The Kirk Key brand is so well-known in the North American industrial community that “Kirk Key” is often used to mean any kind of trapped key interlock, regardless of manufacturer. Its interlock systems are custom-configured to meet each user’s requirements and revolve around a key or keys that an operator must use at each step in the pre-determined sequence.
Kirk maintains end user records dating back to the 1940s, aiding companies that need to add to or repair their older interlock scheme.
The headquarters is in North Canton, Ohio, USA, with a network of sales agents around the world.
Kirk operates within the Halma Process Safety Sector.
