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

1) Will the Corbin Russwin ML20906 electrified mortise lock fit a 1-3/4 inch door with a 2-3/4 inch backset prep?
Yes. The ML20906 is built for a 1-3/4 inch door with a 2-3/4 inch 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 an existing ANSI mortise pocket cut for that case. Center to center from lever to cylinder is 3-5/8 inches, lever to thumbturn 2-7/16 inches, which is what decides whether the trim lines up with holes already in the door.
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 means the outside lever unlocks when power drops, which is what you want on a stair re-entry or an egress path tied into fire alarm release. Fail secure keeps the outside lever locked when power drops, so the opening stays secure through an outage and free egress still comes from the inside lever. Get this wrong and the door either stands unlocked in a power failure or traps people behind it, so confirm which the life safety drawing calls for before you order.
3) Can the ML20906 mortise lock be used on a 3 hour fire rated door?
Yes. The ML20906 is UL and cUL listed and UL10C positive pressure rated for fire doors up to and including a 3-hour rating, on a single door up to 4 by 10 feet or a pair up to 8 by 10 feet. It also meets ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1 and ADA A117.1, and carries California State Fire Marshal listing plus windstorm/hurricane certification.
4) Will the ML20906 latch into the strike that is already in my frame?
The lock ships with an ANSI straight lip strike, 4-7/8 x 1-1/4 inches with a 1-1/8 inch lip to center, and throws a 3/4 inch two-piece anti-friction latchbolt plus a 9/16 inch deadlocking auxiliary latch. If your frame already carries an ANSI 4-7/8 inch strike prep, it lines up. If the existing strike is a smaller box or T-strike, plan on replacing it, because 3/4 inch of throw needs the full ANSI pocket depth behind the lip.
5) What keying options come on the Corbin Russwin ML20906 and can I key it to my existing system?
Four keying choices are offered: a 6-pin interchangeable core with the L4 keyway, IC 6-pin less core, standard L4 keyway cylinder, and less cylinder. Standard cylinders are brass 6-pin L4, 0-bitted. It works with new or existing Corbin Russwin key systems, including the patented Access 3 and Pyramid high security systems, and accepts most other manufacturers' cylinders, so a facility already standardized on another brand's cylinder can order it less cylinder and drop in what they stock.
6) Does this Corbin Russwin electrified mortise lock give me a request to exit signal for the access control panel?
Request to exit monitoring is an option you select when ordering, yes or no. Take the RX version when the panel needs to see the inside lever being turned so it can shunt the door contact and avoid a nuisance alarm on legitimate egress. Skip it if the opening is card-in only and the panel already has its own egress device. The lock uses Motorized Electric Latch Retraction and EcoFlex technology, which the manufacturer states cuts energy use on electromechanical functions by up to 89 percent, a real consideration when you are powering a run of doors off one supply.
7) Should I use a wired electrified mortise lock like the ML20906 or a standalone electronic lock?
Wired versus standalone is the first decision, and it turns on whether you are running cable. The ML20906 is a hardwired electrified mortise lock with motorized latch retraction, meant to sit on an access control platform with a power supply and a door position circuit behind it. If there is no head-end and no cable path, a standalone battery lock is the better answer: the Alarm Lock DL3500CR Trilogy is a Grade 1 electronic mortise lock with 300 user codes and classroom function, and the Schlage CO-100 is a Grade 1 keypad mortise lock for privacy openings. If you want wireless credentials reporting back to a system, the Schlage LEMD ENGAGE Series is a Grade 1 wireless mortise lock with a 125kHz proximity reader.
8) What is the closest cross-brand equivalent to a Corbin Russwin ML20906 electrified mortise lock with request-to-exit monitoring?
The Corbin Russwin ML20906 is a mortise electrified lever lockset offered in Fail Safe and Fail Secure builds, with request-to-exit monitoring available as an ordering option. The nearest counterpart from another maker is the Schlage 03A electric lock/unlock outside lever mortise lock, which is keyed outside, includes request to exit (RX), runs on 12/24VDC, is heavy duty, and is a corridor function for 1-3/4 inch doors. Command Access also builds the ML190 series motorized mortise lock with field selectable EL/EU operation on 24VDC in a heavy-duty storeroom function, which covers both the fail safe and fail secure sides from one lockbody the way the ML20906 does across its two function builds.
9) If an opening does not need to be wired back to an access control panel, what mortise lock replaces the ML20906?
The ML20906 is an electrified mortise lockset built for Fail Safe/Fail Secure operation tied into a powered system. Where an opening is controlled at the door rather than from a panel, a mechanical Grade 1 mortise lock covers it: the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option. Both hold the door secured from outside with key access only and need no power run to the frame.
10) What should be used instead of an ML20906 on a door with no power available at the frame but credential access still required?
The ML20906 needs power at the opening for its motorized electric latch retraction. Standalone battery or keypad mortise locks avoid that wiring: the Alarm Lock DL3500CR Trilogy is a Grade 1 electronic mortise lock with 300 user codes in classroom function for 1-5/8 to 1-7/8 inch doors, the BEST 45HZ EZ Series is an electronic keypad mortise lock with key override, and the Dormakaba PowerPlex P2066 is a mortise lock in the PowerPlex 2000 Series. The tradeoff is that credentials are managed at the door rather than through a wired access control head end.
11) Which mortise locks look like alternatives to the ML20906 but will not work on a 1-3/4 inch commercial fire door?
Several mortise locks in the same shape do not fit the same opening. The Marks USA 21AC and 22AC ornamental iron mortise locks are built for 1 inch doors. The Baldwin 6301 and 6310 mortise lock bodies use a 2-1/2 inch backset rather than the 2-3/4 inch backset the Corbin Russwin ML20906 carries, so the existing mortise prep and cylinder spacing will not line up. The Codelocks CL2255 is a medium duty electronic tubular mortise latch, a lighter class of hardware than the Grade 1 ML20906 commercial lockset. The ML20906 is a Grade 1 mortise lock for 1-3/4 inch doors with a 2-3/4 inch backset.
12) For a classroom door being tied into access control, is the ML20906 the right mortise lock or is there a better fit?
The Corbin Russwin ML20906 is an electrified Fail Safe/Fail Secure mortise lockset with request-to-exit monitoring available, which suits a classroom governed centrally from an access control system. Where the room needs to be secured from inside the classroom instead, the TownSteel FME-4000 is a Grade 1 heavy duty electronic intruder classroom mortise lockset with RFID for 1-3/4 inch doors, and the BEST 45HCA lockbody offers an intruder function. For a mechanical classroom function with no electronics, the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with auxiliary deadlatch for 1-3/4 inch doors.
13) Which lock replaces a Corbin Russwin ML20906 on a narrow stile aluminum storefront door?
The Corbin Russwin ML20906 is a mortise lockset with a 2-3/4 inch backset and a 5-7/8 inch by 4 inch by 15/16 inch lockcase, which a narrow aluminum stile will not accept. For storefront and aluminum openings, the Alarm Lock DL1300NW Trilogy Networx is a wireless electronic mortise lock with keypad made for Adams Rite deadlatches, and the Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock in a wide stile configuration. Confirm the stile width and existing deadlatch before ordering either.
14) Do I have to specify handing when I order the Corbin Russwin ML20906?
The lock is handed, but the latchbolt is Quick Reversible, so the hand can be changed in the field without opening up the lock case. For a property manager stocking spares across a building, that means one lock covers both hands of opening rather than carrying two part numbers.
15) What finishes and trim options does the ML20906 with the Newport lever come in?
The Newport cast lever (NS) comes in four finishes: 612 satin bronze, 613 satin bronze oil-rubbed, 626 satin chrome, and 630 satin stainless steel. Trim mounts either as a rose (A or B) or as an escutcheon (M, N, or R). If you are matching openings already in the building, 626 satin chrome and 630 satin stainless are the two that read closest to most existing commercial lever hardware. Trim is thru-bolted for alignment and added security.
16) Do I need an electrified mortise lock, or will a mechanical Grade 1 mortise lock do the job?
Electrify the opening only where a credential reader, an intercom release, or a fire alarm interface has to control the outside lever. Everywhere else on the same project, a mechanical Grade 1 mortise lock is less to install and nothing to power. ZenSupply carries the Cal-Royal NM8080 storeroom and NM8070 classroom Grade 1 mortise locksets for 1-3/4 inch doors, the Accentra 8805FL Grade 1 storeroom from the 8800 Series, and the Sargent 7925 Grade 1 dormitory exit function mortise lock with a single cylinder deadbolt. Those cover the non-access-controlled doors in the same building.
17) Does the Corbin Russwin ML20906 have a deadbolt?
Yes, a one-piece stainless steel deadbolt measuring 19/32 x 1-1/4 inches with a 1 inch throw, alongside the 3/4 inch latchbolt. A 1 inch bolt throw is what most jurisdictions look for on a security opening. Note this is the single cylinder configuration, keyed outside with a thumbturn inside, so it is not the answer where code prohibits a double cylinder or where you need keyed operation from both faces.
18) How durable is the ML20906 for a high traffic entrance that gets thousands of uses a day?
The lock case is heavy-gauge steel and the lock is UL cycle tested to 14.5 million cycles, well past the ANSI/BHMA A156.13 Series 1000 Grade 1 threshold it is certified to. The two-piece anti-friction latchbolt also takes less force to close, which matters on a door with a closer where the latch is being driven home hundreds of times an hour.
19) What mortise hardware suits a behavioral health or ligature-resistant opening rather than the ML20906?
For anti-ligature openings, 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, and the MRX-A-01 is the same passage function with satin stainless ligature resistant arch trim. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant, ADA compliant, and satin stainless steel. The Corbin Russwin ML20906 is a keyed electrified lever lockset with the Newport cast lever, and Corbin Russwin offers Behavioral Health BHSS and BLSS trim within the ML2000 trim range if the opening needs both access control and a behavioral health lever.
20) What is the difference between the Corbin Russwin ML20906 and the BEST 45HW wired mortise lock?
Both are electrified mortise locks meant to be wired at the opening. The BEST 45HW is a heavy duty wired electromechanical mortise lock in the 45HW Wired Mortise Series with 12V/24V operation. The Corbin Russwin ML20906 is an ANSI/BHMA Grade 1 mortise lockset with motorized electric latch retraction, a 2-3/4 inch backset, a 3/4 inch latchbolt, and an ANSI straight lip strike with 1-1/8 inch lip to center, ordered in Fail Safe or Fail Secure with an optional request-to-exit switch. Motorized latch retraction pulls the latch fully back for free ingress, where a solenoid-driven electromechanical lock controls the outside lever instead.
21) Is a Dormakaba E-Plex E5086 a substitute for a Corbin Russwin ML20906?
They solve access differently. The Dormakaba E-Plex E5086 is a Grade 1 entry/egress electronic pushbutton and card mortise lock in a back-to-back configuration, so both sides carry a reader and the lock decides access on its own. The Corbin Russwin ML20906 is a keyed mortise lockset with Fail Safe/Fail Secure electrified operation, a 6-pin L4 keyway with interchangeable core and less-cylinder ordering options, and motorized electric latch retraction driven by an external access control system. Choose the E5086 where the door manages its own credentials, and the ML20906 where the panel does.
22) Can a Schlage LE Series or ENGAGE wireless mortise lock take the place of a Corbin Russwin ML20906?
Only on the right opening. The Schlage Electronics LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader, mobile-enabled deadbolt with LED and Greenwich trim, right hand, rated 3 hours fire. The LEBMB-ADD is a Grade 2 mobile-enabled mortise lock with push button and LED covering privacy, office and apartment functions on 1-3/4 inch doors, also 3 hours fire. Both communicate wirelessly and are handed or function-fixed at order. The Corbin Russwin ML20906 is field reversible, is offered across 612 Satin Bronze, 613 Satin Bronze Oil-Rubbed, 626 Satin Chrome and 630 Satin Stainless Steel, and hardwires into the access control system with motorized latch retraction, which is what a door on an existing wired head end and a card reader above the frame is expecting.
23) What mortise lock covers a dormitory or corridor opening if the ML20906 electrified function is more than the door needs?
The Sargent 7925 is a heavy duty Grade 1 corridor/dormitory function mortise lock in the 7900 Series with rose trim and a single cylinder deadbolt, which handles a resident door mechanically. The Corbin Russwin ML20906 is a Grade 1 electrified mortise lockset in Fail Safe or Fail Secure with request-to-exit monitoring available and rose or escutcheon trim options, and is the choice when the corridor door has to answer to a central access control system and report its door position back.
24) Are a Schlage PM010 or an L0170 comparable to a Corbin Russwin ML20906?
No, and mixing them up on a takeoff leaves an opening unsecured. The Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, and the Schlage L0170 is a Grade 1 heavy duty half dummy trim in the L Series with a dummy function, meaning it does not latch at all. The Corbin Russwin ML20906 is a keyed single cylinder electrified mortise lockset with a 3/4 inch latchbolt, a 2-3/4 inch backset, and Fail Safe/Fail Secure operation. Passage and dummy trim carry no cylinder and no electrical control.
25) Can a Sargent 4874 mortise deadbolt or an Alarm Lock DL4500 be used in place of an ML20906?
Not on a latching door. The Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset in the 4870 Series, and the Alarm Lock DL4500 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. Both throw a bolt only and require separate latching hardware to keep the door closed. The Corbin Russwin ML20906 combines a lever, a 3/4 inch latchbolt, and electrified control in one mortise case with an ANSI straight lip strike, 1-1/8 inch lip to center.
