Corbin Russwin 488F04-626 – Frequently Asked Questions

1) What exactly is the Corbin Russwin 488F04 - is it a complete lock or just the plate?
It's the outside escutcheon plate only, a wrought "M" style plate for the ML2000 and ML2000HS mortise lock series, measuring 7-1/2 x 2-1/4 inches. No lock case, no latch, no cylinder, no lever or grip comes with it. You order it when the trim plate on an existing mortise lock is damaged, mismatched, or being refinished and the lock body itself is fine.
2) Will the 488F04 escutcheon work with a lever or knob, or only a grip handle?
Grip only. This is the outside plate for grip-only applications, so it is cut and prepped for a pull grip rather than a lever or knob rotation. If the outside of your ML2000 opening uses a lever or knob, this is the wrong plate and you need the corresponding lever or knob escutcheon trim from the ML2000 trim range.
3) Does the 488F04 escutcheon have to be ordered left hand or right hand?
No handing call-out is needed at order time. The 488F04 is field reversible, so the installer sets the hand on site. That matches the ML2000 lock body itself, which uses a quick reversible latchbolt that re-hands without opening the lock case.
4) I'm replacing trim on a 3-hour rated corridor door - can I use this escutcheon?
Yes for ML2000 openings. The ML2000 mortise lock is UL/cUL listed to UL10C positive pressure for 3-hour fire doors up to 4 by 10 feet single and 8 by 10 feet pair, and the escutcheon trim is part of that listed assembly. Keep the rest of the lock as-listed; swapping in trim from another manufacturer is what breaks a rated opening.
5) What door thickness and backset does the ML2000 trim setup assume?
Standard is a 1-3/4 inch (44mm) door with a 2-3/4 inch (70mm) backset, which is the normal commercial mortise prep. Optional door thicknesses are available on the ML2000 series, and trim for a thicker door has to be ordered for that thickness rather than shimmed.
6) Can I use the 488F04 on a lock body from another brand?
No. It is dimensioned for the Corbin Russwin ML2000 and ML2000HS mortise lock case, which is 5-7/8 x 4 x 15/16 inches with its own trim and cylinder hole centers. Trim from one mortise manufacturer does not line up with another's case. Confirm the lock body is an ML2000 family case before ordering.
7) Which finishes does the 488F04 escutcheon come in so I can match the rest of my doors?
Thirteen BHMA finishes: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 satin bronze oil-rubbed, 613E dark oxidized satin bronze equivalent, 618 bright nickel, 619 satin nickel, 625 bright chrome, 626 satin chrome, 629 bright stainless, 630 satin stainless, and 722 black oxidized bronze oil-rubbed. For a building standardized on commercial stainless trim, 630 is the usual match; 626 satin chrome is the other common institutional finish.
8) Does the escutcheon plate cover the cylinder, and what is the spacing on an ML2000?
On the ML2000 the center-to-center spacing from knob or lever to the cylinder is 3-5/8 inches (92mm), and knob or lever to thumbturn is 2-7/16 inches (62mm). Those are the hole centers the escutcheon trim is drilled to, so the plate lines up with an existing ML2000 door prep without redrilling.
9) Is this Grade 1 trim suitable for a dorm or high-traffic corridor?
It's built for exactly that. The ML2000 carries ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1, with UL cycle testing at 14.5 million cycles, and the 488F04 is catalogued for corridor and dormitory function openings. Thru-bolted trim on the series keeps the plates aligned and resists being pulled off.
10) If I'm replacing the trim, will my existing keys and cylinder still work?
The escutcheon doesn't touch keying. The ML2000 lock body works with new or existing Corbin Russwin key systems and accepts most other manufacturers' cylinders, with a brass 6-pin L4 keyway 0-bitted as the standard cylinder. Pull your existing cylinder, fit the new plate, put the cylinder back.
11) Will the existing strike still catch after I change out the escutcheon trim?
Yes, nothing about the latching changes. The ML2000 uses a two-piece anti-friction latchbolt with a 3/4 inch (19mm) throw into an ANSI straight lip strike, 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center, plus a 9/16 inch (14mm) deadlocking auxiliary latch and a 1 inch (25mm) throw stainless deadbolt. Swapping the outside plate leaves all of that in place.
