The Radians Retractable Tether System includes a heavy duty and a multipurpose surveyor vest, eight made-in-the-U.S.A. retractable tethers, and a tool lanyard attachment accessory for tool changes. The system prevents objects from dropping, as well as keeps tools securely contained in heavy duty grommeted anchor pockets inside the vests when tools are not in use. The tether system can accommodate pencils and pens, cell phones, tablets, hard hats, tape measures, small radios, and tools up to 2 lbs. Radians' retractable tethers meet the ANSI/ISEA 121-2018 standard for dropped object prevention solutions.
