Corbin Russwin 606K76 BR 626 – Frequently Asked Questions

1) Which mortise cylinder lengths does the 606K76 plug come in?
Four mortise lengths are offered: 2-1/4, 2-1/2, 2-3/4 and 3 inches. Match the length to the cylinder body already in the lock, since the plug length has to suit the housing depth and the door thickness that housing was sized for. Both finishes are available in all four lengths.
2) Will a BR keyway plug work in my existing Corbin Russwin master key system?
Only if that system runs the BR keyway. The plug is cut for the Corbin Russwin BR keyway, so key blades from another Corbin Russwin keyway won't enter it. It is an Individual X Class plug, which means it takes its place in a defined keying hierarchy and can be combinated into a master key system built on BR. Check the keyway stamp on the cylinders you are already maintaining before ordering.
3) Can I use this plug in a rim cylinder or a key-in-lever cylinder?
No. The 606K76 is built for mortise cylinder bodies only. For a rim application use a rim cylinder such as the Schlage 20-021 (vertical tailpiece cam) or 20-022 (horizontal cam). For key-in-knob or key-in-lever replacement, the Kaba Ilco 1599 key-in-knob cylinder or the Falcon A23161-05 G 6-pin key-in-lever cylinder cover that side.
4) Is the Corbin Russwin 606K76 a complete mortise cylinder or just the plug?
The 606K76 is a plug only - the 7-pin Individual X Class cylinder plug with the BR keyway, meant to go into a compatible Corbin Russwin mortise cylinder housing. If you need a complete, assembled mortise cylinder rather than a keying component, the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security, and the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder cut to the Schlage C keyway. Those two go in the lock as finished cylinders; the 606K76 is the keyed core component for an existing Corbin Russwin housing.
5) What should I use instead of the Corbin Russwin 606K76 if the door has a rim exit device rather than a mortise lock?
The 606K76 plug is built for mortise cylinder bodies, so it will not serve a rim device. For rim applications, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam supplied with two keys, and the Schlage 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam. Match the cam orientation to what your exit device calls for.
6) How does the 606K76 X Class plug differ from an interchangeable core like the BEST 1CDF?
Both are keying components rather than whole locks, but they are swapped differently. The Corbin Russwin 606K76 is a 7-pin Individual X Class plug with the BR keyway that is fitted into a compatible Corbin Russwin mortise cylinder housing. The BEST 1CDF is a 7-pin interchangeable core in the 1CDF drill-resistant patented 150 Series brass line, and the BEST 1CB is a 1CB Series Peaks 150 Series interchangeable core - cores of that style pull and drop in with a control key. The Schlage 20-057-C is a full size interchangeable core in the C keyway with a 643E Aged Bronze finish. If your facility is standardized on interchangeable cores, one of those is the direction; if the housings on the doors are Corbin Russwin mortise bodies keyed in BR, the 606K76 is the matching part.
7) Can I substitute a 5-pin cylinder for the Corbin Russwin 606K76 in a master keyed system?
Pin count has to match the system the key bitting was designed around. The 606K76 is a 7-pin plug, which is what supports the deeper keying hierarchy described for its X Class designation and master key use. The BEST 1C5 is a standard 5-pin cylinder core, the Adams Rite 4036 mortise cylinder is a five-pin design, and the Detex MC65 is 6-pin - none of those will accept a 7-pin BR bitting. Stay with the 7-pin plug if the existing keys are cut to a 7-pin Corbin Russwin system.
8) Will a Detex MC65 or Adams Rite 4036 key into my existing Corbin Russwin BR system?
No. The 606K76 plug is configured with the Corbin Russwin BR keyway so the key blade and system keying line up with existing BR installations. The Detex MC65 mortise cylinder is cut to the Schlage C keyway, and the Schlage 20-057-C full size interchangeable core is also a C keyway part. A different keyway means a different key blade, so those will not operate on BR keys. To keep one key across the building, stay in the BR keyway.
9) Is a 7-pin plug more secure than a standard 6-pin cylinder?
The 7-pin tumbler arrangement gives more key combinations and better pick resistance than a shorter pin stack, which is why it turns up on facilities running restricted key control. For comparison, the Detex MC65 mortise cylinder is a 6-pin and the Schlage 20-021 rim cylinder is 6-pin. Among 7-pin parts, the BEST 1CDF is a drill resistant 7-pin interchangeable core, though that is a core for a BEST housing, not a Corbin Russwin plug.
10) Is the 606K76 suitable for high traffic commercial doors like a school or hospital?
That is what it's for. The plug is classed commercial and is used in office buildings, schools, healthcare, government buildings, multi-tenant property and hospitality where mortise lock hardware is on restricted key control. Rekeying at the plug lets a facility keep the existing cylinder housings and lock bodies in the door.
11) Do I get keys with the 606K76 plug, or does it need to be keyed?
It's a plug supplied for keying into your system, not a packaged keyed-and-two-keys cylinder. Cutting and combinating to your BR system is a locksmith operation. If you want a cylinder that arrives keyed with cut keys, the Falcon A23161-05 G ships keyed different with 2 cut keys and the Schlage 20-021 rim cylinder comes with 2 keys.
12) What is the alternative to the 606K76 for a key-in-lever or key-in-knob lock instead of a mortise lock?
The 606K76 is a mortise-application plug and does not fit knob or lever cylinders. For key-in-knob and key-in-lever work, the Kaba Ilco 1539 Series is a universal key-in-knob / lever cylinder, the Kaba Ilco 1579 is a knob and lever cylinder for Sargent, the Kaba Ilco 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 two cut keys. For a key-in-deadbolt, the Kaba Ilco 1549 Series covers that function.
13) I need a keyed cylinder pull for an Adams Rite deadlock, not a mortise plug - what fits?
That is a different part family from the 606K76, which is a keying plug for Corbin Russwin mortise cylinder bodies. For Adams Rite deadlocks, the 4024 is a cylinder pull with trim plate mounting for MS1847 deadlock systems, the 4025 is a five pin tumbler cylinder pull with through-screws for the MS1847, and the 4026 is a five pin tumbler cylinder pull for wood door applications with the 5017 wood door deadlock or deadlatch.
14) Is there a non-keyed option if the opening only needs a filler and not a working cylinder?
The 606K76 is a functioning keyed plug in the BR keyway for X Class systems, so it is more part than a blank opening needs. Where a cylinder position has to be filled without keying it, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter serves that role on rim prep. Note it is a rim-pattern part, not a mortise plug.
15) What replaces the 606K76 for residential handleset and deadbolt retrofits?
The 606K76 is specified for commercial use with Corbin Russwin mortise hardware. On residential-style handlesets and deadbolts, the retrofit cylinders are different: the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the Medeco 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece, and the Medeco 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder. The Emtek CY4 is also offered as a single cylinder.
16) Does the mortise length matter when comparing the 606K76 to other mortise cylinders?
Yes - the 606K76 is offered in 2-1/4 inch, 2-1/2 inch, 2-3/4 inch and 3 inch mortise lengths, in 606 Satin Brass and 626 Satin Chrome, so the length has to match the lock body and door thickness you are working with. Among complete mortise cylinders, the Detex MC65 is specified at 1-1/8 inch diameter with the Schlage C keyway, and the Adams Rite 4036 is a Grade 1 mortise cylinder listed down to a 1/2 inch minimum door thickness. Confirm the dimension your lock case was prepped for before ordering across brands.
17) Is this a genuine Corbin Russwin part or an aftermarket copy?
Genuine Corbin Russwin. The 606K76 BR is an authentic Corbin Russwin cylinder part, which is what keeps the fit and finish consistent with the mortise cylinder housings already installed. Aftermarket universal cylinders like the Kaba Ilco 1539 or 1579 exist for other brands' locks, but they are not Corbin Russwin plugs and won't serve a BR X Class system.
