Corbin Russwin 438F90-626 – Frequently Asked Questions

1) Is the 438F90 for a privacy lock or a keyed lock?
It is the standard plate for privacy function with emergency release only. On that function the opening in the plate takes the emergency release, not a full keyed cylinder. If the door uses a keyed function, you need the plate specified for that function instead.
2) What finishes does the Corbin Russwin 438F90 key plate come in?
Eight finishes: 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 619 satin nickel, 625 bright chrome, 626 satin chrome, 630 satin stainless steel, and BSP black suede powder coat. Order to match the rest of the trim on the opening, since a replacement plate sits directly beside the existing lever rose.
3) Does replacing the key plate on an ML2000 affect the fire rating on the door?
The ML2000 mortise lock is UL/cUL listed to UL10C positive pressure and rated for 3-hour fire doors up to 4 ft x 10 ft single or 8 ft x 10 ft pair. Using the manufacturer's own trim parts, like the 438F90 plate and its supplied screws, is how you keep that assembly as listed. Substituting a non-Corbin plate on a rated door is where inspections go wrong.
4) Does the key plate have to match the handing of the door?
No. The plate is a round 1-3/8 inch cast trim piece and installs either hand. Handing on the ML2000 is a function of the lockbody, which uses a quick reversible latchbolt that re-hands without opening the lock case.
5) Where does the key plate sit relative to the lever on an ML2000 sectional trim?
On ML2000 sectional trim the center-to-center spacing from knob or lever to cylinder is 3-5/8 inches (92mm), and lever to thumbturn is 2-7/16 inches (62mm). That is the hole pattern already in your door, so the replacement plate drops onto the existing prep with no new boring.
6) I manage a building standardized on Corbin Russwin ML2000 mortise locks. Can I stock this plate as a repair part across all of them?
Yes, for privacy-function openings with cast "V" sectional escutcheon trim. The ML2000 is ANSI/BHMA A156.13 Series 1000 Grade 1 operational and security, so it is the typical building standard for restrooms and similar privacy doors. Stock the plate in the finish your doors already carry and keep the two supplied screws with it.
7) What is the 438F90 key plate made of?
Cast brass or bronze, plated or coated to the finish you order. Cast trim is what the ML2000 sectional program uses on commercial openings rather than stamped plate.
8) Does the 438F90 work on a thicker-than-standard door?
Door thickness is handled by the lockbody and spindle, not the plate. Standard ML2000 setup is a 1-3/4 inch (44mm) door with optional thicknesses available, and the plate itself is surface trim that mounts with the two #6 x 1/2 inch screws regardless.
