The Squids 3109F(x) Tool Lanyard with Locking Swivel-Action Aluminum Carabiner + Loop features a patented design that prevents falling objects while absorbing any dynamic energy that might be transmitted through the lanyard's length to reduce any torque that your body, or anchor point, might experience if a drop occurs. By reducing this shock load, this tested and approved design prevents the tool from pulling the user down with it, effectively protecting all involved, both those above and those below. Durable, low-profile 1680 denier polyester, elastic-blend webbing with high-strength, three-ply nylon stitching on both ends ensures secure, reliable, lighter-weight performance, and the lanyard's single-length format eliminates the potential for the weak points commonly seen on multi-component lanyard alternatives. On one end, an anodized aluminum-alloy swivel carabiner with an easy-grip, ergonomic format and double-action locking gate makes it easy to attach to tools or anchor points, even when wearing heavy work gloves, and its inherent captive-eye attachment point helps the user better predict the direction of loads to minimize the potential for the lanyard hooking into the carabiner's gate as well as the potential for other related, dangerous lanyard issues. On the other end, a secure-grip treaded loop allows the user to reliably attach the lanyard to themselves, to a wide range of tools (large and small) or to various sorts of fixed-structure anchor points. When working at heights, it's essential to tether your tools, and these tool lanyards are built to withstand defined weight limits and can easily be used by any worker to help avoid accidentally dropping objects that could cause extensive property damage and serious, potentially deadly injuries. This tool lanyard is third-party certified to a 25 lb maximum working capacity with a 2:1 safety factor.
