Corbin Russwin 488F08-8 – Frequently Asked Questions

1) What exactly is the Corbin Russwin 488F08-8, a cylinder or just the screw?
It's the set screw packet only, not a cylinder. The 488F08-8 is a genuine OEM Corbin Russwin replacement part that holds a mortise cylinder in position inside the lock body. If you need the cylinder itself, this is not the part to order.
2) My Corbin Russwin mortise cylinder keeps turning loose in the lock body. Is this the part I need?
That symptom is usually a missing or stripped cylinder set screw, and the 488F08-8 packet is the OEM replacement for that screw in compatible Corbin Russwin mortise cylinder assemblies. It restores retention without replacing the lock or the cylinder.
3) Will the 488F08-8 set screw work in a Schlage or Sargent mortise lock?
It's specified for compatible Corbin Russwin mortise cylinder assemblies only. For other brands, use that manufacturer's own cylinder retention screw. Cross-brand fit for this packet isn't something to assume, since set screw thread and length vary by lock body.
4) Is the Corbin Russwin 488F08-8 a replacement cylinder, or just the hardware that holds one in place?
The 488F08-8 is a set screw packet only - a replacement part that retains and positions a Corbin Russwin mortise cylinder inside the lock body. It contains no plug, pins, or keys. If the cylinder itself needs replacing rather than the retaining hardware, a complete mortise cylinder is the item to order instead, such as the Detex MC65 mortise cylinder with Schlage C keyway in 1-1/8 inch 6-pin form, or the Adams Rite 4036 five-pin mortise cylinder.
5) My opening uses a rim device, not a mortise lock - what cylinder parts apply there instead of the 488F08-8?
The 488F08-8 is specific to Corbin Russwin mortise cylinder assemblies, where a set screw holds the threaded cylinder in the lock body. Rim devices retain the cylinder with a back plate and screws instead, so for a rim opening the item to specify is a rim cylinder: the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and two keys, the 20-022 is the same in horizontal tailpiece cam form, and the BEST 12E Series dummy rim cylinder has a 1-5/32 inch diameter.
6) For an aluminum storefront with an Adams Rite MS1847 deadlock, is the 488F08-8 the retaining part I need?
No. The 488F08-8 retains cylinders in Corbin Russwin mortise cylinder assemblies and is a commercial-grade Corbin Russwin cylinder part. Adams Rite MS1847 openings take their own cylinder trim: the 4024 cylinder pull mounts with a trim plate for MS1847 deadlock and deadlatch systems, and the 4025 is a five pin tumbler cylinder pull using through-screws for the MS1847. For a wood door deadlock, the 4026 five pin tumbler cylinder pull is built for the Adams Rite 5017 wood door deadlock and deadlatch.
7) Can a locksmith fix a loose Corbin Russwin cylinder in the field with this, or does the whole lock have to come off?
Field serviceable. The packet lets a technician restore the mortise cylinder assembly rather than replacing the hardware, so it's a screw swap at the door rather than a lock change.
8) We are moving to interchangeable cores for keying control - does the 488F08-8 factor into that?
No. The 488F08-8 is a Corbin Russwin set screw packet for retaining a mortise cylinder and has no bearing on keying. Facilities standardizing on removable cores specify the core and housing instead: the BEST 1CB is a 150 Series interchangeable core cylinder, the BEST 1CDF is a drill-resistant patented interchangeable core 7-pin brass 150 Series core, the BEST 1C is a standard 5-pin core, and on the Schlage side the 20-057 is a 6-pin FSIC rim cylinder with convertible tailpiece cam while the 20-057-C is a full size interchangeable core in C keyway, 643E aged bronze.
9) Will the 488F08-8 work on a knob or lever lock cylinder replacement?
The 488F08-8 is made for Corbin Russwin mortise cylinder assemblies, where the cylinder threads into the lock case and a set screw holds it. Key-in-knob and key-in-lever cylinders are retained differently and are ordered as complete cylinders: the Kaba Ilco 1539 Series is a key-in-knob and lever universal cylinder, the 1579 is a knob and lever cylinder for Sargent, the 1599 is a key-in-knob replacement cylinder, and the Falcon A23161-05 G is a key-in-lever cylinder with a 6-pin G keyway, keyed different with two cut keys.
10) We are servicing residential deadbolts and handlesets - is there an equivalent small part to the 488F08-8, or do we replace the whole cylinder?
The 488F08-8 covers only the set screw retention on Corbin Russwin mortise cylinders, a commercial line. Residential deadbolt and handleset service is normally done by swapping the cylinder outright: the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece, and the 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders.
11) Is the Corbin Russwin 488F08-8 interchangeable with set screws from other lock brands?
The 488F08-8 is a genuine OEM Corbin Russwin part machined to Corbin Russwin specifications so it seats correctly against the cylinder in a Corbin Russwin lock body. Other brands' cylinders are supplied as complete assemblies with their own retention arrangements - for example the Adams Rite 4036 mortise cylinder is a Grade 1 cylinder in the 4036 Series with a 1/2 inch minimum door thickness, and the Emtek CY4 cylinder is sold each as a part. Specify the 488F08-8 where the installed hardware is Corbin Russwin.
12) Is this a commercial-duty part or a residential one?
Commercial. The 488F08-8 packet is built to Corbin Russwin's commercial door hardware standards and is used in offices, schools, hospitals, government buildings, retail, warehouses, and multi-tenant residential properties.
13) Do I have to use the genuine Corbin Russwin screw, or will a generic set screw do?
The 488F08-8 is made to OEM specification so it seats correctly against the cylinder without binding or backing out. A generic screw of the wrong length or thread can bottom out on the cylinder shell or fail to grip, which is why the OEM packet is specified for Corbin Russwin mortise cylinder installations.
14) I manage a building standardized on Corbin Russwin mortise locks. Is this worth stocking for maintenance?
Yes, it's a common consumable on a Corbin Russwin mortise fleet. Cylinder set screws get stripped or lost during rekeying and core swaps, and having the 488F08-8 packet on the shelf keeps a door from sitting with a loose cylinder while you wait on a part.
