Safe work on high voltage

Insulated up to 1000 volts

These spanners are specially insulated for work on high voltage installations. The insulation is tested to 1000 volts AC. This lets you work safely on live parts, provided you choose the right size.

Double ended for every job

Each wrench combines a ring end and an open end. This lets you grip both nuts and bolt heads. You determine the size you need by the across flats dimension. Choose the size that fits the nut or bolt, otherwise you may damage the insulation.

Strong and durable material

The wrenches are made from chrome vanadium steel. This makes them strong and durable. The hanging hole helps you store them neatly. Check the insulation for damage before each use. Never use them above 1000 volts.

These spanners sit within High-Voltage & Insulated Tools. If you are working with screws rather than nuts, look at Screwdrivers or Socket Bits. For a complete kit choose a Tool Assortment, and with Extensions you reach awkward spots.
