Corbin Russwin 429F41-619 – Frequently Asked Questions

1) What exactly does the Corbin Russwin 429F41 screw pack include it for?
The 429F41 is the fastener pack for the armored front on Corbin Russwin ML2000 Series mortise locksets. It is the screws that hold the armored front plate to the lock case, not the armored front itself and not the lockbody. If your armored front is damaged or missing, you need the front plate as well as this pack.
2) What finishes does the Corbin Russwin 429F41 screw pack come in, and does it need to match my lock?
Six finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 619 satin nickel, and 626 satin chrome. Order the finish that matches the armored front, since the screw heads sit exposed in the edge of the door where a mismatch shows.
3) Does using this screw pack keep my ML2000 lock's fire rating and Grade 1 certification intact?
Yes, it is the manufacturer part for the job, which is what matters on a rated opening. The ML2000 Series carries ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1, is UL/cUL listed to UL10C positive pressure, and is rated for 3-hour fire doors up to 4 x 10 feet single or 8 x 10 feet pair. Substituting generic fasteners on the armored front of a rated lock is not a manufacturer-approved installation.
4) Will the 429F41 screw pack work on any ML2000 mortise lock, or only certain functions?
It is specified for the ML2000 Series armored front, which is common across the series regardless of lock function. The armored front on these locks is 8 x 1-1/4 inches in wrought brass, bronze or stainless steel, and this pack is the manufacturer hardware for fastening it. Functions like the 12 configurable from an ML2054 lockbody share that same front.
5) I manage a building with Corbin Russwin ML2000 locks on every door. Can I stock one screw pack finish for all of them?
Only if all your armored fronts are the same finish. The pack ships in a single finish per order (605, 606, 612, 613, 619 or 626), so a mixed building needs the matching finish per opening group. Satin chrome 626 is the most common commercial spec, so that is usually the one to keep on the shelf first.
6) Will the 429F41 fit my ML2000 lock if the door is thicker than 1-3/4 inches?
Yes. The armored front screws fasten into the lock case at the door edge, and case dimensions do not change with door thickness. The ML2000 is 1-3/4 inch (44mm) standard with optional thicknesses available, and the lock case stays 5-7/8 x 4 x 15/16 inches with a 2-3/4 inch backset across them.
7) My ML2000 latch is dragging on the strike. Is the armored front screw pack the fix?
Usually not on its own. Loose armored front screws can let the front shift slightly, and this pack replaces them, but drag more often traces to strike alignment. The ML2000 latchbolt is a two-piece anti-friction design with 3/4 inch (19mm) throw and the ANSI straight lip strike is 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center, so check the strike position against that before assuming fasteners.
8) Do I need to pull the ML2000 lock out of the door to replace the armored front screws?
No. The armored front is fastened at the edge of the door, so the screws come out with the door closed prep exposed and the lock case in place. Handing is also not a factor here, since the ML2000 uses a quick reversible latchbolt that re-hands without opening the lock case, and the armored front is symmetrical about the case.
9) Is the Corbin Russwin 429F41 a commercial-only part?
It is catalogued for commercial door hardware use, matching where the ML2000 mortise lock gets specified: offices, schools, healthcare, retail, industrial, multi-tenant residential and government buildings.
