Central to the Squids 3193 Tape Measure Tethering Kit is the Squids 3100F(x) Tool Lanyard with Aluminum Carabiner + Loop. This lanyard's patented design 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 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. An anodized aluminum-alloy carabiner with captive-eye attachment point on one end delivers an easy anchoring option while minimizing the potential for lanyard tangles. A treaded loop on the other end securely grips the attached tool. The included Squids 3770 Tape Measure Trap allows you to easily keep your rule snug and secure. Just open up the hook-and-loop straps on the trap, place your tape measure inside, and then adjust and tighten the hook-and-loop straps to keep the rule secure. Once you have your tape measure in place, simply attach the trap's D-ring to your tool lanyard to complete your tethering system. Kit is third-party certified to a 2 lb maximum working capacity with a 2:1 safety factor.
