Corbin Russwin ML2022-LL Grade 1 Mortise Storeroom Lockbody with Quick Reversible Latchbolt

Commercial-Grade Mortise Storeroom Lock for High-Traffic Institutional and Industrial Applications

The Corbin Russwin ML2022-LL is a Grade 1 mortise storeroom lockbody from the ML2000 Series, engineered to meet the demanding requirements of commercial, institutional, industrial, and government facilities. Constructed of heavy-gauge steel with a 1" stainless steel deadbolt and a patented Quick Reversible latchbolt, this lockbody delivers ANSI function F14 operation — latchbolt by grip either side when the deadbolt is retracted, deadbolt by key either side, and latchbolt retracted by key either side. Designed for 1-3/4" (44mm) standard door thickness with field-reversible handing, the ML2022-LL provides life safety and security in a single door prep. The included ANSI straight lip strike measures 4-7/8" (124mm) x 1-1/4" (32mm) x 1-1/8" (29mm) lip to center.

Corbin Russwin ML2022-LL-626 – Frequently Asked Questions

1) Does the Corbin Russwin ML2022 come with levers and trim, or is it just the lock case?
Lock case only. The ML2022-LL is a mortise lockbody, so levers, roses or escutcheons, and the cylinder are ordered separately. The ANSI straight lip strike is included and measures 4-7/8 x 1-1/4 inches with a 1-1/8 inch lip to center. Budget for trim plus a 6-pin L4 keyway cylinder (or another manufacturer's cylinder, which the case accepts) to finish the opening.
2) What does ANSI F14 storeroom function actually do on the door?
With the ML2022 storeroom function, the outside lever is always fixed, so the door is locked to the outside at all times and entry is by key. Free egress from the inside. The description lists it as ANSI function F14: latchbolt by grip either side when the deadbolt is retracted, deadbolt by key either side, and latchbolt retracted by key either side. That combination of a latch plus a 1 inch stainless deadbolt is why it gets used on stockrooms, mechanical rooms, and IT closets.
3) Do I have to order the ML2022 lock handed for a left or right door?
No handed ordering needed. The ML2022 uses the patented Quick Reversible latchbolt, so handing is reversed in the field without opening the lock case. One part number covers left and right hand, and left or right hand reverse openings, which is the reason multi-family and MRO shops stock it as a single line item.
4) Is the ML2022 mortise lock approved for a 3-hour fire rated door?
Yes. The ML2022-LL is UL/cUL listed to UL10C positive pressure and carries a 3-hour rating on single doors up to 4 by 10 feet and pairs up to 8 by 10 feet. It also lists ANSI/BHMA A156.13 Series 1000 Grade 1 for operational and security, ADA A117.1, California State Fire Marshal, and windstorm/hurricane certification, which is the package an institutional spec usually calls for.
5) Can I key this Corbin Russwin mortise lock into my existing master key system?
Yes on both counts: it works with new or existing Corbin Russwin key systems, and the case accepts most other manufacturers' cylinders, so an existing Schlage or Sargent system can often be carried over with the right mortise cylinder and cam. The standard cylinder spec is brass, 6-pin L4 keyway, 0-bitted. For high security work it can be paired with Corbin Russwin Pyramid or Access 3 cylinders.
6) What is a cross-brand equivalent to the Corbin Russwin ML2022 mortise lock body?
The Accentra 8800FL Series mortise lock body is the closest cross-brand counterpart. Like the Corbin Russwin ML2022, it is a Grade 1 mortise lock body with field reversible handing, so either can be specified where the opening calls for a mortise case that can be re-handed in the field. The ML2022 itself is the storeroom function of the ML2000 Series, supplied as a lock body only with a 3/4 inch latchbolt and an ANSI straight lip strike, 4-7/8 inch x 1-1/4 inch x 1-1/8 inch. Keying and trim are specified separately in both cases.
7) What finishes does the ML2022 lockbody come in and do they matter if the case is hidden?
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 finish shows on the exposed armored front and strike, so match it to the lever trim already on your other openings.
8) Is this mortise lock tough enough for a school corridor or hospital door?
It is a Grade 1 commercial lock, cycle tested to 14.5 million cycles (UL Verification ID V875753), with a heavy-gauge steel case and a two-piece anti-friction latchbolt that closes with less force. The auxiliary latchbolt deadlocks the main latch at 9/16 inch (14mm) effective throw, which is what stops a credit card attack. That is the level of duty schools, hospitals, and warehouses specify.
9) Is there an electrified version of this lock for access control?
The ML2022-LL itself is mechanical, not electronic. For electric operation Corbin Russwin offers Motorized Electric Latch Retraction (MELR) on the ML20900 series, so if the opening is tied to a card reader or remote release, specify from that series rather than the straight mechanical ML2022 body.
10) Do I need a separate deadbolt on a storeroom door if I use the ML2022?
No. The ML2022 combines a latch and a one-piece stainless steel deadbolt with 1 inch throw in a single mortise case, so one door prep covers both security and life safety. That saves cutting a second pocket for an auxiliary deadbolt and keeps free egress intact, since the inside grip retracts the latch.
11) What is the alternative if I am standardizing on a different brand of Grade 1 mortise lock body?
The closest cross-brand equivalent we carry is the Accentra 8800FL Series Grade 1 mortise lock body, which is also Grade 1 and also field reversible for handing. Choose on key system: if the building is already on Corbin Russwin keyways, the ML2022 keeps that intact. If your shop stocks Accentra trim and cylinders, the 8800FL keeps trim and keying consistent across the facility.
12) Do I need to order a separate lock body for each hand when replacing mortise cases across a building?
No, not with either of the two Grade 1 mortise bodies that cover this need. The Corbin Russwin ML2022 is field reversible, and the Accentra 8800FL Series mortise lock body is also field reversible, so one body stocked can serve left and right hand openings. That lets a facility carry a single storeroom body part number for its mortise doors rather than splitting inventory by hand.
13) I need a complete lockset, not just a mortise case - is the Corbin Russwin ML2022 the right item?
The Corbin Russwin ML2022 is a mortise lock body only, meaning lever trim and cylinder are ordered separately. The Accentra 8800FL Series item is likewise a mortise lock body. If you are replacing only a failed case in an existing mortise prep and reusing the trim and cylinder already on the door, a body-only part is what you want; if the door needs new trim as well, specify the trim package alongside the body.
14) Can I change the ML2022 to a different lock function later, like classroom or office?
Function changes within the ML2000 Series are handled at the lockbody level, and the family supports 12 functions configurable from one ML2054 lockbody. The ML2022 as ordered is the storeroom function (ANSI F14). If you expect functions to change across a building, spec the multi-function body instead of swapping cases door by door.
15) Is there a vandal resistant option for exposed or behavioral health openings?
Yes. The ML2000VR variant uses vandal-resistant stainless steel escutcheons with tapered edges and Torx pin tamper-resistant screws. Behavioral Health trim (BHSS/BLSS) is also offered in the ML2000 trim range, along with Museo and Vineyard designs, and trim is thru-bolted for alignment and added security.
