Corbin Russwin 310F48-8 – Frequently Asked Questions

1) What exactly is the Corbin Russwin 310F48-8 part?
It is a thumbturn disk with an A02 cam, a genuine OEM cylinder component from Corbin Russwin's cylinder parts line. It is the turn piece and cam, not a complete keyed cylinder, so it goes into a compatible Corbin Russwin cylinder assembly to restore thumbturn operation when the original is worn or damaged.
2) Will a Corbin Russwin 310F48-8 thumbturn work in any brand of mortise lock cylinder?
No. The A02 cam profile is matched to Corbin Russwin cylinder tailpieces and lock bodies, so it is intended for compatible Corbin Russwin cylinder assemblies. Cam profiles are what drive the lock, and a mismatched cam will not throw the bolt correctly even if the threads look the same. For other brands, use that brand's own cylinder, such as a Schlage 20-021 rim cylinder or a Detex MC65 mortise cylinder.
3) I need to replace a worn thumbturn on a Corbin Russwin cylinder without pulling the whole lock. Is this the right part?
That is exactly what the 310F48-8 is for. It is a drop-in replacement thumbturn disk for compatible Corbin Russwin cylinder assemblies, so a locksmith or maintenance tech can service the turn piece in the field instead of replacing the full cylinder. Confirm your existing cylinder uses the A02 cam before you order.
4) Is the Corbin Russwin 310F48-8 thumbturn disk a complete cylinder, or do I need a full cylinder like the Schlage 20-021?
The 310F48-8 is a thumbturn disk with an A02 cam - a replacement component that restores thumbturn operation inside a compatible Corbin Russwin cylinder assembly, not a keyed cylinder on its own. If the job needs a complete keyed unit rather than a part, the Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam supplied with 2 keys, and the Schlage 20-022 is the same rim cylinder with a horizontal tailpiece cam. Order the 310F48-8 only when the existing Corbin Russwin cylinder body is sound and the thumbturn component is worn or damaged.
5) Will the Corbin Russwin 310F48-8 work in a Kaba Ilco or Falcon cylinder?
No. The 310F48-8 is a genuine Corbin Russwin part with an A02 cam profile matched to the corresponding Corbin Russwin tailpiece and lock body, so it is a drop-in only for compatible Corbin Russwin cylinder assemblies. For other lock lines you replace the whole cylinder instead: the Kaba Ilco 1599 is a key-in-knob replacement cylinder, the 1579 is a knob and lever cylinder for Sargent, and the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T Series with a 6-pin G keyway, keyed different with 2 cut keys.
6) For a deadbolt or exit-device opening where a thumbturn disk repair does not apply, what should I order instead?
The Corbin Russwin 310F48-8 is a commercial cylinder replacement part, so it only serves an existing Corbin Russwin thumbturn cylinder. For a deadbolt cylinder, the Kaba Ilco 1549 is a key-in-deadbolt cylinder and the Kaba Ilco 1539 is a key-in-knob/lever universal cylinder, both listed for deadbolt function. For narrow-stile and storefront deadlocks, Adams Rite offers the 4036 mortise cylinder, a Grade 1 five-pin unit in the 4036 Series with a 1/2 inch minimum door thickness, plus the 4025 five-pin cylinder pull with through-screws for the MS1847 deadlock and the 4026 five-pin cylinder pull for the 5017 wood door deadlock.
7) Does the 310F48-8 thumbturn take a key?
No. The thumbturn disk is for keyless manual operation from the inside. If you need a keyed function on that side of the door, you want a keyed cylinder rather than this turn piece.
8) If I am standardizing thumbturn cylinders across a building, can I substitute a different brand's cylinder instead?
You can, but not with this part. The 310F48-8 is a Corbin Russwin service component, so it only keeps existing Corbin Russwin cylinders running. If the goal is one platform across a facility, look at a keyed system instead, such as BEST interchangeable core cylinders in the 1C or 1CB series, or Schlage full size interchangeable core cylinders like the 20-057. Those change the cylinder itself rather than servicing what is already there.
9) We want keyless interior operation but also key control from the outside - what pairs with a Corbin Russwin thumbturn disk repair?
The Corbin Russwin 310F48-8 handles the interior side: it is a thumbturn disk giving keyless manual operation where no key is wanted inside. For the outside half on a keyed system, interchangeable-core options include the BEST 1CB, a 150 Series interchangeable core cylinder, and the BEST 1CDF, a drill-resistant patented 7-pin brass interchangeable core in the 150 Series. On the Schlage side, the 20-057 is a 6-pin full-size interchangeable core rim cylinder with a convertible tailpiece cam.
10) Is there a simpler option than repairing a Corbin Russwin thumbturn cylinder with the 310F48-8?
Repairing with the 310F48-8 keeps the installed Corbin Russwin cylinder body and keying in place, since it is a drop-in replacement engineered to factory specification. The simpler alternative is a whole-cylinder swap: the BEST 1C5 is a standard 5-pin cylinder core, and the Schlage 20-057-C is a full-size interchangeable core in the C keyway with a 643E aged bronze finish. Those change the cylinder rather than service it, so on a facility already standardized on Corbin Russwin keying the part-level repair holds the existing system.
11) On an Adams Rite MS1847 storefront deadlock, can the Corbin Russwin 310F48-8 be used?
No. The 310F48-8 is a Corbin Russwin cylinder part built around the A02 cam for Corbin Russwin assemblies. An MS1847 opening takes hardware made for it, such as the Adams Rite 4024 cylinder pull with trim plate mounting or the 4025 five pin tumbler cylinder pull with through-screws, both listed for use with the MS1847 deadlock/deadlatch.
12) Is the 310F48-8 rated for commercial door hardware use?
Yes, it is a commercial-grade part intended for commercial mechanical lock applications, the kind found in offices, schools, hospitals, government buildings, retail, warehouses, and multi-tenant residential.
13) Is there more than one version of the 310F48-8 to choose from?
No options to specify. The 310F48-8 is sold as a single configuration, the thumbturn disk with the A02 cam.
14) Do any comparable cylinders use a lazy-motion cam instead of the A02 cam on the Corbin Russwin 310F48-8?
Yes. The 310F48-8 carries an A02 cam profile matched to Corbin Russwin cylinder assemblies. Lazy-motion designs are a different drive arrangement: the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single-cylinder deadbolts, the 1065244 is a 5-pin rim lazy motion cylinder supplied with an Emtek tailpiece, the 1075127 is a 5-pin rim lazy motion single cylinder for handlesets and deadbolts, and the 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders. None of those interchange with a Corbin Russwin A02 cam part.
