Adjustable CableGuard

A simple yet effective product that improves the reliability of the rail network, through reduced signal and power failures.

Building upon the success of the original (rigid) CableGuard of which over 1,200,000 units have been sold worldwide, the new adjustable design accommodates most rail types and allows for the use of cable ties. The adjustable CableGuard is also available in a flame-retardant material for underground/tunnel applications.

The Adjustable CableGuard has been developed as a “fit and forget” product, to prevent track circuit failures by the creation of an insulating layer between the rail, sleeper and cable.

Technical Features

  • Highly adjustable
  • Product designed for over and underground application
  • Option to Secure Cable Ties
  • Improved electrical insulation


  • The simple to use 2-part design enables the product to be installed in seconds without the use of tools.
  • The adjustable CableGuard secures cables closer to the sleeper than alternative models, reducing the risk of the cable moving and enabling efficient and professional cable routing.
  • By securing and protecting the cable, cable wear through sleeper and rail abrasion is prevented. This advanced protection reduces the risk of signal and power failures leading to a reduction in downtime and costly maintenance.
