The Type FF interlock, which has a reduced sized bolt for smaller stature breakers, ensures that workers follow a predetermined sequence of operation to safely access electrical switchgear.
Manufactured with a brass lock housing and cylinder, the Type FF has a ¾ in. travel, with a smaller diameter ½ in. stainless steel lock bolt to better fit in smaller cabinets. The proprietary 7-pin tumbler key design is unique to Kirk and not available commercially, minimizing the risk of circumventing safety sequences with duplicate keys.
