Corbin Russwin 404F86-8 – Frequently Asked Questions

1) What is the Corbin Russwin 404F86-8 and which locks does it go in?
The 404F86-8 is a hub alignment bracket, an internal service part for the Corbin Russwin ML2000 Series mortise lock. It holds the hub in correct position inside the lock case so the knob or lever spindle turns true. It is not a complete lockset and it is not trim: if the whole lockbody is worn or damaged, you need an ML2000 lockbody, not this bracket.
2) My lever sags or feels sloppy on a Corbin Russwin ML2000 mortise lock. Is the hub alignment bracket what I need?
A sloppy or drooping lever on an ML2000 usually traces back to hub alignment inside the case, and the 404F86-8 bracket is the part that keeps the hub positioned for consistent operation. Before ordering, rule out the simpler causes: loose thru-bolted trim (ML2000 trim is thru-bolted specifically to hold alignment) and a worn spindle. If the trim is tight and the lever still drops, the internal bracket is the next thing to replace.
3) Will this bracket fit ML2000 locks on doors of any thickness or backset?
It is an internal case component, so the door itself does not affect fit. What matters is that the lock is an ML2000: the case is heavy-gauge steel at 5-7/8 x 4 x 15/16 inches with a 2-3/4 inch backset, standard on 1-3/4 inch doors with optional thicknesses available. If the mortise pocket in your door holds a case of other dimensions, it is not an ML2000 and this bracket is the wrong part.
4) I manage a building with a mix of Corbin Russwin mortise locks. How do I confirm mine are ML2000 before ordering this bracket?
Pull one lock and check the case and front. An ML2000 case measures 5-7/8 x 4 x 15/16 inches with an 8 x 1-1/4 inch armored front, a 3/4 inch throw two-piece anti-friction latchbolt, a 9/16 inch deadlocking auxiliary latch, and on deadbolt functions a 1 inch throw stainless deadbolt. Center to center from knob or lever to cylinder is 3-5/8 inches, and to thumbturn 2-7/16 inches. Match those and the 404F86-8 applies across the fleet.
5) Does replacing the hub bracket change the handing of an ML2000 mortise lock?
No. Handing on the ML2000 is set by its patented quick reversible latchbolt, which is re-handed without disassembling the lock case. The 404F86-8 bracket is a hub component and does not determine hand. If your problem is a wrong-hand latch, re-hand the latchbolt instead of buying parts.
6) Is this a genuine Corbin Russwin OEM part or an aftermarket bracket?
Genuine Corbin Russwin, part number 404F86-8, made to the tolerances the ML2000 platform requires. For an ANSI/BHMA A156.13 Grade 1 lock that is also UL/cUL listed for 3-hour positive pressure fire doors, OEM internals matter: substituting non-original parts inside a fire-rated lock case can compromise the listing on that opening.
7) Does this bracket work in electrified ML2000 locks such as the MELR versions?
The bracket is an ML2000 Series hub part, and the electrified ML20900 series with Motorized Electric Latch Retraction is built on the same ML2000 platform. On any electrified lock, isolate power before opening the case. Note that MELR involves motor and wiring assemblies that this mechanical bracket has nothing to do with, so a latch that will not retract on command is an electrical fault, not a hub alignment issue.
8) Can I use this part on a residential mortise lock?
No. The 404F86-8 is a commercial part for the Corbin Russwin ML2000 Grade 1 mortise lock, the type used in offices, schools, healthcare, retail, industrial buildings, multi-tenant residential common areas, and government facilities. Residential mortise locks use entirely different internals.
