Power Cords, Power Cables,

Is it safe to use your extension cables outside? Most extension cables are built for indoor use only. While leaving them unplugged out in the rain won’t ruin them, the added wear and tear will render your extension cord unusable in only a short time. There’s also the risk of fire or electrocution if a wet cable is handled before the plug is allowed to dry. Whether you’re powering your hobby or your livelihood, it’s important to invest in safe, reliable cables like the ones you can find on that are intended particularly for outdoor use.

Watertight Extension Cables

Whether you’re operating your power tools for some overdue landscaping out in the front yard or putting in some work on that old boat on the dock, it’s important to be using the right power cord. Light-duty extension cords are intended only for use inside the home, and extensive exposure to the elements adds to the wear and tear on your equipment. A proper outdoor extension cable is essential if you intend to get the most out of your gear, and for playing it safe besides, reducing the odds of fire or electrocution. It's important to exercise caution when working with electronics in wet environments, and just as important to make sure your tools are the right ones for the job. Before you get down to work on that big project, shop at for watertight extension power cords in a variety of lengths and voltages.
