Corbin Russwin 684F55-9 – Frequently Asked Questions

1) Will the 684F55-9 fit any Corbin Russwin mortise lock, or only the ML2000?
Only the ML2000 Mortise Lock Series. The 684F55-9 fixed stop is built specifically for that platform as a drop-in replacement with no modification. If the lock in your door is a different Corbin Russwin series, or another brand's mortise lock, this is the wrong part number and you need the stop listed for that lock's own parts breakdown.
2) Is the 684F55-9 an aftermarket stop or a genuine Corbin Russwin part?
Genuine OEM. It comes out of the Corbin Russwin lock parts program, so the fit, form, and function match what shipped in the lock originally. For institutional buyers standardized on ML2000 hardware, that matters: using the factory stop keeps the lock at its original operating specification rather than close enough.
3) Is this stop rated for commercial door traffic or just light residential use?
Commercial. The 684F55-9 belongs to Corbin Russwin's commercial mechanical lock line, and the ML2000 platform it serves is used in offices, schools, hospitals, government buildings, retail, multi-tenant residential, and industrial facilities. It is not a residential-grade part.
4) Does replacing the fixed stop on an ML2000 require any door or frame modification?
No. The 684F55-9 is a drop-in replacement inside the ML2000 lock case, so the work stays at the lock itself. Your existing mortise pocket, strike prep, and trim are untouched, which is why this repair is usually faster than swapping the whole lock body.
5) How many part numbers do I order for the 684F55-9 fixed stop?
One. The 684F55-9 is sold as a single configuration with no handing, finish, or size choices to specify, so a property manager or maintenance buyer stocking ML2000 spares just orders the quantity of locks being serviced. Order one per lock case you are repairing.
