Schlage Commercial L583-197 L-Series Mortise Cylinder Sargent/Yale Cam for Non-IC Cylinders

It is a replacement cam for a Schlage L-Series mortise cylinder, cut to the Sargent/Yale cam pattern rather than the standard Schlage pattern. You use it when the mortise cylinder has to drive a Sargent or Yale style mortise lock body. It is a commercial part and it works with conventional (non-interchangeable core) cylinders only.

No. The L583-197 is specified for non-IC cylinders, meaning conventional mortise cylinders with a threaded shell and a tailpiece screw. An interchangeable core housing uses its own drive lug arrangement and this cam will not fit it. If the opening runs IC cores, you need the IC housing and the matching cam for that system instead.

Yes, with the right cam. Mortise cylinders share a common 1-5/32 inch, 32 thread-per-inch shell across the major brands, so the body threads into a Sargent or Yale case fine. What differs is the cam that turns the lock hub. Fitting the L583-197 Sargent/Yale cam to the Schlage L-Series cylinder lets it drive that lock body, which is how you keep an existing keyway across mixed lock brands in one building.

The Schlage L583-197 is a Sargent/Yale-style cam for non-interchangeable-core mortise cylinders in the L-Series line, so it is a cam component rather than a keyed cylinder you can drop into a mortise lock. If the opening needs actual cylinders, the Calibre Door Closers CL1000-KA2 is supplied as a pair of mortise cylinders, 6-pin Schlage C keyway, keyed alike in pairs. Order the CL1000-KA2 when you need working cylinders and a key, and order the L583-197 when you already have a non-IC mortise cylinder that needs the Sargent/Yale cam to drive the lock it is going into.

That is the exact job it does. Instead of maintaining two keyways because some doors carry Sargent or Yale mortise locks, you fit Schlage L-Series mortise cylinders throughout and swap in the L583-197 cam on the ones going into the Sargent or Yale cases. One keyway, one master system, one set of keys for the maintenance staff.

It is the cam only. You supply the conventional Schlage mortise cylinder, remove the factory cam and its retaining screw, and fit this one. If you need a complete keyed mortise cylinder instead, the Calibre CL1000-KA2 is sold as a pair of 6-pin Schlage C mortise cylinders keyed alike.

No. Handing on a mortise lock is set in the lock case by reversing the latchbolt and the hub, not by the cylinder. The L583-197 only changes what the cylinder plug drives, so the same cam serves left and right hand openings.
