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

1) I have Schlage exit devices, not Corbin Russwin. Is the 178 rim housing the right cylinder?

Cylinders are keyed to a manufacturer's system, and the 178 is a 6-pin Corbin Russwin 3000 Series LFIC housing, so it belongs on a Corbin Russwin core program. For Schlage openings, ZenSupply carries the Schlage Commercial 20-022 rim cylinder with a horizontal tailpiece cam, the 20-021 with a vertical tailpiece cam, and the 20-057 6-pin FSIC rim cylinder if you run Schlage full size interchangeable cores. Match the tailpiece orientation to what your device needs, the same check you would make on the Corbin part.

2) Our building is standardized on BEST interchangeable cores. Can we use the Corbin Russwin 178 housing?

No. BEST small format cores and Corbin Russwin large format cores are different core geometries, and the 178 is a Corbin Russwin LFIC housing. If your facility runs BEST, stay in that program with cores like the BEST 1C Series 5-pin core or the 1CB 150 Series interchangeable core, and for a rim application the BEST 12E Series rim cylinder with a 1-5/32 inch diameter. Mixing core platforms on one building means two control keys and two key systems to administer, which is the thing an interchangeable core program exists to avoid.

3) Can I use the Corbin Russwin 178 rim housing on an aluminum storefront door with an Adams Rite deadlatch?

Not the right part. The 178 is a rim housing for exit devices and exit device trim, and a narrow stile storefront deadlatch takes a mortise cylinder or a cylinder pull instead. For Adams Rite MS1847 deadlock and deadlatch systems, ZenSupply carries the 4024 cylinder pull with trim plate mounting and the 4025 five pin cylinder pull with through-screws; on a wood door with the Adams Rite 5017 deadlock, the 4026 is the pull. If it is a straight mortise cylinder you need, the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder rated to a 1/2 inch minimum door thickness.

4) What is the difference between the Corbin Russwin 3070 LFIC rim housing and a Schlage full size interchangeable core rim cylinder?

Both are interchangeable core rim cylinders, but they are two different core formats and the cores are not shared between them. The Corbin Russwin 3070 is an LFIC rim housing for a Corbin Russwin large format core, supplied with rosette, compression spring, break-off screws and back plate. The Schlage Commercial 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam, and takes a Schlage full size core such as the 20-057-C in C keyway. Order the housing that matches the core format the facility already keys to.

5) What is the closest Schlage equivalent to the Corbin Russwin 3070 rim cylinder housing with a horizontal tailpiece?

The Schlage Commercial 20-022 is the nearest match in intent: it is a 6-pin rim cylinder with a horizontal tailpiece cam, the same tailpiece orientation the Corbin Russwin 3070 is supplied with at 1-7/8 inches. The difference is what you key. The 3070 is an LFIC rim housing sold less core, so the core is ordered separately and can be pulled and rekeyed with a control key. The 20-022 is a conventional rim cylinder shipped with 2 keys. Choose the 3070 when the building is on an interchangeable core program, the 20-022 when the opening is keyed conventionally.

6) The exit device needs a vertical tailpiece instead of a horizontal one. What should I order?

The Corbin Russwin 3070 is furnished with a 1-7/8 inch horizontal tailpiece, so it is the wrong orientation for a device that drives off a vertical tail. The Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and 2 keys. Confirm the orientation against the device manufacturer's cylinder chart before ordering, since rim devices from different makers take different cams on otherwise identical bodies.

7) Will a Medeco rim cylinder work in place of the Corbin Russwin 3070 on an exit device?

Look closely at what the Medeco rim cylinders in question are built for. 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. Those are deadbolt and handleset applications with lazy motion cams, not exit device drives. The Corbin Russwin 3070 is the exit device part, with a fixed 1-7/8 inch horizontal tailpiece and an LFIC core pocket.

8) The exit device trim takes a mortise cylinder, not a rim cylinder. What do I order instead of the 3070?

A rim housing will not thread into a mortise prep. The Corbin Russwin 3070 is a rim cylinder housing that mounts through the door with break-off screws and a back plate. For a mortise prep, the Detex MC65 is a 1-1/8 inch 6-pin commercial grade mortise cylinder in Schlage C keyway, and the Adams Rite 4036 is a five-pin Grade 1 mortise cylinder in the 4036 Series. Verify the cylinder length and cam required by the trim before ordering either.

9) What is the difference between an LFIC rim housing and a standard rim cylinder?

A standard rim cylinder is one piece: the plug, pins, and body are permanent, so rekeying means pulling the cylinder and repinning it. An LFIC housing like the Corbin Russwin 178 is a shell that accepts a removable large format interchangeable core. Pull the door key, insert the control key, and the core lifts straight out, so a locksmith or in-house maintenance tech can rekey an opening in seconds without removing the cylinder from the exit device. For a property with turnover, that is the reason to spec LFIC. For a single door that will never be rekeyed, a conventional rim cylinder is fewer parts and one less key system to administer.

10) Do I need to specify a hand for the Corbin Russwin 178 rim cylinder housing?

No handing to specify. The 178 is non-handed, so the same part goes on a left hand or right hand opening and you can stock one item for a whole building instead of splitting inventory by door swing.

11) What are the break-off screws on the Corbin Russwin 178 for, and can I still remove the cylinder later?

The break-off screws are a tamper feature. You tighten them until the heads shear away, which leaves nothing for a screwdriver or plier to grab on the outside of the door, so the housing cannot be twisted or backed off from the secure side. Because the housing takes an interchangeable core, that does not lock you out of servicing it: the core still comes out with the control key, so rekeying never requires touching those screws. Only a full housing replacement means drilling or extracting them.

12) Is the Corbin Russwin 178 a 6-pin or 7-pin housing, and does that matter for our masterkeying?

Six pins, on the Corbin Russwin 3000 Series keying system. That matters because the core you drop in has to be cut on the same system and pinned to the same chamber count as the rest of your building. If your key schedule was written around a 7-pin platform, this housing does not belong in it. A locksmith setting up a new master system for a site should settle the pin count and keyway before ordering housings, because the housing is the part you cannot change later without pulling it off the door.

13) The rim cylinder on our exit device is spinning in the door and the key will not turn it. Is this the replacement?

That is the classic failed rim cylinder mounting, and the 178 is sold as a replacement part for exit devices and exit device trim, so it is the right category of fix. Before ordering, confirm three things off the old part: that it is a Corbin Russwin large format interchangeable core opening, that the device takes a horizontal tailpiece (this one ships at 1-7/8 inches), and the finish code so the new rosette matches the rest of the trim. If the existing core is still good and correctly keyed, you can carry it over into the new housing.

14) Can a BEST interchangeable core be used in the Corbin Russwin 3070 rim housing?

Treat them as separate systems. The Corbin Russwin 3070 is an LFIC rim housing built for the Corbin Russwin 3000 Series keying program. BEST cores such as the 1C Series standard 5-pin core, the 1CB 150 Series core, or the 1CDF drill resistant patented 7-pin brass core are keyed and controlled on BEST's own system. If the property is standardized on BEST cores, specify a rim housing sold for that core format rather than fitting a core into a housing from another program.

15) We need a rim cylinder opening filled but no key function on that leaf. Is there a cheaper option than a full LFIC housing?

Yes. Where the hole has to be covered and dressed but the leaf is never keyed, the BEST 12E Series dummy rim cylinder at 1-5/32 inch diameter is a non-functioning rim cylinder made for that purpose. The Corbin Russwin 3070 is the choice when the opening actually operates: it is a working 6-pin LFIC rim housing for exit devices and exit device trim, supplied less core so the core can be swapped as the keying program changes.

16) Can a key-in-knob replacement cylinder be used where the Corbin Russwin 3070 is specified?

No, they serve different locks. The Kaba Ilco 1599 is a key-in-knob replacement cylinder, the 1539 is a key-in-knob and lever universal cylinder, the 1579 is a knob and lever cylinder for Sargent, and the Falcon A23161-05 G is a key in lever cylinder in RU/T Series 6-pin G keyway, keyed different with 2 cut keys. Those drop into knob and lever locksets. The Corbin Russwin 3070 is a rim housing for exit devices and exit device trim, non-handed, supplied less core with rosette, spring, break-off screws and back plate.

17) What finishes does the Corbin Russwin 178 rim cylinder housing come in?

Ten finishes, which is usually enough to match whatever is already on the exit device: 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 openings 626 and 630 are the two you will see most often, so if you are matching existing Corbin Russwin exit hardware and cannot read the finish code off the old part, those are the first two to compare against.

18) Is the Corbin Russwin 178 rim cylinder housing suitable for a residential door?

It is a commercial part and it only makes sense where there is commercial hardware to mount it on, specifically an exit device or exit device trim. Houses and most apartment unit doors have knobs, levers, and deadbolts instead, which take a key-in-knob or deadbolt cylinder, not a rim housing. For those, the Kaba Ilco 1539 key-in-knob and lever universal cylinder or the 1549 key-in-deadbolt cylinder are the relevant parts. Where the 178 does earn its place in multi-family is on the building's common exit doors.

19) Is the Corbin Russwin 3070 the right cylinder for a residential handleset or interconnected lock?

It is not the usual fit. The 3070 is a commercial LFIC rim housing for exit devices and exit device trim. Residential style handlesets and interconnected locks take purpose-built retrofit cylinders, such as the Medeco 1065140 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder, or the Emtek CY4 cylinder sold each. Match the cylinder to the lock body the door already carries.

20) Our facility standardizes on one finish across all doors. Does the Corbin Russwin 3070 cover the same finish range as the comparable rim cylinders?

The Corbin Russwin 3070 rim cylinder housing is offered in ten architectural 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. Among the comparable interchangeable core rim cylinders, the Schlage 20-057-C is called out in 643E aged bronze. If a facility is standardizing on 626 satin chrome or 630 satin stainless across a door schedule, the 3070 finish range covers those directly.
