Corbin Russwin 3070-178-7 626 – Frequently Asked Questions

1) Does the Corbin Russwin 178-7 rim cylinder housing come with a core, or do I need to order one separately?
The 178-7 ships less core. It's an LFIC (less full interchangeable core) 7-pin rim housing, so you supply the interchangeable core keyed into your existing system. What does come in the box is the mounting hardware: standard rosette and compression spring, break-off screws, and a back plate. If you're a locksmith pulling this for a job, plan on a 7-pin small format core to match the housing.
2) What is the 1-7/8 inch tailpiece on the Corbin Russwin 178-7 for, and will it reach my exit device?
The 1-7/8 inch horizontal tailpiece is what drives the exit device mechanism from behind the door face. Tailpiece length has to match the depth of the device it operates, so the 178-7 is sized for Corbin Russwin 3000 Series exit devices and exit device trim. Rim cylinders come in horizontal and vertical cam configurations and they are not interchangeable, so confirm your device takes a horizontal tailpiece before you order this one.
3) Why choose a 7-pin LFIC housing over a standard keyed rim cylinder for an exit device?
It comes down to who controls the keys. A conventional rim cylinder is rekeyed by taking it apart at the bench. The 178-7 is a 7-pin LFIC housing, so the core drops out with a control key and a new one goes in, in seconds, without pulling the device apart. For an institution or MRO group running masterkeying across a campus, that's the difference between a locksmith trip per door and a core swap. If you don't run an interchangeable core system, a fixed rim cylinder like the Schlage 20-022 with a horizontal tailpiece cam is the simpler choice.
4) Is the Corbin Russwin 178-7 a straight replacement for a damaged cylinder housing on an existing 3000 Series exit device?
That's exactly what it is for. The 178-7 is a replacement part for Corbin Russwin 3000 Series exit devices and exit device trim, non-handed, and it arrives with the rosette, compression spring, break-off screws and back plate, so you're not chasing loose mounting parts. You supply the 7-pin interchangeable core. Match the finish to the device trim already on the door from the ten BHMA finishes offered.
5) Difference between the Corbin Russwin 178-7 LFIC rim housing and a Schlage 20-057 FSIC rim cylinder?
Both are interchangeable core rim cylinders for exit device applications, but they take different core sizes. The Corbin Russwin 178-7 is an LFIC rim housing, meaning it accepts a large format interchangeable core in a 7-pin configuration and ships less core. The Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam and 2 keys. A core is not portable between the two formats, so the choice follows whatever core format the facility already keys: an LFIC system takes the 178-7 housing, an FSIC system takes the 20-057. Schlage also lists the 20-057-C as a full size interchangeable core cylinder in C keyway, 643E aged bronze finish, if the core itself is what is being replaced rather than the housing.
6) What is the closest Schlage equivalent to the Corbin Russwin 178-7 rim cylinder housing with a horizontal tailpiece?
The Schlage Commercial 20-022 is a 6-pin rim cylinder with a horizontal tailpiece cam supplied with 2 keys, which is the same horizontal-tailpiece rim configuration the Corbin Russwin 178-7 uses with its 1-7/8 inch horizontal tailpiece. The difference that decides the order is the core: the 178-7 is an LFIC rim housing supplied less core in a 7-pin format, so it takes a small format interchangeable core keyed into an existing system, while the 20-022 is a conventional 6-pin cylinder that arrives keyed with its own keys. If the building is on an interchangeable core key system, the 178-7 keeps the openings on that system; if there is no IC system to match, the 20-022 is a complete keyed cylinder out of the box.
7) My exit device needs a vertical tailpiece, not horizontal. What rim cylinder should I use instead of the Corbin Russwin 178-7?
The Corbin Russwin 178-7 is supplied with a 1-7/8 inch horizontal tailpiece and will not engage a device that expects a vertical tailpiece. The Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam supplied with 2 keys, which matches that orientation directly. A third option when the orientation on the device is uncertain or the same part number has to cover both is the Schlage 20-057, a 6-pin FSIC rim cylinder with a convertible tailpiece cam. Confirm the tailpiece orientation the exit device chassis calls for before ordering, since orientation is the one dimension that decides whether the cylinder turns the mechanism.
8) Will a Corbin Russwin 178-7 rim cylinder work in an aluminum storefront door with an Adams Rite deadlock?
The Corbin Russwin 178-7 is a rim cylinder housing for exit devices and exit device trim, which is a surface-applied rim prep rather than the narrow stile prep an aluminum storefront deadlock uses. For an Adams Rite MS1847 deadlock or deadlatch, Adams Rite lists the 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws, both specified for use with the MS1847. For a mortise cylinder in that same narrow stile world, the Adams Rite 4036 is a five-pin mortise cylinder listed as Grade 1 with a 1/2 inch minimum door thickness. Glass front and storefront openings almost always fall to the Adams Rite parts rather than a rim housing.
9) Is a Medeco lazy motion rim cylinder a substitute for the Corbin Russwin 178-7?
They are both called rim cylinders but they drive different hardware. 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 type cylinder with an Emtek tailpiece, and the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. Lazy motion rim cylinders are built for deadbolt and handleset backsides, with the tailpiece matched to that specific lock brand. The Corbin Russwin 178-7 is an LFIC rim housing for exit devices and exit device trim, supplied less core with a 1-7/8 inch horizontal tailpiece. Order by what the tailpiece has to turn, not by the words rim cylinder alone.
10) Do I need to order a left hand or right hand version of the Corbin Russwin 178-7 cylinder housing?
No handing to specify. The 178-7 rim cylinder housing is non-handed, so the same part goes on a left hand or right hand opening. For a property manager or facility stocking spares, that means one part number covers every door in the building instead of two.
11) What do the break-off screws on this Corbin Russwin rim cylinder housing do, and can I remove the housing later?
The break-off screws shear off once tightened, which is the point: nobody can back the housing off the door from the outside. That's a vandal and tamper measure for high-traffic or security-sensitive openings. Practically, it means you plan for it at install. Because the housing is LFIC, routine rekeying is done by pulling the core with a control key, not by removing the housing, so the sheared screws don't get in the way of normal key changes.
12) Can I use the Corbin Russwin 178-7 rim housing on a mortise lock or a deadbolt?
No. It's a rim housing, which mounts through the door and drives a surface mounted device from behind. A mortise lock takes a threaded mortise cylinder with a cam, which is a completely different body. For mortise work look at a mortise cylinder such as the Detex MC65 or the Adams Rite 4036; for a key-in-knob or lever replacement, a cylinder like the Kaba Ilco 1599 is the right family.
13) Is a BEST 1CDF or 1CB core what goes into the Corbin Russwin 178-7 housing?
The Corbin Russwin 178-7 is an LFIC rim housing supplied less core, so a core is exactly what it needs to become a working cylinder. BEST lists the 1CDF as a drill resistant patented interchangeable core in 7-pin brass, 150 series, and the 1CB Peaks as a 150 series interchangeable core cylinder. Both are interchangeable core products in the large format family the 178-7 housing is built around, and the 1CDF matches the 178-7 pinning at 7 pins. Verify with your key system supplier that the core keyway and control key match the system the building is already on before pairing them, since the housing carries no keying of its own.
14) I need a non-functioning rim cylinder to fill an unused exit device prep. Is the Corbin Russwin 178-7 the right part?
No. The Corbin Russwin 178-7 is a working LFIC rim cylinder housing meant to take a keyed interchangeable core and operate exit devices and exit device trim. For an opening where the prep needs to be filled and matched visually but no key operation is wanted, the BEST 12E series dummy rim cylinder with a 1-5/32 inch diameter is the part built for that job. Use the 178-7 where the door has to be keyed and the 12E dummy where it does not.
15) What do I order if the opening is a wood door deadlock rather than an exit device?
The Corbin Russwin 178-7 rim cylinder housing is specified for exit devices and exit device trim. For a wood door deadlock or deadlatch, Adams Rite lists the 4026 five pin tumbler cylinder pull, specified for use with the Adams Rite 5017 wood door deadlock and deadlatch. Match the cylinder to the lock body already in the door: a rim housing engages an exit device chassis through its tailpiece and will not drive a deadlock designed for a cylinder pull.
16) I need to rekey a lever lock, not an exit device. Is the Corbin Russwin 178-7 the cylinder for that?
No. The 178-7 is a rim cylinder housing for exit devices and exit device trim, and it engages the device through a 1-7/8 inch horizontal tailpiece rather than seating inside a lever chassis. For key-in-lever and key-in-knob work the comparable parts are Kaba Ilco's 1539 series key-in-knob and lever universal cylinder, the 1599 key-in-knob replacement cylinder, and the 1579 knob and lever cylinder for Sargent. Falcon also lists the A23161-05 G key in lever cylinder, an RU/T series 6-pin G keyway supplied keyed different with 2 cut keys. Pick by the lock chassis brand you are retrofitting, since knob and lever cylinders are chassis-specific in a way a rim cylinder is not.
17) Corbin Russwin 178-7 versus a mortise cylinder like the Detex MC65 for an exit device?
Rim and mortise are two different preps and are not interchangeable. The Detex MC65 is a 1-1/8 inch 6-pin commercial grade mortise cylinder in Schlage C keyway, which threads into a mortise-prepped device or lock body. The Corbin Russwin 178-7 is a rim cylinder housing that mounts through the door with break-off screws and drives the device by tailpiece, furnished with a rosette, compression spring, and back plate. Check whether the exit device or trim calls for a rim cylinder or a threaded mortise cylinder before ordering, since the wrong prep cannot be adapted at the door.
18) What finishes does the Corbin Russwin 178-7 rim cylinder housing come in?
Ten finishes, all standard BHMA codes so they match the rest of the trim on the opening: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 619 satin nickel, 622 flat black, 625 bright chrome, 626 satin chrome, 629 bright stainless steel and 630 satin stainless steel. On commercial exit device work 626 satin chrome and 630 satin stainless are the two that most often match existing hardware.
19) What cylinder do I use for an Emtek or Arrow interconnected lock instead of the Corbin Russwin 178-7?
The 178-7 is a rim housing for exit devices and exit device trim and does not fit residential-style handleset or interconnected lock chassis. Emtek lists the CY4 cylinder as a parts item for its own hardware, and Medeco lists the 1065140 as a 5-pin retrofit cylinder for the Arrow JL interconnected lock and for Emtek handleset and deadbolt outside cylinder positions. Those are the parts to order when the opening is a handleset or interconnected lock rather than a commercial exit device.
20) For standardizing cylinders across a campus, how does the Corbin Russwin 178-7 compare to the alternatives on finish range?
The Corbin Russwin 178-7 rim cylinder housing is offered across ten finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 619 satin nickel, 622 flat black, 625 bright chrome, 626 satin chrome, 629 bright stainless steel, and 630 satin stainless steel. That range lets a facility match cylinder trim to whatever finish the existing lever and exit hardware already carries. Among the comparable interchangeable core options, the Schlage 20-057-C is listed in 643E aged bronze, which is a different finish family and will read differently alongside chrome or stainless trim. The 178-7 is also non-handed, so one part number covers both hands across a campus.
