In this fourth and final installment, William M. Lynk, CML, CPS, ICML, CMIL, M.Ed., discusses popular systems designed for institutions. Schlage Everest 29 SL commonplace devices were reinvented to make our lives easier? Well, the future has arrived. Schlage has introduced a cylinder that allows existing Schlage E Everest SFIC systems to integrate into full-size cylinders, such as KIK, KIL, rim and mortise. Quite an advance. Where Did It Come From? How did the name “SL” come about? I assumed, at first it, was a melding of “SFIC” and Large KIL Shell,” but Monte Salway, CML, Schlage product manager for Commercial Key Systems, said it was actually named from the combination of Security and L-Pin. Whether SL means standard length, St. Lucia or Security and L-Pin, the concept is very cool. The Concept Schlage created the SL cylinder to allow the end users to in- tegrate their SFIC Everest 29 7-pin A2 system with a full-size cylinder format. It’s unique in that only a single pin is used in each chamber and will align with a sidebar when the correct key combination is used. These “L pins,” so called because of WWW.ALOA.ORG very once in a while, a new product or system comes along that provides us with exactly what we need: simplicity in a technically compli- cated world. Remember the wonder products of the 1950s where the futuristic designs of clumsy, their dimensional shape, can be used in non-master-keyed or master-keyed systems. Let’s take a look an exploded view of the SL cylinder in Fig- ure 65 to get a visual of how this cylinder is put together. You will quickly see that the SL is unlike a traditional SFIC in that it contains only one pin per chamber. Also, only two main components are in the plug in each chamber — the L-pin and the spring — aside from the sidebar, its springs and the plug cover. Anti-drill pins are strategically placed within the plug face, and the Everest check pin and spring are located near the keyway entrance. The body holds the SL in place, though the bible atop the cylinder has no real function other than to al- low for compatibility within the various full-sized housings. Compatibility, Integration and Application The SL cylinder will not only work with an existing Schlage Everest A2 small format system, but also with the Schlage KIL, KIK, mortise and rim modular cylinders, as well as other manufacturers’ brands of cylinders, such as Sargent, Corbin Russwin and Yale. SL is also compatible with new or existing Everest 29 or Primus XP cylinders that use Everest 29 R and Everest B keyways. Additionally, integrating SL cylinders into existing Schlage master-keyed systems will create no adverse affects on the systems’ expansion. One advantage of SL is that buildings on multiple key systems can now be brought into the same restricted key system at a much lower cost than replac- ing installed cylindrical lock hardware.
