Corbin Russwin 466F51-626 – Frequently Asked Questions

1) What exactly comes in the Corbin Russwin 466F51 trim adapter pack?
The 466F51 is a trim alignment (adapter) pack for the ML2000 and ML2000HS mortise lock series, sized for 1-3/4 inch doors. It contains the components needed to align the trim correctly on the door, and it is regularly furnished with working trim. It is not a lock or a trim set by itself, so it does not replace a lockbody or an escutcheon.
2) Will the 466F51 adapter pack work on a 1-3/8 inch door?
No. The 466F51 is built for 1-3/4 inch (44mm) doors only, which is the standard commercial door thickness. Every orderable version is the 1-3/4 inch door option. For a thinner or thicker leaf you need the adapter pack matched to that thickness, since the ML2000 lock is offered with optional door thicknesses.
3) Which trim does the 466F51 adapter support?
It supports Cast Knob Half Dummy Trim used with the "M" and "N" escutcheons on the ML2000 and ML2000HS series. If your opening uses a different escutcheon family or sectional trim, this is not the alignment pack for it.
4) What finishes does the Corbin Russwin 466F51 come in, and can I match the rest of my doors?
Eight finishes are offered: 605 bright brass, 612 satin bronze, 613 satin bronze oil-rubbed, 619 satin nickel, 625 bright chrome, 626 satin chrome, 630 satin stainless steel, and BSP black suede powder coat. Order the same finish code as the trim already on the opening so the adapter and escutcheon read as one assembly.
5) Do I need the trim adapter pack if I'm just ordering a new ML2000 lockset with trim?
Usually not as a separate line. The adapter pack is regularly furnished with working trim on ML2000 and ML2000HS orders. You buy the 466F51 on its own when you are adding half dummy cast knob trim later, replacing damaged alignment hardware, or completing a trim swap in the field on a 1-3/4 inch door.
6) Does using this adapter affect the fire rating of an ML2000 opening?
The ML2000 mortise lock is UL/cUL listed to UL10C positive pressure, rated for 3-hour fire doors up to 4 ft by 10 ft single or 8 ft by 10 ft pair, and the trim is thru-bolted for proper alignment and security. The 466F51 is the manufacturer's own alignment hardware for that trim, so installing it as furnished keeps the assembly as the lock was tested, rather than shimming with field-made parts.
7) What grade and backset is the ML2000 mortise lock this adapter is used with?
The ML2000 is ANSI/BHMA A156.13 Series 1000, Operational and Security Grade 1, with a 2-3/4 inch (70mm) backset and a heavy-gauge steel lockcase measuring 5-7/8 x 4 x 15/16 inches. That 2-3/4 inch backset is the standard commercial mortise backset, so the trim and adapter land on the normal mortise prep.
8) Will my existing keys and cylinders still work after I change the ML2000 trim?
Changing escutcheon trim and adding the alignment pack does not touch keying. The ML2000 works with new or existing Corbin Russwin key systems and accepts most other manufacturers' cylinders; the standard cylinder is brass, 6-pin L4 keyway, 0-bitted. Trim spacing is fixed at 3-5/8 inches center to center from knob or lever to cylinder, and 2-7/16 inches to a thumbturn, so the escutcheon must match that layout.
9) Do I have to specify handing for the 466F51 adapter pack?
Handing is set by the lock, not the alignment pack. The ML2000 lockbody is handed but uses a patented quick reversible latchbolt, so it can be re-handed without disassembling the lock case. Order the adapter by door thickness and finish.
