April 28, 2015 – Kirk Key has developed what it calls “a reduced size mechanical bolt interlock for smaller stature breakers”.

Modeled on the Kirk Standard Duty series Type F, the smaller Type FF “ensures that workers follow a pre-determined 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 ½-in. stainless steel lock bolt to better fit in smaller cabinets. The proprietary 7-pin tumbler key design is “unique” to Kirk, said the company, and not available commercially, “minimizing the risk of circumventing safety sequences with duplicate keys”.

The Type FF footprint is 2 x 1¼-in. and is generally flat or face mounted with ¼-in. mounting bolts through the front of the housing. The reduced footprint of the Type FF is approximately 50% smaller and nearly 60% lighter, Kirk said, allowing for greater clearance around the breaker within the switchgear assembly.
