Corbin Russwin CR1080-134-A05-6-L4-626 – Frequently Asked Questions

1) What cam do I order on a Corbin Russwin 1080 mortise cylinder for a Schlage L9000 versus other lock bodies?

For a Schlage L9000 mortise lock, the A05 Adams Rite 4070 cam is the one specified. The 1080 platform also offers Cloverleaf (A01), Straight (A02), Adams Rite MS (A03), DL4000 Series (A04), Schlage Cloverleaf (A06), DL4100 (A07) and 900 KRM Straight (A62). The cam is what makes the cylinder throw the lock, so pick it off the lock body you are putting it in, not off the door.

2) Is the 1-3/4 inch length the right mortise cylinder size for my door?

Cylinder length is set by the lock body and how far the cylinder has to reach through the trim, not by door thickness. The 1080 here is the 1-3/4 inch (44mm) length, which is the longer size used where trim or a thicker door leaf sets the cylinder back from the lock case. If your existing cylinder measures shorter, order the matching shorter 1080 length so the cam sits at the correct depth in the lock.

3) Can I rekey this Corbin Russwin cylinder without pulling it out of the lock?

Yes. This is a 6-pin large format interchangeable core cylinder, so the core pulls with a control key and a replacement core drops in. No disassembly of the lock body and no pinning kit needed at the door, which is why schools, hospitals and multi-tenant buildings standardize on LFIC for turnover.

4) What locks will this Corbin Russwin 1080 mortise cylinder fit?

The 1080 is specified for all mortise locks and DL3000 deadlocks. It is a conventional mortise cylinder, so it threads into any standard mortise cylinder prep; what decides whether it actually operates your lock is the cam, and this one carries the A05 Adams Rite 4070 cam.

5) Which keyway do I order so this cylinder works on our existing master key system?

Order the keyway your system is already cut to. The 1080 is offered across 85 keyways, including the 27, 57, 59, 67, 77, 97, 98 and 99 families, the 252, 60 and 70 keyways, AR, BL, BR, G, D1/D2, H1 through H8, L1 through L4, and N1 through N28. A locksmith reading your existing key bow or your keying schedule can tell you which one to specify; a mismatched keyway will not accept your master.

6) What is the difference between the Corbin Russwin 1080 mortise cylinder with the A05 cam and the Adams Rite 4036 mortise cylinder?

Both are mortise cylinders, but they come from different keying platforms. The Corbin Russwin 1080 with the A05 Adams Rite 4070 cam is a 1-3/4 inch conventional mortise cylinder used with all mortise locks and DL3000 deadlocks, supplied with 2 keys. The Adams Rite 4036 is a Grade 1 mortise cylinder from the 4036 series with a five-pin plug and a 1/2 inch minimum door thickness. If the opening is already standardized on a Corbin Russwin key system, the 1080 keeps the cylinder inside that system; if the job is a standalone Adams Rite installation, the 4036 is the native part.

7) I need a cylinder for an Adams Rite MS1847 deadlock on an aluminum storefront - will the Corbin Russwin 134-A05 work?

The Corbin Russwin 1080 134-A05 is built around the A05 Adams Rite 4070 cam, which targets Adams Rite 4070 hardware and Schlage L9000 mortise locks, not the MS1847. For an MS1847 opening where the cylinder also serves as the pull, the Adams Rite 4024 cylinder pull mounts with a trim plate and the Adams Rite 4025 is a five pin tumbler cylinder pull that mounts with through-screws; both are designed for use with the Adams Rite MS1847 deadlock/deadlatch. On a wood door the Adams Rite 4026 five pin cylinder pull is the matching part for the 5017 wood door deadlock/deadlatch.

8) My exit device needs a rim cylinder, not a mortise cylinder - what should I order instead of the 1080 134-A05?

The Corbin Russwin 1080 134-A05 is a conventional mortise cylinder that threads into a mortise lock body, so it will not serve a rim device. For rim applications the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the Schlage 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam, each supplied with 2 keys. Pick the tailpiece orientation that matches the device chassis.

9) Our building is standardized on a Schlage full size interchangeable core system - is the Corbin Russwin 1080 LFIC an equivalent?

They are both large/full size interchangeable core products but they are not the same core family. The Corbin Russwin 1080 134-A05 is a 6-pin LFIC mortise cylinder that accepts Corbin Russwin cores and is offered across keyways from 27 and 57 through the N series and letter keyways such as D1, G, H1 and L1. On a Schlage FSIC system, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam and the 20-057-C is a full size interchangeable core in the C keyway, 643E Aged Bronze. Mixing core families means keeping two key systems, so match the core to the system already in the facility.

10) I need a mortise cylinder for a Schlage C keyway opening - is there an alternative to the Corbin Russwin 1080?

The Corbin Russwin 1080 134-A05 is offered in Corbin Russwin keyways such as 27, 57, 59, 67, 77 and the N series, so it is the right choice when the site keys to Corbin Russwin. For an opening on a Schlage C keyway, the Detex MC65 is a commercial grade 6-pin mortise cylinder with a Schlage C keyway and a 1-1/8 inch length, versus the 1-3/4 inch length of the 1080 - confirm the lock body's cylinder depth before swapping, since the two lengths are not interchangeable.

11) Does the Corbin Russwin 1080 cylinder have to be ordered left or right hand?

No handing to specify. The 1080 mortise cylinder is non-handed, so one part number covers left and right hand openings. For a property manager stocking spares across a building, that means a single cylinder in one keyway and finish covers every door taking this cam.

12) What is the difference between this LFIC mortise cylinder and a rim cylinder like the Schlage 20-021?

Different prep entirely. The 1080 is a threaded mortise cylinder that screws into a mortise lock case or a DL3000 deadlock. A rim cylinder such as the Schlage 20-021 (6-pin, vertical tailpiece cam) or the 20-022 (horizontal tailpiece) mounts through the door and drives a surface-applied rim device with a tailpiece, not a cam. They are not interchangeable, so check whether the lock body sits inside the door edge (mortise) or on the face of the door (rim) before ordering.

13) What is the difference between the Corbin Russwin 1080 LFIC cylinder and a BEST interchangeable core?

The Corbin Russwin 1080 134-A05 is a complete 1-3/4 inch mortise cylinder housing with the A05 Adams Rite 4070 cam already fitted, supplied with 2 keys. The BEST 1C5 is a standard 5-pin cylinder core on its own, the 1CB is a Peaks 150 series interchangeable core, and the 1CDF is a drill resistant patented 7-pin brass core in the 150 series - those are cores that drop into a housing you already have, not a cam-equipped mortise cylinder. Order the 1080 when you need the housing and cam; order a BEST core when the mortise housing is already in the door and keyed to a BEST system.

14) Can I use the Corbin Russwin 1080 134-A05 to rekey a key-in-lever or key-in-knob lockset?

No. The 1080 134-A05 is a mortise cylinder for mortise lock bodies and DL3000 deadlocks. For a key-in-lever chassis, 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. The Kaba Ilco 1539 is a universal key-in-knob/lever cylinder and the 1599 is a key-in-knob replacement cylinder; the 1579 covers Sargent knob and lever chassis.

15) Can the Corbin Russwin 1080 134-A05 replace the outside cylinder on a residential deadbolt or handleset?

It is not the right part for that. The 1080 134-A05 is a commercial mortise cylinder for mortise locks and DL3000 deadlocks. Residential deadbolt and handleset retrofits use rim-type lazy motion cylinders: the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, and the 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece. For an Arrow JL interconnected lock or an Emtek handleset outside cylinder, the Medeco 1065140 is the 5-pin retrofit.

16) I have an Emtek door set and need a replacement cylinder - is the Corbin Russwin 1080 the match?

No. The 1080 134-A05 is a 1-3/4 inch commercial mortise cylinder cammed for Adams Rite 4070 and Schlage L9000 mortise locks. For an Emtek set, the Emtek CY4 cylinder is the brand's own replacement part, and the Medeco 1065244 is a 5-pin rim lazy motion cylinder supplied with an Emtek tailpiece if you are moving that opening onto a Medeco key system.

17) What finishes does the Corbin Russwin 1080 mortise cylinder come in to match our existing trim?

Seven finishes: 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 ring is 626 satin chrome or 630-family stainless trim, so 626 is the usual match on new work.

18) Is this cylinder suitable for a high traffic commercial building or is it residential grade?

Commercial. The 1080 mortise cylinder is classified for commercial use and is the cylinder Corbin Russwin puts on mortise lock openings in offices, schools, hospitals, government buildings and multi-tenant properties. It is sold as a replacement part, so it is the standard item for swapping out a failed or compromised cylinder without replacing the lock body.

19) Is there a non-keyed version of the 1080 mortise cylinder for a door that only needs the look of a cylinder?

The Corbin Russwin 1080 134-A05 is a keyed 6-pin LFIC cylinder supplied with 2 keys, so every one operates a lock. Where an opening needs the appearance of a cylinder without key function, the BEST 12E series dummy rim cylinder with a 1-5/32 inch diameter fills the prep instead - note that it is a rim-format part, not a mortise-threaded one.
