Corbin Russwin 402F30 626 – Frequently Asked Questions

1) Will the Corbin Russwin 402F30 armored front fit my ML2000 mortise lock?
The 402F30 is the 1-1/4 inch standard armored front for the Corbin Russwin ML2000 and ML2000HS mortise lock series, and it covers deadbolt, latchbolt and auxiliary latch configurations. Check the width of the front currently on your lock: this one is 1-1/4 inches, so it suits an ML2000 case prepped for the standard front rather than a narrower or wider front. It is the faceplate assembly that shows on the door edge, not the lock body itself.
2) Do I need to order a left hand or right hand armored front for the ML2000?
No handing to specify. The 402F30 armored front is non-handed, so one part serves left and right hand openings. Handing on the ML2000 lives in the lock case, and that case uses a quick reversible latchbolt that re-hands without disassembly, so a swing change on the door does not mean a different front.
3) Will the 402F30 armored front line up with my existing ANSI strike and 2-3/4 inch backset prep?
Yes, on standard ML2000 prep. The series runs a 2-3/4 inch (70mm) backset with an ANSI straight lip strike at 4-7/8 x 1-1/4 x 1-1/8 inch lip to center. Bolt projections through the front are 3/4 inch (19mm) on the latchbolt, 9/16 inch (14mm) effective on the deadlocking auxiliary latch, and 1 inch (25mm) on the stainless deadbolt. Replacing the front does not change any of those, so the door and frame prep you already have stays good.
4) Is the ML2000 lock still fire rated after I change the armored front?
The ML2000 series is UL/cUL listed to UL10C positive pressure and carries a 3-hour fire door rating up to 4 x 10 feet single or 8 x 10 feet pair. Using the correct genuine ML2000 front keeps the assembly as listed, which is the reason to fit the series part rather than a generic faceplate on a rated opening. The series is also ANSI/BHMA A156.13 Series 1000 Grade 1 for operational and security, and meets ADA A117.1.
5) What size is the ML2000 standard armored front and how much door edge does it cover?
It measures 8 x 1-1/4 inches. That length runs the full ML2000 mortise pocket on the door edge, covering the latchbolt, auxiliary latch and deadbolt openings in one plate. The lock case behind it is 5-7/8 x 4 x 15/16 inches, so the front is longer than the case to bridge the prep.
6) What door thickness does the ML2000 armored front work on?
1-3/4 inch (44mm) is the standard door thickness for the ML2000 series, which is the usual commercial door. Optional thicknesses are available in the series, so on a thicker door confirm the lock was built for it before ordering front parts.
7) What finishes does the Corbin Russwin 402F30 armored front come in, and how do I match the other doors in my building?
Nine finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 619 satin nickel, 625 bright chrome, 626 satin chrome, 629 bright stainless steel and 630 satin stainless steel. Those are BHMA finish codes, so match the number stamped or specified on the trim already installed rather than matching by eye. 626 and 630 are the two you will find most often on commercial openings.
8) Does this armored front work on an ML2000 with a deadbolt as well as one with just a latch?
One front covers all three. The 402F30 is cut for deadbolt, latchbolt and auxiliary latch, so it fits ML2000 functions with a deadbolt (an entrance or classroom-with-deadbolt setup) and those without. Center-to-center spacing on the series is 3-5/8 inches (92mm) knob or lever to cylinder, and 2-7/16 inches (62mm) knob or lever to thumbturn, so the trim layout above the door edge is unchanged.
9) Is the Corbin Russwin 402F30 armored front suitable for a high-traffic commercial opening?
It is a commercial part. The ML2000 platform is verified to 14.5 million cycles by UL (Verification ID V875753) and rated ANSI/BHMA Grade 1 for both operation and security, which is the tier specified for school, healthcare, office and multi-tenant corridor doors. The armored front itself is wrought brass, bronze or stainless steel depending on finish.
