Arborist Rigging Blocks and Pulleys

Arborist blocks are built to sustain shock loading, a situation where the load free-falls momentarily before being caught by the block. This places far more force on the hardware than normal lowering. Arborist blocks have widened cheek plates to protect ropes & an upper sheave to safely attach a rigging sling. Pulleys are not manufactured to handle shock loading and do not have the features necessary for use in tree rigging.
