Corbin Russwin 354F19-8 – Frequently Asked Questions

1) What exactly comes in the Corbin Russwin 354F19-8 part?
Two pieces: a thumbturn disk and an A64 cam. The 354F19-8 is a Corbin Russwin cylinder repair part for Master Ring cylinder assemblies, so you get both drive-train components rather than a complete cylinder. If your cylinder housing and plug are fine and only the turn disk or cam is worn, this is the part that repairs it.
2) Will the 354F19-8 fit any Corbin Russwin cylinder, or only certain ones?
It is built for Corbin Russwin Master Ring cylinder assemblies, and the cam supplied is the A64. Cams are not universal within a brand, so if the lock you are servicing calls for a different cam designation, this kit is not the match. Confirm the cylinder is a Master Ring type and that the lock takes an A64 cam before you order.
3) If the Corbin Russwin master ring cylinder is too far gone to rebuild, what complete mortise cylinder can go in instead?
The 354F19-8 is a repair part - a thumbturn disk packaged with an A64 cam for rebuilding the drive train of a Corbin Russwin master ring cylinder rather than replacing the cylinder body. When the cylinder itself is scrap, a complete mortise cylinder is the path: the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder in the 4036 Series with a 1/2 inch minimum door thickness, and the Detex MC65 is a 1-1/8 inch six-pin commercial mortise cylinder cut to the Schlage C keyway. Both are whole cylinders, so the existing key system and cam requirement of the opening need to be matched before ordering.
4) The opening is an exit device with a rim cylinder, not a master ring mortise cylinder - what do I order?
The 354F19-8 thumbturn disk and A64 cam serve Corbin Russwin master ring cylinder assemblies and will not fit a rim application. For rim cylinders, Schlage's commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam; both ship with two keys. Cam orientation is what the device dictates, so confirm vertical versus horizontal against the exit device before ordering.
5) Do I need a new cylinder or can I just replace the thumbturn disk and cam?
If the failure is in the turn disk or the cam, the 354F19-8 lets you rebuild that part of the cylinder instead of pulling and rekeying a whole new one, which also keeps the existing keying intact. If the plug, pins or housing are damaged, or the keyway is wrong for your system, you need a full cylinder rather than this repair kit.
6) Can I use a Schlage or BEST cylinder part to repair a Corbin Russwin Master Ring cylinder?
No. Cylinder internals are brand and platform specific. Parts like the Schlage 20-021 and 20-022 rim cylinders or the BEST 1C Series 5-pin core are complete cylinders or cores for their own systems, not components that drop into a Corbin Russwin Master Ring housing. For that repair you want the Corbin Russwin 354F19-8 thumbturn disk and A64 cam.
7) I need to replace the whole cylinder instead of rebuilding it. What are my options?
For a full replacement rather than a repair, look at complete cylinders instead of the 354F19-8 kit. Examples ZenSupply carries include the Schlage 20-057 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam, the Detex MC65 1-1/8 inch 6-pin mortise cylinder in Schlage C keyway, and the Adams Rite 4036 Grade 1 five-pin mortise cylinder. Those are separate keying platforms, so a swap means rekeying to match your system.
8) How is the 354F19-8 ordered, and are there finish or keyway choices to pick?
It is ordered as the single part number 354F19-8, with no finish, keyway or handing options to select. The cam designation is fixed at A64, so the only thing you need to verify is that your Master Ring cylinder assembly takes that cam.
9) Is a BEST interchangeable core an equivalent to the Corbin Russwin 354F19-8?
No. The 354F19-8 is a replacement internal part - a thumbturn disk and A64 cam for a Corbin Russwin master ring cylinder assembly. A BEST core such as the 1C Series standard 5-pin cylinder core or the 1CB 150 Series interchangeable core is a keyed core that drops into a figure-eight housing; it does not rebuild a master ring cylinder. Interchangeable core is a different servicing approach: cores are swapped out whole rather than repaired at the cam.
10) Our facility wants to move off repairing master ring cylinders and standardize on swappable cores - what should we look at?
The Corbin Russwin 354F19-8 supports the existing approach, letting a technician restore a master ring cylinder's drive train without replacing the whole cylinder. Facilities that would rather swap a core in seconds move to an interchangeable core platform: the BEST 1CB 150 Series interchangeable core, the drill-resistant patented BEST 1CDF 7-pin brass 150 Series core, or a Schlage full size interchangeable core setup such as the 20-057 six-pin FSIC rim cylinder with convertible tailpiece cam. That change is a rekey of the system, not a part-for-part swap, so plan it across the whole door group.
11) Will the Corbin Russwin 354F19-8 work on an aluminum storefront deadlock?
No. It is a commercial cylinder repair part built around the Corbin Russwin master ring cylinder. Narrow-stile storefront deadlocks are served by dedicated cylinder pulls: the Adams Rite 4024 cylinder pull with trim plate mounting and the 4025 five-pin cylinder pull with through-screws are both for the Adams Rite MS1847 deadlock/deadlatch, and the 4026 five-pin cylinder pull is for the 5017 wood door deadlock/deadlatch. Match the pull to the deadlock family already in the door.
12) I need a replacement cylinder for a key-in-knob or key-in-lever lock, not a cam and disk kit - what are the options?
The Corbin Russwin 354F19-8 supplies the thumbturn disk and A64 cam for a master ring cylinder and does not serve knob or lever cylinders. Kaba Ilco covers that with the 1539 Series key-in-knob/lever universal cylinder, the 1579 Series knob and lever cylinder built for Sargent locks, and the 1599 key-in-knob replacement cylinder; the 1549 Series is a key-in-deadbolt cylinder. Falcon's A23161-05 G is a key-in-lever cylinder with a 6-pin G keyway, keyed different with two cut keys. Identify the lock brand and keyway first, since these are brand-specific fits.
13) We use Schlage C keyway across the building - what cylinder matches that instead of the Corbin Russwin part?
The Corbin Russwin 354F19-8 is a repair component for Corbin Russwin master ring cylinders and does not change or match a keyway. For a Schlage C keyway system, the Schlage 20-057-C is a full size interchangeable core cylinder in C keyway with a 643E aged bronze finish, and the Detex MC65 is a 1-1/8 inch 6-pin commercial grade mortise cylinder cut to the Schlage C keyway. Choose between them on whether the opening takes a mortise cylinder or an FSIC housing.
14) Is the 354F19-8 a commercial-duty part or for residential locks?
Commercial. It belongs to the Corbin Russwin commercial mechanical lock cylinder line and is intended for institutional door hardware service work, the sort of high-use openings found in schools, hospitals, offices and municipal buildings.
15) Is the 354F19-8 a genuine Corbin Russwin part or an aftermarket copy?
Genuine Corbin Russwin, supplied as an OEM cylinder replacement part built to the manufacturer's own tolerances so it seats in a Master Ring cylinder without modification. For facilities standardized on Corbin Russwin cylinders, that keeps the repaired lock matched to the rest of the hardware.
16) Is there a higher-security cylinder option if we are already servicing these cylinders regularly?
The 354F19-8 restores a Corbin Russwin master ring cylinder to original function and keeps the existing key system intact. If the goal is to raise the security level rather than restore it, the BEST 1CDF is a drill-resistant patented interchangeable core in 7-pin brass, 150 Series, and Medeco offers retrofit cylinders such as the 1065140 5-pin cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, and the 1075127 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. Those are new key systems, so they get planned by door group rather than installed one at a time.
17) What if the door only needs a non-keyed cylinder for appearance or pull function?
The Corbin Russwin 354F19-8 is a functional repair part - the thumbturn disk and A64 cam that drive a master ring cylinder. Where an opening needs a cylinder that fills the hole without operating anything, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter serves that role. Emtek's CY4 cylinder is another single cylinder component sold individually. Confirm whether the opening actually needs keyed function before substituting a dummy.
18) Can a Medeco lazy motion rim cylinder be used in place of the Corbin Russwin master ring cylinder parts?
No, they solve different problems. The 354F19-8 is a drive train component set - thumbturn disk plus A64 cam - for a Corbin Russwin master ring cylinder. The Medeco 1012040 is a complete 6-pin lazy motion rim cylinder made for Kwikset single cylinder deadbolts, and the 1065244 is a 5-pin lazy motion rim cylinder supplied with an Emtek tailpiece. Those are keyed rim cylinders matched to specific residential-style deadbolt and handleset platforms, not internal parts for a commercial master ring mortise cylinder.
