Corbin Russwin CR1080-134-A03-6-L4-626 – Frequently Asked Questions

1) Is this cylinder an interchangeable core or a conventional one-piece cylinder?
The 1080 is a large format interchangeable core (LFIC) housing, classified as a conventional mortise cylinder. The core pulls with a control key so you can rekey an opening by swapping cores rather than pinning the cylinder, which is how most facilities handle tenant turnover. It is not a small format (SFIC) housing, so a 7-pin SFIC core such as the BEST 1CDF will not drop into it.
2) Can I use this Corbin Russwin cylinder in a Schlage L9000 mortise lock?
Yes. The 134-A03 is built for Schlage L9000 mortise lock applications, and the A03 cam is the one those bodies take when you are converting the opening to a Corbin Russwin key system. It works across mortise locks generally and DL3000 deadlocks as well.
3) Do I have to specify a keyway when ordering, and can it match my existing Corbin Russwin keys?
Keyway is a required choice. There are 85 keyways to pick from, covering the 27, 57, 59, 67, 77, 98 and N-series families plus AR, BL, BR, D1, D2, G, H1 through H8 and L1 through L4. Pick the keyway already running in your building and the cylinder drops into the existing master key system. Pinning is 6-pin, which gives you the extra chamber for deeper masterkey levels.
4) I need a cylinder for an exit device, not a mortise lock. Is this the right part?
No. A mortise cylinder threads into a mortise lock body or a DL3000 deadlock; rim exit devices need a rim cylinder with a tailpiece cam. For that, look at the Schlage 20-021 rim cylinder with a vertical tailpiece cam or the 20-022 with a horizontal tailpiece cam, both 6-pin and supplied with two keys.
5) What is an alternative mortise cylinder for an Adams Rite MS deadlock if a Corbin Russwin keyway is not required?
The Corbin Russwin 1080 134-A03 is a 1-3/4 inch conventional mortise cylinder supplied with the A03 Adams Rite MS cam, so it drops into Adams Rite MS-series applications on a Corbin Russwin key system. If the job does not need to sit on a Corbin Russwin system, the Adams Rite 4036 mortise cylinder is a Grade 1 five-pin mortise cylinder from the 4036 Series, listed for a 1/2 inch minimum door thickness. The 1080 is six-pin, which matters if the opening must fold into a multi-level master key system.
6) Can a rim cylinder be used in place of a mortise cylinder on a mortise lock or DL3000 deadlock?
No. The Corbin Russwin 1080 134-A03 is a conventional mortise cylinder with a threaded body and an A03 cam, intended for all mortise locks and DL3000 deadlocks. Rim cylinders such as the Schlage 20-021 with a vertical tailpiece cam or the 20-022 with a horizontal tailpiece cam mount through the door behind a rim device and drive a tailpiece rather than threading into a mortise lock case, so they are not interchangeable with a mortise cylinder.
7) Is a Detex MC65 mortise cylinder the same thing as the Corbin Russwin 1080 134-A03?
They are both commercial mortise cylinders but not the same part. The Detex MC65 is a 1-1/8 inch six-pin mortise cylinder in the Schlage C keyway. The Corbin Russwin 1080 134-A03 is 1-3/4 inch long, carries the A03 Adams Rite MS cam, and is a large-format interchangeable core cylinder offered in Corbin Russwin keyways. Length and cam determine whether the cylinder reaches and drives the lock case, so the two are not drop-in swaps.
8) What should I use instead of the 1080 134-A03 for a key-in-lever or key-in-knob lockset?
The Corbin Russwin 1080 134-A03 is a mortise cylinder for mortise locks and DL3000 deadlocks and will not fit a cylindrical lockset. For key-in-lever and key-in-knob bodies, the Falcon A23161-05 G is a key-in-lever cylinder for the RU/T series in the six-pin G keyway, keyed different with 2 cut keys, and Kaba Ilco lists the 1539 key-in-knob/lever universal cylinder and the 1599 key-in-knob replacement cylinder. The Ilco 1579 is the knob and lever cylinder for Sargent locks.
9) Do I need to order a left-hand and right-hand version of this mortise cylinder?
No. The 1080 mortise cylinder is non-handed, so one part number covers left- and right-hand openings. For a property manager stocking spares, that means a single line item on the shelf for every door it fits.
10) What finishes does the Corbin Russwin 1080 mortise cylinder come in to match my 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. Match the number on your existing lever or escutcheon, 626 satin chrome and 613 oil-rubbed bronze being the two you see most on commercial openings.
11) What are my other options for a mortise cylinder on an Adams Rite MS deadlock?
Two routes. Staying with Corbin Russwin gives you the 1080 with the A03 cam and an LFIC core in your own keyway. If you are not tying into a Corbin Russwin system, the Adams Rite 4036 Series mortise cylinder is a Grade 1 five-pin unit listed for doors 1/2 inch minimum thickness. The Detex MC65 is another mortise cylinder option, 1-1/8 inch and 6-pin in Schlage C keyway, if your existing building keys are Schlage C.
12) We standardize on BEST interchangeable cores. Can a BEST core go into the Corbin Russwin 1080 134-A03?
No. The 1080 134-A03 is a Corbin Russwin large-format interchangeable core mortise cylinder, ordered in Corbin Russwin keyways, and it accepts Corbin Russwin cores. BEST cores are a separate system: the 1C5 is a standard five-pin cylinder core, the 1CB is a 150 Series Peaks interchangeable core, and the 1CDF is a drill-resistant patented seven-pin interchangeable core in the 150 Series. If a facility is standardized on BEST cores, the housing needs to be a BEST-compatible body rather than the Corbin Russwin 1080.
13) Does this cylinder come with keys, or do I have to order them separately?
Two cut keys ship with each cylinder, so the opening is operable as soon as it is installed. Additional keys are a separate order.
14) Is the Corbin Russwin 1080 cylinder suitable for high-traffic commercial and institutional doors?
It is a commercial-duty replacement part, used in office buildings, schools, hospitals, retail, government facilities, warehouses and multi-tenant residential. The 6-pin LFIC format is what makes it workable at facility scale: one keyway across the building, cores swapped at the door when a key goes missing.
15) Is there a non-keyed option if I only need to fill a cylinder hole?
The Corbin Russwin 1080 134-A03 is a fully keyed 6-pin mortise cylinder shipped with 2 keys, so it is not the part for a blank opening. For a hole that needs filling on a rim application, the BEST 12E Series dummy rim cylinder measures 1-5/32 inch in diameter and is non-functional by design. Note that it is a rim format, not a threaded mortise body.
