Corbin Russwin CR1000-118-A01-6-L4 626 – Frequently Asked Questions

1) Does the Corbin Russwin 118-A01 mortise cylinder come keyed, or do I have to have it cut?

It ships 0-bitted. There are no cuts in the plug, so a locksmith has to pin and cut it to your system before it will operate anything. Two key blanks come with it. That is the point of ordering it this way: you pick the keyway up front and the cylinder gets keyed into your existing master key system rather than arriving on a random keyed-different bitting you would have to throw away.

2) Can I use a Corbin Russwin 1000 mortise cylinder in an Adams Rite deadlock on a glass storefront door?

Not with the A01 Cloverleaf cam. Adams Rite hardware needs its own cam profile, and the 1000 Series covers that with the A03 Adams Rite MS cam and the A05 Adams Rite 4070 cam rather than A01. If you would rather buy the cylinder from the same maker as the lock, the Adams Rite 4036 mortise cylinder is a five-pin Grade 1 unit that fits from 1/2 inch minimum thickness, which suits narrow stile aluminum.

3) I'm replacing a failed cylinder on one door. What do I have to specify to get an exact match?

Four things decide it. Length, here 1-1/8 inch. Cam, here A01 Cloverleaf. Keyway, so the existing building keys work, chosen from the 84 the 1000 Series offers. Finish, matched to the BHMA number on the surrounding trim. Pull the old cylinder before you order and read the plug face for the keyway stamp. The replacement comes 0-bitted, so budget for a locksmith visit to key it to the system, and note the two blanks it includes are uncut.

4) What is the closest equivalent to a Corbin Russwin 1000 Series 1-1/8 inch mortise cylinder from another manufacturer?

The Detex MC65 is the nearest match in the conventional mortise family: it is a 1-1/8 inch, 6-pin commercial mortise cylinder, the same length and pin count as the Corbin Russwin 1000 Series conventional mortise cylinder specified at 1-1/8 inch with a 6-pin body. The difference that decides the order is the key system. The MC65 is supplied in the Schlage C keyway, so it keys into a Schlage C system. The Corbin Russwin 1000 Series is offered across the Corbin Russwin keyway range including 27, 57, 59, 67, 77, D1, L4 and the N-series keyways, and comes 0-bitted for a locksmith to key into an existing Corbin Russwin master key system. If the building is keyed Corbin Russwin, the 1000 Series stays in system; if the building is keyed Schlage C, the MC65 does.

5) Can a Schlage 20-021 rim cylinder be used in place of a Corbin Russwin 118-A01 mortise cylinder?

No. The Schlage 20-021 is a rim cylinder, driven by a vertical tailpiece cam, and it mounts through the door face behind a rim exit device. The Corbin Russwin 1000 Series 118-A01 is a conventional mortise cylinder that threads into the cylinder hole of a mortise lock case and turns the lock through an A01 cloverleaf cam. The two are not interchangeable in either direction: a rim cylinder has no threaded body to screw into a mortise case, and a mortise cylinder has no tailpiece to reach a rim device. Confirm whether the lock on the door is a mortise case or a rim exit device before ordering. Schlage also lists the 20-022 rim cylinder with a horizontal tailpiece cam, which is the same rim family and equally not a mortise substitute.

6) What mortise cylinder should be used on an Adams Rite narrow stile aluminum door instead of a Corbin Russwin 1000 Series?

The Adams Rite 4036 mortise cylinder is the one built for that opening. It is a Grade 1 five-pin mortise cylinder from the 4036 series with a door thickness range starting at a 1/2 inch minimum, which is what a narrow stile aluminum door needs. The Corbin Russwin 1000 Series conventional mortise cylinder is a 6-pin cylinder intended for all mortise locks and DL3000 deadlocks. Note that the 1000 Series platform does support cam options for Adams Rite work, including the A03 Adams Rite MS cam and the A05 Adams Rite 4070 cam, so a Corbin Russwin cylinder can serve an Adams Rite deadlock when the building is keyed Corbin Russwin and the stile accepts it. The A01 cloverleaf cam is not one of those; specify the cam by the lock it drives.

7) Is a 6-pin mortise cylinder enough for a commercial master key system?

Six pins is what the 1000 Series ships as standard, and it is the normal chamber count for a commercial Corbin Russwin master key system. The extra chamber over a 5-pin gives your locksmith more room for master and grand master cuts before the system runs out of usable combinations, which matters if you are keying a whole facility rather than a couple of doors. It is rated commercial, not residential.

8) Does a mortise cylinder come with the trim ring or collar I need to install it?

What you get is the cylinder itself plus two uncut key blanks. Mortise cylinders thread into the lock case and are held by a set screw already in the lock, so on a straight replacement you normally reuse the existing collar or ring. If the old cylinder sat behind a spacer collar to make up trim thickness, keep it, because the 1-1/8 inch length assumes that same stack. A cylinder that sits low in the trim usually means a collar went missing, not that the length is wrong.

9) What is the difference between a Corbin Russwin 1000 Series conventional mortise cylinder and a BEST interchangeable core cylinder?

They are two different key system architectures. The Corbin Russwin 1000 Series is a conventional mortise cylinder: the pinning lives in the cylinder body, it arrives 0-bitted for a locksmith to key, and rekeying means pulling the cylinder out of the mortise case and taking it apart. BEST offers interchangeable core cylinders instead, including the 1CB Peaks 150 Series interchangeable core and the 1CDF drill resistant patented 7-pin brass 150 Series core, where a control key pulls the core out and a new core drops in without disassembling anything. Facilities that expect frequent tenant turnover and want in-house rekeying tend toward interchangeable core; facilities standardized on a Corbin Russwin master key system stay with the 1000 Series conventional cylinder, which is offered across the Corbin Russwin keyway range.

10) What finishes does the Corbin Russwin 1000 mortise cylinder come in, and which one matches my existing lock 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 BHMA number on your existing trim, not the description, since satin chrome 626 and satin nickel 619 look close at a glance but do not match side by side. 626 is the usual commercial standard for a building already running Corbin Russwin trim.

11) Is the Corbin Russwin 1000 mortise cylinder brass, and will it hold up outside or in a coastal building?

The body is solid brass at 1-5/32 inch diameter. Brass does not rust, which is why it is the standard material for exterior commercial cylinders, and the plated finish is what wears first rather than the body. For an exposed door on the weather side, the darker finishes such as 613 satin bronze oil-rubbed and 612 satin bronze hide wear better than a bright plate like 605 bright brass or 625 bright chrome.

12) Is a BEST 12E dummy rim cylinder an alternative to a Corbin Russwin 1000 Series mortise cylinder on an unkeyed opening?

No, and the shared dimension is what makes it worth checking. The BEST 12E Series dummy rim cylinder has a 1-5/32 inch diameter, the same body diameter as the Corbin Russwin 1000 Series solid brass cylinder, but it is a dummy rim cylinder: it fills the hole and matches the finish without operating anything, and it mounts as a rim cylinder rather than threading into a mortise case. The Corbin Russwin 1000 Series is a functional conventional mortise cylinder supplied 0-bitted with 2 keys for a locksmith to key into a master key system. Use a dummy only where the opening carries no lock function.

13) What cylinder handles a high security or drill resistant requirement that a Corbin Russwin 1000 Series does not?

For a patented, drill resistant specification the BEST 1CDF is the part to look at: it is a drill resistant preferred patented interchangeable core cylinder, 7-pin, brass, in the 150 Series. Medeco cylinders in the comparable range are retrofit formats rather than mortise, such as the 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts and the 1065140 5-pin retrofit cylinder for the Arrow JL interconnected lock. The Corbin Russwin 1000 Series is a conventional 6-pin mortise cylinder in solid brass, supplied 0-bitted for master keying, and it is the format that threads into a mortise lock case. Match the security level to the door only after confirming the lock case accepts a mortise cylinder.

14) Is a Falcon A23161-05 G key in lever cylinder a substitute for a Corbin Russwin mortise cylinder?

No. The Falcon A23161-05 G is a key in lever cylinder in the RU/T Series with a 6-pin G keyway, supplied keyed different with 2 cut keys, and it fits the cylinder pocket of a lever lock. A key in lever cylinder cannot thread into a mortise lock case. The Corbin Russwin 1000 Series is a conventional mortise cylinder for all mortise locks and DL3000 deadlocks, supplied 0-bitted with 2 key blanks so a locksmith can key it into the existing system rather than delivering it keyed different. Match the cylinder format to the lock case first, then the keyway to the building.

15) What is a simpler cylinder option than a 6-pin Corbin Russwin 1000 Series for a lower security interior opening?

The BEST 1C Series standard 5-pin cylinder core is the reduced pin count option in the comparable range, part of the standard and premium cores family, and it works within a BEST interchangeable core system. Adams Rite also builds five-pin cylinders, including the 4036 Grade 1 mortise cylinder with five-pin security. The Corbin Russwin 1000 Series carries a 6-pin configuration as standard, which is the pin count a commercial master key system generally expects when the interior doors have to sit under the same top master key as the perimeter. If the interior opening is on the building master key system, the pin count has to match the system, not the door.
