Corbin Russwin CR1080-114-A03-6-L4-626 – Frequently Asked Questions

1) Is the 1080 Series 114-A03 an interchangeable core cylinder or a fixed pinned cylinder?

It is a 6-pin Large Format Interchangeable Core (LFIC) mortise cylinder, which means the core pulls with a control key and can be swapped or re-keyed without taking the lock off the door. Its classification is conventional mortise, and two keys come with it.

2) Can I use this cylinder in a Schlage L9000 mortise lock?

Yes. The 114-A03 is stated as compatible with Schlage L9000 series mortise locks, along with all mortise locks and DL3000 deadlocks. Keep in mind the cam fitted is the A03 Adams Rite MS cam, so if your L9000 needs the Schlage cloverleaf cam instead, the 1080 platform's A06 Schlage Cloverleaf cam option is the one to specify.

3) What do I have to specify when ordering a Corbin Russwin 1080 mortise cylinder?

Two choices drive the order: keyway and finish. Keyways run the full Corbin Russwin range, 84 options including 27, 57, 59, 60, 67, 70, 77, 97, 98, 99, 252, AR, BL, BR, D1/D2, G, H1 through H8, L1 through L4 and N1 through N28. Finishes are 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 619 satin nickel, 625 bright chrome and 626 satin chrome. The 1-1/4 inch length and A03 cam are fixed on this configuration.

4) I need to match cylinders across a building on one master key system. Does this fit an existing Corbin Russwin keying system?

It does, provided you order it in the keyway your system already uses. The 1080 Series is built as the keying platform for Corbin Russwin openings, and 84 keyways are offered on the 114-A03, so a facility standardized on, say, 59A1 or N14 can keep the same keyway across mortise locks and DL3000 deadlocks. Because the core is LFIC, your locksmith can pin cores at the bench and drop them in later.

5) Which cam do I need if my lock is not an Adams Rite MS?

The 114-A03 carries the Adams Rite MS cam. If your hardware needs something else, the 1080 platform offers A01 Cloverleaf, A02 Straight, A04 for DL4000 Series, A05 for Adams Rite 4070, A06 Schlage Cloverleaf, A07 for DL4100, A62 900 KRM Straight, A92 and A93. Pull the existing cylinder and match the cam shape before ordering, since the cam, not the body, is what decides whether the lock throws.

6) Is this a mortise cylinder or a rim cylinder? I am not sure which my exit device takes.

The Corbin Russwin 114-A03 is a threaded mortise cylinder, not a rim cylinder. Mortise cylinders screw into a threaded hole in the lock case and drive a cam. Rim cylinders mount through the door from the back with a tailpiece and screws, which is what most rim exit devices use. For a rim application, Schlage's 20-021 (vertical tailpiece cam) and 20-022 (horizontal tailpiece cam) are 6-pin rim cylinders, and the 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece.

7) For an Adams Rite MS deadlock, should I use the Corbin Russwin 114-A03 or the Adams Rite 4036 mortise cylinder?

Both address Adams Rite hardware, from different directions. The Corbin Russwin 114-A03 is a 6-pin, 1-1/4 inch mortise cylinder factory-fitted with the A03 Adams Rite MS cam, available in the full Corbin Russwin keyway list so it drops into an existing Corbin Russwin master key system. The Adams Rite 4036 is a five-pin Grade 1 mortise cylinder in the 4036 Series with a 1/2 inch minimum door thickness. Choose the 114-A03 when the opening has to key to a Corbin Russwin system with 6-pin keying; choose the 4036 when a five-pin Adams Rite native cylinder is what the job calls for.

8) What is the difference between the Corbin Russwin 1080 Series 114-A03 mortise cylinder and the Detex MC65 mortise cylinder?

Both are 6-pin commercial mortise cylinders, but they are keyed into different systems and built to different lengths. The Corbin Russwin 114-A03 is a 1-1/4 inch conventional mortise cylinder fitted with the A03 Adams Rite MS cam, and it is offered across the Corbin Russwin keyway range including 27, 57A1, 59B2, 67, 77, N-series and H-series keyways. The Detex MC65 is a 1-1/8 inch mortise cylinder cut to the Schlage C keyway. If the building is mastered on a Corbin Russwin keyway, the 114-A03 is the one that keys into it; if the opening is standalone on Schlage C, the MC65 matches that keyway.

9) Can I use a rim cylinder like the Schlage 20-021 in place of a Corbin Russwin 1080 mortise cylinder?

No - those are two different cylinder formats and they are not interchangeable. The Corbin Russwin 114-A03 is a conventional mortise cylinder, threaded into the lock body and driven by a cam, and it is intended for mortise locks and DL3000 deadlocks. The Schlage 20-021 is a rim cylinder with a vertical tailpiece cam, which mounts through the door behind a rim exit device rather than threading into a mortise case. The Schlage 20-022 is the same rim cylinder with a horizontal tailpiece cam. Use a mortise cylinder for a mortise case and a rim cylinder for a rim device.

10) What should I order instead of the Corbin Russwin 1080 mortise cylinder for a key-in-lever or deadbolt opening?

The Corbin Russwin 114-A03 is a mortise cylinder for mortise lock cases and DL3000 deadlocks, so it is the wrong format for a key-in-lever or a tubular deadbolt. For key-in-lever work, the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T Series with a 6-pin G keyway, keyed different with 2 cut keys, and the Kaba Ilco 1539 is a key-in-knob and lever universal cylinder. For deadbolt openings, the Kaba Ilco 1549 is a key-in-deadbolt cylinder and the 1599 is a key-in-knob replacement cylinder. Keep the 114-A03 for the mortise cases.

11) Is a 1-1/4 inch mortise cylinder the right length for my door?

1-1/4 inch is the standard mortise cylinder length for typical commercial mortise lock preps on a 1-3/4 inch door, and that is what the 114-A03 measures. If the cylinder sits proud of the trim or recessed too deep on a thicker door or a heavy escutcheon, you need a longer body from the 1080 range rather than this one.

12) What is the difference between this and an Adams Rite 4036 mortise cylinder?

Both are mortise cylinders, but they sit in different keying systems. The Corbin Russwin 114-A03 is a 6-pin interchangeable core in the Corbin Russwin 1080 keyway family, so it belongs on a building already keyed Corbin Russwin. The Adams Rite 4036 is a five-pin Grade 1 mortise cylinder listed for 1/2 inch minimum door thickness and is the native cylinder for Adams Rite hardware. If the goal is one key across a mixed building, stay in one system.

13) Do I have to order separate cylinders for left-hand and right-hand doors?

No. The 114-A03 is non-handed, so one part number covers both hands and you can stock a single cylinder for the whole building. The cam does the work and it does not change with door hand.

14) Can I use this as a straight replacement for a failed cylinder without pulling the lock apart?

Yes, it is catalogued as a replacement part and threads into the existing mortise lock prep. With the LFIC design you can also change the core alone later without removing the lock from the door. Match three things off the old cylinder: the 1-1/4 inch length, the A03 Adams Rite MS cam, and your building's keyway.

15) Is a BEST interchangeable core the same thing as the Corbin Russwin 1080 LFIC mortise cylinder?

They are different pieces of the same idea. The Corbin Russwin 114-A03 is a complete mortise cylinder housing with the A03 Adams Rite MS cam, non-handed, supplied with 2 keys. BEST interchangeable core items are the cores themselves - the 1C5 is a standard 5-pin cylinder core, the 1CB is a 150 Series interchangeable core, and the 1CDF is a drill-resistant patented 7-pin interchangeable core in brass. A core alone does not thread into a mortise case; it seats in a housing. Order the 114-A03 when you need the mortise housing and cam for the lock body.

16) My Adams Rite MS1847 deadlock needs a cylinder pull rather than a cylinder - what is the alternative to the Corbin Russwin 114-A03?

The Corbin Russwin 114-A03 is the keyed mortise cylinder with the A03 Adams Rite MS cam, not the pull. For MS1847 deadlock and deadlatch openings that call for a cylinder pull, the Adams Rite 4024 is a cylinder pull with trim plate mounting and the 4025 is a five pin tumbler cylinder pull with through-screws, both designed for use with the MS1847. For a wood door application, the Adams Rite 4026 is a five pin tumbler cylinder pull for the 5017 wood door deadlock and deadlatch.

17) I need a cylinder for a rim exit device that will take an interchangeable core - is the Corbin Russwin 1080 the right part?

Not for a rim device. The Corbin Russwin 114-A03 is a conventional mortise cylinder. For rim applications on an interchangeable core system, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam supplied with 2 keys, and the 20-057-C is a full size interchangeable core cylinder in the C keyway with a 643E Aged Bronze finish. The 114-A03 is the part to order when the cylinder threads into a mortise case with an Adams Rite MS cam.

18) Will a Medeco retrofit cylinder work in the same opening as the Corbin Russwin 1080 mortise cylinder?

No. The Medeco parts in this range are rim-type and retrofit cylinders for residential-style hardware: 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. The Corbin Russwin 114-A03 is a commercial mortise cylinder for mortise locks and DL3000 deadlocks, so the two do not cross over.

19) Is this cylinder suitable for a residential deadbolt?

It is designated for commercial use, and it is built to thread into commercial mortise locks and DL3000 deadlocks rather than residential bored deadbolts. For a residential knob, handleset or deadbolt retrofit, Kaba Ilco's 1539 key-in-knob/lever universal cylinder or 1549 key-in-deadbolt cylinder are the deadbolt-function parts to look at instead.

20) Does the Corbin Russwin 114-A03 come with keys, or do I need to have it cut?

Two keys ship with each cylinder, cut to the keyway you order. It is intended to go straight into a new or existing master key system, so if it needs to work on an existing master, have your locksmith pin the core to your system rather than relying on the factory cut.

21) Is the Corbin Russwin 1080 mortise cylinder a substitute for a Sargent knob and lever cylinder?

No. The Kaba Ilco 1579 is a knob and lever cylinder made for Sargent hardware, which is a different cylinder format from a mortise cylinder. The Corbin Russwin 114-A03 is a 1-1/4 inch conventional mortise cylinder with the A03 Adams Rite MS cam, non-handed, offered in finishes including 605 Bright Brass, 613 Satin Bronze Oil-Rubbed, 626 Satin Chrome and 619 Satin Nickel. Match the cylinder format to the lock body you are working in.
