Corbin Russwin 487K19 57A1 626 – Frequently Asked Questions

1) Can I rekey the 487K19 plug into an existing Corbin Russwin master key system?
Yes, within the 57A1 keyway. It is a 7-pin X Class plug, so it pins to a 7-pin X Class system on the 57A1 keyway and can be keyed alike, keyed different, or mastered to match the rest of the building by your locksmith. X Class is a restricted, key-controlled family, so blanks and cuts come through that program.
2) If the whole mortise cylinder needs replacing instead of just the plug, what complete mortise cylinder can be used?
The Corbin Russwin 487K19 57A1 is a replacement cylinder plug only, intended to service an existing Corbin Russwin mortise cylinder housing. When the entire cylinder is being replaced, a complete mortise cylinder is the right item instead: the Adams Rite 4036 is a five-pin mortise cylinder rated Grade 1 with a 1/2 inch minimum door thickness, and the Detex MC65 is a 1-1/8 inch six-pin mortise cylinder cut to the Schlage C keyway. Both are full cylinders, so they come with their own keyway rather than working with 57A1 keys.
3) What is the difference between a mortise cylinder plug like the 487K19 and an interchangeable core such as the BEST 1CB?
The Corbin Russwin 487K19 57A1 is a 7-pin X Class plug that fits inside a 1-3/4 inch mortise cylinder housing, so servicing it means pulling the cylinder and rebuilding it. An interchangeable core system works differently: the BEST Peaks 1CB is a 150 Series interchangeable core cylinder, and the BEST 1CDF is a drill resistant patented interchangeable core in 7-pin brass, both designed to be swapped as a core without disassembling the housing. Schlage's 20-057 is a 6-pin full size interchangeable core rim cylinder in the same vein. Choose the plug when keeping the existing Corbin Russwin 57A1 keying system, and a core platform when rekeying by core swap is the goal.
4) My building uses interchangeable cores, not mortise cylinders. Is this the right part?
No. The 487K19 is a fixed mortise cylinder plug, so it does not serve an IC housing. For interchangeable core openings look at full size or small format cores such as the BEST 1CB 150 Series interchangeable core, the BEST 1CDF drill-resistant 7-pin core, or the Schlage 20-057 6-pin FSIC rim cylinder.
5) Will this plug fit a rim cylinder or an exit device cylinder?
No. It is dimensioned for the 1-3/4 inch mortise format and will not serve a rim housing. Rim applications take a rim cylinder with a tailpiece, such as the Schlage 20-021 with a vertical tailpiece cam or the 20-022 with a horizontal cam.
6) We need a cylinder for a key-in-lever or deadbolt, not a mortise lock. What should be ordered instead of the 487K19?
The Corbin Russwin 487K19 57A1 plug serves mortise cylinder assemblies, so key-in-lever and deadbolt bodies take a different part. Kaba Ilco offers the 1539 Series key-in-knob and lever universal cylinder, the 1549 Series key-in-deadbolt cylinder, the 1579 knob and lever cylinder for Sargent, and the 1599 key-in-knob replacement cylinder. Falcon's A23161-05 G is a key-in-lever cylinder in the RU/T Series with a 6-pin G keyway, keyed different and supplied with two cut keys.
7) Will a rim cylinder work in place of the Corbin Russwin 487K19 mortise plug?
No. The 487K19 57A1 is built for a 1-3/4 inch mortise cylinder format, which threads into a mortise lock body. Rim cylinders mount through the door and drive an exit device or rim lock with a tailpiece: the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same cylinder with a horizontal tailpiece cam, while the BEST 12E Series dummy rim cylinder runs 1-5/32 inch in diameter. Those are not interchangeable with a mortise plug.
8) Is there a simpler 5-pin alternative to the 7-pin X Class 487K19 plug?
The 487K19 57A1 is a 7-pin X Class plug, which is the higher-pin-count configuration Corbin Russwin uses for key control on the 57A1 keyway. Where a 5-pin cylinder suits the opening, the BEST 1C Series standard 5-pin cylinder core and the Adams Rite 4036 five-pin mortise cylinder are both 5-pin designs. A 5-pin part cannot accept 57A1 7-pin keys, so it means moving that door onto a different keying system.
9) Can the 487K19 plug be used on a narrow stile aluminum door with an MS deadlock?
Not on its own. The Corbin Russwin 487K19 57A1 is a plug for a 1-3/4 inch mortise cylinder housing. Adams Rite narrow stile deadlocks take dedicated cylinder pulls: the 4024 cylinder pull mounts with a trim plate for MS1847 deadlock and deadlatch systems, the 4025 is a five pin tumbler cylinder pull with through-screws for the MS1847, and the 4026 is a five pin tumbler cylinder pull for wood door applications with the 5017 wood door deadlock or deadlatch.
10) For residential handlesets and deadbolts in a multifamily property, is the 487K19 the right cylinder part?
The 487K19 57A1 is designated a commercial replacement part for Corbin Russwin mortise cylinder assemblies, so it belongs on mortise lock hardware. Residential-style handlesets and deadbolts are served by different retrofit cylinders: the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065140 is a 5-pin retrofit for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, the 1065244 is a 5-pin lazy motion rim type cylinder with an Emtek tailpiece, and the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. Emtek also lists the CY4 cylinder sold each.
11) We want a drill resistant cylinder for a high-security opening. How does that compare with the 487K19 X Class plug?
The Corbin Russwin 487K19 57A1 uses a 7-pin X Class configuration on the 57A1 keyway for key control in commercial applications. If drill resistance is the priority, the BEST 1CDF is a drill resistant preferred patented interchangeable core in 7-pin brass, 150 Series. Both are 7-pin, but the 1CDF is a full interchangeable core on its own patented system rather than a plug that keeps a door on 57A1 keys.
12) What finishes does the Corbin Russwin 487K19 57A1 plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the cylinder ring and trim already on the door, since the plug face is the visible part once assembled.
13) I manage a commercial building, is this part meant for heavy-traffic doors?
Yes, it is a commercial-grade component intended for commercial door hardware, not residential retrofits. Typical use is offices, schools, healthcare, government buildings, retail, warehouses, and multi-tenant residential where Corbin Russwin mortise cylinders are already standard.
14) Does the Schlage 20-057-C give the same finish-matching flexibility as the 487K19 plug?
The Corbin Russwin 487K19 57A1 plug is offered in 606 satin brass and 626 satin chrome, so it can be matched to surrounding trim. The Schlage 20-057-C, a full size interchangeable core cylinder on the C keyway, is listed in 643E aged bronze. They are also different parts in kind: one is a mortise cylinder plug, the other a complete interchangeable core.
