Corbin Russwin 423F54-626 – Frequently Asked Questions

1) Which Corbin Russwin mortise locks does the 423F54 armored front fit?
The 423F54 armored front scalp is made for ML2000 Series mortise lockcases, specifically the ML2024, ML2020, ML2030 and ML2022 functions. It covers both deadbolt and latchbolt applications, so it suits the lock cases that carry a deadbolt as well as latch-only functions. It is not a universal front plate, so if your lockcase is another manufacturer's mortise body it is the wrong part.
2) What size is the 423F54 armored front plate?
It measures 8 inches by 1-1/4 inches. That 1-1/4 inch width is the standard ML2000 mortise front width, so it lines up with an existing ML2000 door edge prep without recutting the mortise pocket.
3) How does the armored front attach to the lock case?
It fastens to the ML2000 lockcase front with machine screws. On ML2000HS and ML2000VR configurations the front uses security Torx screws instead, so you will need the matching security bit to remove or install it on those high-security and vandal-resistant lock bodies.
4) Is the 423F54 armored front acceptable on a fire-rated opening?
The ML2000 Series mortise lock it fits is UL/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 armored front keeps the assembly as listed; a substitute plate is not part of that listing.
5) Does the armored front cover the deadbolt as well as the latch?
Yes. The 423F54 is cut for both the deadbolt and the latchbolt, so it suits ML2000 functions with a 1 inch throw stainless steel deadbolt alongside the 3/4 inch throw anti-friction latchbolt and the 9/16 inch auxiliary deadlocking latch. Latch-only functions use a different front.
6) Will replacing the armored front change my door prep or backset?
No. The armored front is a cover scalp over the lockcase front, not a functional part of the lock. The ML2000 lockcase stays at a 2-3/4 inch backset with a 5-7/8 x 4 x 15/16 inch case, and the front plate simply screws over it. Swapping the scalp for finish or damage reasons does not touch the door prep.
7) What grade is the ML2000 lock this armored front belongs to?
ANSI/BHMA A156.13 Series 1000, Operational and Security Grade 1, with UL cycle testing at 14.5 million cycles. For a facility standardizing on Grade 1 mortise hardware, keeping the original armored front on the case is part of maintaining that assembly.
8) What door thickness does the ML2000 mortise lock with this front suit?
Standard is 1-3/4 inch (44mm) doors, with optional thicknesses available from the series. The 8 inch armored front sits in the door edge and is unaffected by thickness as long as the lockcase is the correct one for the door.
9) Does the armored front need to be handed?
Handing is set by the lockcase, not the scalp. ML2000 lockbodies use a quick reversible latchbolt that re-hands without opening the case, so a field re-hand does not require a different armored front.
