Corbin Russwin 135F19-2 – Frequently Asked Questions

1) What exactly is the Corbin Russwin 135F19-2 part?
It is the Master Ring A64 component for Corbin Russwin cylinders, a small internal ring that goes inside the cylinder rather than a complete cylinder assembly. Corbin Russwin part model 135F19-2. If you need a whole keyed cylinder for a lockset, this is not it.
2) Is the 135F19-2 the same thing as a Corbin Russwin 2MR?
Same part. 2MR is the legacy designation for the Master Ring A64, now catalogued by Corbin Russwin as 135F19-2, so older drawings and service sheets calling out 2MR are pointing at this component.
3) Which cylinders does the Corbin Russwin Master Ring A64 fit?
It is made for compatible Corbin Russwin cylinder assemblies as a direct replacement ring, and it is an OEM Corbin Russwin part. It is brand-specific, so it will not serve as a master ring in a BEST, Schlage, or Kaba Ilco cylinder.
4) Is the Corbin Russwin 135F19-2 Master Ring A64 a complete cylinder, or do I need a full cylinder instead?
The 135F19-2 is a Master Ring A64 (formerly 2MR) replacement component for compatible Corbin Russwin cylinder assemblies, not a complete cylinder. If the job calls for a whole cylinder rather than a ring, options include the Adams Rite 4036 mortise cylinder with five-pin security, the Detex MC65 mortise cylinder with Schlage C keyway in 1-1/8 inch 6-pin, or the Schlage Commercial 20-021 rim cylinder with vertical tailpiece cam supplied with 2 keys.
5) We want to stop replacing rings and move to a keying system where the core pulls out. What should we look at?
The Corbin Russwin 135F19-2 is a Master Ring A64 part that lets you service an existing cylinder assembly component by component instead of swapping the whole cylinder. If you would rather rekey by pulling a core, interchangeable-core products serve that approach: the BEST Peaks 1CB 150 Series interchangeable core cylinder, the BEST 1CDF drill resistant patented interchangeable core in 7-pin brass 150 Series, or the Schlage Commercial 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam.
6) Which cylinder options carry a stated grade or keyway if my spec sheet calls one out, since the 135F19-2 is a component part?
The 135F19-2 is the Corbin Russwin Master Ring A64 service component, so specify at the cylinder level. The Adams Rite 4036 mortise cylinder is listed as Grade 1 in the 4036 Series with a 1/2 inch minimum door thickness. For keyway callouts, the Detex MC65 is a 6-pin mortise cylinder in Schlage C keyway at 1-1/8 inch, the Schlage 20-057-C is a full size interchangeable core in C keyway with a 643E aged bronze finish, and the Falcon A23161-05 G uses a 6-pin G keyway.
7) Can I replace just the master ring instead of the whole cylinder?
That is the point of stocking the 135F19-2. It lets a locksmith or maintenance tech swap the ring component during service rather than pulling and rekeying an entire cylinder assembly, which keeps the existing keying and the rest of the cylinder in place.
8) I need a full replacement cylinder, not a ring. What should I look at instead?
Look at complete cylinders rather than this ring component. For rim applications, Schlage's 20-021 (6-pin, vertical tailpiece cam) and 20-022 (6-pin, horizontal tailpiece cam) are complete rim cylinders. For interchangeable core work, the BEST 1C Series standard 5-pin core or the Schlage 20-057 6-pin FSIC rim cylinder cover that. For key-in-knob or lever replacement, the Kaba Ilco 1599 is a key-in-knob replacement cylinder.
9) Is the 135F19-2 a keyed part, and does it come with keys?
No keys. The Master Ring A64 is an unkeyed internal cylinder component, not a pinned cylinder. If you want a cylinder supplied with cut keys, products like the Schlage 20-021 rim cylinder ship with 2 keys and the Falcon A23161-05 G key-in-lever cylinder comes keyed different with 2 cut keys.
10) Will a master ring part like this work in a Corbin Russwin interchangeable core system?
The Master Ring A64 is a conventional cylinder component for Corbin Russwin cylinder assemblies. Interchangeable core systems are a different construction and are serviced by swapping the core itself, such as a BEST 1CB 150 Series interchangeable core or a Schlage 20-057-C full size interchangeable core. Confirm the cylinder you are servicing is a conventional master ring cylinder before ordering.
11) I need a cylinder for a key-in-knob or key-in-lever lock, not a ring part like the 135F19-2. What are the choices?
The 135F19-2 is a Master Ring A64 cylinder component, so it will not serve as a knob or lever cylinder. For that, the Kaba Ilco 1539 Series is a key-in-knob/lever universal cylinder, the 1579 Series is a knob and lever cylinder for Sargent, the 1599 is a key-in-knob replacement cylinder, and the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T Series 6-pin G keyway, keyed different with 2 cut keys.
12) Is the Corbin Russwin 135F19-2 an appropriate part for an aluminum storefront deadlock?
The 135F19-2 is a Corbin Russwin Master Ring A64 cylinder component for compatible Corbin Russwin cylinder assemblies, so it is not matched to a storefront deadlock by itself. For Adams Rite MS1847 deadlock/deadlatch openings, the Adams Rite 4024 cylinder pull mounts with a trim plate and the 4025 is a five pin tumbler cylinder pull with through-screws; for wood doors, the 4026 five pin tumbler cylinder pull is designed for the Adams Rite 5017 wood door deadlock/deadlatch.
13) For residential handleset and deadbolt retrofits, is the Corbin Russwin 135F19-2 the right part?
No. The 135F19-2 is specified for commercial door hardware as a Corbin Russwin cylinder service component. For handleset and deadbolt retrofits, the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065244 is a 5-pin rim lazy motion cylinder with Emtek tailpiece, and the 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders.
14) Does the tailpiece cam orientation matter when I am choosing between rim cylinders rather than a ring part like the 135F19-2?
Yes, and the 135F19-2 does not address it since it is a Master Ring A64 component rather than a cylinder. Among rim cylinders, the Schlage Commercial 20-021 is a 6-pin with a vertical tailpiece cam and the 20-022 is a 6-pin with a horizontal tailpiece cam, both supplied with 2 keys, while the 20-057 uses a convertible tailpiece cam on a 6-pin FSIC rim cylinder. Match the cam to the exit device or lock body you are feeding.
15) Is this a residential or commercial door hardware part?
Commercial. The Master Ring A64 is built to Corbin Russwin's commercial hardware standards and turns up in office buildings, schools, hospitals, municipal buildings, hotels, warehouses, and multi-tenant residential maintenance work.
16) Is the Emtek CY4 cylinder a substitute for the Corbin Russwin 135F19-2?
No. The Emtek CY4 is a cylinder sold each as an Emtek part, while the 135F19-2 is the Corbin Russwin Master Ring A64 (formerly 2MR) engineered for compatible Corbin Russwin cylinder assemblies. A ring component and a cylinder are not cross-usable, and the 135F19-2 is the OEM Corbin Russwin part for Corbin Russwin service work.
