Corbin Russwin 466F40 – Frequently Asked Questions

1) What is the Corbin Russwin 466F4 and what does it actually do?
The 466F4 is a trim alignment adapter pack for Corbin Russwin ML2000 Series mortise locksets. It is not a lock or a trim set on its own. It is the hardware that positions the lever or knob trim correctly against the door face so the trim sits square and the spindle and thru-bolts land where they should. You order it alongside the ML2000 lockbody and trim, matched to your door thickness.
2) Which door thicknesses does the 466F4 adapter pack cover?
Three thicknesses: 1-3/4 inch, 1-3/8 inch, and 2-1/4 inch. You pick the one that matches the door you are working on. 1-3/4 inch is the standard commercial door and the ML2000 standard thickness; 1-3/8 inch is the common older interior door, and 2-1/4 inch covers thick or clad doors.
3) Will the 466F4 work with any Corbin Russwin mortise lock, or only certain ones?
It is made for the ML2000 Series mortise lockset line specifically. That includes the multi-function ML2054 lockbody and the ML20900 series with Motorized Electric Latch Retraction. It is not an adapter for other Corbin Russwin lock families or for other manufacturers' mortise cases.
4) I'm speccing ML2000 mortise locks for a school. What backset and lockcase do I need to prep the doors for?
The ML2000 runs a 2-3/4 inch (70mm) backset with a heavy-gauge steel lockcase measuring 5-7/8 x 4 x 15/16 inches. The armored front is 8 x 1-1/4 inches, and the ANSI straight lip strike is 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center. Cut the pocket and frame to those numbers and the 466F4 adapter handles the trim side of the install.
5) Is the ML2000 mortise lock fire rated and code compliant for a hospital corridor door?
It is UL and cUL listed with UL10C positive pressure, carrying a 3-hour fire rating up to a 4 x 10 foot single door or an 8 x 10 foot pair. It meets ANSI/BHMA A156.13 Series 1000 at Operational and Security Grade 1, ADA A117.1, California State Fire Marshal, and windstorm/hurricane certification.
6) Can I keep my existing keying if I install ML2000 locks?
Yes. The ML2000 works with new or existing Corbin Russwin key systems and accepts most other manufacturers' mortise cylinders. The standard cylinder supplied is brass, 6-pin, L4 keyway, 0-bitted so your locksmith can key it on site.
7) Do I need a trim adapter pack if my door is a standard 1-3/4 inch?
The ML2000 is built around 1-3/4 inch (44mm) as its standard thickness, so on a standard commercial door the trim mounts without any thickness correction. The 466F4 is ordered in 1-3/4 inch as well, so if your opening is one of the optional thicknesses, 1-3/8 or 2-1/4 inch, that is when getting the right adapter version matters most for the trim to pull up flush.
8) Will the ML2000 latch reach my existing frame strike?
The latchbolt is a two-piece mechanical unit with an anti-friction insert, 5/8 x 1 inch with a 3/4 inch (19mm) throw. The auxiliary latchbolt gives 9/16 inch (14mm) effective throw and deadlocks the latch. The deadbolt is one-piece stainless, 19/32 x 1-1/4 inches with a full 1 inch throw. If your frame is prepped for an ANSI straight lip strike at 4-7/8 x 1-1/4 inches, the geometry lines up.
9) What hole spacing do I need for ML2000 escutcheon or sectional trim?
Center to center from the knob or lever to the cylinder is 3-5/8 inches (92mm). Knob or lever to thumbturn is 2-7/16 inches (62mm). Those are the two spacings that decide whether existing trim prep in the door will line up.
10) Do I have to order the ML2000 handed, and can I flip it in the field?
The lock is handed, but it uses a patented Quick Reversible latchbolt, so the handing can be reversed without opening the lock case. That matters on a retrofit where the door swing on site does not match the paperwork.
11) How many door functions can one ML2000 lockbody cover for a multi-building standardization?
Twelve functions are configurable from a single ML2054 lockbody, which is why facilities standardizing across offices, classrooms, and storerooms can stock one case instead of a dozen. Trim ranges from standard sectional and escutcheon through Museo, Vineyard, and Behavioral Health (BHSS/BLSS) designs, with optional locked/unlocked status indicators on sectional and escutcheon trim.
12) How durable is the ML2000 for a high-traffic entrance?
Cycle testing puts it at 14.5 million cycles (UL Verification ID V875753), well past the Grade 1 requirement it is certified to under A156.13 Series 1000. The lockcase is heavy-gauge steel and the deadbolt is one-piece stainless. Trim is thru-bolted, which keeps it tight on doors that get pulled hard all day.
