Corbin Russwin 544F77-626 – Frequently Asked Questions

1) What exactly is the Corbin Russwin 544F77 escutcheon, and is the lock included?
It is the trim plate only, not a lock. The 544F77 is a wrought "N" escutcheon for the ML2000 Series mortise lock, cut for a cylinder and a grip (pull handle) on the same plate, measuring 7-1/2 x 2-1/4 inches. You mount it over an existing or separately ordered ML2000 mortise lockbody. If you need the lockbody, latch, strike, and cylinder, that is a complete ML2000 mortise lockset, not this part.
2) Will the 544F77 escutcheon work on a left-hand door as well as a right-hand door?
It is field reversible, so one part covers both hands. The ML2000 lock behind it uses a Quick Reversible latchbolt that re-hands without opening the lock case, so a single escutcheon plus a single lockbody can be set up for either swing on site.
3) Which ML2000 mortise lock trim configuration does the 544F77 escutcheon fit?
It matches ML2000 configurations that use a thumbturn lever and grip, with the escutcheon prepped for both a cylinder and a grip on the inside. The related spacing on the ML2000 trim is 3-5/8 inches center to center from knob/lever to cylinder and 2-7/16 inches from knob/lever to thumbturn, so the door prep has to match that layout.
4) Does the 544F77 fit a 1-3/4 inch commercial door?
Yes. The ML2000 Series is built around 1-3/4 inch (44mm) doors as standard with optional thicknesses available, and it uses a 2-3/4 inch (70mm) backset. If your doors are thicker than standard, the thickness option has to be specified on the lock side of the order.
5) Is this escutcheon acceptable on a fire rated door in a dormitory or hospital corridor?
The ML2000 Series it belongs to is UL/cUL listed to UL10C positive pressure and carries a 3-hour fire door rating up to 4 ft x 10 ft single or 8 ft x 10 ft pair, along with ANSI/BHMA A156.13 Grade 1 and ADA A117.1 compliance. That covers the corridor and dormitory openings this Corridor/Dormitory function trim is used on.
6) Can I use my existing cylinder in the 544F77 escutcheon?
The escutcheon is prepped for a mortise cylinder, and the ML2000 platform works with new or existing Corbin Russwin key systems and accepts most other manufacturers' cylinders. Corbin Russwin's standard cylinder is brass, 6-pin, L4 keyway, supplied 0-bitted so a locksmith can key it to your system.
7) I need to match the other trim in my building. What finishes does the 544F77 come in?
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. Matching an existing opening is usually a matter of reading the BHMA number stamped or specified on the trim already installed, most often 626 or 630 in commercial work.
8) Will the existing strike still work if I am only replacing the escutcheon trim?
Yes, changing the escutcheon does not touch the latching. The ML2000 latchbolt throws 3/4 inch (19mm) with a 9/16 inch deadlocking auxiliary latch and a 1 inch stainless deadbolt, against an ANSI straight lip strike 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center. Only the plate on the door face changes.
9) Is escutcheon trim or sectional trim the right choice for my ML2000 mortise locks?
Escutcheon trim like the 544F77 is a single full plate covering the lever, cylinder, and grip, so it hides older or rougher door prep and gives one thru-bolted assembly. Sectional trim uses separate roses and is a lighter look but leaves more of the door face exposed. Both are offered across the ML2000 range, including status indicator options on sectional and escutcheon trim, so pick on appearance and how much prep you need covered.
10) Is the 544F77 heavy enough for a high traffic dormitory or school corridor?
It is a Grade 1 commercial part. The ML2000 lock it trims is certified to ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1 and has been cycle tested to 14.5 million cycles. The escutcheon itself is wrought brass, bronze, or stainless depending on the finish you order, and thru-bolted trim keeps it aligned under heavy use.
