Smaller footprint bolt lock offers greater product options for switchgear applications
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.
Kirk Key has developed a reduced size mechanical bolt interlock for smaller stature breakers. Modelled 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 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.
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, allowing for greater clearance around the breaker within the switchgear assembly.
The Type FF, in conjunction with Kirk’s current comprehensive line of Standard Duty bolt, electro-mechanical, access, transfer, and cylinder interlocks, creates a complete trapped key interlock system for switchgear and other process safety applications.
