Corbin Russwin 402F29-626 – Frequently Asked Questions

1) What is the Corbin Russwin 402F29 armored front and which locks does it fit?
The 402F29 is the faceplate that covers the edge of the door on a Corbin Russwin mortise lock. It is built for the ML2000 and ML2000HS Mortise Lock Series, and it is the version machined for a lockbody carrying a deadbolt, latchbolt, auxiliary latch and toggle. Wrong cutout pattern means the bolts will not pass through, so match the front to the function set in the case, not just the series.
2) Is the Corbin Russwin 402F29 the standard 1-1/4 inch width or the narrow one?
Standard width, 1-1/4 inches, with an overall front size of 8 x 1-1/4 inches. Corbin Russwin also builds narrow-width fronts for tighter door edges, so measure the existing faceplate before ordering. If yours is narrower than 1-1/4 inches, the 402F29 will overhang the mortise pocket.
3) Can I replace a damaged mortise lock faceplate without pulling the whole lock out of the door?
Replacing just the front is the point of a part like the 402F29. The lock case stays in the mortise; the front is what takes the abuse from strike contact, keys, and painters. What you cannot do is swap in a front with a different bolt layout. Deadbolt, latchbolt, auxiliary latch and toggle openings must line up with what your ML2000 case actually carries, and the 1-1/4 inch width has to match your door edge prep.
4) Can this front be used on a 3-hour fire rated door assembly?
The ML2000 mortise lock it serves 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. Keep the lock complete with its correct armored front to stay within that listing. The series is also ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1 and meets ADA A117.1.
5) What material and finishes does the 402F29 armored front come in?
Fronts are wrought brass, bronze, or stainless steel depending on finish. Ten finishes are offered: 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 facility standardizing on one look, 630 satin stainless is the usual commercial match.
6) Do I have to specify handing when I order an armored front for an ML2000 mortise lock?
The ML2000 lockbody is handed but uses a quick reversible latchbolt, so handing is changed without opening the lock case. The armored front itself is a symmetrical edge plate with the bolt cutouts, so what matters at order time is that the cutout pattern matches your function set, deadbolt plus latchbolt plus auxiliary latch and toggle in the case of the 402F29.
7) Will a 402F29 front clear a 1 inch deadbolt throw and a 3/4 inch latch throw?
Yes. The ML2000 uses a one-piece stainless deadbolt with a 1 inch (25mm) throw and a two-piece anti-friction latchbolt with a 3/4 inch (19mm) throw, plus an auxiliary latchbolt at 9/16 inch (14mm) effective throw. The 402F29 is cut for all three of those plus the toggle, which is why it is the front specified for that function set.
8) What door thickness and backset does the ML2000 lock this front belongs to use?
Standard is a 1-3/4 inch (44mm) door with a 2-3/4 inch (70mm) backset, and optional thicknesses are available from the factory. The lock case itself is 5-7/8 x 4 x 15/16 inches, so the mortise pocket has to be prepped to that, and the 8 x 1-1/4 inch front covers the edge of it.
9) Does a replacement front let me keep my existing cylinders and keying?
Yes, nothing about the front touches the keying. The ML2000 lock works with new or existing Corbin Russwin key systems and accepts most other manufacturers' cylinders; the factory standard cylinder is brass, 6-pin L4 keyway, 0-bitted. Center to center spacing is 3-5/8 inches (92mm) knob or lever to cylinder and 2-7/16 inches (62mm) knob or lever to thumbturn.
10) Is this front suitable for a high traffic entrance in a school or hospital?
It is a commercial part for a lock line tested to 14.5 million cycles under UL verification ID V875753, well past the Grade 1 minimum. That is the reason the ML2000 gets specified on office, education, healthcare, government, retail, industrial and multi-tenant residential openings. In those buildings the front is usually the first thing to wear or get gouged, which is why it is sold separately.
