Corbin Russwin 487K38 27A1 626 – Frequently Asked Questions

1) Will the 487K38 27A1 plug work in a standard Corbin Russwin mortise cylinder, or only the hotel version?
It is purpose-matched to the Corbin Russwin 1001 Hotel Mortise cylinder. Hotel-function cylinders work differently from standard mortise cylinders, so treat this plug as a 1001 Hotel part only. Confirm the cylinder you are servicing is the 1001 Hotel Mortise before ordering.
2) What keyway options are there on the Corbin Russwin 487K38 hotel plug?
Two keyway choices, A1 and A2, both within the Corbin Russwin A keyway family. Match whichever one your existing guest room keys are cut to; an A1 key will not operate an A2 plug.
3) I need a complete mortise cylinder, not just a plug. What should I order instead of the Corbin Russwin 487K38 27A1?
The 487K38 27A1 is a replacement cylinder plug for the Corbin Russwin 1001 Hotel Mortise cylinder, so it is the keyed plug assembly that drops into an existing housing rather than a whole cylinder. If the housing itself is damaged or missing, order a complete mortise cylinder such as the Detex MC65, a 1-1/8 inch 6-pin commercial mortise cylinder in the Schlage C keyway, or the Adams Rite 4036, a Grade 1 five-pin mortise cylinder in the 4036 Series. Note that both of those bring their own keyway rather than the Corbin Russwin A keyway, so an existing A keyway key system would not operate them.
4) Can I use a BEST interchangeable core instead of the Corbin Russwin 487K38 plug to rekey hotel guest rooms?
No, they are not interchangeable approaches. The 487K38 27A1 is an Individual X Class plug in the Corbin Russwin A keyway that serves the 1001 Hotel Mortise cylinder platform and supports 5-pin and 6-pin configurations. A BEST core such as the 1C Series standard 5-pin cylinder core, the Peaks 1CB 150 Series interchangeable core, or the drill-resistant 1CDF 7-pin 150 Series core requires housings prepped for a BEST figure-eight core and a BEST control key to remove it. Converting a hotel to interchangeable core means changing the cylinder housings, not just the plugs.
5) The opening is a narrow stile aluminum storefront door, not a hotel mortise lock. Does the 487K38 plug work there?
No. The 487K38 27A1 plug is matched to the Corbin Russwin 1001 Hotel Mortise cylinder used in hotel and lodging guest room hardware. For narrow stile aluminum openings, Adams Rite parts address that prep: the 4036 is a Grade 1 five-pin mortise cylinder with a 1/2 inch minimum door thickness, and the 4024 cylinder pull with trim plate mounting and the 4025 five-pin cylinder pull with through-screws are made for MS1847 deadlock and deadlatch systems. For a wood door deadlock, the Adams Rite 4026 five-pin cylinder pull suits the 5017 wood door deadlock and deadlatch.
6) What finishes does the Corbin Russwin 487K38 plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the existing cylinder face on the guest room doors, since the plug face is visible at the keyhole. Both finishes are offered with either the A1 or A2 keyway.
7) I need a whole cylinder, not just a plug. What else could I use?
A plug will not help if you need a complete cylinder. For a full 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 in the Schlage C keyway. Neither is a hotel-function cylinder, so they are substitutes for standard mortise prep, not for a 1001 Hotel lock.
8) We want to stop rekeying cylinders by hand across the property. Is there an interchangeable core option instead?
The 487K38 plug is a conventional keyed plug, so rekeying means pinning it. If you are standardizing a facility around fast core swaps, look at interchangeable core products instead: the BEST 1CB Peaks 150 Series interchangeable core, the BEST 1CDF drill resistant 7-pin brass core, or Schlage's 20-057 six-pin FSIC rim cylinder with convertible tailpiece cam. Those are a different platform, so they do not fit a 1001 Hotel Mortise housing.
9) Can I fit this plug into an existing master key system?
Yes, that is the point of it. Because it takes 5-pin or 6-pin configurations in the Corbin Russwin A keyway, it can be pinned into an established master keying program using the A1 or A2 profile already in use on the property.
10) What is the difference between the Corbin Russwin 487K38 plug and a Schlage 20-021 rim cylinder?
They serve different lock bodies. The 487K38 27A1 is a mortise-cylinder plug for the Corbin Russwin 1001 Hotel Mortise cylinder and installs inside that threaded cylinder housing. The Schlage 20-021 is a complete rim cylinder with a vertical tailpiece cam and two keys, mounting through the door to drive a surface rim device; the 20-022 is the same rim cylinder with a horizontal tailpiece cam. If the opening has an exit device with a rim cylinder, the Schlage parts apply; if it is a hotel mortise lock, the Corbin Russwin plug is the matching component.
11) We want to standardize on a small-format or full-size interchangeable core program instead of pinning plugs. What are the options?
The Corbin Russwin 487K38 27A1 is a pinned Individual X Class plug in the A keyway, so rekeying it means taking the cylinder apart at the bench. For a core-swap program, the Schlage 20-057 is a 6-pin full-size interchangeable core rim cylinder with a convertible tailpiece cam and two keys, and the 20-057-C is a full-size interchangeable core in the C keyway with a 643E aged bronze finish. BEST offers the 1C Series 5-pin core and the 1CB Peaks 150 Series core for small-format housings. All of these move the keyed element to a removable core rather than a fixed plug.
12) Is there an aftermarket replacement cylinder that works like the Corbin Russwin 487K38 for key-in-lever locks?
The 487K38 27A1 is specific to the Corbin Russwin 1001 Hotel Mortise cylinder and is not a key-in-lever part. For key-in-knob and key-in-lever bodies, Kaba Ilco offers universal-style replacements: the 1539 Series key-in-knob and lever cylinder, the 1579 knob and lever cylinder for Sargent, and the 1599 key-in-knob replacement cylinder; the 1549 Series is a key-in-deadbolt cylinder. Falcon also lists the A23161-05 G, a key-in-lever cylinder for RU/T series in a 6-pin G keyway, keyed different with two cut keys. These fit lever and knob chassis rather than a mortise cylinder shell.
13) Which cylinder should I use for a residential-style handleset or deadbolt rather than the Corbin Russwin 487K38?
The 487K38 27A1 is a commercial part built for the Corbin Russwin 1001 Hotel Mortise cylinder platform. For handlesets and deadbolts, Medeco lists retrofit options: the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder, 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. Emtek also offers the CY4 cylinder sold each.
14) Why does a cylinder plug list lever designs 27, 57, 67 and 77?
Those four design codes (27, 57, 67, 77) are how the part is ordered to match the lock trim family it is being fitted into on the 1001 Hotel Mortise platform. Order the code that corresponds to the hardware already on the door so the plug is supplied for the right configuration.
15) Is this an OEM Corbin Russwin part or an aftermarket copy?
Genuine Corbin Russwin. The 487K38 27A1 is built to OEM specification as an authentic Corbin Russwin cylinder component, which is what keeps it keying and functioning correctly inside the factory 1001 Hotel housing.
16) Is the 487K38 plug suitable for hotel and institutional door hardware, or is it a residential part?
Commercial only. It is rated for commercial use and is aimed at guest room locks in hotels and lodging, plus institutional settings like healthcare, education, government buildings and multi-tenant residential where 1001 Hotel Mortise cylinders are in service.
17) I need a non-keyed filler for an opening, not a working plug. Is the Corbin Russwin 487K38 the right part?
No. The 487K38 27A1 is a functioning keyed plug supporting 5-pin and 6-pin configurations in the A keyway. If the requirement is a blank or non-operating cylinder to fill a prep, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter covers that role for a rim prep. Choose the Corbin Russwin plug only where the 1001 Hotel Mortise cylinder needs to key and operate.
