Corbin Russwin 581F96 626 – Frequently Asked Questions

1) What exactly is the Corbin Russwin 519F12 thumbturn lever packet, and does it include the mortise lock?
The 519F12 is a thumbturn lever packet only, a rose and thumbturn assembly used to restore the interior locking function on a Corbin Russwin ML2000 Series mortise lock. No lock body, no cylinder, no exterior trim. Buy it when the thumbturn or its rose is worn, broken, or missing and the lock case itself is still good.
2) Will the 519F12 thumbturn fit any Corbin Russwin mortise lock, or only ML2000?
It is built for the ML2000 Mortise Lock Series only, as a factory-spec drop-in for compatible ML2000 configurations. Older Corbin Russwin mortise cases outside the ML2000 platform are not covered by it, so identify the case as ML2000 before ordering the packet.
3) What rose sizes does the Corbin Russwin 519F12 thumbturn packet come in?
Two sizes are offered: 3 inch and 3-1/2 inch. Measure the existing rose on the door, or the diameter of the paint or wear ring left behind if the old rose is gone, so the new one covers the same footprint on the face of the door.
4) What finishes is the 519F12 ML2000 thumbturn available in?
Satin brass (606) and satin chrome (626). Note the pairing: satin brass comes on the 3 inch rose and satin chrome on the 3-1/2 inch rose, so the finish and the rose size are tied together in what is offered. Match the finish code stamped on your other ML2000 trim to keep a building's openings consistent.
5) Is this a genuine Corbin Russwin part or an aftermarket copy?
Genuine OEM, sourced from Corbin Russwin to factory specification. For institutional buyers standardizing on ML2000, that matters: aftermarket thumbturns often sit proud of the rose or bind the spindle, while the OEM packet keeps the original spindle engagement and trim profile.
6) Can I replace just the thumbturn instead of the whole mortise lockset?
That is the point of the packet. It addresses wear or damage in the rose and thumbturn portion of the trim without pulling the lock case, which keeps a maintenance call short and avoids re-keying or re-prepping the door. Facility crews and locksmiths can service it as a discrete component.
7) I have an ML2000 privacy or classroom function lock with a bad interior turn. Is this the right part to order?
If the failed piece is the interior thumbturn and its rose, yes, provided your lock is an ML2000 case. The packet restores the interior locking action only. If the problem is the latch not retracting, the deadbolt itself, or the outside trim, the fault is in the lock case or exterior trim and the thumbturn packet will not fix it.
8) Is the 519F12 thumbturn rated for commercial traffic or is it a residential part?
Commercial. It is an ML2000 platform component intended for commercial door hardware duty, which is why it shows up in offices, schools, hospitals, government buildings, retail, warehouses, and multi-tenant residential. It is not a light-duty residential thumbturn.
