KIRK^® is the industry leader and brand name associated with keyed safety interlock systems. Our wide range of mechanical and electro-mechanical interlocks can ensure that a predetermined sequence of operation is followed.

Interlocking is accepted by safety, insurance, and standards authorities throughout the world as the most reliable and cost effective way of guarding against operator error.

We manufacture three different styles of key interlocks - 1) our standard, brass, 7-pin tumbler interlocks, 2) the Hybrid Series for applications requiring a heavy duty key, and 3) the 316 Series stainless steel interlocks for high-corrosion, heavy duty applications. So regardless of the application, Kirk Key has the solution to your key interlocking requirements.
