Schlage Commercial 20-200-CP Primus Classic Key-In-Lever Cylinder, 6 Pins, Sub-Assembled, Multiple Tailpiece

That is what the 20-200-CP is built for. It's a 6-pin Primus Classic cylinder sold as a replacement cylinder for Schlage commercial key-in-lever locks, driven by a tailpiece out the back rather than a threaded body and cam. Pull the existing cylinder and confirm you are looking at a key-in-lever cylinder and not a mortise or rim cylinder before you order, because those are different parts entirely.

No. The 20-200-CP is a Primus Classic 6-pin cylinder in the Schlage CP keyway, and a Primus key carries a side milling in addition to the top cuts. A conventional Schlage key without that side bitting will not turn it, even in a matching keyway. It works the other way around: a Primus key will operate conventional cylinders of the matching keyway, which is why Primus gets added to existing systems for the doors that need key control. Keys for it have to be cut on the CP Primus keyway.

It ships sub-assembled, so plan on your locksmith pinning it to your keying schedule. It is not a boxed keyed-different cylinder with cut keys in the package. If you want a key-in-lever cylinder that arrives already keyed with keys in hand, the Falcon A23161-05 G is listed as keyed different with 2 cut keys, though that one is a 6-pin G keyway and has nothing to do with a Primus system.

Cam type is Multiple Tailpiece, so more than one tailpiece comes with the cylinder and you fit the one that matches your lock chassis instead of sourcing a tailpiece separately. Take the old cylinder out first and match the tailpiece shape and length against what's supplied, since that is what decides whether the lever retracts the latch.

No hand to specify. The cylinder is non-handed, so the same part drops into a left-hand or a right-hand lever lock and the handing is settled by the lockset itself. Order it by keyway and finish instead, which for the 20-200-CP means the Schlage CP Primus keyway in 626 satin chrome.

No. The 20-200-CP is a key-in-lever cylinder that sits in the lever trim, not a threaded mortise cylinder. For mortise cases, the Corbin Russwin 1080 is a 1-1/2" 6-pin LFIC mortise cylinder built for Schlage L9000 mortise locks with an A01 Schlage L cam. The Corbin Russwin 1000 is a 1-1/2" Grade 1 mortise cylinder with an A02 straight cam, and the 1070 is a 1-1/4" 6-pin mortise housing with an A01 cloverleaf cam. The Detex MC65 is a 1-1/8" 6-pin commercial mortise cylinder in a Schlage C keyway. Which of those applies comes down to the cam the mortise case calls for and the cylinder length the door thickness allows.

It won't. Rim exit device trim takes a rim cylinder with a long flat tailpiece and a mounting plate behind it; the 20-200-CP is a key-in-lever cylinder. For an exit device, the Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece, which is the format that fits behind exit device trim.

Not directly. The 20-200-CP is a conventional 6-pin Primus Classic cylinder that gets pinned to your schedule and stays in the lock, so re-keying it means taking it apart rather than turning a control key and swapping a core. If the standard across the buildings is interchangeable core, BEST core products are the fit: the 1C Series is a standard 5-pin core, the 1CB is a 150 Series interchangeable core, and the 1CDF is a drill-resistant patented 7-pin brass core. Where the program is Primus key control on selected doors and cores everywhere else, the two can run side by side.

626 satin chrome is what the 20-200-CP comes in, and it's the standard finish on most commercial Schlage lever hardware, so it sits correctly alongside 626 levers, closers and exit devices. Only the cylinder face shows once it's installed, so the exposure is small either way. If the openings are 605 bright brass or 613 oil rubbed bronze, the chrome face will read differently against the rose.

The nearest peers by format are the Falcon A23161-05 G, a key-in-lever cylinder with a 6-pin G keyway supplied keyed different with two cut keys, and the Kaba Ilco 1539 universal key-in-knob/lever cylinder. All three sit in the outside trim of a keyed lever rather than in a mortise case or a rim device. Where they separate is the key system and the tailpiece: the 20-200-CP is a Primus Classic 6-pin cylinder in the Schlage CP keyway, shipped sub-assembled with a multiple tailpiece, while the Falcon runs the Falcon G keyway and the Ilco 1539 is a universal-style replacement. Those are three different key systems, so keys cut for a Primus CP system will not operate the Falcon or Ilco cylinders. The Schlage cylinder is non-handed, so it does not need to be specified left or right.

No. The Ilco 1549 is a key-in-deadbolt cylinder, built for the cylinder position in a deadbolt rather than in lever trim. The lever counterpart in that family is the Ilco 1539 key-in-knob/lever universal cylinder, and the Ilco 1599 is the key-in-knob replacement. The Schlage 20-200-CP is a key-in-lever cylinder, 6-pin Primus Classic, sub-assembled with a multiple tailpiece. If the opening is a keyed lever, the deadbolt cylinder is the wrong body for it no matter how the keying is set up.

The Kaba Ilco 1579 is a knob and lever cylinder made for Sargent locks, which is the right family when the chassis in the door is Sargent. The Schlage 20-200-CP is the Schlage-side answer to the same job: a 6-pin Primus Classic key-in-lever cylinder in the Schlage CP keyway, sub-assembled with a multiple tailpiece. A mixed building often ends up carrying both, since the cylinder has to match the lock chassis it is going into before keying is even discussed.

No, exit devices take a rim cylinder, which is a different body entirely. The Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8" tailpiece, which is the shape that fits behind a rim device. Watch the BEST 12E series here too: that one is a dummy rim cylinder at 1-5/32" diameter, so it fills the prep and matches the look without operating anything. The Schlage 20-200-CP is a key-in-lever cylinder with a multiple tailpiece and belongs in keyed lever trim.

That is the interchangeable core route rather than the key-in-lever route. The BEST 1CB is a Peaks 150 Series interchangeable core cylinder, the BEST 1C is a standard 5-pin cylinder core, and the BEST 1CDF is a drill resistant patented interchangeable core, 7-pin, brass, in the 150 Series. On the mortise side, the Corbin Russwin 1080 is a 1-1/2" 6-pin LFIC mortise cylinder for Schlage L9000 locks. The Schlage 20-200-CP is a sub-assembled 6-pin Primus Classic key-in-lever cylinder rather than a core-and-housing arrangement, so a facility standardizing on core swaps and one standardizing on Primus CP lever cylinders are making two different decisions about how the doors get serviced.

Narrow stile aluminum entrances take Adams Rite hardware, not key-in-lever cylinders. The Adams Rite 4036 is a Grade 1 five-pin mortise cylinder with a 1/2" minimum door thickness, which suits the thin stile of a glass front door. For the pull side, the 4024 is a cylinder pull with trim plate mounting and the 4025 is a five pin tumbler cylinder pull with through-screws, both designed for use with the Adams Rite MS1847 deadlock/deadlatch, while the 4026 is the five pin tumbler cylinder pull for wood door applications with the 5017 wood door deadlock/deadlatch. The Schlage 20-200-CP is a key-in-lever cylinder for commercial lever trim, so it is the interior and back-of-house answer rather than the storefront one.

Those are built for a different family of hardware. 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 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and the Emtek handleset and deadbolt outside cylinder, and the 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece. The Emtek CY4 is an Emtek cylinder sold each. All of those follow a handleset or deadbolt body. The 20-200-CP is a commercial key-in-lever cylinder, 6-pin Primus Classic with a multiple tailpiece, so it follows the lever chassis instead.

No, and the distinction is worth being precise about. The Detex MC65 is a 1-1/8" 6-pin commercial mortise cylinder cut in the Schlage C keyway, while the 20-200-CP is a Primus Classic 6-pin cylinder in the Schlage CP keyway. Those are two different keyway families, and the two cylinders are also two different bodies, one mortise and one key-in-lever. Separately, the Corbin Russwin 1080 is described as a fit for Schlage L9000 mortise locks with an A01 Schlage L cam, which is a match to the Schlage lock case rather than to a Schlage keyway. When a job is being kept on one key system, confirm the keyway on each cylinder rather than the brand name on the lock.
