Calibre Door Closers CL1000-KA2 Pair of Mortise Cylinders, 6-Pin Schlage C, Keyed Alike in Pairs

The CL1000-KA2 ships as a matched pair: one mortise key cylinder and one mortise thumbturn, both with an AR MS-type cam. Core faces, keys and the thumbturn are US 26D, and the cylinder faces (scalps) are anodized aluminum. A standard 3/16 inch cylinder trim ring is included with each.

They use an AR MS-type cam, which is the cam profile Adams Rite MS-series storefront deadlocks and deadlatches take. That is what makes this a storefront cylinder rather than a standard lockset cylinder, so if the door has a different cam requirement (Sargent, Yale, Schlage L-series style), this is not the right cam.

The key cylinder is cut for the 6-pin Schlage C keyway, so it accepts a Schlage C key blank and can be worked into an existing C-keyway system by your locksmith. As shipped it is keyed alike, not keyed to your system.

KA-2 means the two cylinders in a single pair operate on the same key. Plain KA extends that keying across a group, keyed alike in a maximum of 50 pairs each. If you are doing one storefront door, KA-2 is enough; if you want one key to open a row of entrances, specify KA.

Not as supplied. The Calibre CL1000-KA2 pair ships with an AR MS-type cam, which is the cam geometry used by MS-style storefront deadlocks, and it is furnished as a mortise key cylinder plus mortise thumbturn. A Sargent or Yale mortise lock body expects that manufacturer's own cam. For those bodies, the Schlage L583-197 is an L-Series mortise cylinder supplied with a Sargent/Yale cam for non-interchangeable-core cylinders. Match the cam to the lock body first, then confirm the keyway you want to key to.

They are both mortise cylinders, but they are built for different lock bodies and ordered differently. The Calibre CL1000-KA2 is sold as a keyed-alike pair with a 6-pin Schlage C keyway, an AR MS-type cam, a zinc die cast body with anodized aluminum scalp, and a 3/16 inch trim ring included, in Anodized Satin Aluminum, Anodized Black, or Anodized Storefront Bronze. The Schlage L583-197 is an L-Series mortise cylinder carrying a Sargent/Yale cam for non-IC cylinders. Choose by the cam the lock body requires, and by whether you need a matched keyed-alike pair or a single cylinder.

Two finishes are orderable: anodized satin aluminum (AL) and anodized storefront bronze (DU). The description also lists an anodized black (BK) option. Aluminum matches clear-anodized storefront framing and bronze matches dark bronze anodized framing, which is usually how the choice gets made on a glass front.

The Calibre CL1000 pair only comes with the AR MS-type cam, so it will not drive a Sargent or Yale mortise lock. For that cam profile, the Schlage Commercial L583-197 L-Series mortise cylinder with Sargent/Yale cam for non-IC cylinders is the part to look at.

A standard 3/16 inch cylinder trim ring is furnished with the cylinders. That covers the common storefront stile condition; if your door face requires more spacing than 3/16 inch to set the cylinder flush, you will need additional rings beyond what ships.

The Calibre CL1000-KA2 is supplied as a pair, a mortise key cylinder with a matching mortise thumbturn, keyed alike, and pairs can be specified KA-2 or KA for keying alike in groups of up to 50 pairs. If the opening needs a single cylinder rather than a key-and-thumbturn set, the Schlage L583-197 is an L-Series mortise cylinder ordered on its own, supplied with a Sargent/Yale cam for non-IC cylinders. Confirm the host lock body accepts that cam before ordering.

Not by itself, but the two are specified from different starting points. The Calibre CL1000-KA2 is built around a 6-pin Schlage C keyway and is furnished keyed alike in pairs, so it drops into a Schlage C masterkeyed property directly. The Schlage L583-197 is an L-Series mortise cylinder defined by its Sargent/Yale cam for non-IC cylinders, so it is selected to suit the lock body and the keyway is confirmed separately at order. For storefront MS-type deadlocks across a Schlage C property, the CL1000-KA2 pair is the direct fit.

Calibre lists the CL1000-KA2 as commercial. The body is zinc die cast with anodized aluminum scalps, and it is built around storefront entrance hardware rather than residential locksets.
