Our products

Our interlock products are customized
to your unique safety needs


The keying of KIRK® safety interlock systems is the critical piece in sequencing the system safely. Maintaining the integrity of the system by minimizing duplicate keys, or master keys, is imperative to the safety of workers and equipment.

KIRK® keys are proprietary designs only available through KIRK®. We maintain records dating back to the 1940s to ensure that duplicate key codings are not provided for a different interlock safety system at the same location. Click through to see the keys available.
