The complete SAFEBLOC TENEX-TEC ULTRA SLING lowering set is designed for heavy-duty arborist rigging, particularly for lowering branches and trunk sections during sectional tree dismantling.

The set consists of a NOTCH SAFEBLOC friction device and an adjustable ULTRA SLING made from durable 12-strand SAMSON TENEX-TEC rope. The system of spliced eyes allows the length to be easily adjusted to the diameter of the trunk and installed without a carabiner, shackle or other metal connector.
