The Squids ® 3194 Hand Tool Tethering Kit includes a 3156 Coil Tool Lanyard with Single Carabiner and the 3740 Hand Tool Attachment Trap - Slips ™ Variety 4-Pack. This tool tethering kit allows you to tether four different sized screwdrivers and hex key wrenches making it easy to use your tools on the job while preventing dropped objects when working at-heights. The 3156 Coil Tool Lanyard is more than just a small tool and hard hat lanyard. Built and tested to endure tough conditions and rated to support weight up to 2lbs / 0.9kg, the coiled lanyard is made with a low-profile design and durable plastic. With the lightweight aluminum carabiner on one end and a tethering loop on the other, it easily connects to tool anchors and attachments, even while wearing gloves. The coiled tether design reduces lanyard length to prevent snag and tangle hazards. The coil stretches from a compact 12in to 48in / 30cm to 122 cm. STRAIGHTFORWARD INSTALLATION No additional install tools or complicated taping or shrinking! The patented Slips ™ design requires a simple installation that follows its name. Simply slip the tool attachment on to the tool and connect the Squids ® 3156 Coil Tool Lanyard to complete your tethering system. Unlike competitors that offer a fitted cap that can cover up information (like on the end of a screwdriver, for example) these solutions leave the end open. The single piece design is easier to install compared to competitors that require two to three pieces to be assembled onto the tool. Simply poke the end of the hand tool through the orange interior membrane of the Tool Slip and slide the attachment to the desired location. The star points of the attachments interior will hold its location and the swiveling exterior ring will provide a connection point for tool lanyards. To remove the Slips™, simply push on the tab to loosen and then slide it off the shaft of the tool. No adhesive residue or mess will be left behind! PERFECT FOR SMALL HAND TOOLS Small hand tools have always been challenging to connect tool lanyards to. Screw drivers, small combination wrenches, punches, hex (Allen) wrenches and the like do not have captive connection points, and the low-profile designs can make it difficult for tapes, shrinks and tails to be applied. The Squids® Hand Tool Slips™ allow you to tether tools up to 1lb. based on their diameter. Four sizes of Slips™ are compatible on tools with diameters ranging from 0.05 (1.3mm) to (12.5mm).
