Corbin Russwin 427F39-626 – Frequently Asked Questions

1) Is the Corbin Russwin 427F39 a complete mortise lock or just the outside plate?
It's the outside escutcheon plate only, a cast trim for the outside face of the door. There's no lock case, no cylinder and no lever in it. It's made for ML2000 Series mortise locks in the Cylinder and Grip configuration, so you supply the lockbody, cylinder and grip separately.
2) Will this escutcheon work on a 1-3/4 inch commercial door?
Yes. The ML2000 platform this trim belongs to is built for 1-3/4 inch (44mm) doors as standard, with optional thicknesses available, and the trim is thru-bolted for alignment and added security.
3) Does the cylinder hole in this plate line up with my existing ML2000 prep?
It follows the ML2000 spacing, which is 3-5/8 inch (92mm) center to center from knob/lever to cylinder on a 2-3/4 inch (70mm) backset lock case. If your door is prepped to that ML2000 template, the cast plate drops on without new boring.
4) Is the 427F39 handed, and can I use it on either a left or right hand door?
It's the outside R escutcheon, so it is a handed plate. The ML2000 lock case itself is quick reversible and can be re-handed without disassembling the case, but the cast trim is not, so order the plate to match the door's hand.
5) Can I use this trim on a 3 hour fire rated door?
The ML2000 mortise lock assembly this escutcheon trims is UL/cUL listed and UL10C positive pressure rated, good for 3-hour fire doors up to 4 ft x 10 ft single or 8 ft x 10 ft pair. The trim has to be the listed ML2000 trim for that rating to hold, which is what this cast escutcheon is.
6) Do I need a Corbin Russwin cylinder behind this escutcheon, or will another brand work?
The ML2000 lock accepts most other manufacturers' cylinders and can be keyed into new or existing Corbin Russwin key systems. Standard Corbin Russwin supply is a brass 6-pin L4 keyway cylinder, 0-bitted. So if your building is already on a different keyway, you can keep it.
7) What finish does the 427F39 escutcheon come in?
626 satin chrome. If the other openings in your building are brass or bronze trim, this plate won't match them, so plan on a matched set for a fleet standardization job.
8) What ANSI grade is the ML2000 lock this escutcheon goes with?
ANSI/BHMA A156.13 Series 1000, Operational and Security Grade 1, with UL cycle testing at 14.5 million cycles (Verification ID V875753). For a school or hospital corridor where you need documented Grade 1, that's the spec line to quote. The platform also meets ADA A117.1 and carries California State Fire Marshal and windstorm/hurricane certification.
9) What else do I have to order to finish an ML2000 cylinder and grip opening?
Besides this outside cast escutcheon you'll need the ML2000 lock case (an ML2054 body covers 12 functions on its own), the cylinder, the grip for the outside, the inside trim, and the strike. The ML2000 strike is ANSI straight lip, 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center.
10) Can I get a status indicator or Museo style trim instead of this plain cast escutcheon?
Yes, the ML2000 trim range includes Museo, Vineyard, and Behavioral Health (BHSS/BLSS) designs, plus locked/unlocked status indicator options on both sectional and escutcheon trim. The 427F39 is the plain cast cylinder-only outside plate, so if you want an indicator for a restroom or an exam room, specify an indicator escutcheon rather than this one.
11) Will the existing strike catch if I replace trim and lock with an ML2000?
The ML2000 latchbolt is a two-piece anti-friction unit measuring 5/8 x 1 inch with a 3/4 inch (19mm) throw, plus a deadlocking auxiliary latch at 9/16 inch (14mm) effective throw and a 1 inch (25mm) throw stainless deadbolt. A 3/4 inch throw needs a strike pocket deep enough to take it; an ANSI straight lip 4-7/8 inch strike is the matched part.
12) Does the mortise case for this trim need a deep enough door stile?
The ML2000 lockcase is heavy-gauge steel at 5-7/8 x 4 x 15/16 inches (149 x 102 x 24mm) with an 8 x 1-1/4 inch armored front in wrought brass, bronze, or stainless. That 4 inch case depth plus the 2-3/4 inch backset is why mortise locks go in stiles wide enough to be mortised, not in narrow aluminum stile doors.
13) Is this escutcheon suitable for residential use?
It's a commercial part. The ML2000 platform is specified for offices, schools, healthcare, retail, government buildings, multi-tenant residential, and industrial or warehouse facilities. On a single-family house a Grade 1 mortise trim is more hardware than the door prep usually supports.
