M-BS Trapped Key Bolt Interlock – Single Key

Inquire now
  • The M-BS Trapped Key Bolt Interlock works on the principle that when the key is not present, the bolt is extended in the lock position with the guard closed.

  • To unlock the M-BS Trapped Key Interlock, the key must be removed from the isolation switch device and/or the key exchange system and inserted into the trapped key interlock.

  • Turning the key will re-tract the bolt, opening the guard and trapping the key in place.

  • Only when the guard is closed and the bolt is extended, can the key be released and placed back in the Isolator Switch or Key Exchange System.

  • Power can then be re-applied to the guarded area.

  • It is important that when the bolt is retracted, it is held captive until the guard is closed.

  • If you can extend the bolt whilst the guard is open, you are at risk of serious harm.

  • Skorpion Trapped Key Interlocks are manufactured in either mirror polished die cast or 316 stainless steel.

  • The internal mechanisms are constructed using stainless steel, ensuring long term reliability even in harsh environments.
