Klein 1000 V Insulated Tools

All Klein insulated tools comply with ASTM F-1505 and IEC 60900 standards for insulated tools and are clearly marked with the official international 1000-volt rating symbol.

Each insulated tool is put through Klein’s internal rigorous testing process to ensure the tool can handle any situation in the field. Some of these tests include the dielectric test, a handle pull-off test, an impact test, and a flammability test to confirm the durability and reliability of our insulated tools.

Not all tools with plastic coatings or plastic handles protect against electrical shock. Only use those tools marked with the official international 1000-volt rating symbol, as shown, if there is any chance that the tool will contact an energized source.

Klein Tools

Since 1857, Klein Tools has been manufacturing tools in America, and it’s as important for the Klein family to keep that tradition now, as it was more than 150 years ago. You see, Klein isn’t just the name of our company; it’s also our family name, so we have to be proud of everything we make.

Klein Tools continues to invest in U.S. manufacturing and is committed to maintaining its place as the favorite among electricians. Klein is the only major tool manufacturer worldwide focused on electrical and utility applications. No other manufacturer of hand tools and related products used in electrical applications makes more items in America than Klein Tools.
