Corbin Russwin 544F76-626 – Frequently Asked Questions

1) Is the Corbin Russwin 544F76 the whole lock or just the trim plate?
It's trim only. The 544F76 is a wrought "N" escutcheon plate for the ML2000 Series mortise lockset, sold as a replacement part. It does not include a lock case, latch, cylinder or lever. If the lock body inside the door is bad, you need an ML2000 lockset, not this plate.
2) What size is the 544F76 escutcheon plate, and will it cover my old trim's footprint?
The plate measures 7-1/2 inches by 2-1/4 inches. Hold that against what is on the door now: if the existing escutcheon is larger, you will see paint or finish shadow around the edges once the new one goes on, so plan on refinishing the door face.
3) What does "grip only" mean on the 544F76 escutcheon - can I use it with a lever?
Grip-only means this escutcheon is prepped for a door pull grip, not a knob or lever spindle. If the opening uses a lever or knob on that side, this is the wrong plate and you need the lever or knob escutcheon trim from the ML2000 trim range instead.
4) Do I have to order the 544F76 escutcheon handed left or right?
No. The door hand is field reversible on this escutcheon, so one part covers both left and right hand openings. That matters for property managers stocking spares: one part number covers the whole building instead of two.
5) Will the 544F76 escutcheon fit a mortise lock from another brand?
No. It's cut for the Corbin Russwin ML2000 mortise lock case, which is a heavy-gauge steel case 5-7/8 x 4 x 15/16 inches with cylinder-to-knob spacing of 3-5/8 inches and knob-to-thumbturn of 2-7/16 inches. Another manufacturer's mortise case will not line up with those hole centers.
6) Is the 544F76 escutcheon OK on a fire-rated door?
The ML2000 mortise lock system it trims is UL and cUL listed to UL10C positive pressure, 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 keeps that listing intact; substituting a non-listed plate is what puts a rated opening out of compliance.
7) Can the 544F76 go on the inside or the outside of the door?
Either side. The escutcheon can be installed inside or outside on an ML2000 mortise opening, so on a pair of matching plates you order the same part number twice.
8) What finishes does the 544F76 wrought escutcheon come in for matching existing building hardware?
Thirteen 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 most commercial corridors the existing trim is 626 satin chrome or 630 satin stainless.
9) Is this escutcheon heavy enough for a dormitory corridor or high-traffic school door?
It's a commercial, Grade 1 part for the ML2000 mortise family, which is certified to ANSI/BHMA A156.13 Series 1000 operational and security Grade 1 - the top grade for mortise locks and what school, dorm and healthcare corridor doors are normally specified to. The wrought construction is the heavier of the escutcheon options.
10) My ML2000 lock works fine but the corridor trim is dented - do I need to pull the lock out of the door to swap the escutcheon?
No. Replacing the escutcheon is a trim change on the door face; the mortise case stays in the pocket. The ML2000 also uses a quick-reversible latchbolt, so even if you are re-handing the opening at the same time you don't have to open the lock case.
11) Does the 544F76 escutcheon work on a door thicker than 1-3/4 inches?
Standard for the ML2000 mortise system is 1-3/4 inch (44mm) doors, with optional thicknesses available. The plate itself is not the limiting part - thickness is handled by the lock case and thru-bolt hardware, so specify the thick-door option on the lockset side when the door is over 1-3/4 inches.
12) What backset does the ML2000 mortise prep use that this escutcheon trims?
2-3/4 inches (70mm), which is the standard commercial mortise backset. If the existing prep in your door is 2-3/8 inch bored, that's a cylindrical opening and neither this trim nor an ML2000 mortise case will drop into it without a mortise pocket being cut.
