Corbin Russwin 487K15 27A1 626 – Frequently Asked Questions

1) Will a 27A1 keyway plug work with my existing Corbin Russwin keys?
Only if your system is already keyed in 27A1. The 487K15 plug is factory-specified to the 27A1 keyway, so it accepts 27A1 keys and fits into Corbin Russwin keying and key-interchange control built on that keyway. A cylinder cut for a different Corbin Russwin keyway family will not take a 27A1 key, so confirm the keyway stamped on the cylinder you are rebuilding before ordering.
2) What size mortise cylinder housing does the 487K15 plug fit?
It is dimensioned for 1-3/8 inch mortise cylinder housings, which is the common commercial mortise length. It is not the part for a 1-1/8 inch or 1-1/4 inch cylinder body.
3) Can I use the 487K15 to rekey a rim cylinder or an interchangeable core?
No. It's a mortise cylinder plug, so it belongs in a 1-3/8 inch mortise cylinder body. For rim applications look at the Schlage 20-021 (vertical tailpiece cam) or 20-022 (horizontal tailpiece cam) 6-pin rim cylinders. For interchangeable core systems, the BEST 1CB 150 Series core or the 1CDF drill-resistant 7-pin core are the core-based route.
4) If I need a complete mortise cylinder rather than just the plug, what should I order instead of the Corbin Russwin 487K15?
The 487K15 is a 7-pin X Class cylinder plug for 1-3/8 inch mortise cylinders - it is the keyed plug that goes into a mortise cylinder housing, not a finished cylinder you can thread into a lock case. If you need a complete mortise cylinder, the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder, and the Detex MC65 is a 1-1/8 inch six-pin mortise cylinder cut to the Schlage C keyway. Both arrive as assembled cylinders rather than a plug you pin and install into an existing shell.
5) We want to be able to rekey doors without pulling the cylinder apart - what is the alternative to the 487K15 plug?
The 487K15 is a pinned plug, so rekeying means disassembling the cylinder at the bench. An interchangeable core approach removes that step: the BEST 1CB is a 150 Series interchangeable core cylinder, the BEST 1CDF is a drill-resistant patented 7-pin interchangeable core in the 150 Series, and the Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam. With those, a control key pulls the core and a new core drops in.
6) What do I use if the opening is a key-in-lever or key-in-knob lock rather than a mortise lock?
The 487K15 plug is sized for 1-3/8 inch mortise cylinders and will not fit a knob or lever lock. For those openings, the Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the Kaba Ilco 1599 is a key-in-knob replacement cylinder, the Kaba Ilco 1579 is a knob and lever cylinder for Sargent locks, and the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T Series with a 6-pin G keyway, keyed different with two cut keys.
7) Will the 487K15 work on an aluminum storefront deadlock?
No - the 487K15 is a 1-3/8 inch mortise plug for Corbin Russwin mortise cylinder housings. For narrow stile storefront work, the Adams Rite 4024 is a cylinder pull with trim plate mounting for MS1847 deadlock and deadlatch systems, the 4025 is a five-pin cylinder pull with through-screws for the MS1847, and the 4026 is a five-pin cylinder pull intended for the 5017 wood door deadlock and deadlatch. Those are the parts matched to that hardware.
8) What finishes does the Corbin Russwin 487K15 plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one matching the cylinder collar and the lock trim on the door, since the plug face is what shows through the rose or escutcheon.
9) Why choose a 7-pin X Class plug over a standard 6-pin cylinder for a school or hospital?
The 7-pin X Class configuration gives more pin combinations and added pick resistance, which is what facilities use when they need tight key control across a large master key system. The description calls out commercial office, educational, healthcare, government, retail, industrial and multi-tenant residential use. A 6-pin commercial cylinder like the Detex MC65 or the Falcon A23161-05 G in a 6-pin G keyway is the simpler option when high-security key control is not the requirement.
10) I manage a building with mixed hardware. Can I standardize all my cylinders on the 487K15?
Only on the openings that already use 1-3/8 inch Corbin Russwin mortise cylinders keyed in 27A1. Doors with rim exit devices, key-in-lever locks, or interchangeable core hardware need a different cylinder format entirely, for example the Kaba Ilco 1599 key-in-knob replacement cylinder or a Schlage rim cylinder. A practical approach is to standardize by cylinder format first, then key the whole group to one system.
11) Is a rim cylinder like the Schlage 20-021 a substitute for the 487K15?
No. The 487K15 is a plug for a 1-3/8 inch mortise cylinder, which threads into a mortise lock case. The Schlage 20-021 and 20-022 are rim cylinders, mounted through the door and driven by a tailpiece - the 20-021 uses a vertical tailpiece cam and the 20-022 a horizontal one. They serve rim exit devices and rim locks, not mortise lock bodies, so the two are not interchangeable.
12) The 487K15 is 7-pin. What are the 5-pin and 6-pin options if our system does not run 7-pin?
The 487K15 plug is a 7-pin X Class configuration. If your keying system is built on shorter pin stacks, the BEST 1C5 is a standard 5-pin cylinder core, the Adams Rite 4036 is a five-pin mortise cylinder, and the Detex MC65 is a 6-pin mortise cylinder in the Schlage C keyway. Pin count has to match the system the key is cut for, so confirm your master key bitting before mixing stacks.
13) What is the equivalent part for a residential handleset or Kwikset deadbolt instead of the 487K15?
The 487K15 is a commercial part for Corbin Russwin mortise cylinder systems. For handleset and residential deadbolt retrofits, the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the Medeco 1065244 is a 5-pin rim lazy motion cylinder supplied with an Emtek tailpiece, and the Medeco 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders. The Emtek CY4 cylinder is sold individually for Emtek hardware.
14) Is this a genuine Corbin Russwin part or an aftermarket copy?
It's an OEM Corbin Russwin cylinder component built to factory specification, catalogued under model 487K15 27A1. That matters on a keyed system, because an aftermarket plug with slightly different pin chamber spacing can throw off a master keying schedule.
15) We need a non-keyed filler for an opening where the 487K15 would normally go - what is available?
The 487K15 is a keyed 7-pin plug, so it is not the part for a blank or inactive position. The BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter fills a cylinder opening without keying, which is the usual choice for an inactive leaf or a pull-side hole that needs to look finished.
16) Does the 487K15 in 626 Satin Chrome have a close match in another brand's finish offering?
The 487K15 plug is offered in 606 Satin Brass and 626 Satin Chrome. Among comparable cylinders, the Schlage 20-057-C is a full size interchangeable core cylinder in the C keyway supplied in 643E Aged Bronze, which is a darker finish than either 487K15 option. Match the finish to the exposed cylinder face and collar on the door, since the plug face is what shows.
