Corbin Russwin 487K11 BL 626 – Frequently Asked Questions

1) Is the Corbin Russwin 487K11 BL a complete mortise cylinder or just the plug?
It's the plug only. The 487K11 BL is an Individual X Class replacement plug for 1-1/8 inch mortise cylinder applications, not a full cylinder assembly. If you need a complete mortise cylinder to drop into a lock case, this isn't it. Order it when you're rebuilding or rekeying an existing Corbin Russwin mortise cylinder housing and only the plug needs to change.
2) Will a 487K11 BL plug work in my Schlage or BEST cylinder?
No. The plug is cut for the Corbin Russwin BL keyway and is built to integrate with compatible Corbin Russwin mortise cylinder assemblies. It won't drop into another manufacturer's housing. If you're working on Schlage hardware, the Schlage 20-021 and 20-022 rim cylinders are Schlage-brand parts; for BEST interchangeable core openings, the BEST 1C Series 5-pin core is the BEST-brand equivalent path.
3) Does the 487K11 BL come in 5-pin or 6-pin?
Both. The plug is offered in 5 and 6-pin configurations, so it can be matched to whatever pin count your existing Corbin Russwin keying program runs. Specify the pin count when you order, since a 6-pin plug keyed into a 5-pin system won't follow your master key hierarchy.
4) If I need a complete 1-1/8 inch mortise cylinder rather than just a replacement plug, what should I order?
The Corbin Russwin 487K11 BL is a replacement plug for 1-1/8 inch mortise cylinder applications, so it goes into an existing cylinder shell rather than replacing the whole cylinder. If the whole cylinder needs to come out, the Detex MC65 is a complete 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway, and the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security. Note that both of those are supplied in their own keyways, not the Corbin Russwin BL keyway, so they will not operate on a BL key system.
5) We want to rekey doors without pulling cylinders apart. Is there an interchangeable core option instead?
The Corbin Russwin 487K11 BL is a plug that is pinned and installed into a mortise cylinder, so rekeying means servicing the cylinder. For keying changes made by pulling a core with a control key, look at full size and small format interchangeable core products: the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam, the Schlage 20-057-C is an FSIC core in the C keyway with a 643E Aged Bronze finish, and BEST offers the 1C Series standard 5-pin core and the 1CB Peaks 150 Series interchangeable core. Those are separate keying platforms from the Corbin Russwin BL system.
6) What does X Class mean on a Corbin Russwin cylinder plug?
Individual X Class is a keying designation. It identifies the plug as belonging to a specific keying system so it can be built into a master key hierarchy rather than being a generic keyed-different plug. If you run a facility-wide Corbin Russwin master key program, the X Class designation is what keeps the new plug inside that program.
7) Why choose the BL keyway plug for a building where I control key duplication?
The BL keyway is a Corbin Russwin keyway used for controlled key duplication, which is the point of specifying it in a commercial building: blanks aren't freely available the way a common hardware-store keyway is. Combined with the Individual X Class keying designation, it lets a facility keep tenant, staff, and master levels separate on one program.
8) Can a rim cylinder be used in place of a mortise cylinder plug?
No. The Corbin Russwin 487K11 BL is a plug for 1-1/8 inch mortise cylinder assemblies, which thread into the lock case and drive a cam. Rim cylinders such as the Schlage 20-021, a 6-pin rim cylinder with a vertical tailpiece cam, and the Schlage 20-022, the same cylinder with a horizontal tailpiece cam, mount through the door and drive an exit device or rim lock by tailpiece. They are different cylinder formats and are not interchangeable.
9) The cylinder I am servicing is in a key-in-lever lockset, not a mortise lock. Does the 487K11 plug fit?
No. The Corbin Russwin 487K11 BL is built for 1-1/8 inch mortise cylinder assemblies. Key-in-knob and key-in-lever cylinders are a different body style: the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T series with a 6-pin G keyway supplied keyed different with two cut keys, the Kaba Ilco 1539 Series is a universal key-in-knob and lever cylinder, and the Kaba Ilco 1599 is a key-in-knob replacement cylinder. Match the cylinder format to the lockset before ordering.
10) What do I use if the cylinder is going into a deadbolt instead of a mortise lock?
The Corbin Russwin 487K11 BL plug serves mortise cylinder assemblies. For deadbolt applications, the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder and the Kaba Ilco 1579 is a knob and lever cylinder for Sargent, both listed with a deadbolt function; on the retrofit side, Medeco offers the 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts and the 1075127 5-pin rim type lazy motion single cylinder for handlesets and deadbolts.
11) For an aluminum storefront with an Adams Rite MS1847 deadlock, is this the right cylinder part?
The Corbin Russwin 487K11 BL is a plug for 1-1/8 inch mortise cylinders and is not a storefront pull assembly. For MS1847 deadlock and deadlatch openings, the Adams Rite 4024 cylinder pull mounts with a trim plate and the Adams Rite 4025 is a five pin tumbler cylinder pull using through-screws; for wood door openings, the Adams Rite 4026 five pin tumbler cylinder pull is designed for the 5017 wood door deadlock and deadlatch.
12) I need drill resistance and a patented key. What are my options versus the BL keyway plug?
The Corbin Russwin 487K11 BL gives controlled key duplication through the BL keyway and supports master key hierarchy as an Individual X Class plug. If the specification calls for drill resistance with a patented key, the BEST 1CDF is a drill resistant preferred patented interchangeable core in 7-pin brass, 150 Series. That is an interchangeable core platform rather than a mortise cylinder plug, so the housing and keying system differ.
13) What finishes is the Corbin Russwin 487K11 BL plug available in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the cylinder face and the rest of the trim on the opening, since the plug face is the visible part once the cylinder is assembled.
14) Is this plug suitable for a high-traffic commercial building or is it residential grade?
Commercial. The 487K11 BL is classed as commercial door hardware and is intended for professional replacement and service work in commercial mechanical lock assemblies, including office buildings, schools, healthcare, government facilities, and multi-tenant residential properties.
15) Is there a non-keyed option if the opening only needs the look of a cylinder?
The Corbin Russwin 487K11 BL is a functioning keyed plug in the BL keyway, available in 5 and 6-pin configurations, so it is not a blank filler. Where an opening needs a cylinder appearance without keying, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter is the dummy option, though it is a rim format rather than a mortise plug.
