 3/4 inch (19mm) throw two-piece anti-friction latchbolt with a deadlocking auxiliary latch at 9/16 inch effective throw, and it ships with an ANSI straight lip strike, 4-7/8 x 1-1/4 inch with 1-1/8 inch lip to center. If the frame already has a standard ANSI 4-7/8 strike cutout, the throw and lip-to-center match up. Measure your existing lip to center before reusing the old strike; a longer lip is what you need on a frame with deeper stop.
4) Do I have to specify handing when I order the ML20906?
The lock is handed as shipped but it is field reversible. Corbin Russwin's quick reversible latchbolt lets you flip the hand without opening the lock case, so a wrong-hand delivery is not a return. Trim orientation still needs to match the opening, so give the hand on the order anyway if you know it.
5) What keying options can I get on the Corbin Russwin ML20906, and can I key it to my existing system?
Four keying choices: a conventional 6-pin cylinder in the L4 keyway, an IC 6-pin housing less core, L4 keyway, or less cylinder if you are supplying your own. Conventional cylinders ship 0-bitted brass so a locksmith can pin them to your existing Corbin Russwin system, including the patented Access 3 and Pyramid high security systems. The lock also accepts most other manufacturers' cylinders, so it can be brought into a non-Corbin masterkey system.
6) Can the ML20906 be used on a 3-hour fire rated door?
Yes. The lockset is UL and cUL listed and carries UL10C positive pressure compliance for 3-hour fire doors up to 4 ft x 10 ft single or 8 ft x 10 ft pair. It is also certified 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. On a fail safe opening, check with your AHJ, since fire doors generally have to stay latched.
7) Will the ML20906 fit the mortise pocket already cut in my door?
The lock case measures 5-7/8 x 4 x 15/16 inches (149 x 102 x 24mm) in heavy-gauge steel, with an 8 x 1-1/4 inch armored front. Center to center from lever to cylinder is 3-5/8 inches (92mm), and lever to thumbturn is 2-7/16 inches (62mm). Compare those three numbers against the existing prep: the case depth and face dimensions decide whether the pocket takes it, and the cylinder centerline decides whether the existing through-holes line up.
8) I have a Baldwin or Marks mortise lock in the door now. Can I drop the ML20906 straight in?
Probably not without reworking the prep. The ML20906 is a 2-3/4 inch backset ANSI mortise lock. Baldwin 6301 and 6310 mortise bodies are 2-1/2 inch backset, and the Marks USA 21AC and 22AC ornamental iron locks are built for 1 inch thick doors. Different backset means the cylinder and lever holes land in different places, and a 1 inch door will not take this case at all. Swap like for like on backset and door thickness, or plan on a new door.
9) What is the closest electrified mortise lock to the Corbin Russwin ML20906 from another manufacturer?
The Schlage L9092EU with 03A trim is the nearest cross-brand equivalent. Both are heavy duty electrified mortise locks fitted to 1-3/4 inch doors, both are keyed on the outside, and both can be supplied with request to exit monitoring - the Schlage is catalogued with RX and 12/24VDC operation, and the ML20906 is ordered with request to exit monitoring as a yes/no option. The differences are in the electric behavior and the keying: the Schlage L9092EU is an electric lock/unlock outside lever in a corridor function, while the ML20906 is offered in Fail Safe and Fail Secure builds with Motorized Electric Latch Retraction and a 6-pin L4 keyway, 2-3/4 inch backset, and a 3/4 inch latchbolt.
10) Is there a motorized electrified mortise lock I can use instead of the Corbin Russwin ML20906?
The Command Access ML190 is the other motorized option. It is a heavy-duty motorized mortise lock in a storeroom function with field selectable EL/EU operation and 24VDC power, so the fail safe or fail secure decision is made at the lock during install rather than at the time of order. The Corbin Russwin ML20906 is ordered as a specific Fail Safe or Fail Secure build from the ML2000 Series with Motorized Electric Latch Retraction, and it is offered with a Regis wrought lever in 626 satin chrome or 630 satin stainless steel.
11) If the opening has no power or access control wiring, what mortise lock should I use instead of the ML20906?
Use a mechanical Grade 1 mortise lockset - the ML20906 is a Fail Safe/Fail Secure electrified lock and expects an access control circuit. For an unwired opening the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option. If the opening needs classroom function instead of storeroom, the Cal-Royal NM8070 is the Grade 1 classroom version for 1-3/4 inch doors.
12) We want credentials at the door rather than a wired access control panel - what replaces the ML20906?
A standalone or wireless electronic mortise lock does that job. The Schlage LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and mobile-enabled operation, 3 hour fire rated. The TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID technology for 1-3/4 inch doors. The Dormakaba E-Plex E5086 is a Grade 1 pushbutton and card entry/egress mortise lock. The Corbin Russwin ML20906 carries no reader of its own - it is a keyed Fail Safe/Fail Secure lock with motorized latch retraction that takes its release signal from a separate access control system.
13) Does the ML20906 include request to exit monitoring, or is that a separate option?
Request to exit is a build option, ordered yes or no. With RX, the lock signals the access control panel when the inside lever is turned, so egress does not fire the door-forced alarm. If you are tying into an existing panel that expects an REX input, specify it up front. It is not something you add to the lock afterward in the field.
14) What is MELR on the ML20900 series and when do I need it?
MELR is Motorized Electric Latch Retraction, available on the ML20900 series. It pulls the latchbolt back electrically so the door pushes open freely under an access control signal, which is what you want on an opening tied to a card reader, push plate, or automatic operator. If you only need the outside lever to unlock and the user still turns the lever, standard electrified operation is enough and you do not need latch retraction.
15) What trim and finish combinations does the ML20906 come in with the RW Regis lever?
With the RW Regis (Wrought) lever, you choose an A rose or one of three escutcheon styles, M, N or R, in either 626 satin chrome or 630 satin stainless steel. Escutcheon trim covers more of the door face, which is useful when you are replacing an older lock and the existing prep or filled holes would show around a rose. All trim is thru-bolted.
16) What is the alternative to the ML20906 if I want a standalone keypad or card lock instead of wiring to an access control panel?
The ML20906 is a wired electrified lock and assumes a panel, power supply, and transfer hinge or power transfer at the opening. If you want no wiring, ZenSupply carries standalone mortise locks such as the Alarm Lock DL3500CR Trilogy, a Grade 1 classroom-function electronic mortise lock with 300 user codes, and the Dormakaba E-Plex 2066 pushbutton keyless mortise lock. For credential-based standalone, the TownSteel FME-2000 Series is a Grade 1 classroom mortise lockset with RFID. None of those give you latch retraction or central fail safe control, which is the tradeoff.
17) Is the ML20906 durable enough for a high-traffic entrance in an apartment building or school?
It is built for that. The lockset is certified to ANSI/BHMA A156.13 Series 1000, Operational and Security Grade 1, which is the top commercial grade, and the UL cycle verification runs to 14.5 million cycles. The case is heavy-gauge steel with a one-piece stainless deadbolt at 1 inch throw and thru-bolted trim, which is the part that keeps levers from working loose on a door that gets hit a few hundred times a day.
18) If I do not need an electrified lock, what mechanical Corbin Russwin or other Grade 1 mortise lock should I look at instead?
Drop the electrification and you are picking a plain function instead. From what ZenSupply stocks in Grade 1 mechanical mortise: Accentra 8805FL for storeroom, Cal-Royal NM8080 for storeroom with an interchangeable core option, NM8070 for classroom, NM8050 for office/entrance, and NM8440 for privacy with deadbolt, all on 1-3/4 inch doors. Falcon MA101 covers passage. Going mechanical also drops the power supply, transfer device, and panel wiring from the job.
19) How does the BEST 45HW wired mortise lock compare with the Corbin Russwin ML20906?
Both are wired electromechanical heavy duty mortise locks intended to run off an access control circuit. The BEST 45HW is specified as 12V/24V operation in the 45HW Wired Mortise Series. The ML20906 is an ANSI/BHMA Grade 1 ML2000 Series lock offered in Fail Safe and Fail Secure builds with Motorized Electric Latch Retraction, a 2-3/4 inch backset, an ANSI straight lip strike with 1-1/8 inch lip to center, and keying choices that include a 6-pin L4 cylinder, IC 6-pin less core, or less cylinder.
20) Will a BEST 45H mortise lock body work as a replacement for the ML20906?
No. The BEST 45H is a mechanical mortise lock body - the 45HCAC is a heavy duty public entrance function and the 45HCAINL is an intruder function lockbody - and neither carries electrification. The Corbin Russwin ML20906 is a Fail Safe/Fail Secure electrified lockset with motorized latch retraction and optional request to exit monitoring, so swapping in a 45H lockbody gives up the access control release entirely. Both the 45H bodies and the ML20906 are field reversible for handing.
21) For a classroom door that needs lockdown but not a wired access control tie-in, what should I specify instead of the ML20906?
Look at a standalone keypad or intruder-function classroom lock. The Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with 300 user codes in a classroom function for doors 1-5/8 to 1-7/8 inch, and the DL2700CR is the Trilogy T2 classroom version with a weatherproof design over the same thickness range. The TownSteel FME-4000 is an electronic intruder classroom mortise lockset with RFID for 1-3/4 inch doors. The Corbin Russwin ML20906 fits 1-3/4 inch doors and is a Fail Safe/Fail Secure electrified lock that depends on an external access control system for its release.
22) The door only needs latching, no keying or power - is there a simpler mortise lock than the ML20906?
Yes. For a non-keyed opening the Schlage PM010 is a Grade 1 passage latch mortise lock for 1-3/4 inch doors, the Falcon MA101 is a Grade 1 heavy duty fire rated mortise passage lock that is field reversible, and the Hager 3810S and 3810E are Grade 1 passage mortise locks with a 2-3/4 inch backset in rose and escutcheon trim respectively. All of them drop the cylinder and the electrification that the Corbin Russwin ML20906 carries - the ML20906 is a single cylinder Fail Safe/Fail Secure electrified lockset and shares the 2-3/4 inch backset.
23) Is the Sargent 4874 mortise deadbolt an alternative to the ML20906?
No - they do different jobs. The Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset with no latch and no lever, so it secures the door but does not latch it or operate from trim. The Corbin Russwin ML20906 is a single cylinder electrified mortise lockset with a Regis wrought lever, a 3/4 inch latchbolt, and Fail Safe/Fail Secure operation. They share the 2-3/4 inch backset, so a 4874 is a companion deadbolt rather than a replacement lock.
24) For a behavioral health or ligature-resistant opening, what mortise lock should I look at instead of the ML20906 with a Regis lever?
The TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in stainless steel in a passage function for 1-3/4 inch doors, and the MRX-A-01 is the ligature resistant arch trim version in satin stainless steel. The Marks USA 5PDN is a Grade 1 hospital passage push/pull paddleset that is ligature resistant and ADA compliant in satin stainless steel. The Corbin Russwin ML20906 is supplied with the RW Regis wrought lever, which is a conventional lever profile, though the ML2000 Series trim range includes Behavioral Health BHSS and BLSS designs.
25) Can I use the Dormakaba PowerPlex or E-Plex 2066 instead of running power to an ML20906?
They are the no-wiring route. The Dormakaba PowerPlex P2066 is a mortise lock in the PowerPlex 2000 Series, and the E-Plex 2066 is an electronic pushbutton keyless mortise lock for wide stile applications - both put the credential and the power at the door instead of on a panel circuit. The Corbin Russwin ML20906 is the opposite approach: a Fail Safe/Fail Secure electrified mortise lock with Motorized Electric Latch Retraction and optional request to exit monitoring, built to be released and monitored by a central access control system.
26) Are the Baldwin 6301 and 6310 mortise lock bodies interchangeable with the Corbin Russwin ML20906?
No. The Baldwin 6301 entry/apartment and 6310 entry/storeroom mortise lock bodies use a 2-1/2 inch backset, while the ML20906 is a 2-3/4 inch backset lock, so the cylinder and spindle centers do not line up with an ML2000 door prep. The Baldwin bodies are also mechanical, with no electrification, where the ML20906 is a Fail Safe/Fail Secure electrified lockset. The 6301 is offered knob by knob and lever by lever, and the 6310 covers 1-3/8 inch and over door thicknesses.
27) What is the difference between the Sargent 7925 and the Corbin Russwin ML20906 for a dormitory corridor door?
The Sargent 7925 is a Grade 1 heavy duty corridor/dormitory exit function mortise lock from the 7900 Series with rose trim and a single cylinder deadbolt - the deadbolt is thrown at the door by the occupant. The Corbin Russwin ML20906 is a single cylinder ANSI/BHMA Grade 1 electrified mortise lockset with Fail Safe or Fail Secure operation and motorized latch retraction, and it is offered with either rose or escutcheon trim. Choose the 7925 if the room is managed by key alone, and the ML20906 if the corridor side is to be controlled by a card or credential system.
28) Does the Accentra nexTouch NTM623-NR do the same job as the ML20906?
Only partly. The Accentra NTM623-NR is a Grade 1 nexTouch Generation 3 mortise lock with a capacitive touchscreen keypad and cylinder override, no deadbolt - the credential is entered at the lock. The Corbin Russwin ML20906 has no keypad; it is a keyed Fail Safe/Fail Secure electrified lockset with Motorized Electric Latch Retraction that takes its unlock signal from an access control system, and it can be ordered with request to exit monitoring so the system sees egress. Pick the nexTouch for a standalone door and the ML20906 for a door on a head-end system.
29) Will a Schlage L0170 or Falcon MESC600DT work on the inactive leaf of a pair that has an ML20906 on the active leaf?
Those are dummy trims, not locks. The Schlage L0170 is a Grade 1 non-keyed half dummy mortise lever trim for 1-3/4 inch doors, and the Falcon MESC600DT is a dummy escutcheon lever trim, fire rated, made for M9900 Series exit devices. Neither latches or accepts a cylinder. The Corbin Russwin ML20906 on the active leaf is a single cylinder electrified mortise lockset with a 3/4 inch latchbolt - if the inactive leaf needs to latch or lock, it needs its own lockset, not dummy trim.
