Trapped Key Safety System

Dold Trapped Key Mechanical Interlock Safety System A trapped key system uses a series of mechanical locks and keys to control the access of gates or doors to running equipment or machines, ensuring safe access to those machines. Dold Trapped Key System Gate Sets provide a full trapped key safety system, in one- to five-gate sets. They are available in either standard (SX) or solenoid-locking (ZRH) versions. All keys and their corresponding receivers and modules are unique within a set.

  • Systems are set up in a predefined sequence, preventing accidental access to running equipment
  • An operator must shut down machinery and lock it down, then remove the key and use the same key to unlock the door or doors that access the machinery.
  • Keys are trapped and released in a sequential order
  • The trapped key system is cost-effective for multiple locks over a large area and eliminates the cost of running electrical wiring over long distances.

Also available are tongue key actuators (purchased separately from the gate sets), and optional items such as door actuators, captive safety key sets, key modules for key exchange box setup, and mounting plates. Interlock safety switch body, coded trap key modules, coded keys, and tongue (key) gate actuator modules are all 316L stainless steel.

Trapped key interlock switches start at $1,019.00 and are in-stock for same-day shipping.
