Rope Logic Ultra Slings are the most well-reviewed rigging sling in the arborist world. There is no faster way to set a rigging point than by wrapping your ultra sling around a limb or trunk and passing it through one of the pockets. The new Tenex-Tec Pro line is especially designed for large rigging jobs. Samson Tenex-Tec Pro is more durable, solution dyed, has an arborist-specific construction including a custom twist rate and a roughly 20% increase in strength across all sizes. 8 in. eye loop, 11 5 in. pockets. Rope Logic products are rigorously tested in accordance with a 3-Sigma Process, which provides a much more accurate MBS rating than standard testing processes. MBS: 9,900 lbs. Material: Polyester.
