Corbin Russwin CR1080-112-A01-6-L4-626 – Frequently Asked Questions

1) Is a 1-1/2 inch mortise cylinder the right length for my door, or do I need a longer one?

The 1080 mortise cylinder is a 1-1/2 inch length, which is the standard mortise cylinder length for a 1-3/4 inch commercial door with a normal mortise lock body and a flat trim escutcheon. Cylinder length is set by how far the cylinder has to reach through the trim to seat in the lock case, not by door thickness alone, so thick decorative trim, heavy rose plates, or a door over 1-3/4 inches usually calls for a longer cylinder instead. Measure from the face of the trim to the cylinder threads in the lock body before you order.

2) What do I need to specify when ordering, and does it come with keys?

Two choices decide the part number: finish and keyway. Finish runs 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 619 satin nickel, and 626 satin chrome. Keyway is the long list, 90 of them, including the standard 27, 59, 60, 70, 77, 97, 98 and 99 families, the A1/A2/B1/B2 restricted variants, the D and H groups, and N1 through N28. Each cylinder ships with 2 keys. If the building is on an existing master key system, the keyway has to match what is already in service or the key will not enter.

3) Can I use this Corbin Russwin cylinder on locks other than a Schlage L9000?

Yes. The 1080 is listed for all mortise locks and DL3000 deadlocks, not just the L9000. The A01 cloverleaf cam is the common mortise cam profile that most mortise lock bodies and mortise deadlocks accept. The constraint is cam profile and cylinder length, not brand, so confirm the lock case you have takes a cloverleaf cam and a 1-1/2 inch cylinder.

4) My building is on a BEST interchangeable core system. Can I put this Corbin Russwin cylinder on those doors?

Only if you keep the systems separate. The 1080 is a Corbin Russwin LFIC housing that takes a Corbin Russwin core and a Corbin Russwin keyway, so a BEST core will not drop into it and your BEST control key will not pull it. If you are extending an existing BEST system, stay in that family with a core like the BEST 1C 5-pin standard core or the 1CB Peaks interchangeable core. Use the 1080 when the building is on, or moving to, Corbin Russwin keying.

5) I need a 6-pin mortise cylinder for a Schlage keyway. Is this the right part?

Not if you need a Schlage keyway. The 1080 runs Corbin Russwin keyways, and the Schlage connection here is the A01 cam profile, not the key section. For a 6-pin mortise cylinder cut on a Schlage C keyway, the Detex MC65 is a 1-1/8 inch commercial mortise cylinder in Schlage C. Note the length difference: the MC65 is 1-1/8 inch where the 1080 is 1-1/2 inch, so they are not a straight swap in the same prep.

6) What is the difference between a Corbin Russwin 1080 mortise cylinder and a Schlage 20-021 rim cylinder?

They mount in different lock bodies and are not interchangeable. The Corbin Russwin 1080 is a conventional mortise cylinder that threads into the cylinder hole of a mortise lock case and drives the lock through the A01 cloverleaf cam, and it is specified for all mortise locks and DL3000 deadlocks. The Schlage 20-021 is a rim cylinder, a 6-pin unit with a vertical tailpiece cam that mounts to the back of a rim exit device through the door face. If the opening has a rim exit device rather than a mortise case, the mortise cylinder will not fit it. Schlage also builds the 20-022 rim cylinder with a horizontal tailpiece cam for devices that want the tailpiece rotated the other way.

7) The opening is an aluminum storefront with an Adams Rite deadlock, not a mortise lock. What cylinder goes there?

Adams Rite builds cylinders for its own hardware. The 4036 is a five-pin mortise cylinder rated Grade 1 with a 1/2 inch minimum door thickness, sized for narrow stile aluminum. For an MS1847 deadlock or deadlatch, Adams Rite makes the 4024 cylinder pull with trim plate mounting and the 4025 five-pin cylinder pull with through-screws; the 4026 five-pin cylinder pull is for the 5017 wood door deadlock and deadlatch instead. The Corbin Russwin 1080 is intended for mortise lock cases and DL3000 deadlocks, so it is the wrong family for a narrow stile storefront deadlock.

8) What is the difference between an LFIC mortise cylinder and a standard fixed mortise cylinder?

An LFIC (large format interchangeable core) housing takes a removable core that comes out with a control key, so rekeying a door is a 30 second core swap with no tools and no pulling the lock apart. A fixed cylinder has to be pinned or replaced. The 1080 is the LFIC housing version with a 6-pin core, which is what you want if you manage a lot of doors and expect tenant turnover or key loss. For a single door that will never be rekeyed, a conventional fixed cylinder is simpler and there is nothing to gain from the core system.

9) Do I have to specify handing when ordering a Corbin Russwin 1080 mortise cylinder?

No. The 1080 mortise cylinder is non-handed, so the same part goes in a left hand or right hand door. The cam orientation is fixed by the A01 cloverleaf design and the lock body it drives. What you do have to specify is finish and keyway.

10) Can I order these keyed alike across a group of doors or set up on a master key system?

Yes, and that is what the 6-pin core and the keyway list are for. The 1080 is built to sit inside a designed master key system, so a facility can run grand master, master, and change keys through the same cylinders. The practical requirement is that every cylinder in the system shares a keyway family, which is why there are 90 keyway options to pick from, including restricted sections like the 27A1, 57B2 and 59D1 variants. Give your keying schedule when you order rather than buying keyed-different stock and pinning it later.

11) What looks like a mortise cylinder but will not work in a mortise lock?

A few things get ordered by mistake. The BEST 12E series dummy rim cylinder has a 1-5/32 inch diameter and is a dummy, so it takes no key and operates nothing. The Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065244 is a 5-pin lazy motion rim cylinder with an Emtek tailpiece, and the 1075127 is a 5-pin lazy motion rim cylinder for handlesets and deadbolts; lazy motion rim cylinders drive a tailpiece, not a cam. The Medeco 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder, and the Emtek CY4 is sold as a single cylinder for Emtek hardware. For a mortise lock case you want the threaded mortise cylinder with the correct cam, which on the Corbin Russwin 1080 is the A01 cloverleaf cam for Schlage L9000 mortise locks.

12) Can I use a BEST interchangeable core instead of the Corbin Russwin 1080 LFIC mortise cylinder?

Only if the housing is a BEST-style figure-eight core housing. A BEST 1C core is a standard 5-pin interchangeable core, and the BEST 1CB is a Peaks 150 series interchangeable core; those are cores that drop into a matching housing, not complete mortise cylinders with a cam. The Corbin Russwin 1080 is supplied as a complete 1-1/2 inch mortise cylinder with the A01 cloverleaf cam already on it, so it goes straight into the mortise case. If the goal is drill resistance and a patented key, BEST offers the 1CDF, a drill resistant patented 7-pin brass core in the 150 series.

13) What should I order if the lock is a knob or lever rather than a mortise case?

A mortise cylinder will not fit a key-in-knob or key-in-lever chassis. Kaba Ilco covers those with the 1539 series key-in-knob and lever universal cylinder, the 1599 key-in-knob replacement cylinder, and the 1579 knob and lever cylinder built for Sargent locks; the 1549 is the key-in-deadbolt version. Falcon offers the A23161-05 G, a 6-pin key-in-lever cylinder in the G keyway supplied keyed different with two cut keys. The Corbin Russwin 1080 is a mortise cylinder for mortise lock cases and DL3000 deadlocks, and it also ships with 2 keys.

14) I am standardizing cylinders across a portfolio of commercial buildings - what makes the Corbin Russwin 1080 different from the one-off replacement cylinders?

The 1080 is a commercial 6-pin large format interchangeable core mortise cylinder, non-handed, sold in a wide keyway range and six finishes, which is what lets one specification cover many doors and one master key system cover a facility. Most of the alternatives are tied to one lock: the Kaba Ilco 1579 is built for Sargent knob and lever locks, the Medeco 1065140 retrofits the Arrow JL interconnected lock and Emtek handlesets, and the Adams Rite 4024 and 4025 serve the MS1847 deadlock. Those solve a single opening rather than a fleet. The LFIC design also lets cores be swapped for rekeying without pulling the lock apart.

15) What finish should I order to match the rest of my door hardware?

Six finishes are offered on the 1080 mortise cylinder: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 619 satin nickel, and 626 satin chrome. Those are BHMA finish numbers, so the simplest way to match is to read the number off the existing lock or trim rather than eyeballing the color. Most commercial interiors are 626 satin chrome; 613 is the common choice on bronze entrances.

16) Is this a residential grade cylinder or is it built for commercial traffic?

Commercial. The 1080 mortise cylinder is a commercial replacement part, sold for offices, schools, healthcare, government buildings, retail, warehouses and multi-tenant residential. It is a replacement cylinder rather than a complete lock, so it goes into an existing mortise lock case that is already hung on the door.
