Corbin Russwin 544F89 630 – Frequently Asked Questions

1) Is the 544F89 the inside or the outside escutcheon?
Inside. The 544F89 is the interior-face plate, and it is specifically the one that finishes the thumbturn lever side of an ML2000 mortise lock. If you're replacing a damaged plate on the corridor side, this is not the part.
2) Can I use this escutcheon with a regular lever trim instead of a thumbturn?
No. The Wrought N 544F89 is machined for thumbturn lever configurations in the ML2000 series and is not interchangeable with other lever types. A standard lever-only inside trim uses a different escutcheon in the same family.
3) Will this Corbin Russwin escutcheon work on a ML2000 mortise lock, or do I need a different series part?
It is made for the ML2000 Mortise Lock Series specifically, as a genuine OEM replacement plate. It is trim only, not a lock body, so the mortise case, spindles and cylinder stay in the door and you are just re-plating the inside face.
4) Can a Schlage Electronics CO Series escutcheon be used in place of the Corbin Russwin 544F89 on an ML2000 mortise lock?
No. The Corbin Russwin 544F89 is a Wrought N escutcheon made for the inside face of a 1-3/4 inch door on the ML2000 Mortise Lock Series in a thumbturn lever configuration, and it is a mechanical replacement part with no electronics. The Schlage Electronics 47260707 is an exterior escutcheon for CO100 Series cylindrical and mortise locks and carries a keypad, so it serves an access control trim rather than a mechanical ML2000 thumbturn. The two are not dimensionally or functionally interchangeable; an ML2000 thumbturn opening needs the Corbin Russwin part.
5) What finish does the 544F89 come in, and will it match my other stainless ML2000 trim?
One finish: 630 Satin Stainless Steel. That is the standard BHMA number for satin stainless, so it will match other ML2000 trim ordered in 630 across a building. If your existing openings are in a brass or bronze finish, this plate will stand out.
6) Will a decorative stainless escutcheon plate like the MS Sedco ESC cover an ML2000 mortise prep?
No. The MS Sedco ESC is a decorative stainless escutcheon plate for R4 and R6 round switches, so it is sized to a push switch rather than to a mortise lock prep. The Corbin Russwin 544F89 is the Wrought N escutcheon for the ML2000 Mortise Lock Series, inside face, thumbturn lever configuration on a 1-3/4 inch door. Use the 544F89 to restore an ML2000 assembly and the MS Sedco plate only around a round actuator switch.
7) Is this a genuine Corbin Russwin part or an aftermarket copy?
Genuine OEM Corbin Russwin lock part, catalogued as a commercial-grade replacement component for the ML2000 platform. That matters on a repair where the rest of the assembly is original: the plate lines up with the existing prep and matches the factory profile.
8) Is a satin stainless escutcheon suitable for a healthcare or school corridor?
Yes. Satin stainless is corrosion resistant and holds up in high-traffic commercial settings, and the 544F89 is classified as a commercial part used in offices, schools, hospitals, government buildings, retail and multi-tenant residential. For a patient-room or restroom door where the occupant needs to secure the inside, the thumbturn configuration this plate serves is the usual choice.
