Product information

Our Italian made transmission helicopter bundled stringing blocks are manufactured by TEMA with moulded Al. alloy sheaves on ball bearings. Available also with nylon lining sectors to protect the conductor throughout stringing operations, we utilise a galvanised steel frame for greater wear and tear in the field. These heavy duty rollers come standard with a clevic attachment as well as a pilot wire holding bracket and detachable wire guiding rod.

Single pulley versions are also available.


  • Standard with nylon sectors and clevis attachment
  • Optional grounding device upon request
  • Replacement nylon and Al. liners available
  • Different spacings and offsets between sheave centres available
