Squids 3713 Elastic Loop Tool Tails with Two-Piece Swiveling D-Rings act as a handy retrofit attachment point for a wide variety of tools, to minimize the potential for dangerously dropped objects when working at heights. Heavy-duty nylon webbing is double-stitched with high-tensile-strength nylon thread to ensure reliable performance in even the harshest work environments. Built for versatility and secure, always reliable tool tethering, these tails feature a stretchable nylon loop with an adjustable barrel lock on one end and a corrosion-resistant, two-piece swiveling D-ring on the other. Once the loop end of the tail is secured to a tool or anchor point, the D-ring acts as a captive hole for hassle-free tool-lanyard attachments. By allowing for seamless rotation, the swiveling mechanism helps prevent the overall tool-tethering system from getting tangled or bound up. For best results, always reinforce the loop end of the tool tail with Squids 3775 Self-Adhering Tool Traps or Squids Cold-Shrink Tool Traps (tool traps sold separately). When working at heights, it’s essential to tether your tools, and these tool tails 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. When used properly, Squids 3713 Elastic Loop Tool Tails are third-party certified to a maximum tethering capacity of 10 lb with a 2:1 safety factor.Note: This is a non-returnable item.
