Safety is the top priority when users are working on live parts. With the tool set including the ratchet wrench, T-handle adapter and nut driver, electricians and electrical specialists are ideally equipped for work on electrical systems. Thanks to the ratchet wrench with left or right rotation provided, changing nut drivers is child's play. By pressing the release button, the nut driver inserts are mechanically locked. To enable users to react to different situations, the T-handle adapter electric is also included in the set. This enables even deep-set screws to be reached effortlessly. The selection of nut driver inserts with hex screws, hexagon head screws and extensions offers the user the required degree of flexibility when working. The ratchet wrench, T-handle, nut driver and extensions are organised and neatly stored in a practical and sturdy case. Each tool in the set is subject to an individual piece test as per the international IEC 60900 standard, allowing users to work safely on live parts up to 1,000 V AC.
