Custom Truck One Source has blocks for numerous job-specific applications. Browse our inventory to find a specialty block that offers the most effective way to distribute conductor wire with the equipment you plan to use. Our specialty block options include:

  • Helicopter blocks: A helicopter block guides conductor wire as the crew feeds the pilot line from a helicopter. The blocks incorporate features that prevent the line from sliding out of place.
  • Jib rollers: A jib roller attaches to the boom arm on a bucket truck, helping crews distribute overhead wire from the ground.
  • Radius blocks: A radius block is a versatile tool that works for numerous applications. These blocks provide minimum bend radius protection when distributing wire like Aluminum Conductor Composite Core (ACCC®).
  • Static blocks: A static block distributes the static overhead wire that prevents excess energy buildup by dispersing energy from lightning strikes.
  • Uplift blocks: An uplift block has features that pull the conductor wire downward during uplift situations where the conductor begins to lift out of the block’s groove.
