Duplex Lock Box

Duplex Lock boxes are utilised to provide high level electro-magnetic lock security protection, associated with points and level crossing operations.

Where points are located in advance of the MLI, a Duplex Lock will be provided (released by Operators/safeworking Key and releases key for the frame or single lever).

Operation of the Duplex Lock will place the MLI to stop to qualify the level crossing approach.

Reclearing of the MLI to occur under two conditions as follows:

  1. When the Duplex Locks are restored and the track circuits are clear, (i.e. the train has left or is wholly within the loop).
  2. When the Operators push button is pressed.

High quality unit, constructed from 316 stainless steel, engraved inner door.
