Corbin Russwin ML2013 626 – Frequently Asked Questions

1) Will the Corbin Russwin ML2013 mortise deadbolt fit a 1-3/4 inch commercial door?
Yes. The ML2013 is built for 1-3/4 inch (44mm) door thickness, which is the standard commercial door. Backset is 2-3/4 inches (70mm), and the lockcase is 5-7/8 x 4 x 15/16 inches, so the pocket has to be routed for a full ML2000 mortise case, not a bored deadbolt hole. Optional thicknesses are available if your doors run heavier than 1-3/4.
2) Does the ML2013 have a latch, or is it deadbolt only?
Deadbolt only. The ML2013 is the Cylinder x Thumbturn deadbolt function: key from the outside, thumbturn from the inside, with a 1 inch stainless steel deadbolt throw. There's no knob or lever operation and nothing holds the door closed on its own, so it goes on an opening that already has a latching device, or on a door with a closer and a separate latch. If you need latching and deadbolt in one case, you want a different ML2000 function.
3) Will the ML2013 deadbolt work into my existing ANSI strike prep?
It ships with a wrought brass, bronze, or stainless ANSI straight lip strike, 4-7/8 x 1-1/4 with 1-1/8 inch lip to center. If your frame is already cut for a standard ANSI 4-7/8 mortise strike, the new strike drops into that prep. The bolt itself throws 1 inch, so the strike box behind the frame needs the depth to take it.
4) Can I key the ML2013 into my building's existing Corbin Russwin key system?
Yes. The ML2000 Series works with new or existing Corbin Russwin key systems and accepts most other manufacturers' cylinders. Standard supply is a brass conventional 6-pin L4 keyway cylinder, 0-bitted, so your locksmith pins it to your system. There's also a 7-Pin LFIC less core option if your facility runs interchangeable cores and you want to load your own.
5) Is the ML2013 mortise deadbolt approved for a fire-rated door?
It's UL/cUL listed and UL10C positive pressure rated, good for a 3-hour fire door up to 4' x 10' single or 8' x 10' pair. It also carries ANSI/BHMA A156.13 Series 1000 Grade 1 for both operational and security, ADA A117.1, California State Fire Marshal, and windstorm/hurricane certification. That combination is what specifiers on schools, hospitals and government work are usually chasing.
6) What is the closest equivalent to a Corbin Russwin ML2013 mortise deadbolt from another manufacturer?
The ML2013 is a deadbolt-only mortise lock operated by key outside and thumbturn inside, with a 1 inch deadbolt throw. The nearest cross-brand equivalent is the Kaba Ilco 185 Series mortise lock, which is also a deadbolt function and is supplied with no handing. Where a key is wanted on both faces instead of a thumbturn, the Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset, matching the ML2013 backset. Choose by which side needs the thumbturn: the ML2013 gives thumbturn egress inside, the 4874 requires a key from both sides.
7) I need a mortise lock with a latch and a lever, not just a deadbolt. What should I order instead of the ML2013?
The ML2013 is a deadbolt-only function, so it will not latch the door or carry a lever. For a latching Grade 1 mortise lockset, the Accentra 8805FL is a Grade 1 storeroom mortise lock from the 8800 Series with an Arcadia lever, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option on a 1-3/4 inch door. For an office function instead of storeroom, the Cal-Royal NM8050 is a Grade 1 office/entrance mortise lockset with an auxiliary deadlatch. All three latch the door; the ML2013 secures it with a 1 inch deadbolt only.
8) Which mortise deadbolt should I use if I want keypad access instead of a key?
The ML2013 is a mechanical, keyed mortise deadbolt with a conventional 6-pin L4 keyway. If codes are wanted in place of keys on a deadbolt opening, the Alarm Lock DL4500 Series is a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad, fitting doors 1-5/8 to 1-7/8 inch. Note the door thickness difference: the ML2013 is built for a 1-3/4 inch door, which sits inside the DL4500 range, so a 1-3/4 inch door suits either, while thicker doors point back to the ML2013.
9) I need the door to lock and unlock from an access control system. What mortise lock replaces the ML2013 for that?
The ML2013 is a non-electronic mortise lock, mechanical only. For an electrified mortise lock on the same opening, the Schlage L9092EU 03A is a heavy duty electric lock/unlock outside lever mortise lock with request to exit, keyed outside, running on 12/24VDC on a 1-3/4 inch door, matching the ML2013 door thickness. The Command Access ML190 Series is a heavy-duty motorized storeroom mortise lock with field selectable EL/EU operation on 24VDC, and the BEST 45HW is a heavy duty wired electromechanical mortise lock with 12V/24V operation. All three require power to the door; the ML2013 does not.
10) Do I have to order the ML2013 handed, or can it be reversed on site?
Order it and re-hand it in the field. The ML2000 case uses a patented quick reversible latchbolt, so the hand is changed without taking the lock case apart. For a locksmith carrying stock, that means one part covers both hands of an opening.
11) What do I need to specify when ordering an ML2013, besides finish?
Three things. Cylinder type: standard conventional cylinder, or 7-Pin LFIC less core if you're supplying your own interchangeable cores. Keying: keyed different is the standard, keyed alike if you want a group of doors on one key. And finish. There's also a free-text field for special cylinder or keying requirements, which is where a master key system or a specific keyway goes.
12) Should I use a mortise deadbolt like the ML2013 or an electronic deadbolt on this door?
The ML2013 is fully mechanical, no power and no wiring, which is why it holds up on doors that just need to be locked hard and left alone. If you need audit trail or code access on the same door, the Alarm Lock DL4500 Series is a Grade 1 electronic mortise deadbolt with keypad, though it fits 1-5/8 to 1-7/8 inch doors rather than the ML2013's 1-3/4. For a double cylinder mortise deadbolt with key both sides instead of a thumbturn, the Sargent 4874 shares the same 2-3/4 inch backset.
13) I need a key on both sides instead of a thumbturn. Is there an alternative to the ML2013?
The ML2013's inside is a thumbturn, single cylinder, so it always allows free egress by hand from the inside. For key both sides, the Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset, the same backset the ML2013 uses. Be aware that double cylinder on an egress door is restricted by code in most jurisdictions, which is exactly why the thumbturn version exists.
14) If I'm standardizing a whole building on Corbin Russwin ML2000, can I mix the ML2013 with latching functions on the same door prep?
Yes, that's the point of the series. Every ML2000 function uses the same mortise pocket, 2-3/4 inch backset and 8 x 1-1/4 inch armored front, and one ML2054 lockbody covers 12 functions. So a maintenance department can prep every door the same way, run the ML2013 deadbolt where a door only needs bolting, and put storeroom or classroom functions elsewhere, all on one keyway and one finish.
15) Is a Sargent 130KB mortise thumbturn a substitute for the ML2013?
No. The Sargent 130KB is a mortise thumbturn, a trim piece for an 8200 Series lock, and the Sargent 130W is a mortise thumbturn with a round backplate for the 7800 Series. Neither contains a lock mechanism. The ML2013 is a complete mortise deadbolt lock with a 1 inch deadbolt and a 6-pin cylinder. If an existing mortise lock body already has a thumbturn hub and only the turn piece failed, the 130KB or 130W replaces that part; if the door needs the bolt itself, the ML2013 is the lock.
16) For a classroom or dormitory door, is the ML2013 the right mortise lock or should I use something else?
The ML2013 is a Grade 1 deadbolt-only function, so it does not provide classroom or dormitory operation on its own. For a dormitory opening the Sargent 7925 is a Grade 1 heavy duty dormitory exit function mortise lock with rose trim and a single cylinder deadbolt. For classroom function, the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with auxiliary deadlatch for a 1-3/4 inch door, and the Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset with ANSI strike, also for 1-3/4 inch doors. The ML2013 suits an opening where the latch is handled separately and only the bolt is required.
17) What Grade 1 mortise lock should I use on a behavioral health or anti-ligature door instead of the ML2013?
The ML2013 is a Grade 1 mortise lock with a thumbturn on the inside, which is a projecting grip. On anti-ligature openings the TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in stainless steel with passage function, and the MRX-A-01 is a Grade 1 heavy duty ligature resistant arch trim mortise lockset, both for 1-3/4 inch doors, the same door thickness the ML2013 is built for. For a push/pull hospital opening, the Marks USA 5PDN is a Grade 1 ligature resistant ADA compliant mortise push/pull paddleset in satin stainless steel.
18) Which mortise lock offers credential or card access on a Grade 1 door if the ML2013 keyed deadbolt is not enough?
The ML2013 is mechanical and keyed only. For credential-based access on a Grade 1 mortise opening, the TownSteel FME-2000 Series is a Grade 1 heavy duty classroom mortise lockset with RFID technology for 1-3/4 inch doors, the same thickness the ML2013 is built for, and the Schlage LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating. The Dormakaba E-Plex E5086 is a Grade 1 electronic pushbutton and card entry/egress mortise lock in a back to back configuration.
19) What finishes does the Corbin Russwin ML2013 come in?
Fourteen: 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. All fourteen are offered with either cylinder type, so you can match an existing building standard like 626 satin chrome and still run interchangeable cores.
20) Is the ML2013 heavy duty enough for a high-traffic door in a school or hospital?
The ML2000 Series case is heavy-gauge steel and has been UL cycle tested to 14.5 million cycles (Verification ID V875753), well past the A156.13 Grade 1 requirement it's certified to. Trim and armored front are brass or bronze. On a deadbolt-only function the cycle count matters less than on a latching lock, but it tells you what the case is built to.
21) How far apart are the cylinder and thumbturn on an ML2000 mortise lock?
Center to center, knob or lever to cylinder is 3-5/8 inches (92mm), and knob or lever to thumbturn is 2-7/16 inches (62mm). Those spacings drive the trim cutouts and the escutcheon prep, so they're the numbers to check against an existing door if you're swapping trim or reusing a prep.
22) Is there a non-keyed mortise lock alternative if I do not need the ML2013 cylinder?
Yes. The ML2013 is keyed with a single cylinder. Where no key is required, the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for a 1-3/4 inch door, the Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating, and the Hager 3810S is a Grade 1 passage mortise lock with rose on a 2-3/4 inch backset, which is the same backset the ML2013 uses. Field reversibility carries across between the ML2013 and the MA101, so hand can be set at the door with either.
23) Will an Emtek Brisbane or Memphis mortise entrance set work as a replacement for the ML2013?
No. The Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton and 3106 Manhattan mortise entrance locksets are dummy function, meaning they are non-operating trim with no working bolt. The ML2013 is a Grade 1 keyed mortise deadbolt with a 1 inch stainless deadbolt throw. Use an Emtek dummy set on an inactive leaf where the appearance must match, and the ML2013 where the door has to actually lock.
24) For a privacy bathroom door, should I specify the ML2013 or a dedicated privacy mortise lock?
The ML2013 is keyed from the outside with a thumbturn inside, which is an entry security arrangement rather than a privacy function. For a restroom or bedroom door, the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt for a 1-3/4 inch door, the same door thickness as the ML2013, and the Hager 3840S is a Grade 1 privacy mortise lock on a 2-3/4 inch backset, matching the ML2013 backset, for doors 1-3/4 to 2 inch.
