Sirius Bull rope is a professional rigging line which has been trusted by arborists in Europe for many years. At 12mm, this 100% polyester double braid is slightly smaller than 1/2”(true half-inch lines are 12.7mm) and is a lightweight, high-performance rope. Unique to Sirius rope are the overload indicators: strands set at regular intervals in the rope which show when the rope has been subjected to overload.
