Corbin Russwin 487K11 57C1 626 – Frequently Asked Questions

1) Can I pin the 487K11 plug for a 6-pin master key system?
Yes. The plug takes both 5-pin and 6-pin arrangements, so it works whether your building is keyed on a 5-pin system or a 6-pin master key setup. Pinning is done by the locksmith at the bench; the plug ships as a bare component of the cylinder.
2) Will this Corbin Russwin plug fit a rim cylinder or a key-in-knob cylinder?
No. The 487K11 is built for 1-1/8 inch mortise cylinder housings only. For rim applications, look at rim cylinders such as the Schlage 20-021 with vertical tailpiece cam or the 20-022 with horizontal cam. For key-in-knob or lever replacement, the Kaba Ilco 1599 key-in-knob cylinder is the type you want.
3) I need a complete 1-1/8 inch mortise cylinder, not just the plug. What should I order instead of the Corbin Russwin 487K11?
The Corbin Russwin 487K11 57C1 is a cylinder plug only, a replacement component for 1-1/8 in. mortise cylinder applications, so it will not fill a mortise prep on its own. For a complete unit, the Detex MC65 is a 1-1/8 in. six-pin mortise cylinder in the Schlage C keyway, and the Adams Rite 4036 is a Grade 1 mortise cylinder in the 4036 series with a 1/2 in. minimum door thickness. Both arrive as assembled cylinders rather than a bare plug.
4) Is a BEST interchangeable core an equivalent to the Corbin Russwin 487K11 57C1 plug?
No. The 487K11 57C1 is an individual X Class plug pinned 5 or 6 pins for the 57C keyway, serviced inside a Corbin Russwin mortise cylinder shell. A BEST 1C Series standard 5-pin core or the Peaks 1CB 150 Series interchangeable core is a removable figure-eight core that drops into BEST interchangeable-core housings, and the BEST 1CDF is a drill-resistant patented 7-pin brass core in the 150 series. Those are a different keying platform and different housing, so they are alternates only if the opening is already built for interchangeable core.
5) My exit device takes a rim cylinder. Will the Corbin Russwin 487K11 57C1 work?
No. The 487K11 57C1 is built for 1-1/8 in. mortise cylinder applications. For rim-prepped devices, Schlage Commercial offers the 20-021 rim cylinder with a vertical tailpiece cam and the 20-022 with a horizontal tailpiece cam, both six-pin and supplied with two keys. If the facility keys on full size interchangeable core, the Schlage 20-057 is a six-pin FSIC rim cylinder with a convertible tailpiece cam.
6) We standardize on Schlage C keyway. How does that affect choosing the Corbin Russwin 487K11 57C1?
The 487K11 plug is cut for the Corbin Russwin 57C keyway and is offered in C1 and C2 keyway options with 606 satin brass and 626 satin chrome finishes, so it stays inside a Corbin Russwin keying system. A facility keyed to Schlage C would instead look at the Detex MC65, a 1-1/8 in. six-pin mortise cylinder in the Schlage C keyway, or the Schlage 20-057-C full size interchangeable core in the C keyway, 643E aged bronze.
7) We rekey a lot of doors in one building. Is a plug like this or an interchangeable core the better way to go?
Depends on how often you rekey. Swapping a plug means pulling the cylinder and doing bench work each time, which suits occasional service on an installed Corbin Russwin mortise system. If you rekey frequently, an interchangeable core system lets you pull and replace the core with a control key at the door, for example the BEST 1C Series 5-pin core or the Schlage 20-057 6-pin FSIC rim cylinder. Moving to IC hardware is a system change, not a drop-in for a 57C mortise plug.
8) Will a 57C plug work in a Corbin Russwin cylinder that is keyed to a different Corbin Russwin keyway?
No. The plug has to match the key section of the system. A 57C X Class plug accepts 57C keys only, so if the building is keyed on a different Corbin Russwin section, the keys will not enter. Confirm the key section stamped on your existing keys before ordering C1 or C2.
9) What do I use for a key-in-lever or key-in-knob lock instead of the 487K11 57C1?
The 487K11 57C1 plug serves mortise cylinders, not knob or lever cylinder bodies. For key-in-lever work, the Falcon A23161-05 G is a key-in-lever cylinder for the RU/T series with a six-pin G keyway, keyed different with two cut keys. Kaba Ilco offers the 1539 Series universal key-in-knob/lever cylinder, the 1579 for Sargent knobs and levers, and the 1599 key-in-knob replacement cylinder.
10) We are replacing cylinders in residential-style deadbolts and handlesets. Is the Corbin Russwin 487K11 the right part?
The 487K11 57C1 is a commercial mortise cylinder plug, so it does not serve deadbolt or handleset cylinder positions. Kaba Ilco lists the 1549 Series key-in-deadbolt cylinder for deadbolt function. Medeco offers the 1012040 six-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065140 five-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, the 1065244 five-pin lazy motion rim cylinder with an Emtek tailpiece, and the 1075127 five-pin lazy motion single cylinder for handlesets and deadbolts.
11) Our doors are Adams Rite narrow stile aluminum. Can we pin a 487K11 57C1 for them?
The 487K11 57C1 is a plug for Corbin Russwin 1-1/8 in. mortise cylinders and is not an Adams Rite part. For MS1847 deadlock and deadlatch openings, Adams Rite offers the 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws. For a wood door with the 5017 wood door deadlock or deadlatch, the 4026 is the five pin tumbler cylinder pull.
12) What finishes does the 487K11 57C1 plug come in?
Satin brass (606) and satin chrome (626). Both C1 and C2 keyways are offered in each finish, so match the plug to the cylinder face and the rest of the trim on the opening.
13) Is the 487K11 57C1 suitable for commercial buildings or is it residential hardware?
Commercial. It is built to Corbin Russwin commercial door hardware standards and is used in offices, schools, healthcare and government facilities, multi-tenant residential, retail, and warehouse work where Corbin Russwin mortise locks are already installed.
14) I need a non-functioning cylinder just to fill a hole. Is a plug like the 487K11 what I want?
No. The 487K11 57C1 is a keyed working plug pinned 5 or 6 pins in the 57C keyway for live cylinder operation. Where only a blank filler is needed on a rim prep, the BEST 12E Series dummy rim cylinder with a 1-5/32 in. diameter is the purpose-built dummy. The Emtek CY4 cylinder is also sold individually as a parts item.
