Sirius Bull Rope has been a must-have for arborists. This is why we expanded and upgraded our Bull Rope line. What's new are the transverse stripes in the cover pattern which indicate when the rope is overloaded. In addition, our Bull Rope series now also includes 18 mm and 20 mm models. The various diameter versions can now be distinguished easily via differently coloured tracer threads. Sirius Bull Rope continues to be a highly abrasion resistant and easy to knot rope offering unmatchable value for money. Machinery Directive 2006/42/EC.
