Overview

Schlage Full Size Interchangeable Core (FSIC) cylinders are offered in 6-pin length and a 7-pin length as an SL cylinder. They  are available in a variety of different keyway families – open and restricted. Sometimes referred to as LFIC, these interchangeable types of cores are a convenient solution in large buildings or campuses where frequent rekeying occurs, often due to tenant changeover. Schlage FSIC formatted cylinders are upgradeable to Primus levels of security and share keyways with Schlage conventional cylinders.
