Corbin Russwin 487K19 57B2 626 – Frequently Asked Questions

1) Will the 487K19 plug fit a 1-1/8 inch mortise cylinder?
No. This plug is sized for 1-3/4 inch mortise cylinder bodies. A 1-1/8 inch cylinder, which is the most common length on standard commercial mortise locks, needs a plug cut for that length. Measure the cylinder body before ordering, because the plug length has to match the housing it goes into.
2) Do I have to have Corbin Russwin 57B2 keys for this plug to work in my system?
Yes. The plug is cut to the Corbin Russwin 57B2 keyway, so it only accepts 57B2 keys and only keys into an existing 57B2 key control system. Ordering a different keyway for the same door means the keys on that opening will no longer match the rest of your Corbin Russwin masterkey system.
3) If the whole mortise cylinder needs replacing instead of just the plug, what can be used instead of the Corbin Russwin 487K19?
The 487K19 is a 7-pin X Class plug for 1-3/4 inch mortise cylinders, so it only serves a cylinder body that is otherwise sound. When the entire cylinder is being swapped, a complete mortise cylinder is the right item: the Detex MC65 is a 1-1/8 inch 6-pin commercial mortise cylinder cut to the Schlage C keyway, and the Adams Rite 4036 is a five-pin mortise cylinder in the 4036 Series. Both are whole cylinders rather than internal plugs, and neither carries the Corbin Russwin 57B2 keyway, so a keyed system built on 57B2 would need rekeying.
4) The opening is an aluminum storefront door with an Adams Rite deadlock. Is the Corbin Russwin 487K19 the part for it?
No. The 487K19 is a plug for 1-3/4 inch Corbin Russwin mortise cylinders. For Adams Rite storefront deadlocks, the 4024 cylinder pull mounts with a trim plate and the 4025 five-pin tumbler cylinder pull mounts with through-screws, both designed for use with the Adams Rite MS1847 deadlock/deadlatch; the 4026 five-pin tumbler cylinder pull is designed for the Adams Rite 5017 wood door deadlock/deadlatch. Choose by the deadlock model and door material.
5) Is a BEST interchangeable core the same thing as the Corbin Russwin 487K19 plug?
No. The 487K19 is a replacement plug that goes inside an existing 1-3/4 inch Corbin Russwin mortise cylinder and is cut to the 57B2 keyway. BEST interchangeable cores such as the 1C Series standard 5-pin core, the Peaks 1CB 150 Series core, and the drill resistant 1CDF 7-pin brass 150 Series core are removable cores that pull out of a core housing with a control key. They are not internal plugs for a Corbin Russwin mortise cylinder body.
6) What should I order instead of the Corbin Russwin 487K19 if the opening uses a rim exit device rather than a mortise lock?
The 487K19 plug is built for 1-3/4 inch mortise cylinder bodies, so it does not serve rim-prepped hardware. For a rim application, Schlage's 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam; the 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam. Match the cam orientation to what the exit device chassis calls for.
7) What is the advantage of a 7-pin X Class plug over a standard 6-pin cylinder?
The 7-pin X Class configuration gives higher key control and security than standard 5- or 6-pin cylinders, which matters where unauthorized key duplication is the real risk rather than physical attack. For comparison, common 6-pin commercial cylinders in the same category include the Schlage 20-021 rim cylinder and the Falcon A23161-05 G key-in-lever cylinder in the G keyway.
8) Can I use this plug as an interchangeable core to rekey a door quickly?
No. This is a mortise cylinder plug, not a removable core. Rekeying with it means pulling the cylinder and servicing it. If you want core swapping without disassembly, look at interchangeable core products such as the BEST 1CB 150 Series core, the BEST 1CDF drill resistant 7-pin brass core, or a Schlage 20-057 full size interchangeable core.
9) We want key control across a building without buying 7-pin Corbin Russwin plugs for every cylinder. What are the alternatives?
The 487K19 delivers key control through a 7-pin X Class plug keyed to the 57B2 keyway inside existing Corbin Russwin mortise cylinders, which keeps the installed cylinder bodies in place. If you are standardizing a facility instead, an interchangeable core platform lets you rekey by pulling cores: the BEST 1CDF is a drill resistant preferred patented 7-pin brass core in the 150 Series, and Schlage's 20-057-C is a full size interchangeable core in the C keyway, finish 643E Aged Bronze. Those are system changes rather than in-place plug swaps.
10) Will a Kaba Ilco replacement cylinder work in place of the Corbin Russwin 487K19?
Not in the same hole. The 487K19 is a mortise cylinder plug. The Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the 1549 is a key-in-deadbolt cylinder, the 1579 is a knob and lever cylinder for Sargent, and the 1599 is a key-in-knob replacement cylinder - all four are listed with a deadbolt product function and are built for knob, lever, or deadbolt chassis rather than a mortise cylinder body. Use them when the hardware being serviced is a key-in-lever or deadbolt, not a mortise lock.
11) We service Falcon and Medeco hardware too. Which cylinder parts cover those instead of the Corbin Russwin 487K19?
The 487K19 plug is specific to Corbin Russwin 1-3/4 inch mortise cylinders and the 57B2 keyway. For Falcon key-in-lever hardware, the A23161-05 G is a 6-pin G keyway key-in-lever cylinder supplied keyed different with two cut keys. On the Medeco side, the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, the 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece, and the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. Pick by the lock chassis being serviced.
12) Our specification calls for a Grade 1 cylinder. Does the 487K19 satisfy that, or is there another option?
The 487K19 is a commercial-grade Corbin Russwin replacement plug for mortise cylinders, sold as a manufacturer-sourced service part rather than a graded assembly. Where a drawing calls out a Grade 1 cylinder as a complete unit, the Adams Rite 4036 mortise cylinder is listed as Grade 1 in the 4036 Series with a 1/2 inch minimum door thickness. Confirm keyway and cylinder length against the existing system before substituting.
13) What finishes does the Corbin Russwin 487K19 plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the visible face of the cylinder and the surrounding trim, since the plug face is the part you see through the escutcheon or rose.
14) Is the 487K19 plug suitable for a school or hospital with heavy door traffic?
It's built for commercial service, and typical uses include educational facilities, healthcare institutions, government buildings, offices, retail, warehouses, and multi-tenant residential. It's a genuine Corbin Russwin replacement part, so it meets original equipment specs for the cylinders it goes into, which is what keeps a standardized facility key system intact after a repair.
15) Does the Corbin Russwin 487K19 come in a finish that will match satin chrome hardware, or do I need a different brand?
No need to change brands for finish. The 487K19 plug is offered in 606 Satin Brass and 626 Satin Chrome, so it can be coordinated with either brass-tone or chrome-tone commercial trim. Among comparable cylinders, the Schlage 20-057-C is listed in 643E Aged Bronze, a darker tone if the opening calls for it.
16) I only need a keyed pull or a non-functional cylinder for appearance. Is the 487K19 the right choice?
The 487K19 is a working 7-pin X Class plug keyed to the 57B2 keyway, intended to restore key operation in a Corbin Russwin mortise cylinder. If the opening needs a cylinder that is present but does not operate a lock, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter fills a rim prep without keyed function. The Emtek CY4 cylinder is another single-cylinder part sold in the Parts series.
