Corbin Russwin 488K85 27 626 – Frequently Asked Questions

1) What exactly is the Corbin Russwin 488K85 part, and does it include the whole cylinder?
The 488K85 is a plug only, not a complete cylinder. It's the 7-pin X Class individual plug that goes into a Corbin Russwin 3000-7 rim cylinder, so a locksmith can rebuild a worn or damaged cylinder instead of replacing the housing. If you need a complete rim cylinder rather than a plug, look at a full rim cylinder assembly such as the Schlage Commercial 20-021 or 20-022 6-pin rim cylinder instead.
2) Which keyways can I order the Corbin Russwin 488K85 7-pin plug in?
Five keyways are offered: 27, 67, 77, 97 and 99. Pick the one that matches the existing Corbin Russwin system on the building, otherwise the rebuilt cylinder won't take your current keys or fall under your master key.
3) Will a 6-pin Corbin Russwin cylinder accept this plug?
No. The 488K85 is built as a 7-pin plug for the 3000-7 rim cylinder platform. A 6-pin housing has different chamber count and pinning, so you need the plug matched to your cylinder's pin count.
4) Does buying this plug keep my building on the same master key system?
Yes, provided you order the keyway already in use. The plug is an OEM Corbin Russwin part with a dedicated keyway profile, so once pinned to your existing key bitting it stays inside the master key system. The plug ships as a component to be pinned, not as a keyed-alike finished cylinder.
5) If I need a complete rim cylinder rather than just a plug, what should I order instead of the Corbin Russwin 488K85?
The 488K85 is a 7-pin individual X Class plug for the 3000-7 rim cylinder, so it only restores the plug inside a housing you already have. For a complete rim cylinder, 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 6-pin rim cylinder with a horizontal tailpiece cam and 2 keys. Pick the cam orientation that matches the exit device or rim lock being driven.
6) Is a Schlage 20-057 FSIC rim cylinder a substitute for the Corbin Russwin 488K85 plug?
They serve different service models. The 488K85 is an individual replacement plug for the Corbin Russwin 3000-7 rim cylinder, so the housing stays in the door and the plug is swapped. The Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam and 2 keys, where the interchangeable core is pulled with a control key; the 20-057-C is the FSIC core itself in C keyway and 643E Aged Bronze. If your openings are already on the Corbin Russwin 3000-7 platform, the 488K85 keeps that keying system; the Schlage parts move the opening to an FSIC system.
7) The opening is a mortise prep, not rim. What should I use instead of the Corbin Russwin 488K85?
The 488K85 plug fits the Corbin Russwin 3000-7 rim cylinder only. For a mortise prep, the Adams Rite 4036 is a five-pin mortise cylinder, Grade 1, 4036 Series, with a 1/2 inch minimum door thickness, and the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in Schlage C keyway. Confirm cylinder length and cam against the mortise lock body before ordering.
8) What finishes does the 488K85 plug come in, and does the plug finish have to match my cylinder housing?
Two finishes: 606 satin brass and 626 satin chrome. Both are offered in all five keyways. Since the plug face is the visible part once installed, match it to the existing cylinder ring and trim so a rebuilt cylinder doesn't stand out against the other doors.
9) What's the alternative if I want interchangeable cores instead of rebuilding fixed plugs?
Rebuilding a 3000-7 with a 488K85 plug means bench work by a locksmith each time. If you'd rather swap keying at the door without disassembly, move to an interchangeable core platform: the BEST 1CB 150 Series interchangeable core, the 7-pin BEST 1CDF drill-resistant core, or a full-size interchangeable core rim cylinder like the Schlage 20-057 with its convertible tailpiece cam. That's usually the better call for a facility standardizing across many openings.
10) Can I use the 488K85 to replace a plug in a mortise cylinder?
No. It is specified for the 3000-7 rim cylinder. Mortise cylinders are a different body with threaded housings and cam drive, so for a mortise application choose a mortise cylinder such as the Detex MC65 1-1/8 inch 6-pin or the Adams Rite 4036.
11) Do I get keys or pins with the 488K85 plug?
Treat it as a bare replacement plug. It's catalogued as an individual X Class plug for field servicing, meaning the technician supplies the pinning and cuts keys to the existing system. If you need a cylinder that arrives keyed with cut keys, a complete unit like the Schlage 20-022 rim cylinder ships with 2 keys.
12) What is the closest interchangeable-core alternative if I want a 7-pin core instead of the Corbin Russwin 488K85 plug?
The 488K85 is a 7-pin plug tied to the Corbin Russwin 3000-7 rim cylinder. If you would rather standardize on removable cores, the BEST 1CDF is a drill resistant patented interchangeable core in 7-pin brass, 150 Series, and the BEST 1C is a standard 5-pin cylinder core if 7-pin key control is not required. The BEST Peaks 1CB is a 150 Series interchangeable core cylinder in the same family.
13) Can the Corbin Russwin 488K85 be used in a key-in-knob or lever lock?
No. The 488K85 is a plug for the Corbin Russwin 3000-7 rim cylinder platform. For knob and lever cylinders, the Kaba Ilco 1539 is a universal key-in-knob and lever 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 for the RU/T series with a 6-pin G keyway, keyed different with 2 cut keys. For deadbolt preps the Kaba Ilco 1549 is a key-in-deadbolt cylinder.
14) For a residential handleset or deadbolt retrofit, is the Corbin Russwin 488K85 the right part?
The 488K85 is a commercial Corbin Russwin plug for the 3000-7 rim cylinder. For handleset and deadbolt retrofits, Medeco offers rim-type options: the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065244 is a 5-pin lazy motion rim cylinder with an Emtek tailpiece, and the 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder.
15) I only need to fill a rim cylinder hole with no key function. Is the 488K85 what I want?
No, the 488K85 is a keyed 7-pin plug that restores operating function in a Corbin Russwin 3000-7 rim cylinder. If the hole needs to be covered without key operation, the BEST 12E Series dummy rim cylinder has a 1-5/32 inch diameter and provides the rim cylinder appearance without a working mechanism.
16) What should I use on an Adams Rite MS1847 deadlock instead of the Corbin Russwin 488K85?
The 488K85 plug is matched to the Corbin Russwin 3000-7 rim cylinder and is not a fit for Adams Rite narrow stile hardware. The Adams Rite 4024 cylinder pull mounts with a trim plate and is designed for the MS1847 deadlock and deadlatch, and the 4025 is a five pin tumbler cylinder pull with through-screws for the same MS1847. For wood door applications, the 4026 five pin tumbler cylinder pull is designed for the Adams Rite 5017 wood door deadlock and deadlatch.
17) Is this a residential-duty part or rated for commercial traffic?
It is a commercial part, built to Corbin Russwin's commercial cylinder standards, and it's used in offices, schools, healthcare, government buildings, multi-tenant residential, retail and warehouse work.
18) How do finish choices on the Corbin Russwin 488K85 compare with the Schlage FSIC core?
The 488K85 plug is offered in 606 Satin Brass and 626 Satin Chrome, each available in 27, 67, 77, 97 and 99 keyways. The Schlage 20-057-C full size interchangeable core is supplied in C keyway with a 643E Aged Bronze finish. If the opening has to visually match satin brass or satin chrome trim, the 488K85 finishes cover that; the Schlage core comes in the darker bronze.
