Stop worrying about frozen and burst pipes this winter! This MAXKOSKO self-regulating heat cable is your solution. The 50-foot length (that's just the heating part, plus a 6ft power cord) can protect a long run of pipe. It's 'self-regulating' – that means it automatically adjusts its heat output based on the surrounding temperature. Colder spots get more warmth, warmer spots get less. This prevents overheating, saves energy, and is safe for both plastic and metal pipes (up to 2-inch diameter). It works down to -40°F and starts heating as soon as you plug it in (a little indicator light turns on). Installation is a DIY project: you can wrap it in a spiral, run it straight along the pipe, or even overlap it, then secure it with the included fiberglass tape. Perfect for outdoor spigots, RV water lines, crawl spaces, basements, or drain pipes. A little effort now can prevent a huge, expensive repair later.
