Corbin Russwin 487K17 27B1 626 – Frequently Asked Questions

1) Will a 487K17 plug work in my existing Corbin Russwin mortise cylinder?
It fits 1-1/2 inch Corbin Russwin mortise cylinder housings and is built as a drop-in replacement for worn or rekeyed plugs in compatible Corbin Russwin hardware. Two things have to match: the housing has to be a 7-pin X Class shell (a 6-pin or non-X Class body won't take it), and your keying system has to be on the 27B1 keyway. A plug in a different keyway will not accept your existing keys.
2) What does the 27B1 keyway on this Corbin Russwin plug mean for my keying system?
27B1 is the factory-specified keyway on this plug, so it keys into an existing Corbin Russwin system already cut on 27B1. That is what keeps one key working across a building after a rekey. If your doors are on a different Corbin Russwin section, order the plug in that keyway, because the keyway is not something you can change in the field.
3) If I need a complete mortise cylinder rather than just a replacement plug, what should I look at instead of the Corbin Russwin 487K17?
The 487K17 27B1 is a 7-pin X Class replacement cylinder plug for 1-1/2 inch mortise cylinder applications - it is the keyed plug that goes into an existing housing, not a whole cylinder. If the opening needs a complete mortise cylinder, the Adams Rite 4036 is a five-pin Grade 1 mortise cylinder, and the Detex MC65 is a 1-1/8 inch six-pin mortise cylinder cut to the Schlage C keyway.
4) We want to be able to swap keying without pulling the lock apart - is the 487K17 the right approach?
The 487K17 is a factory plug swapped into a Corbin Russwin mortise cylinder for worn or rekeyed applications, so the cylinder comes out of the lock to service it. If keying changes on demand are the goal, interchangeable core products are built for that: the BEST 1CB is a 150 Series interchangeable core cylinder, the BEST 1CDF is a drill-resistant patented 7-pin brass interchangeable core in the 150 Series, and the Schlage 20-057 is a six-pin full size interchangeable core rim cylinder with a convertible tailpiece cam.
5) Why choose a 7-pin X Class plug over a standard cylinder for a commercial building?
The 7-pin X Class configuration is about key control: more pin positions and a restricted platform mean keys are harder to duplicate and the masterkey system stays under control across a facility. If key control is the priority but you want an interchangeable core system instead of a fixed plug, a patented drill-resistant core like the BEST 1CDF 7-pin interchangeable core is the alternative approach, swapped by hand rather than pinned in a housing.
6) I need to rekey a lot of Corbin Russwin mortise locks. Does replacing the plug do it?
Yes, that's exactly what this part is for. Swapping the 487K17 plug into the existing 1-1/2 inch housing rekeys or refreshes the cylinder without pulling and replacing whole mortise cylinders, so long as every opening is on the 27B1 keyway and a 7-pin X Class housing. Standardizing on one keyway and one plug part number across the facility is what keeps the maintenance stock small.
7) Can I use a Schlage or BEST cylinder in place of this Corbin Russwin plug?
No. A Schlage rim cylinder such as the 20-021 with a vertical tailpiece cam, or a BEST interchangeable core like the 1CB, are different formats on different keyways and will not drop into a Corbin Russwin 7-pin X Class mortise housing. Stay with the Corbin Russwin plug for that housing, or replace the whole cylinder and re-key the opening to whichever platform you're standardizing on.
8) Is the 487K17 27B1 a substitute for a key-in-lever or key-in-knob cylinder?
No - the 487K17 is a mortise cylinder plug in the 1-1/2 inch mortise format. Key-in-lever and key-in-knob locks take a different cylinder body: the Kaba Ilco 1539 is a universal key-in-knob and lever cylinder, the Ilco 1599 is a key-in-knob replacement cylinder, the Ilco 1579 is a knob and lever cylinder for Sargent, and the Falcon A23161-05 G is a six-pin G keyway key-in-lever cylinder supplied keyed different with two cut keys.
9) Will the Corbin Russwin 487K17 fit an Adams Rite MS1847 deadlock or a 5017 wood door deadlock?
Those Adams Rite deadlocks are served by cylinder pulls built for them: the 4024 mounts with a trim plate for the MS1847 deadlock/deadlatch, the 4025 is a five-pin tumbler cylinder pull with through-screws for the MS1847, and the 4026 is a five-pin cylinder pull for the Adams Rite 5017 wood door deadlock/deadlatch. The 487K17 is a Corbin Russwin plug for compatible Corbin Russwin mortise lock systems with the 27B1 keyway, so specify it where that keying system is already in place.
10) What is the difference between the 487K17 7-pin plug and a five-pin core like the BEST 1C5?
The 487K17 is a 7-pin X Class plug for 1-1/2 inch Corbin Russwin mortise cylinders, keyed to the 27B1 keyway for key control in commercial systems. The BEST 1C5 is a standard five-pin cylinder core from the Standard and Premium Cores line, so it belongs to a BEST core-based system rather than a Corbin Russwin mortise cylinder.
11) For a residential handleset or deadbolt retrofit, is the Corbin Russwin 487K17 the right part?
The 487K17 is a commercial component for Corbin Russwin mortise lock systems. Residential handleset and deadbolt retrofits are covered by the Medeco 1012040 six-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the Medeco 1065140 five-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, the Medeco 1065244 five-pin lazy motion rim cylinder with Emtek tailpiece, and the Medeco 1075127 five-pin lazy motion single cylinder for handlesets and deadbolts.
12) Is the 487K17 plug meant for commercial door hardware or residential locks?
Commercial. It's a genuine Corbin Russwin cylinder replacement part built to commercial tolerances, used in offices, schools, healthcare, government buildings, retail, warehouses and multi-tenant residential. For residential-style handleset and deadbolt cylinders, a retrofit unit like the Medeco 1075127 5-pin rim type lazy motion single cylinder is the different animal.
13) I need a cylinder that looks keyed but does nothing - can I use the 487K17?
No. The 487K17 is an operating 27B1 keyway plug for commercial mortise cylinders. For a non-functioning appearance, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter is the dummy product.
14) Our facility standardizes finishes across doors - what finish choices come with the 487K17 versus a comparable core?
The 487K17 plug is offered in 606 satin brass and 626 satin chrome, which covers the two most common commercial cylinder finishes. Among comparable cylinders, the Schlage 20-057-C full size interchangeable core is specified in 643E aged bronze with the C keyway, a darker finish for openings trimmed that way.
