Corbin Russwin Cylinder Parts

Corbin Russwin 628F835 – Frequently Asked Questions

1) What exactly is the Corbin Russwin 628F835 part, and what does it do?
It's a throw member component for Corbin Russwin LFIC (less full interchangeable core) cylinders. The throw member is the piece that transfers key rotation from the core into the lock mechanism, so replacing it restores cylinder actuation without swapping the whole housing. It is a genuine Corbin Russwin service part, not a complete keyed cylinder, so it arrives with no core and no keys.
2) Which Corbin Russwin cylinder assemblies does the 628F835 throw member fit?
It is made for Corbin Russwin cylinder assemblies 1030-112 and 1037-112. Those two are the stated applications, so if the cylinder on your door is a different Corbin Russwin assembly number, verify the assembly first rather than assuming this throw member drops in.
3) Does the 628F835 come with a core or keys?
No core and no keys. LFIC means the assembly is supplied less the core, so the interchangeable core and its cut keys are ordered separately to whatever keyway and keying system the building already uses. If you need a complete keyed cylinder instead of a service part, a factory-keyed unit like the Falcon A23161-05 G key-in-lever cylinder ships keyed different with two cut keys.
4) Can a BEST interchangeable core be used instead of the Corbin Russwin 628F835 throw members?
No. The Corbin Russwin 628F835 is a replacement throw member part for Corbin Russwin LFIC cylinder assemblies 1030-112 and 1037-112, not a keyed core. A BEST 1CB 150 Series interchangeable core cylinder or a BEST 1C Series standard 5-pin core is the keyed core that drops into a core housing. If the throw members inside the Corbin Russwin housing are worn or missing, a core will not replace them; if you need the keyed element, the core is the item.
5) If I am replacing the whole cylinder rather than repairing it, what full cylinders are available instead?
The 628F835 is a component-level repair part for Corbin Russwin LFIC cylinder assemblies. If you would rather change out a complete cylinder, full units include the Adams Rite 4036 mortise cylinder with five-pin security, a Grade 1 cylinder for doors 1/2 inch minimum thickness, and the Detex MC65 mortise cylinder with a Schlage C keyway in 1-1/8 inch, 6-pin commercial grade. Those are complete keyed cylinders and will change the keying of the opening, where the 628F835 restores the existing assembly.
6) Will the 628F835 work with a full size interchangeable core cylinder?
No. This throw member is built for LFIC cylinders, meaning the housing is supplied less the core and takes a Corbin Russwin small-format interchangeable core. It is not a part for a full size interchangeable core (FSIC) housing. If you're working on an FSIC opening, you'd be looking at a different platform, such as a Schlage 20-057 FSIC rim cylinder or the 20-057-C FSIC core.
7) My Corbin Russwin key turns but the lock doesn't retract, is a throw member the fix?
That symptom points at the throw member. The core is rotating but the motion isn't reaching the lock, and the throw member is the mechanical link that makes that engagement. The 628F835 restores throw member function inside a compatible 1030-112 or 1037-112 LFIC assembly. If the housing itself is damaged or the wrong assembly number, replace the cylinder rather than the throw member.
8) Can I use a Kaba Ilco or BEST cylinder instead of repairing the Corbin Russwin assembly?
Only if you're replacing the whole cylinder, not repairing it. The 628F835 is a Corbin Russwin internal part and won't fit another brand's housing. If you'd rather swap the cylinder out, Kaba Ilco offers universal replacement cylinders such as the 1539 Series key-in-knob/lever and the 1599 key-in-knob, and BEST covers interchangeable core work with the 1C Series 5-pin core and the 1CB 150 Series interchangeable core. Keying to the existing system is the thing to settle before you change platforms.
9) Is the 628F835 a mortise cylinder or a rim cylinder?
Neither. It is a component that goes inside a Corbin Russwin LFIC cylinder assembly, not a cylinder you install in a door on its own. For a complete mortise cylinder, the Detex MC65 is a 1-1/8 inch 6-pin with a Schlage C keyway; for a rim cylinder, the Schlage 20-021 uses a vertical tailpiece cam and the 20-022 a horizontal cam.
10) I need an interchangeable core cylinder for a rim device, not a Corbin Russwin repair part. What should I look at?
The Corbin Russwin 628F835 is throw members for Corbin Russwin LFIC assemblies 1030-112 and 1037-112 and does not serve a rim device on its own. For a rim application with an interchangeable core, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam supplied with 2 keys, and the Schlage 20-057-C is a full size interchangeable core cylinder in the C keyway, 643E aged bronze. Note those are full size IC, where the Corbin Russwin part belongs to a less-full-interchangeable-core assembly.
11) What is the difference between the 628F835 and a key-in-knob replacement cylinder like the Kaba Ilco 1599?
The Corbin Russwin 628F835 is an internal throw member part that restores mechanical engagement inside Corbin Russwin LFIC cylinder assemblies 1030-112 and 1037-112. The Kaba Ilco 1599 is a key-in-knob replacement cylinder and the Kaba Ilco 1539 is a key-in-knob/lever universal cylinder, both complete keyed cylinders that install into a knob or lever chassis. If the lock is a Corbin Russwin LFIC cylinder assembly, the Ilco units are for a different lock format, not a substitute.
12) We are standardizing cylinders across a facility rather than repairing Corbin Russwin assemblies one at a time. What is a common platform?
The 628F835 is a Corbin Russwin specific repair part, so it keeps each opening on its existing Corbin Russwin LFIC assembly. For facility-wide standardization on an interchangeable core platform, the BEST 1CB 150 Series interchangeable core and the BEST 1CDF drill resistant patented 7-pin brass 150 Series core are both 150 Series cores, the 1CDF adding drill resistance and patented key control. Standardizing means changing cylinder housings at the openings, not just swapping the internal parts.
13) Would an Adams Rite cylinder pull work in place of this Corbin Russwin part on an aluminum storefront?
No, they solve different problems. The Corbin Russwin 628F835 supplies LFIC throw members inside Corbin Russwin cylinder assemblies 1030-112 and 1037-112. The Adams Rite 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws are both designed for use with the Adams Rite MS1847 deadlock/deadlatch, and the 4026 five pin tumbler cylinder pull is for the Adams Rite 5017 wood door deadlock/deadlatch. Those are pull assemblies tied to specific Adams Rite locks, not Corbin Russwin repair components.
14) Is there a rim cylinder I can order if the Corbin Russwin assembly is being replaced with an exit device trim?
For a rim application, the Schlage 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 6-pin rim cylinder with a horizontal tailpiece cam. Cam orientation is the deciding detail, so confirm which the device calls for. The Corbin Russwin 628F835 remains the part to order when you are keeping the existing Corbin Russwin LFIC cylinder assembly and only restoring the throw members.
15) The failure is in a deadbolt cylinder, not an LFIC assembly. What should I order?
The Corbin Russwin 628F835 supplies throw members for Corbin Russwin LFIC cylinder assemblies 1030-112 and 1037-112, so it is not the answer for a deadbolt cylinder. The Kaba Ilco 1549 Series is a key-in-deadbolt cylinder with a deadbolt function, and the Kaba Ilco 1539 Series universal cylinder also carries a deadbolt function. Confirm the host lock body before ordering, since these are complete cylinders rather than internal parts.
16) Is this a commercial part or is it suitable for residential locks?
Commercial. The 628F835 is a commercial-grade Corbin Russwin cylinder part, intended for office buildings, schools, healthcare, government, retail, industrial and multi-tenant residential openings serviced by qualified locksmiths. For residential handleset and deadbolt retrofits you'd be looking at something like the Medeco 1075127 lazy motion rim cylinder for handlesets and deadbolts instead.
17) Can maintenance staff install the 628F835 or does it need a locksmith?
Plan on a locksmith or a hardware tech. Fitting a throw member means opening up the cylinder assembly and setting the engagement correctly, and the part is specified for qualified locksmiths and door hardware professionals servicing Corbin Russwin cylinder systems. For a property manager standardizing across a lot of doors, swapping to a complete interchangeable core cylinder is usually the simpler in-house path.
18) Is a dummy cylinder an acceptable stand-in for the 628F835 on a non-keyed opening?
Only if the opening truly needs no key function. The BEST 12E Series dummy rim cylinder has a 1-5/32 inch diameter and fills a rim prep without operating anything. The Corbin Russwin 628F835 is a working throw member component for Corbin Russwin LFIC cylinder assemblies 1030-112 and 1037-112, so it is the part when the cylinder must actually throw the lock. A dummy is a trim filler, not a repair for a functioning assembly.
19) Does a Sargent or Falcon cylinder cross over to the Corbin Russwin 628F835?
No. The Kaba Ilco 1579 is a knob and lever cylinder made 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. Each is built around its own manufacturer's lock chassis. The Corbin Russwin 628F835 is a genuine Corbin Russwin component for LFIC cylinder assemblies 1030-112 and 1037-112 and is the correct order for those assemblies.
20) We use Medeco keyways in the building. Is there a Medeco option instead of this Corbin Russwin part?
Medeco offerings in this space are complete cylinders rather than internal components. The Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, and the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. Each targets a named host lock. The Corbin Russwin 628F835 is a commercial replacement part for Corbin Russwin LFIC cylinder assemblies and is not keyway-driven.
21) Is the 628F835 a residential-grade part, or should I look elsewhere for a house door?
The Corbin Russwin 628F835 is specified for commercial use as a replacement part for Corbin Russwin LFIC cylinder assemblies 1030-112 and 1037-112. For residential handleset and deadbolt work, the Emtek CY4 cylinder is sold each, and the Medeco 1065244 is a 5-pin rim lazy motion rim type cylinder supplied with an Emtek tailpiece. Those match residential lock bodies rather than commercial LFIC assemblies.
