Fortress' mGard Modular Robust Trapped Key Interlocks for Heavy Duty Applications

Trapped key interlocking is a tried and tested method of mechanically
safeguarding dangerous machines and hazardous processes.

Solve your safety issues by selecting the required products in order of the steps shown here:
  • Power and Control Isolation
    Identify the energy sources to be isolated and/or any hazard that cannot immediately be isolated such as; heat, pressure, radiation or machine rundown time.
  • Key Exchange
    Identify the type and number of access points.
    The modular system allows the safeguarding of potentially hazardous areas without the need of wiring. All mechanical mGard configurations are also suitable for use in areas where explosive or flammable gases for dust particles may be present. Key Exchange and Door Lock Units can easily be extended with an extension module (XMA).
  • Door Locks and Actuators
    Identify the type of access point; part body or full body access doors with or without the use of personal safety keys (to prevent accidental lock in).
