Corbin Russwin 488K85 27A1 626 – Frequently Asked Questions

1) What exactly is the Corbin Russwin 488K85 plug, and will it fit my 3000-7 rim cylinder?
The 488K85 is the keyed plug only, a 7-pin Individual X Class plug built for the Corbin Russwin 3000-7 rim cylinder. It drops into that cylinder without modification. It is not a complete cylinder, so if you need a whole rim cylinder assembly rather than the plug, order the cylinder itself.
2) Which keyway do I order on the Corbin Russwin 488K85 plug?
The 488K85 is an A keyway plug, offered in A1 and A2. Match the keyway stamp on the keys already running your Corbin Russwin system, because an A1 plug will not accept an A2 key.
3) Can the 488K85 plug be keyed into an existing Corbin Russwin master key system?
Yes. It is an Individual X Class plug, which places it in Corbin Russwin's keying hierarchy for master key system integration, and the 7-pin chamber count matches 7-pin Corbin Russwin systems. Keyway and pin count both have to match the system you are adding it to.
4) If I need a whole rim cylinder rather than just a replacement plug, what should I order instead of the Corbin Russwin 488K85?
The Corbin Russwin 488K85 27A1 is a 7-pin individual X Class plug for the Corbin Russwin 3000-7 rim cylinder, so it only serves a cylinder that is already in the door. For a complete rim cylinder assembly, the Schlage Commercial 20-021 is a 6-pin rim cylinder supplied with a vertical tailpiece cam and 2 keys, and the Schlage Commercial 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam and 2 keys. Choose the cam orientation that matches the exit device or rim lock being driven.
5) We want to stop pinning plugs and move to interchangeable cores. What is the alternative to the Corbin Russwin 488K85 plug?
The 488K85 27A1 is a pinned individual plug that stays inside the Corbin Russwin 3000-7 rim cylinder, so rekeying means servicing the cylinder. If the goal is core swaps instead, the Schlage Commercial 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam and 2 keys, and the Schlage 20-057-C is an FSIC core in the C keyway with a 643E aged bronze finish. On the BEST side, the 1CDF is a drill resistant patented interchangeable core in 7-pin brass from the 150 series, and the 1C5 is a standard 5-pin core. Moving to cores is a keying-system decision, not a drop-in for a Corbin Russwin A keyway plug.
6) Is a BEST 7-pin core an equivalent to the Corbin Russwin 488K85 7-pin plug since both are 7-pin?
No. Pin count alone does not make them interchangeable. The Corbin Russwin 488K85 27A1 is an individual X Class plug cut for the A keyway and built to seat in the Corbin Russwin 3000-7 rim cylinder. The BEST 1CDF is a 7-pin brass drill resistant patented interchangeable core in the 150 series, which is a figure-eight core format for BEST housings. Matching 7 pins does not match keyway, key control, or the housing the part drops into.
7) The opening is a narrow stile aluminum door with an Adams Rite deadlock, not a rim device. What cylinder should I use instead of the Corbin Russwin 488K85 plug?
The 488K85 27A1 plug only serves a Corbin Russwin 3000-7 rim cylinder, so it has no place in an Adams Rite deadlock prep. For Adams Rite MS1847 deadlock and deadlatch systems, the 4024 cylinder pull mounts with a trim plate and the 4025 is a five pin tumbler cylinder pull with through-screws. For the 5017 wood door deadlock or deadlatch, the 4026 five pin tumbler cylinder pull is the matching part. If the prep calls for a mortise cylinder, the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder rated for a 1/2 inch minimum door thickness.
8) I need a whole rim cylinder, not a plug. What should I look at instead?
For a complete rim cylinder, the Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same with a horizontal cam. If your exit device takes a full size interchangeable core, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. None of these key into a Corbin Russwin A keyway system, so use them where you are rekeying the opening to a Schlage keyway.
9) If I want an interchangeable core setup instead of a keyed plug, what are my options?
A plug like the 488K85 has to be pinned by a locksmith to rekey. If you would rather pull and swap cores in the field, the BEST 1CB 150 Series interchangeable core or the BEST 1CDF drill resistant patented 7-pin brass 150 Series core covers that. Those are BEST keyways, not Corbin Russwin A, so the affected openings get rekeyed to the new system.
10) What is the full model designation I should quote for the Corbin Russwin 488K85?
Quote it as 488K85 27A1: 488K85 is the 7-pin Individual X Class plug, 27 the design, A1 the keyway. Design options run 27, 57, 67 and 77, and keyway A1 or A2, so confirm both when ordering.
11) I need a cylinder for a key-in-knob or key-in-lever lockset, not a rim cylinder plug. What are the options next to the Corbin Russwin 488K85?
The Corbin Russwin 488K85 27A1 is a plug for a rim cylinder and will not serve a knob or lever. For key-in-knob and key-in-lever work, the Kaba Ilco 1539 is a universal key-in-knob and lever cylinder, the 1579 is a knob and lever cylinder for Sargent locks, and the 1599 is a key-in-knob replacement cylinder. For Falcon, the A23161-05 G is a key in lever cylinder for the RU/T series in a 6-pin G keyway, keyed different with 2 cut keys. Identify the lockset brand first, since these are brand-specific fittings.
12) The rim cylinder position is inactive and does not need to key. Is the Corbin Russwin 488K85 still the right part?
No. The 488K85 27A1 is a keyed 7-pin plug in the A keyway, intended to maintain key control in a working Corbin Russwin 3000-7 cylinder. Where the opening only needs the appearance of a cylinder with no keying function, the BEST 12E series dummy rim cylinder measures 1-5/32 inch in diameter and serves that role instead.
13) Our deadbolts and handlesets need retrofit cylinders. Does the Corbin Russwin 488K85 cover those, or is there a different part?
The 488K85 27A1 is a plug for a Corbin Russwin 3000-7 rim cylinder and is not a deadbolt retrofit. For those openings, 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, the 1065244 is a 5-pin lazy motion rim type cylinder supplied with an Emtek tailpiece, and the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. The Kaba Ilco 1549 is a key-in-deadbolt cylinder for deadbolt function. Match the tailpiece and lock brand, since these are not cross-compatible.
14) What is the difference between the Corbin Russwin 488K85 plug and a Detex MC65 mortise cylinder?
They sit in different housings. The 488K85 27A1 is a 7-pin individual X Class plug in the Corbin Russwin A keyway that goes inside a Corbin Russwin 3000-7 rim cylinder. The Detex MC65 is a complete 1-1/8 inch mortise cylinder, 6-pin, in the Schlage C keyway. A mortise cylinder threads into a mortise lock or exit device housing and carries its own cam, so it is not a substitute for a rim cylinder plug or for the rim cylinder itself.
15) Is the 488K85 a genuine Corbin Russwin part suitable for commercial buildings?
It is a manufacturer-authentic Corbin Russwin cylinder component, classed as a commercial replacement part. Facilities standardized on Corbin Russwin keying (schools, hospitals, government buildings, hotels) use it to service existing rim cylinders rather than swapping out hardware.
16) Can I use a lower pin count core in place of the Corbin Russwin 488K85 7-pin plug to simplify the system?
Pin count is a keying-system choice, not a fitment choice. The 488K85 27A1 is a 7-pin plug that integrates into a Corbin Russwin master key hierarchy through its X Class designation and A keyway, and dropping to fewer pins means leaving that system. Among lower pin count parts, the BEST 1C5 is a standard 5-pin cylinder core and the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam. Both require their own housings and keyways rather than seating in a Corbin Russwin 3000-7 cylinder.
17) Is the BEST Peaks 1CB the same kind of part as the Corbin Russwin 488K85?
Both are keying components, but they are not equivalents. The Corbin Russwin 488K85 27A1 is an individual 7-pin X Class plug supplied in the A keyway for the 3000-7 rim cylinder, offered in 606 satin brass and 626 satin chrome. The BEST Peaks 1CB is a 150 series interchangeable core cylinder, which is a removable core rather than a plug pinned inside an existing cylinder body.
