Insulated Wire Cutter and Strippers for Working at Height Our collection of insulated wire cutters and strippers has been specifically developed for working at height safely. Each wire cutter or stripper includes a handy attachment point to tether the item to your harness or work belt. This simple feature is effective in preventing tool droppages and serious accidents occurring while working at height. Furthermore, their strong design makes them more than capable of standing up to extreme impact and abrasion, even in the most relentless of working environments. Built of solid metal and high-quality flame-retardant insulated moulding, these insulated wire cutters and strippers provide ultimate protection against electric shock and arcing up to 10,000 volts.
