The NLG Spin Tether™ is the ideal solution for creating a secure tether point on a rotating, parallel-shafted tool such as screwdrivers or allen keys. It can be retro-fitted without the need for any additional tools to any tool with a shaft from 3.9-9mm – one size fits all. Simply fitted and tightened by hand, the patented device’s non-metallic content also allows the tethering of tools for use in metal-sensitive and non-conductive areas. The spinning ring delivers uninhibited tool movement through 360 degrees. The NLG Spin Tether™ is constructed from advanced polymers, combined with the unique SoftLock™ core, to provide years of grip performance in the harshest environments.
