Corbin Russwin 488K84 27B1 626 – Frequently Asked Questions

1) What is the difference between the B1 and B2 keyway options on the 488K84 plug?
B1 and B2 are two separate keyway profiles within the Corbin Russwin B family, and they are the two keyway choices offered on the 488K84 plug. A plug cut for B1 will not accept a B2 key and vice versa, so match the plug to the keyway already running in your master key system. If your existing keys are stamped with the keyway, use that stamp to pick.
2) Which pin depth should I order for a Corbin Russwin 488K84 plug?
Four pin depth codes are offered: 27, 57, 67 and 77. That code has to match the depth series your key system was set up on, because it governs how the plug is pinned against your existing keys. A locksmith rekeying to an existing system should pull the code off the keying schedule or the cylinder being replaced rather than guessing.
3) Does the 488K84 come in 5-pin and 6-pin?
Both. The plug is offered in 5-pin and 6-pin configurations so it can match whatever chamber count the existing 3000 rim cylinder and the building's key system use. Mixing pin counts breaks the keying, so order the count already in service.
4) If I need a whole rim cylinder instead of just a plug, what are my options?
For a complete rim cylinder rather than an internal plug, the Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same in a horizontal tailpiece cam, both supplied with two keys. Match the cam orientation to what your exit device requires. Note those are Schlage keyways, so they will not key into a Corbin Russwin B system.
5) If I need a complete rim cylinder rather than just a plug, what should I order?
The Corbin Russwin 488K84 27B1 is an individual X Class plug, a replacement part for the 3000 Rim Cylinder, so it does not include the shell, cam or keys. For a complete rim cylinder assembly, the Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and two keys, and the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam and two keys. Choose the cam orientation your exit device or rim lock requires.
6) We want to be able to rekey doors without disassembling cylinders. Is a plug replacement the right approach?
The Corbin Russwin 488K84 27B1 is an individual plug that is fitted into a 3000 Rim Cylinder, so rekeying means working on the cylinder internals. If you want key changes done by swapping a core instead, look at interchangeable core products: the BEST 1C Series standard 5-pin cylinder core, the BEST Peaks 1CB 150 Series interchangeable core cylinder, or the Schlage 20-057 6-pin full size interchangeable core rim cylinder with convertible tailpiece cam. Those change the keying architecture of the opening rather than repairing the existing Corbin Russwin cylinder.
7) What does X Class mean on a Corbin Russwin cylinder plug?
X Class is Corbin Russwin's keying class designation. Ordering the plug in the X Class keeps the cylinder inside the manufacturer's keying hierarchy, which is what lets it sit under an existing master key system with the key control intact. If your facility is keyed in a different class, this plug is the wrong part for that system.
8) Can I use the 488K84 plug to rekey rim cylinders across a whole building?
That is the usual reason to buy it. For facilities standardizing on Corbin Russwin 3000 rim cylinders, ordering plugs in one keyway and one pin depth lets maintenance swap internals and rekey openings without replacing whole cylinders. It is a commercial part, used in offices, schools, healthcare, government buildings, retail, warehouses and multi-tenant residential.
9) Is an interchangeable core a better choice than replacing cylinder plugs?
Different approach. A plug like the 488K84 is pinned into a fixed rim cylinder, so rekeying means pulling the cylinder apart. With an interchangeable core system you pull the core with a control key and drop a new one in, no disassembly. If you are rebuilding a keying program from scratch, the BEST 1C Series standard 5-pin core or the 1CB Peaks 150 Series core are FSIC/SFIC options worth considering; for existing Corbin Russwin 3000 rim cylinders, the plug is the correct repair.
10) Is the 488K84 plug an option for a mortise cylinder application?
No. The Corbin Russwin 488K84 27B1 plug is built for the Corbin Russwin 3000 Rim Cylinder, which is a rim format. For mortise prep, the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway, and the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder for doors 1/2 inch and up. Neither uses the Corbin Russwin B keyway, so factor keying into the decision.
11) What looks like a substitute for the 488K84 plug but will not work?
Cylinders sold for key-in-knob, lever or deadbolt use are a common mix-up. The Kaba Ilco 1539 key-in-knob/lever universal cylinder, the 1549 key-in-deadbolt cylinder, the 1579 knob and lever cylinder for Sargent, and the 1599 key-in-knob replacement cylinder are all deadbolt-function replacement cylinders for lock bodies, not plugs for a rim cylinder. The Falcon A23161-05 G is likewise a key-in-lever cylinder, 6-pin in the G keyway. The Corbin Russwin 488K84 27B1 is the internal plug for a 3000 Rim Cylinder in the Corbin Russwin B keyway.
12) I need a rim cylinder for a residential handleset or deadbolt, not a commercial exit device. What are my options?
The Corbin Russwin 488K84 27B1 plug is a commercial part for the 3000 Rim Cylinder. For handleset and deadbolt work, the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the Medeco 1065244 is a 5-pin lazy motion rim cylinder with an Emtek tailpiece, and the Medeco 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder.
13) We specify drill resistance on high security openings. What should I look at instead of a standard plug?
The Corbin Russwin 488K84 27B1 is a standard commercial X Class plug for the 3000 Rim Cylinder in 5-pin and 6-pin configurations. Where a drill resistant, patented key control cylinder is required, the BEST 1CDF is a drill resistant preferred patented interchangeable core 7-pin brass cylinder in the 150 Series. That is a different keying platform, so it is a change of system rather than a repair of the existing Corbin Russwin cylinder.
14) The opening only needs a pull with no keyed function. Do I still need a cylinder plug?
No. The Corbin Russwin 488K84 27B1 plug carries the pinning and keyway that make a 3000 Rim Cylinder operable, so it is only needed where the cylinder is keyed. For a dummy application, the BEST 12E Series dummy rim cylinder has a 1-5/32 inch diameter. On Adams Rite narrow stile doors the 4024 cylinder pull mounts with a trim plate for the MS1847 deadlock/deadlatch, the 4025 is a five pin tumbler cylinder pull with through-screws for the same MS1847, and the 4026 is a five pin tumbler cylinder pull for the 5017 wood door deadlock/deadlatch.
