Corbin Russwin CR1080-134-A01-6-L4-626 – Frequently Asked Questions

1) What locks besides Schlage will this 1080 mortise cylinder fit?
The stated application is all mortise locks and DL3000 deadlocks. The limiting factor is the cam, not the cylinder: the A01 cloverleaf drives Schlage-pattern hubs. For other lock cases the 1080 platform offers A02 straight, A03 Adams Rite MS, A04 DL4000, A05 Adams Rite 4070, A06 Schlage cloverleaf, A07 DL4100, A62 900 KRM straight, A92 and A93. Pick the cam that matches the lock case you are putting it in.
2) What do I have to specify when ordering a Corbin Russwin 1080 mortise cylinder?
Four things: cam (A01 here, the Schlage cloverleaf), length (1-3/4 inch here), keyway, and finish. Keyway choices run across the full Corbin Russwin range including 27, 57, 59, 60, 67, 70, 77, 97, 98, 99, 252, 981-983, AR, BL, BR, D1-D2, G, H1-H8, L1-L4 and N1-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.
3) Can I add this cylinder to an existing Corbin Russwin master key system?
Yes, provided you order it in the keyway your system is built on. Specify the matching keyway from the 1080 range and the cylinder keys into the existing hierarchy. It is a 6-pin cylinder, which is what most commercial Corbin Russwin master systems are built around, and it ships with 2 keys.
4) Will this mortise cylinder fit a rim exit device?
No. This is a threaded mortise cylinder with a cloverleaf cam and it will not mount in a rim device, which needs a rim cylinder with a tailpiece. For a rim application look at the Schlage 20-021 rim cylinder with vertical tailpiece cam or the 20-022 with horizontal tailpiece cam, both 6-pin.
5) I need a mortise cylinder for an Adams Rite MS deadlock on an aluminum storefront. Is this the right one?
Not with the A01 cam. Adams Rite MS deadlocks need the A03 Adams Rite MS cam (or A05 for the 4070), which the 1080 platform offers as a separate configuration. Another route on a storefront is the Adams Rite 4036 Grade 1 mortise cylinder, which is built for that application and works down to a 1/2 inch minimum door thickness.
6) We run a BEST interchangeable core system. Is the Corbin Russwin 1080 134-A01 the right cylinder for us?
The 1080 134-A01 is a large format interchangeable core mortise cylinder built on Corbin Russwin keyways such as the 57, 59, 67, 77 and N sections. A facility keyed on BEST cores would instead use a BEST core such as the 1C 5-pin standard core, the 1CB Peaks 150 Series interchangeable core, or the 1CDF drill resistant 7-pin patented core in the 150 Series. The choice comes down to which keying system the rest of the building is already on.
7) What is another mortise cylinder option if the opening needs a keyed mortise cylinder but not a large format interchangeable core?
The Corbin Russwin 1080 134-A01 is a 1-3/4 inch mortise cylinder with an A01 cloverleaf cam, supplied with 2 keys, for all mortise locks and DL3000 deadlocks. If an interchangeable core platform is not wanted, the Detex MC65 is a mortise cylinder with a Schlage C keyway, 1-1/8 inch length, 6-pin. The MC65 is a fixed keyed cylinder in a single keyway, while the 1080 platform is offered across a wide keyway range including 27, 57, 59, 67, 77, 98 and the N-series sections.
8) The exit device on the door takes a rim cylinder, not a mortise cylinder. What should I order instead?
The Corbin Russwin 1080 134-A01 is a mortise cylinder for mortise locks and DL3000 deadlocks and will not thread into a rim device. For a rim application, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and 2 keys, and the Schlage 20-022 is the same rim cylinder with a horizontal tailpiece cam. Pick the tailpiece orientation the exit device chassis calls for.
9) Will the Corbin Russwin 1080 134-A01 work in an Adams Rite narrow stile deadlock?
The 1080 134-A01 ships with the A01 cloverleaf cam intended for Schlage L9000 mortise lock tailpieces, so it is not the cam for an Adams Rite MS deadlock. The Adams Rite 4036 is a Grade 1 five-pin mortise cylinder in the 4036 Series with a 1/2 inch minimum door thickness, which is the narrow stile path. Note that the 1080 platform also offers A03 Adams Rite MS and A05 Adams Rite 4070 cams if you want to stay on Corbin Russwin keying.
10) Do I need to order a left-hand or right-hand mortise cylinder?
No handing to specify. The 1080 mortise cylinder is non-handed and threads into the lock case the same way regardless of which way the door swings. Handing only matters on the lock body and trim, not the cylinder.
11) What is the difference between the Corbin Russwin 1080 134-A01 and a Schlage full size interchangeable core cylinder?
Both are interchangeable core products, but they are not the same format or keying family. The 1080 134-A01 is a 1-3/4 inch LFIC mortise cylinder with an A01 cloverleaf cam for mortise locks and DL3000 deadlocks, non-handed, with 2 keys. The Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam and 2 keys, and the 20-057-C is a full size interchangeable core in the C keyway, 643E aged bronze. Match the cylinder body type to the lock before matching the core.
12) I need to rekey a key-in-lever lockset, not a mortise lock. Is this cylinder the right part?
No. The Corbin Russwin 1080 134-A01 is a mortise cylinder for all mortise locks and DL3000 deadlocks. For a key-in-lever chassis, the Falcon A23161-05 G is a key-in-lever cylinder for the RU/T Series, 6-pin G keyway, keyed different, with 2 cut keys, and the Kaba Ilco 1539 Series is a universal key-in-knob and lever cylinder. For a key-in-knob replacement specifically, the Ilco 1599 is the corresponding part.
13) Is there a cylinder-and-pull assembly for a glass storefront door instead of a plain mortise cylinder?
The Corbin Russwin 1080 134-A01 is a cylinder only, sized 1-3/4 inch with an A01 cam. If the storefront door needs a pull integrated with the cylinder, the Adams Rite 4024 is a cylinder pull with trim plate mounting for MS1847 deadlock systems and the Adams Rite 4025 is a five pin tumbler cylinder pull with through-screws for the same MS1847 deadlock. For a wood door, the Adams Rite 4026 five pin tumbler cylinder pull is built for the 5017 wood door deadlock.
14) We are keying a residential-style deadbolt and handleset. Is the 1080 134-A01 a match?
The 1080 134-A01 is a commercial mortise cylinder for mortise locks and DL3000 deadlocks. Residential deadbolt and handleset retrofits generally take a rim type lazy motion cylinder instead, such as the Medeco 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the Medeco 1075127 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, or the Medeco 1065244 5-pin rim lazy motion cylinder with an Emtek tailpiece.
15) Is a 6-pin cylinder worth it over a 5-pin for a commercial building?
For commercial work, yes. Six pins give a much larger set of usable key combinations, which matters once you are building masters and sub-masters across a facility, and they add pick resistance. Five-pin cylinders like the BEST 1C5 standard core are fine for smaller systems, but a six-pin platform leaves room to expand.
16) Can I match the finish of this cylinder to the mortise lock trim already on my doors?
Seven finishes cover most commercial trim: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 619 satin nickel, 625 bright chrome and 626 satin chrome. 626 satin chrome is the most common commercial standard and the usual match for existing lever trim in that finish.
17) The door only needs the look of a keyed cylinder with no operation. What should I use instead?
The Corbin Russwin 1080 134-A01 is a functioning 6-pin LFIC mortise cylinder supplied with 2 keys. Where a non-operating cylinder is wanted for appearance or to fill a prep, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter is the corresponding part. Keep in mind the 12E is a rim format, so confirm the door prep before ordering.
