Schlage® full size conventional cylinders, including 7-pin SL cylinders, offer extreme versatility in a modular design. The cylinder is the foundation for any key-in-lever (KIL/KIK), rim or mortise application. Simply add the proper tailpiece to use in cylindrical locks, add front and rear housings with the right cam for mortise use or alternatively, housings plus cam and tailpiece for rim. With just a small inventory of parts facility managers and locksmiths can create cylinders to meet their immediate needs instead of ordering configured products allowing for on-the-job flexibility and reduced inventories. As a KIL solution, conventional cylinders are designed specifically to fit Schlage products, however, many variations are available to fit other manufacturers products.
