Corbin Russwin CR1080-134-A02-6-L4-626 – Frequently Asked Questions

1) Will a Corbin Russwin 1080 Series 1-3/4 inch mortise cylinder fit a Schlage L9000 mortise lock?
Yes, with the A02 straight cam. The 1080 Series 134-A02 is a 1-3/4 inch mortise cylinder built for all mortise locks and DL3000 deadlocks, and the description calls out Schlage L9000 mortise locks specifically as an A02 straight cam application. You still key it in a Corbin Russwin keyway, so the L9000 will be on a Corbin Russwin key system after the swap, not a Schlage one.
2) How do I know whether I need the A02 straight cam or a different cam for my mortise lock?
The cam is what drives the lock, so it has to match the lock body, not the door. A02 is the straight cam used on standard mortise lock applications including Schlage L9000. The 1080 platform also offers A01 cloverleaf, A03 for Adams Rite MS, A04 for DL4000, A05 for Adams Rite 4070, A06 Schlage cloverleaf, A07 for DL4100, A62 900 KRM straight, A92 and A93. Pull the old cylinder and match the cam shape and screw pattern before ordering.
3) Is this an interchangeable core cylinder, and can I rekey it without taking the lock apart?
It is a large format interchangeable core (LFIC) cylinder, so the core pulls with a control key and swaps in place. You do not have to remove the lock from the door to rekey the opening, which is why facilities with frequent tenant or staff turnover standardize on it. Note that the cylinder body itself is also catalogued as a conventional mortise cylinder for its 1-3/4 inch mortise housing.
4) What keyway do I order to match the rest of my Corbin Russwin master key system?
Order the keyway your existing system is built on. The 1080 cylinder is available in 84 keyways, including the 27, 57, 59, 67, 77 and 98 families with their A1/A2/B1/B2 variants, the 252, 60, 70, 97, 99, AR, BL, BR, D1, D2 and G keyways, H1 through H8, L1 through L4, and N1 through N28. If you are extending an existing system, the keyway and key bitting have to come from the same system records, otherwise the new cylinder will not operate on your master.
5) What is the closest alternative to the Corbin Russwin 1080 134-A02 mortise cylinder if the lock needs a rim cylinder instead?
The Corbin Russwin 1080 134-A02 is a conventional mortise cylinder, 1-3/4 inch long with an A02 straight cam, so it threads into a mortise lock case and will not serve a rim device. For a rim application, the Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and 2 keys, and the Schlage 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam. Check which tailpiece orientation the exit device requires before ordering either.
6) Which mortise cylinder should I use if the opening is an Adams Rite deadlock rather than a Schlage L9000?
The Corbin Russwin 1080 134-A02 carries an A02 straight cam and is intended for mortise locks and DL3000 deadlocks, including Schlage L9000 mortise locks. For Adams Rite hardware, the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder listed to a 1/2 inch minimum door thickness. Note that the Corbin Russwin 1080 platform also offers A03 Adams Rite MS and A05 Adams Rite 4070 cams if you prefer to stay in one key system.
7) I need a mortise cylinder on Schlage C keyway instead of a Corbin Russwin keyway. What are my options?
The Corbin Russwin 1080 134-A02 is offered across Corbin Russwin keyways including 27, 57, 59, 60, 67, 70, 77, 97 through 99, and the N-series, so it keys into a Corbin Russwin system. If the building is keyed to Schlage C, the Detex MC65 is a 6-pin mortise cylinder in the Schlage C keyway at 1-1/8 inch length; confirm your mortise case accepts that shorter length before substituting for the 1-3/4 inch Corbin Russwin.
8) Do I have to specify handing when ordering a 1080 mortise cylinder?
No. The cylinder is non-handed, so the same part works on a left or right hand door. Only the keyway, finish and cam need to be specified. That keeps stocking simple if you are carrying spares for a building with doors swinging both ways.
9) What finishes does the Corbin Russwin 1080 mortise cylinder come in to match existing trim?
Seven: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 619 satin nickel, 625 bright chrome and 626 satin chrome. For most commercial openings the cylinder collar is the only visible part, so match it to the lever or escutcheon finish already on the door, commonly 626 on institutional work.
10) What is the difference between this LFIC cylinder and a small format interchangeable core like a BEST 1C?
Different core footprints and different systems. The 1080 is large format interchangeable core in a 1-3/4 inch mortise housing, so the core is the Corbin Russwin LFIC shape and keys to a Corbin Russwin keyway. A BEST 1C Series 5-pin core is a small format core and will not drop into an LFIC housing. If your building is already on BEST small format, stay with cores like the 1C5 or the patented 1CDF 7-pin rather than mixing formats.
11) Is a 6-pin cylinder worth it over a 5-pin for a building with a large master key system?
For a multi-level master key system, yes. The 1080 uses a six-pin tumbler, which gives more key change capacity and more room for master, sub-master and grand master levels than a five-pin cylinder such as the Adams Rite 4036 or a Medeco 5-pin retrofit cylinder. On a small standalone building with a handful of doors, five pins is usually enough.
12) What do I order instead of the Corbin Russwin 1080 mortise cylinder for a key-in-lever or key-in-knob lockset?
The 1080 134-A02 is a mortise cylinder for mortise lock cases and DL3000 deadlocks and will not fit a key-in-lever chassis. For key-in-lever and key-in-knob work, the Kaba Ilco 1539 is a universal key-in-knob/lever cylinder, the 1579 is a knob and lever cylinder for Sargent, and the 1599 is a key-in-knob replacement cylinder. The Falcon A23161-05 G is a key-in-lever cylinder in the RU/T Series 6-pin G keyway supplied keyed different with 2 cut keys.
13) Is a BEST interchangeable core the same thing as the Corbin Russwin 1080 LFIC mortise cylinder?
No. The Corbin Russwin 1080 134-A02 is a complete 1-3/4 inch large format interchangeable core mortise cylinder with an A02 straight cam and 2 keys, so it includes the housing that threads into the lock. BEST cores such as the 1C5 standard 5-pin core, the Peaks 1CB 150 Series core, and the drill-resistant 1CDF 7-pin core are core-only items that drop into an existing BEST-prepped housing. They are not a substitute for a mortise cylinder housing.
14) For a deadbolt, can I use the Corbin Russwin 1080 134-A02 or is there a better cylinder?
The Corbin Russwin 1080 134-A02 suits mortise locks and DL3000 deadlocks with an A02 straight cam. For residential-style deadbolts and handlesets, the Kaba Ilco 1549 is a key-in-deadbolt cylinder, the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, and the Medeco 1075127 is a 5-pin lazy motion single cylinder for handlesets and deadbolts. The Medeco 1065140 covers Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders.
15) Is the Schlage 20-057 FSIC an equivalent swap for the Corbin Russwin 1080 LFIC mortise cylinder?
They are different formats and different mounting. The Corbin Russwin 1080 134-A02 is a large format interchangeable core conventional mortise cylinder, 1-3/4 inch, non-handed, with an A02 straight cam. The Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam and 2 keys, and the 20-057-C is an FSIC core in the C keyway with a 643E aged bronze finish. A rim cylinder does not thread into a mortise case, so the swap only works if the device itself is changing.
16) Does the 1080 mortise cylinder come with keys?
Two keys ship with the cylinder. If you are putting it into an existing master key system you will normally supply your own bitting and key stamping requirements when ordering, but as supplied it arrives with two cut keys so the opening can be turned over immediately.
17) Is the 1080 cylinder suitable for commercial and institutional use rather than residential doors?
It is a commercial cylinder, used on office buildings, schools, hospitals, government and municipal buildings, retail, multi-tenant residential and industrial facilities. For a house or a light residential handleset you would be looking at something like the Emtek CY4 cylinder or a Medeco rim type lazy motion cylinder instead of a 1-3/4 inch LFIC mortise cylinder.
18) If a door only needs the look of a cylinder and no keying, is there a cheaper option than the Corbin Russwin 1080?
The Corbin Russwin 1080 134-A02 is a functioning 6-pin LFIC mortise cylinder that ships with 2 keys for integration into a master key system. Where an inactive leaf or trim only needs to present a cylinder face, the BEST 12E Series dummy rim cylinder has a 1-5/32 inch diameter and provides no keyed function. Use the 1080 wherever the opening is actually locked and keyed.
