Lightweight, extremely durable Squids 3011 Retractable Lanyard with Tool Carabiner + Swivel Anchor Carabiner can tether tools weighing up to 0.5 lb for full retractable functionality (or up to 8 lb for drop-protection only); and like all Squids Tool Lanyards, its low-profile retractable design minimizes the potential for snags, tangles and tripping hazards. Textured to provide a better grip, its durable, ultra-strong ABS plastic housing is designed to protect the internal workings of the retractable mechanism, and the housing's tapered cord exit limits the potential for debris being retracted back into the housing when the cord retracts. A handy trigger switch on the top-side of the housing also allows the user to easily lock the cord into a range of fixed lengths and\/or quickly release the cord to remove tension or to fully retract it. An included aluminum tool-tether carabiner with a double-action, self-locking gate allows the user to quickly connect to tools, and a second similarly designed anchor-point carabiner with a swivel end makes it easy to hook into D-rings while minimizing tangles and awkward working positions. The high-strength, cut-resistant Dyneema cord features a protective sleeve to reduce wear and tear to ensure a long, reliable use life. For added safety, the cord also features a red-colored impact-indicator which is revealed when the system is exposed to forces exceeding 110 lb, to ensure that the wearer is aware when tool drops occur. All Squids Tool Lanyards are built to withstand pre-defined weight limits and make it easy to avoid accidentally dropping objects that could cause unwanted damage or serious injuries. When working at-heights, it's critical to tether your tools, so do it right with Squids tool lanyards. Third-party certified to a 2:1 safety factor.
