Corbin Russwin CR1000-134-A01-6-L4 626 – Frequently Asked Questions

1) Will the Corbin Russwin 134-A01 mortise cylinder work in my mortise lock, or do I need a specific model?

The 1000 Series conventional mortise cylinder in the 1-3/4 inch length works with all mortise locks and with DL3000 deadlocks. The part that actually decides the fit is the cam: this one carries the A01 Cloverleaf cam, so the lock you are putting it into has to be an A01 Cloverleaf application. The 1000 Series platform also offers A02 Straight, A03 Adams Rite MS, A04 DL4000, A05 Adams Rite 4070, A06 Schlage Cloverleaf, A07 DL4100, and A62 900 KRM Straight cams, so pull the old cylinder and match the cam before you order.

2) What cylinder length do I need for a 1-3/4 inch commercial door, and is the Corbin Russwin 1000 Series 1-3/4 inch cylinder the right one?

Careful here, because the two numbers get confused constantly. The 1-3/4 inch (44mm) figure on this cylinder is the cylinder length, not the door thickness. Cylinder length is set by how deep the lock body sits and how much face trim or armor plate stands off the door, so measure the old cylinder from the shoulder to the back rather than assuming it matches the door. Corbin Russwin builds the 1000 Series from 1-1/4 inch (32mm) up to 2-1/2 inch (64mm), with 1-3/8 inch (35mm), 1-3/4 inch (44mm), 2 inch (51mm), 2-1/4 inch (57mm), and 2-1/2 inch (64mm) steps in between.

3) Which keyway do I order so the new Corbin Russwin cylinder works on my existing master key system?

Order the keyway your system is already built on, and nothing else will key to it. The 1000 Series 1-3/4 inch cylinder is offered in 84 keyways, covering the 27, 57, 59, 67, 77, and 97 through 99 families, the 981/982/983 and 252, 60, and 70 keyways, the AR, BL, BR, G, D1/D2, H1 through H8, and L1 through L4 sections, and N1 through N28. Your keying schedule or the bitting on the existing key names the section. If you are starting fresh, pick one section and stay on it across the building so the master system can expand later.

4) I have an Adams Rite storefront deadlock. Will the Corbin Russwin 134-A01 cylinder fit it?

Not as configured. The A01 Cloverleaf cam on this one is for mortise locks and DL3000 deadlocks. Adams Rite MS hardware takes the A03 cam and the 4070 takes A05, both of which the 1000 Series offers, so specify that cam instead of A01. For an aluminum storefront where you want the cylinder from the same brand as the lock, the Adams Rite 4036 mortise cylinder is a Grade 1 option that goes down to a 1/2 inch minimum door thickness.

5) What is the difference between the Corbin Russwin 134-A01 mortise cylinder and a rim cylinder like the Schlage 20-021?

They mount in different lock bodies and are not interchangeable. The Corbin Russwin 134-A01 is a conventional mortise cylinder, 1-3/4 inch length, that threads into the cylinder hole of a mortise lock case and drives the lock through an A01 Cloverleaf cam. The Schlage Commercial 20-021 is a rim cylinder with a 6-pin plug and a vertical tailpiece cam, which mounts through the door from the inside and drives rim-mounted hardware with a tailpiece rather than a cam. If the lock in the door is a mortise case or a DL3000 deadlock, the threaded mortise cylinder is the correct format; if it is a rim exit device, the rim cylinder is. Schlage also lists the 20-022 with a horizontal tailpiece cam for rim hardware that needs the tailpiece oriented the other way.

6) I need a mortise cylinder for an Adams Rite MS deadlock instead of a standard mortise lock case. What should I order?

Adams Rite narrow stile deadlocks take a cylinder configured for their cam. The Adams Rite 4036 is a mortise cylinder with five-pin security, Grade 1, in the 4036 Series, and it fits doors from 1/2 inch thickness minimum, which is what makes it suited to aluminum narrow stile. The Corbin Russwin 1000 Series conventional mortise cylinder addresses the same application through cam selection rather than a separate part: the 1000 Series platform supports the A03 Adams Rite MS cam and the A05 Adams Rite 4070 cam alongside the A01 Cloverleaf. So the choice is between an Adams Rite cylinder built for that lock family and a Corbin Russwin 1000 Series cylinder ordered with the matching Adams Rite cam, which is the route to take when the opening has to stay on an existing Corbin Russwin keyway.

7) The lock on the door is a key-in-lever, not a mortise lock. Does the Corbin Russwin 134-A01 fit it?

No. The Corbin Russwin 134-A01 is a conventional mortise cylinder for all mortise locks and DL3000 deadlocks, and it drives the lock with a cloverleaf cam. A key-in-lever or key-in-knob lock takes a cylinder built to that lock's format instead. Kaba Ilco covers those with the 1539 Series key-in-knob and lever universal cylinder, the 1579 for Sargent knob and lever locks, and the 1599 key-in-knob replacement cylinder. Falcon lists the A23161-05 G key-in-lever cylinder for the RU/T Series, 6-pin G keyway, keyed different with 2 cut keys. Confirm the lock body format before ordering, because a mortise cylinder and a key-in-lever cylinder are not the same part in a different finish.

8) What finishes does the Corbin Russwin 1000 Series mortise cylinder come in, and which one matches my existing lever 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 the trim already in the door rather than the description of the color, since 626 satin chrome and 619 satin nickel read very similar at a glance but do not match side by side. 626 is the usual commercial default.

9) What do I need to specify when ordering a Corbin Russwin 1000 Series mortise cylinder?

Four things, and getting any of them wrong means the part will not work. Cam, which is A01 Cloverleaf on the 134-A01. Length, 1-3/4 inch (44mm) here, out of a range that runs 1-1/4 inch to 2-1/2 inch. Keyway, one of 84 sections, matched to your existing system. Finish, one of seven from 605 bright brass to 626 satin chrome. Hand is not on the list, since the cylinder is non-handed.

10) Can I standardize a whole building on one mortise cylinder and still have separate keys per tenant?

Yes, and that is the normal way this gets specified. The 1000 Series is built to sit inside a master key system, so every door can take the same 1-3/4 inch A01 cylinder while the keying schedule sets who opens what: individual change keys per unit, a master for the floor, a grand master for the building. Keep every cylinder on the same keyway section and the system stays expandable when you add doors later. Corbin Russwin publishes the full key system detail in its Key Systems Catalog.

11) Does the Corbin Russwin 134-A01 mortise cylinder come with keys?

Two keys ship with each cylinder. If it is going onto a keyed-alike or master keyed system, the keys need to be cut to your existing bitting, which is a keying decision made at order time rather than something you fix in the field.

12) Is the Corbin Russwin 1000 Series mortise cylinder rated for commercial traffic, or is it a residential part?

Commercial. The 1000 Series mortise cylinder is a commercial keying component, used in offices, schools, healthcare, retail, government buildings, industrial facilities, and multi-tenant residential. If you are looking at a residential deadbolt or handleset instead, that is a different cylinder type entirely, closer to something like the Kaba Ilco 1549 key-in-deadbolt cylinder.

13) Do I need to worry about handing when choosing between the Corbin Russwin 134-A01 and other mortise cylinders?

The Corbin Russwin 134-A01 is non-handed, so the same cylinder serves left-hand and right-hand openings and the order comes down to length, cam and keyway rather than door swing. What does vary by peer is the drive format and how it is oriented. Schlage's rim cylinders split on that point, the 20-021 with a vertical tailpiece cam and the 20-022 with a horizontal tailpiece cam, so those have to be picked to match the hardware behind the door. With a mortise cylinder the cam does that job instead, and the 1000 Series carries cam options including A01 Cloverleaf, A02 Straight, A06 Schlage Cloverleaf and A62 900 KRM Straight.
