The Squids® 3193 Tape Measure Tethering Kit allows you to tether one standard 2 lb/0.9 kg tape measure, making it easy to use your tape measure on the job while preventing dropped objects when working at heights. What's Included - The kit includes a Squids® 3100F(x) Single Carabiner Tool Lanyard and a Squids® 3770 Tape Measure Trap. Straightforward Installation -Connection points for tool lanyards are not always readily available on tools, which can create a hazardous environment while working at heights. Learn how to tether your tools using the products included in the kit here. No tape and tool tails required for this convenient tape measure tethering kit. Just open up the hook-and-loop straps on the 3770 Tape Measure Trap. Place the tape measure inside of the trap, with the back of the tape measure facing the D-ring on the back of the trap. Adjust and tighten the hook-and-loop straps accordingly. Attach the 3100F(x) Tool Lanyard to complete your tethering system. See full instructions for more details.
