3 Things to Know About SJTOW vs. SJTW Extension Cords

SJTW is fine for most outdoor use For normal yard work like hedge trimmers, string lights, or an electric mower, plain SJTW is perfectly fine. The “W” means weather-resistant, which is what matters for rain and UV exposure.

SJTOW adds oil resistance The “O” in SJTOW means the jacket resists oil, gas, and chemical spills. Use it near cars, generators, or gas-powered tools to avoid a brittle or cracked cord.

Check for the “W” stamp Both cords are outdoor-rated, but only the “W” guarantees weather resistance. Don’t buy an outdoor cord without it.
