The future of rigging is here, brought to us by David Driver of X-Rigging Rings. Notch Equipment and David worked together to develop a revolutionary friction tool for rope rigging work called, SafeBloc. SafeBloc is a triple hole thimble that adds friction in the rigging system to the top of the tree, thus adding safety by reducing rigging point stress, compared to a system that uses a block or pulley. Also, with the benefit of friction, the climber can often take over on the rigging line AFTER the groundperson controlled the initial drop. This is true on small-to-medium loads. This frees up the groundperson to use both hands and the climber can FINISH the lowering. Lightweight and durable, the SafeBloc has no moving parts to wear out or damage and is hard-coated for extended wear. Rope capacity for 3 Hole inner diameter is 3/4 in. outside groove is up to 24mm.
