Corbin Russwin ML2062 Grade 1 Mortise Intruder Deadbolt Lockbody with Field Reversible Handing

Commercial-Grade Intruder Deadbolt Mortise Lock for High-Traffic Security Applications

The Corbin Russwin ML2062 is a Grade 1 mortise intruder deadbolt lockbody from the ML2000 Series, engineered for demanding commercial, institutional, industrial, and government environments. Conforming to ANSI function F33, this lockbody allows the latchbolt to be operated by grip from either side unless the outside grip is locked by projection of the deadbolt, while the deadbolt can be thrown or retracted by key from either side. Constructed of heavy-gauge steel with a 1" stainless steel deadbolt and a 3/4" latchbolt, the ML2062 is designed for 1-3/4" (44mm) standard door thickness and features field-reversible handing for flexible installation. The included ANSI straight lip strike measures 4-7/8" (124mm) x 1-1/4" (32mm) x 1-1/8" (29mm) lip to center, ensuring a precise and secure fit.

Corbin Russwin ML2062-LL-626 – Frequently Asked Questions

1) What exactly comes with the Corbin Russwin ML2062, and do I need to order trim and a cylinder separately?
The ML2062 is a mortise lock body only. You get the lock case with the latchbolt and deadbolt plus the ANSI straight lip strike; levers, roses or escutcheons, and the cylinder are ordered separately. Plan on a 6-pin cylinder for the deadbolt side, and note the case accepts most other manufacturers' cylinders as well as new or existing Corbin Russwin key systems.
2) What does the F33 intruder deadbolt function actually do on the door?
With the ML2062, the latchbolt works by lever from either side until the deadbolt is thrown, which locks the outside lever. The deadbolt itself is thrown or retracted by key from either side. That is ANSI function F33, the classic classroom-security style lockdown where the room can be secured without stepping into the corridor if you carry the key.
3) Will the ML2062 fit a 1-3/4 inch door with a 2-3/4 inch backset mortise pocket?
Yes. The ML2062 is built for 1-3/4 inch (44mm) doors with a 2-3/4 inch (70mm) backset, and the steel case measures 5-7/8 x 4 x 15/16 inches with an 8 x 1-1/4 inch armored front. Optional door thicknesses are available if your opening is heavier than standard.
4) Do I have to specify handing when I order this mortise lock body?
Handing is set in the field. The ML2062 uses the patented Quick Reversible latchbolt, so you re-hand it without opening the lock case. One body covers left and right hand openings, which is why it is a sensible stock item for a maintenance shop.
5) Can I reuse the existing strike, or do I need to cut the frame?
The ML2062 ships with an ANSI straight lip strike, 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center, so a frame already prepped for ANSI mortise strike takes it as is. The latchbolt throws 3/4 inch with a 9/16 inch deadlocking auxiliary latch, and the stainless deadbolt throws a full 1 inch, so the strike box has to be deep enough for that bolt.
6) Is the ML2062 approved for a fire-rated opening?
Yes. The ML2000 Series lock is UL/cUL listed to UL10C positive pressure and carries a 3-hour rating on single doors up to 4' x 10' and pairs up to 8' x 10'. It also meets ANSI/BHMA A156.13 Grade 1 and ADA A117.1, and is listed by the California State Fire Marshal and windstorm/hurricane certified.
7) What is a cross-brand equivalent to the Corbin Russwin ML2062 mortise lock body?
The closest cross-brand counterpart is the Accentra 8800FL Series Grade 1 mortise lock body, which is also a field reversible Grade 1 mortise lock body sold as a case without trim. The ML2062 is a Grade 1 mortise lockbody in the ML2000 Series with the intruder deadbolt function, a 3/4 inch latchbolt, and field reversible handing. If your opening specifically requires the intruder deadbolt arrangement, stay with the ML2062 and confirm the function on the Accentra case before substituting, since the two lines use different function numbering and different trim and cylinder interfaces.
8) Can I use an Accentra 8800FL mortise lock body to replace a Corbin Russwin ML2062 in an existing door?
Both are Grade 1 mortise lock bodies with field reversible handing, so both fit the general class of mortise pocket prep, but they are not drop-in for one another. The ML2062 is built around the ML2000 Series trim, cylinder and spindle arrangement and ships with the ANSI straight lip strike measuring 4-7/8 inches by 1-1/4 inches with 1-1/8 inch lip to center. Swapping brands typically means new trim, a new strike and a new cylinder, and re-verifying the mortise pocket and cross-bore locations. If the surrounding doors already carry Corbin Russwin trim and keying, keeping the ML2062 preserves the match across the fleet.
9) Is this lock body tough enough for a school corridor or a hospital that cycles constantly?
It is built for that traffic. The case is heavy-gauge steel, the deadbolt one-piece stainless, and UL cycle testing was carried out to 14.5 million cycles (Verification ID V875753) against Operational and Security Grade 1 under A156.13 Series 1000. The two-piece anti-friction latchbolt also lowers closing force, which helps on doors with strong closers.
10) How much room does the lever need above the cylinder and thumbturn on the trim?
Spacing on the ML2062 is 3-5/8 inches (92mm) center to center from lever to cylinder and 2-7/16 inches (62mm) from lever to thumbturn. Match those numbers when you pick escutcheon or sectional trim so the prep lines up.
11) Can I get a visual indicator showing whether the room is locked?
Yes, the ML2000 Series offers status indicator options for locked/unlocked visibility on both sectional and escutcheon trim. Trim families include Museo, Vineyard, and Behavioral Health (BHSS/BLSS), and the ML2000VR vandal-resistant option adds stainless escutcheons with tapered edges and Torx pin tamper-resistant screws. All trim is ordered separately from the lock body.
12) Is there an electrified version of this mortise lock?
The ML2062 itself is a mechanical lock body with no electrical components. If you need electric latch retraction, that is the Motorized Electric Latch Retraction (MELR) option offered on the ML20900 series rather than on this body.
13) I need a mortise lock body but not the deadbolt function. What should I look at instead of the ML2062?
The ML2062 carries the intruder deadbolt function, in which the latchbolt works by lever from either side unless the outside lever is locked by projecting the deadbolt, and the deadbolt throws or retracts by key from either side. If your opening does not need a keyed deadbolt, look at another function within the ML2000 Series rather than a different lock type, since the same lock case supports twelve functions and keeps the trim, strike and keying consistent with the rest of the doors. Across brands, the Accentra 8800FL Series Grade 1 mortise lock body is the comparable case to specify a non-deadbolt function against.
14) Is a mortise deadbolt lock body like the ML2062 the same as adding a separate deadbolt above a cylindrical lockset?
No. The ML2062 is a single mortise lock case that carries both the latchbolt and a deadbolt in one pocket, with the intruder deadbolt function, so one prep serves both. A separate auxiliary deadbolt above a cylindrical lockset is a second device with its own bore, its own strike and its own cylinder to key. If the door is already prepped for a mortise case, the ML2062 keeps the opening to one pocket; if you are comparing across brands, the Accentra 8800FL Series Grade 1 mortise lock body is the equivalent one-case approach.
15) For a Grade 1 institutional standardization, does it matter whether I spec the ML2062 or the Accentra 8800FL body?
Both are Grade 1 mortise lock bodies, so either meets a Grade 1 line on the drawing. The practical decision is keying and trim standardization: the ML2062 works with new or existing Corbin Russwin key systems and accepts most other manufacturers' cylinders, and it is UL/cUL listed to UL10C positive pressure for 3-hour fire doors. If a facility is already on Corbin Russwin keyways and ML2000 trim, standardizing on the ML2062 avoids carrying two trim and cylinder inventories.
16) What finishes does the Corbin Russwin ML2062 come in for matching existing hardware?
Fourteen finishes: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 oil-rubbed satin bronze, 613E dark oxidized 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. The visible parts are the armored front and strike, available in wrought brass, bronze, or stainless steel.
