Simplify keying and rekeying around your facility with locks that let you slot in your own cylinder. These locks make expanding your facility or adding more padlocks easy—just match the cylinders to your existing keying system, even if your key number isn’t common. If you need to rekey your locks, just swap out the cylinders instead of replacing the entire padlock. They accept easy-change lock cylinders, which are also called small format interchangeable core (SFIC) cylinders. To install and remove a cylinder, you'll need a control key that matches the cylinder (not included).
