Corbin Russwin CR1070-114-A01-6 626 – Frequently Asked Questions

1) What does the A01 cloverleaf cam on a Corbin Russwin mortise cylinder actually drive?
The A01 cloverleaf cam is the standard Corbin Russwin mortise cam, and it works with all Corbin Russwin mortise locks and DL3000 deadlocks. The cam is the tab on the back of the cylinder that turns the lock case hub, so it has to match the lock case you are installing into. If your lock case calls for a straight cam instead, that is a different cam suffix, not this one.
2) Will a 1-1/4 inch mortise cylinder stick out too far or sit too deep on my door?
The 114-A01 housing is 1-1/4 inch (32mm) long, which is the standard mortise cylinder length for typical commercial door and trim thicknesses. Cylinder length has to be set so the face sits flush or nearly flush with the escutcheon or trim ring. If your trim is thicker than usual and the cylinder sits proud, you need a longer housing in the same series, not spacer rings.
3) I need a rim cylinder for an exit device, not a mortise cylinder. Is this the right part?
No. The 114-A01 is a mortise housing with a cloverleaf cam, threaded into a mortise lock case or a DL3000 deadlock. A rim device takes a rim cylinder with a tailpiece. For that, look at the Schlage 20-021 6-pin rim cylinder with vertical tailpiece cam or the 20-022 with horizontal tailpiece cam, or the Schlage 20-057 FSIC rim cylinder if you want interchangeable core on the rim side.
4) My existing mortise cylinder is a conventional keyed cylinder. Is the 114-A01 a direct swap?
Physically it threads into the same mortise prep at 1-1/4 inch length with the A01 cloverleaf cam, which is the standard Corbin Russwin mortise cam. What changes is the key system: this is a housing for an interchangeable core, so it will not work with your existing conventional key unless you also order a core cut to that keyway. If you want a straight conventional replacement cylinder in a fixed length, the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in Schlage C keyway.
5) We have an aluminum storefront with an Adams Rite MS1847 deadlock. Is the Corbin Russwin 1070 the right cylinder?
No. The 1070 housing is cammed for all mortise locks and DL3000 deadlocks, not for narrow stile storefront deadlocks. For an MS1847, the Adams Rite 4024 cylinder pull mounts with a trim plate and the 4025 is a five pin tumbler cylinder pull with through-screws, both built for that deadlock. For a wood door with the Adams Rite 5017 deadlock, the 4026 five pin cylinder pull is the matching part.
6) What is the difference between the Corbin Russwin 1070 mortise housing and the Detex MC65 mortise cylinder?
Both are mortise cylinders, but they are built for different key systems. The Corbin Russwin 1070 is a housing-only component in the Conventional Mortise classification that accepts a 6-pin interchangeable core, so the core can be pulled and swapped without taking the cylinder out of the lock. The Detex MC65 is a complete 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway, rekeyed by repinning rather than by core exchange. The Corbin Russwin housing is 1-1/4 inch long, so if the mortise lock cavity was sized around a 1-1/8 inch cylinder you need to confirm projection before swapping between the two.
7) I need an interchangeable core cylinder but the door takes a rim device, not a mortise lock. What should I use instead?
The Corbin Russwin 1070 is a mortise housing with an A01 cloverleaf cam, sized for all mortise locks and DL3000 deadlocks, and it will not mount to a rim exit device. For a rim application with interchangeable core, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam, and the 20-057-C is the full size interchangeable core version in the C keyway. Those thread into a rim device housing rather than into a mortise lock body.
8) Can I use a BEST interchangeable core in the Corbin Russwin 1070 housing?
No. The 1070 is a Corbin Russwin housing that accepts Corbin Russwin 6-pin interchangeable cores and supports their master key, grand master, and construction keying arrangements. BEST cores such as the 1CB 150 Series interchangeable core or the 1CDF drill resistant 7-pin core are built for BEST housings and figure-eight core prep, and are a separate keying platform. Pick the core family that matches the housing brand and the building's existing key system.
9) Do I have to specify handing when ordering this Corbin Russwin mortise cylinder housing?
No handing to specify. The 114-A01 housing is non-handed, so the same part goes into left and right hand openings. For a property manager stocking spares across a building, that means one part number covers every mortise opening regardless of swing.
10) Can I rekey this without pulling the lock off the door?
That is the point of the interchangeable core setup. With the CR1070 housing, a control key pulls the core out of the housing and a new core drops in, so the lock case and trim stay on the door. Non-technical staff can do the swap, which is why facilities with high turnover run IC rather than conventional cylinders.
11) Can I use temporary construction cores in these housings during a job and swap them at turnover?
Yes. The CR1070 housings take Corbin Russwin temporary construction cores, so the trades run on a construction key during the build and the permanent cores go in at handover. Special construction master keying is available but has to be planned when the key system is first set up, not added later.
12) Will this housing work in a master keyed or grand master keyed system?
It will. The 114-A01 is a conventional mortise classification housing and supports the full range of Corbin Russwin keying, including master key, grand master and construction keying. Concealed Key Control is available across Corbin Russwin cores if you need restricted key duplication on the system.
13) Can I step up to 7-pin or higher security cores later in the same housings?
Yes. The CR1070 housing takes standard 6-pin interchangeable cores, and cores are also offered in 7-pin, security and Pyramid configurations. So the housing you install now does not have to be replaced if the facility tightens key control down the road, only the cores.
14) What are my interchangeable core alternatives if I am not standardized on Corbin Russwin?
If the building is not already on a Corbin Russwin key system, the housing and core have to match the system you run, so switching brands means switching both. BEST is the other common IC platform we carry: the 1C 5-pin standard core, the Peaks 1CB 150 Series core, and the drill resistant 1CDF 7-pin patented core. Schlage's full size interchangeable core route is the 20-057-C in C keyway. Pick the platform first, then the housings.
15) Is the Adams Rite 4036 mortise cylinder a substitute for the Corbin Russwin 1070 housing?
They serve different openings. The Adams Rite 4036 is a Grade 1 five-pin mortise cylinder intended for narrow stile aluminum hardware, with a door thickness minimum of 1/2 inch. The Corbin Russwin 1070 is a 1-1/4 inch housing that takes a removable 6-pin interchangeable core and carries the A01 cloverleaf cam for mortise locks and DL3000 deadlocks. If the building is keyed on a Corbin Russwin IC system, the 4036 will not accept those cores.
16) What do I order if the cylinder goes in a knob or lever instead of a mortise lock?
A mortise housing like the Corbin Russwin 1070, with its threaded body and A01 cloverleaf cam, only fits mortise lock bodies and DL3000 deadlocks. For key-in-knob or key-in-lever bodies, the Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the 1579 is the knob and lever cylinder for Sargent, and the Falcon A23161-05 G is a key-in-lever cylinder with a 6-pin G keyway supplied with two cut keys. Match the cylinder to the lock chassis brand.
17) What is the simplest option if I just need a mortise cylinder and do not run an interchangeable core system?
The Corbin Russwin 1070 is a housing built around IC convenience, letting staff rekey by swapping the core without pulling hardware off the door. If the property has no IC program, a fixed mortise cylinder is simpler to stock: the Detex MC65 is a 6-pin commercial grade mortise cylinder in the Schlage C keyway at 1-1/8 inch, and the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder. Both are rekeyed by repinning rather than by core exchange, so confirm your locksmith supports that workflow.
18) I need a replacement cylinder for a residential deadbolt or handleset. Does the Corbin Russwin 1070 fit?
It does not. The 1070 is a commercial mortise housing for mortise locks and DL3000 deadlocks. Residential deadbolts and handlesets use rim-type lazy motion cylinders instead: the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1075127 is a 5-pin rim lazy motion single cylinder for handlesets and deadbolts, and the 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece.
19) How does the Corbin Russwin 1070 compare with the Schlage 20-021 and 20-022 rim cylinders for keying a building?
The Schlage 20-021 and 20-022 are 6-pin rim cylinders supplied with two keys, differing from each other in tailpiece cam orientation, vertical on the 20-021 and horizontal on the 20-022. The Corbin Russwin 1070 is a mortise housing, non-handed, supplied with two keys, and uses the A01 cloverleaf cam for mortise lock bodies. A mixed building often needs both families: rim cylinders at the exit devices and mortise housings at the mortise locks, keyed alike within one system.
20) What finishes does the Corbin Russwin 114-A01 mortise housing come in?
Ten finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 613E dark oxidized satin bronze equivalent, 619 satin nickel, 625 bright chrome, 626 satin chrome, 630 satin stainless steel, and BSP black suede powder coat. Match the cylinder to the lock trim already on the opening; 626 satin chrome and 630 are the usual commercial defaults.
21) Will a BEST 12E dummy rim cylinder work as a blank filler in a Corbin Russwin mortise prep?
No. The BEST 12E is a dummy rim cylinder with a 1-5/32 inch diameter, made for rim prep on a rim device. The Corbin Russwin 1070 is a 1-1/4 inch threaded mortise housing with the A01 cloverleaf cam driving the mortise lock hub. Rim and mortise preps are not interchangeable, so a dummy for a mortise cavity has to be a mortise-bodied part.
