TetherLock is a tethering system that allows industrial climbers to secure their tools efficiently and safely. By storing unused tools on a base connected to the harness and tethering only the actively used tools, TetherLock streamlines tool handling and reduces clutter. At the core of this is the TetherLock mechanism. The mechanism is integrated into the tools, allowing them to be easily switched out of storage and into active use, and vice versa, in a matter of seconds. During this process, the tool is always connected, which makes it impossible to drop and ensures maximum safety.
