Corbin Russwin 377F80 626 – Frequently Asked Questions

1) Is the 377F80 for a cylinder-and-grip trim configuration or a lever?
It's the inside master ring escutcheon for cylinder and grip configurations on the ML2000 series. If the door has lever trim rather than a knob/grip with a cylinder through the escutcheon, this is the wrong plate for that opening.
2) Can a Schlage CO Series escutcheon be used in place of the Corbin Russwin 377F80 on an ML2000 mortise lock?
No. The Corbin Russwin 377F80 is a wrought M escutcheon inside master ring made as a genuine replacement part for the ML2000 and ML2000HS mortise lock series in a cylinder and grip configuration, so it is a mechanical trim piece matched to that lock body. The Schlage Electronics 47260707 is a CO Series exterior escutcheon for cylindrical and mortise locks on the CO100 with a keypad and is supplied with fasteners and an O-ring, so it carries electronic keypad trim rather than a mechanical master ring. If the door has an ML2000 mortise lock, stay with the 377F80; the CO Series escutcheon belongs to a CO100 keypad opening.
3) Does the 377F80 escutcheon come with the lock or the cylinder?
No. The 377F80 is a replacement escutcheon plate only, the inside master ring for cylinder and grip trim. The mortise lock body, cylinder, grip and any spindles are separate items you'd order alongside it when rebuilding an ML2000 trim.
4) Can I use a Schlage CO Series escutcheon in place of the Corbin Russwin 377F80?
No. The Schlage Electronics escutcheons, such as the 47260707 exterior escutcheon for CO-100 cylindrical and mortise locks and the 47260708 exterior escutcheon for CO-100 exit trim, are keypad trims for Schlage's electronic CO line. The 377F80 is a mechanical inside master ring for the Corbin Russwin ML2000 series. They serve different lock platforms and are not interchangeable.
5) Which side of the door does the 377F80 mount on?
Inside. It's the interior-side master ring escutcheon, so it finishes the room side of an ML2000 or ML2000HS mortise installation. If you're replacing a damaged plate on the corridor or exterior face, you need the matching outside escutcheon instead.
6) Is the MS Sedco ESC escutcheon plate an alternative to the Corbin Russwin 377F80?
No, they solve different problems. The MS Sedco ESC is a decorative stainless escutcheon plate for R4 and R6 round switches, so it trims out a push switch in the switches line. The Corbin Russwin 377F80 is a wrought M escutcheon inside master ring for cylinder and grip on ML2000 and ML2000HS mortise locks, a commercial door hardware part. A lock opening needs the 377F80; an actuator switch opening needs the MS Sedco plate.
7) Is this escutcheon suitable for a high-traffic commercial building or is it residential grade?
It's a commercial-duty part, wrought construction, sold for door hardware service in offices, schools, healthcare, government buildings, retail, multi-tenant residential and industrial facilities. Facilities standardized on Corbin Russwin ML2000 hardware use it as the maintenance replacement plate.
8) We are standardizing finishes across a building. Does the Corbin Russwin 377F80 give more finish choice than the Schlage CO Series escutcheon for exit trim?
The Corbin Russwin 377F80 wrought M escutcheon is offered in ten finishes, including 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 satin bronze oil-rubbed, 619 satin nickel, 625 bright chrome, 626 satin chrome, 629 bright stainless steel, and 630 satin stainless steel. The Schlage Electronics 47260708 CO Series exterior escutcheon for exit trim is called out in aged bronze. If you are matching brass or chrome trim on existing mortise lock doors, the 377F80 range covers those tones directly.
