Lightweight and durable, the SafeBloc has no moving parts to wear out or damage, and is hard-coated for extended wear.
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.
The Notch SafeBloc can be used anywhere you might use a rigging block. The amount of friction used can be adjusted by weaving the rigging line through fewer or more holes in the SafeBloc.
