Tool Tethering Anchor Straps thread through railings, scaffolding, equipment and structures to create a retrofit attachment point to tether tools up to 40 lb. Anchor straps are designed to prevent heavy tools from falling when working at heights. Abrasion-resistant, polyester webbing and durable, steel D-ring provide heavy-duty strength to hold tools. Additional wear sleeve helps reduce wear-and-tear by adding a layer of protection against the elements and surface abrasion. D-ring acts as a captive hole to tether Squids Tool Lanyards (not included). Straps meet the ANSI/ISEA 121-2018 standard for dropped object prevention. They are third-party certified to hold a maximum 40 lb. with a multidrop safety factor. Straps are not for fall arrest.
