The Squids Tool Lanyard with Double-Locking Swivel Carabiner is part of an overall fall protection plan to reduce the risk of falling objects and increase workplace safety. When working at heights, it's essential to tether tools. High-capacity lanyards are a piece of safety equipment designed to attach one end securely to a fixed anchor point, and the other to an appropriate attachment point on a tool by proper tethering. These tool lanyards are built to withstand defined weight limits and made easy to use by any worker to avoid accidentally dropping objects that could cause unwanted damage, injuries, or possibly death. The advanced technical design of the 3139 tool lanyards uses a heavy-duty, single-length, non-shock absorbing webbing. There is two swiveling double-action locking carabiners on both ends of the tool lanyards with captive eyes for maximum security. All double-locking lanyards are rigorously tested and third party certified to a 40 lb. maximum capacity with a 2:1 safety factor to prevent falling objects. When working at heights, choosing the best tool tethering equipment matters because there are no second chances.
