Corbin Russwin 488K85 27B1 626 – Frequently Asked Questions

1) What do I need to specify when ordering the 488K85 plug?
Three things: keyway, pin depth, and finish. Keyway is B1 or B2. Pin depth is offered as 27, 57, 67 or 77. Finish is 606 satin brass or 626 satin chrome. All four pin depths are available in both keyways and both finishes.
2) Difference between the B1 and B2 keyway on this Corbin Russwin plug?
B1 and B2 are two separate sectional keyway profiles within the Corbin Russwin B family. A key cut on a B1 blank will not enter a B2 plug and vice versa, so the plug has to be ordered in the same keyway the building is already keyed to. Both options are available in satin brass and satin chrome at every pin depth offered.
3) If the whole Corbin Russwin rim cylinder needs replacing instead of just the plug, what complete rim cylinder can go in?
The Corbin Russwin 488K85 is a replacement plug for the 3000-7 rim cylinder, so it only serves a cylinder body already in the door. When the body itself is being replaced, a complete rim cylinder is the item to order: the Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam supplied with 2 keys, and the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam. Cam orientation must match the exit device or rim lock it drives, and either one keys to a Schlage system rather than a Corbin Russwin B keyway.
4) Is a BEST interchangeable core the same kind of serviceable part as the Corbin Russwin 488K85 plug?
Both let you re-key a door without replacing the lock body, but they work differently. The 488K85 is an individual X Class 7-pin plug that is fitted into an existing Corbin Russwin 3000-7 rim cylinder, which means bench work on the cylinder. A BEST 1C Series standard 5-pin cylinder core or the 1CB 150 Series interchangeable core cylinder pulls out and drops in with a control key, and the 1CDF is a drill resistant patented interchangeable core in 7-pin brass in the 150 Series. Interchangeable cores are a different keying platform, so they do not operate a Corbin Russwin B keyway.
5) The opening needs a mortise cylinder, not a rim cylinder. What should I order instead?
The Corbin Russwin 488K85 plug belongs to a rim cylinder assembly, the 3000-7, so it will not serve a mortise prep. For mortise applications 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 6-pin commercial grade mortise cylinder in Schlage C keyway. Both are complete cylinders keyed to their own systems rather than a Corbin Russwin B keyway.
6) Can I keep my existing master key system if I replace the plug?
Yes, provided you order the matching keyway and pin depth. The B keyway profile is what keeps key interchange intact across the facility, so a plug ordered in the same B1 or B2 profile can be pinned to the existing master system by your locksmith. The plug arrives as a component, so pinning to your key schedule happens at installation.
7) I need an interchangeable core instead of a fixed plug. What are my options?
A plug like the 488K85 is a fixed component that gets pinned into the shell, so rekeying means pulling the cylinder apart. If you want to swap cores by hand without disassembly, look at an interchangeable core product instead: the BEST 1CB Peaks 150 Series interchangeable core, the BEST 1CDF drill resistant 7-pin brass core, or the Schlage 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam. Those change key control at the core rather than at the plug.
8) Does the 488K85 come with keys?
No. It is a replacement plug sold as a cylinder component, so it ships as the plug for your locksmith to pin and key. If you need a cylinder that arrives cut and keyed, a complete assembly such as the Schlage Commercial 20-022 rim cylinder, 6-pin with horizontal tailpiece cam and two keys, covers that.
9) Can I use this plug in a mortise cylinder?
No. The 488K85 is built for the 3000-7 rim cylinder, and rim and mortise cylinder bodies are different housings. For a mortise application, order a mortise cylinder such as the Detex MC65 6-pin with Schlage C keyway or the Adams Rite 4036 Grade 1 mortise cylinder.
10) We want a keyed-removable core setup on the exit devices instead of servicing plugs. What rim cylinder supports that?
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 20-057-C is a full size interchangeable core cylinder in C keyway with a 643E Aged Bronze finish. Those let a core be swapped at the door. The Corbin Russwin 488K85 takes the other approach: it is an individual X Class 7-pin plug that restores an existing 3000-7 rim cylinder in a B keyway, keeping the facility's current key interchange intact.
11) Will a Medeco or Kaba Ilco replacement cylinder work in place of the Corbin Russwin 488K85?
No, those address different hardware. The 488K85 is a component-level plug for a Corbin Russwin 3000-7 rim cylinder. The Medeco 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 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. Kaba Ilco's 1539 and 1599 are key-in-knob and lever replacement cylinders, and the 1579 is a knob and lever cylinder for Sargent. None of them is a plug for a 3000-7 body.
12) For an aluminum storefront with an Adams Rite deadlock, is the 488K85 relevant?
No. The Corbin Russwin 488K85 is a commercial replacement plug for the 3000-7 rim cylinder and is tied to Corbin Russwin hardware. Adams Rite storefront deadlocks use their own cylinder pulls: the 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws are both for the MS1847 deadlock/deadlatch, and the 4026 five pin tumbler cylinder pull is for the 5017 wood door deadlock/deadlatch. Match the pull to the deadlock model in the door.
13) Which finish should I pick, 606 or 626?
Two choices: 606 satin brass and 626 satin chrome. On a rim cylinder the plug face is the visible part on the outside of the door, so match it to the existing cylinder ring and the rest of the trim on the opening. Both finishes are offered in B1 and B2 and across all four pin depths.
14) Is the 488K85 plug suitable for commercial use, or is it a residential part?
It is a commercial cylinder component. Corbin Russwin lists it under commercial mechanical locks, and the typical uses are office buildings, schools, hospitals, government buildings, retail, warehouses and multi-tenant residential. The model designation is 488K85 27B1 for the 27 depth, B1 keyway version.
15) I need a rim cylinder that only fills the hole and is not keyed. Is there an option for that?
For a non-operating fill, the BEST 12E Series dummy rim cylinder has a 1-5/32 inch diameter and no keying function. The Corbin Russwin 488K85 is the opposite case: a 7-pin X Class plug that restores key operation in an existing 3000-7 rim cylinder, offered in B1 and B2 keyways with 27, 57, 67 and 77 pin depths in 606 Satin Brass and 626 Satin Chrome.
