The Rope Logic Ultra Ring Sling is the pinnacle of rigging slings. Simply pass the ring around a trunk and through one of the pockets in the sling to create an ultra-strong rigging point. Each sling is made with a Notch Rigging Thimble, which has a large, gentle bend radius, and a huge breaking strength. Choose between industry-standard Tenex-Tec or for especially large rigging jobs, Tenex-Tec Pro which is 20% stronger and solution-dyed for long-lasting color. Ultra Slings are measured by useable length as each sling has a short, spliced tail without a pocket. Each sling features a durable Notch Rigging Ring that is purpose-built for the arborist industry, with an ultra-wide bend radius and a silky-smooth non-anodized aluminum construction. These slings are made with the industry-standard Samson Tenex-Tec line, but are also available with the new Tenex-Tec Pro line. 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. 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.
