Notch SafeBloc
The Notch Safebloc is a revolutionary rigging tool that adds friction to the rigging system at the top of the tree. That added friction increases safety by reducing the forces on the anchor point. It also increases convenience and efficiency on the job by allowing the climber to assist with lowering after the initial drop. Use the Safebloc in any configuration where you would use a block or pulley for rigging. You can change the amount of friction provided by running the rope through only one hole, two, or even through all three for maximum friction.
Rigging sling of your choice sold seperately and can be found here. Just add an order comment directing us to splice in the Safebloc!
Details
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.
Use the SafeBloc anywhere you'd use an arborist block for lowering. The rigging line can be woven through the three holes for its maximum friction, or fewer holes for less friction. However, the climber should not have to travel back to the SafeBloc to do any adjustments; just pick the friction level predicted and continue to use it. The SafeBloc does NOT add significant friction. A device that added too much friction could be dangerous and fatigue the short length of rope between the SafeBloc and the material being lowered. You can use the SafeBloc without a basal lowering device on small-to-medium loads, but once you get to medium-and-above size loads, it's time to add the basal lowering device.
Lightweight and durable, the SafeBloc has no moving parts to wear out or damage, and is hard-coated for extended wear.

For aerial friction, this is wonderful. The Notch SafeBloc works great, albeit a bit heavy. You can do quite a bit without a porta wrap with this up in the tree. I'd love to see a system that is midline attachable for varying degrees of friction in the future. I'd buy that for sure. Aerial friction is extra helpful when youre working dead trees or pretty weak trees.
