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. The SafeBloc comes spliced onto a 3/4 in. Tenex from Samson. Tenex-TEC is a high-strength, low-stretch rope specifically designed allow higher production splicing for standard slings and Whoopie Slings. This construction also allows more rope surface conformance to objects being lifted than standard single braid constructions. Samthane coated to enhance its wear life.
