The Tramontina PRO IEC 60900 insulated tool line offers total safety for those who work with electricity. Recommended for activities of low voltage up to 1000 volts on alternating currents and 1500 volts on direct current. The tools follow the requirements of the IEC 60900 international standard (equivalent to the EN 60900 European standard). The line offers a complete line from combination and open end wrenches, ring spanners, adjustable wrenches, sockets and accessories, pliers, screwdrivers and nut drivers, mini hacksaws, cable strippers, and tool cases.
