Corbin Russwin 3070-178-6 626 CT6D – Frequently Asked Questions

1) What does LFIC mean on a Corbin Russwin rim housing, and how is it different from a standard rim cylinder?
LFIC stands for Less Full Interchangeable Core. The 3070-178-6 housing is the shell only, built to receive a full interchangeable core rather than being pinned itself. That is what lets a facility rekey an opening in seconds with a control key instead of pulling and repinning the cylinder. A conventional rim cylinder, like the Schlage 20-021 or 20-022, is pinned internally and has to be repinned by a locksmith to change keys.
2) Will the 1-7/8 inch tailpiece on this Corbin Russwin rim housing work with my rim exit device?
The 3070-178-6 ships with the standard 1-7/8 inch tailpiece, which is the common length for rim exit device and rim cylinder applications. Measure from the back of the cylinder through the door and the device case: if your existing rim cylinder tailpiece is longer than 1-7/8 inches because of a thick door or a thick trim plate, you need the longer tailpiece version instead of this one.
3) Is this rim housing 6-pin or 7-pin, and does it have to match my existing Corbin Russwin cores?
It is a 6-pin configuration. The core you drop in has to be the same pin count and the same keyway family as the rest of your Corbin Russwin system, or it will not key into your master or grand master program. If your building standardized on 7-pin cores, this housing is not the one to order.
4) Can I use a BEST interchangeable core in the Corbin Russwin 3070-178-6 rim housing?
No. The 3070-178-6 CT6D is built around the Corbin Russwin interchangeable core program and ships with a Corbin Russwin temporary display core, so it should be finished with a Corbin Russwin operating core. BEST sells its own core line for BEST housings, including the 1C Series standard 5-pin core and the Peaks 1CB 150 Series interchangeable core, and those belong in BEST hardware. Order the core in the same brand program as the housing.
5) If I do not need interchangeable core keying on a rim exit device, what is a simpler rim cylinder to use?
A conventional pinned rim cylinder is the simpler route. The Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam supplied with two keys, and the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam. Those are keyed at the cylinder itself, so there is no separate core to order or control key to manage. The Corbin Russwin 3070-178-6 CT6D takes the other approach: it is a housing that accepts a full interchangeable core, which lets you re-key the opening by swapping the core with a control key instead of re-pinning.
6) What is the Schlage equivalent to the Corbin Russwin 3070-178-6 CT6D rim housing on an interchangeable core system?
The closest Schlage counterpart is the 20-057 6-pin FSIC rim cylinder with a convertible tailpiece cam. Both are rim cylinders built to receive an interchangeable core rather than a fixed pinned plug, so the core is keyed into the master key system separately. The difference is the core format and the keyway family: the Corbin Russwin 3070-178-6 CT6D is a Less Full Interchangeable Core housing shipped with a Corbin Russwin temporary display core, while the Schlage 20-057 is a full size interchangeable core cylinder in the Schlage program. Stay within the brand that matches the cores your facility already stocks, since the two core formats are not cross-compatible.
7) My opening is a narrow stile aluminum door with an MS deadlock, not a rim exit device. What should I order instead?
A rim housing is not the right part for that opening. For an Adams Rite MS1847 deadlock or deadlatch, the 4024 cylinder pull mounts with a trim plate and the 4025 is a five pin tumbler cylinder pull that mounts with through-screws. If the deadlock takes a mortise cylinder instead of a pull, the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder in the 4036 Series. The Corbin Russwin 3070-178-6 CT6D is configured with a 1-7/8 inch standard tailpiece for rim cylinder applications, which is a different prep entirely.
8) Is this a complete lock or just a replacement component?
Just the component. The 3070-178-6 CT6D is a replacement rim cylinder housing, not a lockset or an exit device. You install it into existing Corbin Russwin rim hardware, most often a rim exit device, and add the operating core separately.
9) What is the difference between the Corbin Russwin 3070-178-6 rim housing and a mortise cylinder like the Detex MC65?
They fit different locks. The 3070-178-6 CT6D is a rim housing with a 1-7/8 inch tailpiece, which drives a rim exit device or rim lock mounted on the face of the door. The Detex MC65 is a mortise cylinder with a Schlage C keyway, 1-1/8 inch length, 6-pin, which threads into a mortise lock body and turns a cam. Confirm which prep the door has before ordering, because the two are not interchangeable in the same lock.
10) I need a cylinder for a key-in-knob or key-in-lever lock. Is the 3070-178-6 the right part?
No. The 3070-178-6 CT6D is a rim housing and will not fit a knob or lever. For knob and lever cylinders, the Kaba Ilco 1539 Series is a universal key-in-knob and lever cylinder, the 1579 Series is a knob and lever cylinder for Sargent hardware, and the 1599 Series is a key-in-knob replacement cylinder. Falcon also offers the A23161-05 G key in lever cylinder, 6-pin G keyway, keyed different with two cut keys.
11) The temporary display core that comes with the 3070-178-6 is not an operating core. Is there a dummy rim cylinder I should use instead for a non-keyed opening?
If the opening never needs to be keyed, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter fills the hole without any keying function. The Corbin Russwin 3070-178-6 CT6D takes a different path: the CT6D temporary display core lets the housing be staged or mounted now and then finished with a permanent operating core once the keying program is cut, so it is the choice when the door will eventually be keyed into a master key system.
12) Would a Medeco rim cylinder work as a substitute for the Corbin Russwin 3070-178-6 on a rim exit device?
Not directly. The Medeco rim cylinders in this range are built for residential-style handleset and deadbolt hardware rather than commercial rim exit devices: the 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. The Corbin Russwin 3070-178-6 CT6D is a commercial rim housing with a 1-7/8 inch standard tailpiece sized for common rim exit device applications.
13) What is the difference between the Corbin Russwin 3070-178-6 CT6D and the Schlage 20-057-C?
The Schlage 20-057-C is a full size interchangeable core cylinder supplied with a C keyway in a 643E Aged Bronze finish, so it comes as a keyed core in the Schlage program. The Corbin Russwin 3070-178-6 CT6D is the housing side of the assembly, a 6-pin LFIC rim housing in 626 Satin Chrome shipped with a temporary display core, with the permanent Corbin Russwin core ordered separately to match your keying. Pick based on whether you need the housing, the core, or both.
14) Is the Corbin Russwin 3070-178-6 suitable for apartment and multi-tenant buildings, or is it strictly for large commercial?
It is a commercial-grade part, and it works anywhere the hardware standard is commercial, including multi-tenant residential and mixed-use buildings. The reason property managers use interchangeable core here is turnover: when a tenant moves out you pull the core with a control key and drop a new one in, rather than calling a locksmith to repin the cylinder on every unit.
15) If I want a high security core in an interchangeable core rim application instead of a standard core, what are my options?
Within the interchangeable core cylinder world, BEST offers the 1CDF drill resistant preferred patented interchangeable core in 7-pin brass, 150 Series, for openings that call for key control and drill resistance. That core belongs in BEST housings. The Corbin Russwin 3070-178-6 CT6D is a 6-pin LFIC rim housing that accepts a Corbin Russwin full interchangeable core, so any security upgrade on that opening comes from the Corbin Russwin core you pin into it.
