Corbin Russwin 596K31 27B1 626 – Frequently Asked Questions

1) Will the Corbin Russwin 596K31 plug work in my CL3329 or CL3629 hotel lock?
Yes. The 596K31 is built specifically as a cylinder plug for Corbin Russwin CL3329 and CL3629 hotel mortise locks, so it drops into those cylinders without replacing the whole lock. It is not a general-purpose mortise cylinder for other lock series.
2) What do I have to specify when ordering a 596K31 X Class plug?
Three things: keyway, pin depth, and finish. Keyway is B1 or B2, pin depth is 27, 57, 67, or 77, and finish is either 606 satin brass or 626 satin chrome. All four pin depths are offered in both keyways and both finishes.
3) I'm keying to a B keyway master system already, is B1 or B2 the right plug for me?
Both are B family keyways, and they are not interchangeable with each other, so match the plug to whatever your existing system was set up under. Pull the keyway stamp off a key or an existing cylinder in the building and order B1 or B2 to match, then pick the pin depth (27, 57, 67 or 77) your keying schedule calls for.
4) We are replacing a whole mortise cylinder, not just the plug - what is a comparable complete cylinder?
If the cylinder shell itself is damaged rather than just the plug, a complete mortise cylinder is the right part. The Detex MC65 is a 1-1/8 inch 6-pin commercial mortise cylinder in the Schlage C keyway, and the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder rated for doors from 1/2 inch minimum thickness. Both put you on a different keyway than the Corbin Russwin B keyway that the 596K31 27B1 plug carries, so confirm how the opening is keyed into your master system first.
5) Can a Kaba Ilco universal cylinder be used instead of a Corbin Russwin 596K31 27B1 plug on a CL3329 hotel lock?
No. The 596K31 27B1 is a 5 and 6-pin individual X Class cylinder plug made specifically for Corbin Russwin CL3329 and CL3629 hotel mortise locks, so it drops into the existing Corbin Russwin cylinder shell. The Kaba Ilco 1539 is a key-in-knob and lever universal cylinder and the 1549 is a key-in-deadbolt cylinder - both are complete cylinders for knob, lever, and deadbolt bodies, not plugs for a mortise hotel lock cylinder. If you are rebuilding a CL3329 or CL3629 cylinder, stay with the Corbin Russwin plug.
6) I need an interchangeable core instead of a fixed plug - what should I look at?
The Corbin Russwin 596K31 27B1 is a conventional cylinder plug, meaning the cylinder must be disassembled to change keying. For a system where the core pulls with a control key instead, the BEST 1CB is a Peaks 150 Series interchangeable core cylinder and the BEST 1CDF is a drill-resistant patented 7-pin interchangeable core in the 150 Series. Schlage's 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam. Those are different keying platforms, so the change affects every opening on the system, not just the hotel locks.
7) Will the Corbin Russwin 596K31 plug work on an aluminum storefront deadlock?
No. It is a cylinder plug for Corbin Russwin CL3329 and CL3629 hotel mortise locks. For aluminum storefront work, the Adams Rite 4024 cylinder pull mounts with a trim plate and the 4025 five pin tumbler cylinder pull uses through-screws, both for MS1847 deadlock and deadlatch systems; the 4026 five pin tumbler cylinder pull is the wood door version for the Adams Rite 5017 deadlock and deadlatch. Glass front installers should be specifying from that Adams Rite group, not from a hotel mortise lock plug.
8) Is the 596K31 a 5-pin or 6-pin plug?
It covers both. The 596K31 X Class plug accommodates 5-pin and 6-pin cylinder arrangements, so one part number serves either chamber count on compatible Corbin Russwin locks.
9) What does X Class mean on a Corbin Russwin cylinder plug, and does it affect key duplication?
X Class is Corbin Russwin's individual key control designation. On the 596K31 it means duplication of keys for that plug is controlled rather than open, which is why it gets specified for hotel guestrooms and other buildings where a facility wants to keep the key system closed.
10) Can I use the 596K31 plug on a Schlage or BEST cylinder?
No. It is a Corbin Russwin plug with a Corbin Russwin B keyway and will not go into another manufacturer's cylinder. If you need a Schlage-keyway part instead, the Schlage Commercial 20-057-C is a full size interchangeable core in C keyway, and BEST interchangeable core work is served by cores like the BEST 1C Series 5-pin core. For a Schlage C keyway mortise cylinder, the Detex MC65 is a 6-pin 1-1/8 inch option.
11) I manage a hotel and want every guestroom cylinder the same, can I standardize on this part?
Yes, provided all your guestroom locks are CL3329 or CL3629. Order one keyway (B1 or B2), one pin depth, and one finish across the property and you have a single stocking part for cylinder rework, with X Class key control keeping duplication in your hands.
12) What is the difference between the Corbin Russwin 596K31 27B1 plug and a Schlage 20-021 rim cylinder?
They are not the same class of part. The 596K31 27B1 is a replacement cylinder plug carrying the B keyway and X Class key control, used to restore an existing Corbin Russwin CL3329 or CL3629 hotel lock cylinder. The Schlage 20-021 is a complete 6-pin rim cylinder with a vertical tailpiece cam supplied with two keys, and the 20-022 is the same rim cylinder with a horizontal tailpiece cam. Rim cylinders mount through the door to drive rim exit devices; they do not fit a mortise hotel lock cylinder body.
13) Is a Falcon A23161-05 G cylinder an alternative to the Corbin Russwin 596K31 plug?
Not for the same opening. The Falcon A23161-05 G is a key-in-lever cylinder for RU/T series locks, 6-pin, G keyway, supplied keyed different with two cut keys. The Corbin Russwin 596K31 27B1 is a 5 and 6-pin plug for CL3329 and CL3629 hotel mortise locks in the B keyway with X Class key control. Different lock platform and different keyway - use the Falcon only if you are servicing a Falcon key-in-lever, not a Corbin Russwin hotel mortise lock.
14) What do I order if the job is a Sargent lock rather than a Corbin Russwin hotel lock?
The 596K31 27B1 plug is built for Corbin Russwin CL3329 and CL3629 hotel mortise locks and will not serve a Sargent body. For Sargent knob and lever locks, the Kaba Ilco 1579 is the knob and lever cylinder made for Sargent. For a generic key-in-knob replacement the Kaba Ilco 1599 covers that application. Keep the Corbin Russwin plug for openings that already run the Corbin Russwin B keyway.
15) We need a high-security, patent-protected option instead of X Class key control - what are the choices?
X Class on the Corbin Russwin 596K31 27B1 gives individual key control at the plug level within the Corbin Russwin B keyway. If you want patent-protected or drill-resistant hardware instead, the BEST 1CDF is a drill resistant preferred patented interchangeable core, 7-pin, brass, 150 Series. Medeco cylinders such as the 1075127 5-pin rim type lazy motion single cylinder for handlesets and deadbolts are another route. Both move the opening off the Corbin Russwin keying system, so plan it as a system change rather than a single-part swap.
16) Is the BEST 1C5 core an equivalent to the Corbin Russwin 596K31 27B1?
They fill different roles. The BEST 1C5 is a standard 5-pin cylinder core from the Standard and Premium Cores line, designed to seat in BEST interchangeable core housings. The Corbin Russwin 596K31 27B1 is a plug that accommodates both 5-pin and 6-pin arrangements inside a Corbin Russwin CL3329 or CL3629 hotel lock cylinder and carries the B keyway with X Class key control. Choose the 1C5 only if the housings on your doors are BEST IC format.
17) Can I standardize a hotel property on one keyway using the 596K31 plug, or should I move to a different cylinder line?
The 596K31 27B1 keeps guestroom CL3329 and CL3629 locks on the Corbin Russwin B keyway, and it is stocked in B1 and B2 keyway variants across 606 satin brass and 626 satin chrome, with pin depths of 27, 57, 67 and 77. That lets you standardize within the Corbin Russwin system. Standardizing a mixed property on a single non-Corbin platform would instead mean a line like the BEST Peaks 1CB 150 Series interchangeable core or the Schlage 20-057-C full size interchangeable core in C keyway, 643E aged bronze - both of which require changing the cylinders in the doors, not just the plugs.
18) Do the 606 and 626 finishes on this plug need to match the lock trim?
Only the visible plug face shows, so most buyers match it to the cylinder face rather than the whole lockset. 606 satin brass suits brass and bronze openings, 626 satin chrome suits satin chrome and brushed nickel trim. Both finishes are available across every keyway and pin depth combination offered.
19) Is the 596K31 rated for hotel and institutional traffic, or is it light duty?
It is a commercial-duty part, not residential. Corbin Russwin builds the 596K31 for guestroom locks, offices, healthcare and institutional openings, schools, multi-tenant residential, and municipal buildings, which is the traffic level a hotel cylinder replacement program has to survive.
20) I need a non-keyed filler for an unused cylinder hole - is there a dummy option?
The Corbin Russwin 596K31 27B1 is a functioning keyed plug for CL3329 and CL3629 hotel locks, so it is not the part for a blank opening. The BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter is the piece that fills a rim cylinder hole without keyed function. Confirm the prep in the door matches a rim cylinder cutout before ordering it.
