Have you ever been merrily driving your router along when suddenly you run out of power? The extension cord gets hung up on something, and suddenly you’re disconnected. I know, the time-tested solution is to tie a knot in the cord that captures the plug and extension cord. (What is the right Scout knot for cords?) For a mere $5 you could try a Cord Snake instead, and never again worry about getting disconnected, or tying the right knot.
The Cord Snake is a simple device that acts like a bridge between the extension cord and tool. It works on cords from 10 to 18 gauge. It’s easy to leave it permanently looped on the end of an extension cord so it’s available to grab the cord of any power tool you’re using.
