Corbin Russwin 624F49-626 – Frequently Asked Questions

1) Which ML2054 functions does the Corbin Russwin 624F49 armored front fit?
The 624F49 armored front is built for the Corbin Russwin ML2054 multi-function mortise lockbody in functions 10, 32, 42, 52, 53, 55 and 57, plus the 20906 functions. It carries the latchbolt and auxiliary latch. If the lock in your door is set to a function outside that list, this is not the front for it, so pull the function off the lock case before you order.
2) What size is the Corbin Russwin 624F49 armored front and will it drop into my existing mortise pocket?
Wrought brass, bronze or stainless steel, 8 x 1-1/4 inches. That 1-1/4 inch width is the standard mortise front, so it matches an ML2054 pocket already prepped for a 1-1/4 inch front. If your door was prepped for a 1-inch face, the 624F49 is the wrong width and the cut-out will show.
3) Will the 624F49 latchbolt still catch my existing ANSI strike?
The two-piece anti-friction latchbolt on the 624F49 measures 5/8 x 1 inch with a 3/4 inch (19mm) throw, and the auxiliary latch gives 9/16 inch (14mm) effective throw and deadlocks the latch. Those are the same throws the ML2054 ships with, so an opening already running an ANSI straight lip strike (4-7/8 x 1-1/4 inch, 1-1/8 inch lip to center) keeps latching without touching the frame. What changes fit is gap, not the front: if the door has gone out of alignment, the 3/4 inch throw is what you have to work with.
4) Do I have to order the 624F49 front handed for a left or right hand door?
Handing is not a separate order line here. The ML2054 uses a patented quick reversible latchbolt, so the latch re-hands without taking the lock case apart. Set it in the field to match the door swing.
5) My auxiliary latch is worn and the door can be loided open. Is the 624F49 the part that fixes it?
Yes, that is exactly what this part carries. The 624F49 assembly includes the auxiliary latchbolt, which deadlocks the main latch with 9/16 inch of effective throw and is the piece that stops a latch from being carded. Replacing the front assembly restores that function without swapping the whole ML2054 lock body.
6) Is the 624F49 a springlatch or a deadlatch part, and does it include a deadbolt?
Springlatch. The latchbolt type on the 624F49 is a springlatch with a deadlocking auxiliary latch behind it, and the assembly covers the latchbolt and auxiliary latch only. The ML2054's 1 inch stainless deadbolt with its 1 inch throw is a separate component of the lock, not part of this front.
7) What finishes can I get the Corbin Russwin 624F49 armored front in to match the other doors in my building?
Ten finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613E dark oxidized satin bronze equivalent, 619 satin nickel, 625 bright chrome, 626 satin chrome, 629 bright stainless, 630 satin stainless, and BSP black suede powder coat. For a fleet of openings running Corbin Russwin trim, order the front in the same BHMA number that is stamped on the existing hardware, most commonly 626 or 630 on commercial work.
8) Does replacing the armored front change the door prep or backset on my ML2054 opening?
No. The ML2054 runs a 2-3/4 inch (70mm) backset in a 1-3/4 inch (44mm) door as standard, and the front is a face component, so swapping in the 624F49 does not move the backset, the cylinder spacing (3-5/8 inch center to center from knob or lever) or the thumbturn spacing (2-7/16 inch). Existing door and frame prep is untouched.
9) Can I use the 624F49 on a fire rated opening and keep the rating?
The ML2054 lock the 624F49 serves is UL/cUL listed and UL10C positive pressure rated for 3 hour fire doors up to 4 by 10 feet single and 8 by 10 feet pair, and the lock is ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1. Using the manufacturer's own front assembly is what keeps that listing intact on a rated door, which matters if your facility gets inspected against NFPA 80.
10) Do I need to rekey or change cylinders when I replace the armored front on an ML2054?
No. The front assembly carries the latchbolt and auxiliary latch, not the cylinder. The ML2054 takes a brass 6-pin L4 keyway cylinder, 0-bitted as standard, works with new or existing Corbin Russwin key systems, and accepts most other manufacturers' cylinders, so your keying stays exactly as it is.
11) The doors in our building get heavy traffic and the latches are dragging on the strike. Will this part hold up?
The 624F49 uses a two-piece mechanical latchbolt with an anti-friction insert, which is the design that cuts the force needed to close the door and takes the drag off a misaligned strike. The ML2054 platform it belongs to is Grade 1 and UL cycle verified to 14.5 million cycles. For high traffic corridors that is the right class of part; a dragging latch on a heavy door is usually the anti-friction insert being worn out.
