Corbin Russwin 519F10 626 – Frequently Asked Questions

1) What is the Corbin Russwin 519F10 thumbturn lever packet, and what does it fit?
The 519F10 is the thumbturn lever component for Corbin Russwin ML2000 Series mortise locks, sold as a packet for 1-3/4 inch doors. It is the turn piece you grip on the inside of the door to throw or retract the deadbolt, not the lockbody and not a cylinder. Use it to restore an existing ML2000 lockset that has a thumbturn function, or to change the finish of the turn piece without touching the lock case.
2) Will the 519F10 thumbturn work on a door thicker or thinner than 1-3/4 inches?
No. The 519F10 packet is built for 1-3/4 inch (44mm) door thickness, which is the standard commercial door. The ML2000 lockset itself is offered in optional thicknesses, but the spindle length in this thumbturn packet is matched to 1-3/4 inches, so on a thicker or thinner leaf you need the packet built for that thickness rather than this one.
3) Where does the thumbturn sit relative to the lever on a Corbin Russwin ML2000 mortise lock?
Center to center, lever to thumbturn is 2-7/16 inches (62mm) on the ML2000. Lever to cylinder is 3-5/8 inches (92mm) on the opposite face. Those two spacings are what your door prep is already cut for, so check the holes in the leaf match before ordering trim, and remember the lock runs a 2-3/4 inch (70mm) backset.
4) I need a deadbolt thumbturn for a commercial mortise lock. Is this the right part or do I need a cylinder?
Depends which face of the door you are working on. The 519F10 thumbturn goes on the secure side and throws the ML2000 one inch stainless steel deadbolt by hand. The other face takes a mortise cylinder, and the ML2000 uses a brass 6-pin L4 keyway cylinder, 0-bitted as standard, and will also accept most other manufacturers' cylinders if you are keying into an existing system. Buying the thumbturn does not get you a cylinder, and buying a cylinder does not get you a turn piece.
5) Will fitting a genuine Corbin Russwin thumbturn keep my fire rated mortise lock compliant?
Using the factory 519F10 packet keeps the ML2000 as it was listed. The ML2000 is UL/cUL listed to UL10C positive pressure and carries a 3 hour fire door rating up to 4 by 10 feet single or 8 by 10 feet pair, and it is ANSI/BHMA A156.13 Series 1000 Grade 1 for both operational and security. Those ratings apply to the assembled lockset with its factory trim, which is exactly why hospitals, schools, and government facilities specify the genuine component rather than a generic turn piece.
6) What finishes does the Corbin Russwin 519F10 thumbturn come in, and will it match my existing lever trim?
Nine finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613E dark oxidized satin bronze equivalent, 619 satin nickel, 625 bright chrome, 626 satin chrome, 630 satin stainless steel, and BSP black suede powder coat. Order the thumbturn in the same BHMA finish code as the lever trim already on the door and it will match. If you are standardizing a building, 626 and 630 are the two that dominate commercial openings.
7) Does replacing the thumbturn on an ML2000 mortise lock require pulling the lock out of the door?
No. The thumbturn is trim, so it comes off the inside face of the door and the ML2000 lock case stays mortised in the edge. Nothing about the latchbolt, deadbolt, or handing changes when you swap it. That is what makes the 519F10 a maintenance part rather than a lockset job.
8) Does the handing of my door matter when ordering the 519F10 thumbturn?
Handing is not a factor for the turn piece. The ML2000 lock case is handed but uses a patented quick reversible latchbolt that can be re-handed without opening the case, and the thumbturn simply drives the deadbolt on the inside face either way. Order by finish and by the 1-3/4 inch door thickness, not by left or right hand.
