Sargent 130KB 20D – Frequently Asked Questions

1) Will the Sargent 130KB thumbturn fit any Sargent mortise lock, or only the 8200 Series?
The 130KB is built for the Sargent 8200 Series mortise lock and nothing else. It is a factory thumbturn trim part for that platform, so it drops into an 8200 case without modification. If your lock case is another Sargent mortise line, this is the wrong part.
2) My 8200 mortise thumbturn spins loose - do I need a whole new lock?
No. The thumbturn is a separate trim piece on the 8200 platform, so the 130KB replaces just the turn without pulling or replacing the mortise case. That is the point of stocking it as a replacement part rather than a lock assembly.
3) Can a Corbin Russwin 483F80 lever be used to replace a Sargent 130KB thumbturn on an 8200 mortise lock?
No. The Sargent 130KB is a thumbturn lever trim made for the Sargent 8200 Series mortise lock, where it provides keyless locking and unlocking from the inside. The Corbin Russwin 483F80 is an outside lever and spindle for the Corbin Russwin ML2000 Series, sized for a 1-3/4 inch thick door and built around the Corridor/Dormitory function. They serve opposite sides of the door and belong to different mortise platforms, so one does not drop into the other. Stay with the 130KB for an 8200 body and use the 483F80 only on an ML2000 body.
4) What does the 20D suffix mean on a Sargent 130KB thumbturn?
20D is Sargent's Dark Bronze Painted finish, ordered here under the 690 Dark Bronze option. The full model designation is 130KB 20D. If the rest of your 8200 trim on that opening is dark bronze, this matches it; for any other finish you need a different 130KB finish code.
5) What does a thumbturn do on a mortise lock versus a keyed cylinder?
A thumbturn throws and retracts the lock from the inside by hand, no key needed - that is the interior half of a privacy or office-function mortise lock. The keyed cylinder does the same job from the outside. The 130KB is the inside turn piece only; it does not include a cylinder or a lever handle.
6) Does the Sargent 130KB thumbturn carry a Grade 1 rating like the Corbin Russwin 483F80?
Grade ratings apply to complete lockset assemblies rather than to an individual trim piece. The Corbin Russwin 483F80 is published as a Grade 1 outside lever and spindle within the ML2000 Series. The Sargent 130KB is a commercial lock trim component - a thumbturn lever built to factory specification for the Sargent 8200 Series mortise lock - so the grade of the finished opening comes from the 8200 lock body it is installed on, not from the thumbturn itself.
7) Our building is standardizing mortise hardware - how do Sargent 8200 trim parts and Corbin Russwin ML2000 trim parts relate?
They are separate mortise platforms and their trim is not shared. The Sargent 130KB thumbturn lever is made specifically for the Sargent 8200 Series mortise lock in a Dark Bronze Painted 20D finish. The Corbin Russwin 483F80 lever and spindle belongs to the ML2000 Series and is specified for a 1-3/4 inch thick door in the Corridor/Dormitory function. If your doors carry both platforms, keep two trim part lines on the shelf rather than assuming one covers both.
8) Is the Sargent 130KB thumbturn rated for commercial door traffic?
It is a commercial-grade trim component, catalogued for commercial rather than residential use, and Sargent builds it for the same 8200 mortise locks that go on office, school, healthcare, retail and government openings.
9) I'm standardizing dark bronze hardware across a building - will this 130KB match my other Sargent trim?
It will if that trim is specified 20D. Sargent uses the same Dark Bronze Painted code across the line, so a 130KB 20D turn sits alongside 20D levers, roses and escutcheons on the same opening without a color mismatch.
