CAT generator extension cords are designed for harsh outdoor conditions when you need a reliable power connection most. Each cable is manufactured using a solid fill extrusion method to minimize impact from being dragged across rugged surfaces. While staying flexible in cold temperatures, the heavy-duty STW outer jacket is also heat resistant up to 105°C (221°F), making it ideal for various weather conditions. Available in a 50ft. length, this CAT cord is equipped with NEMA L5-30 ends to plug into a generator’s 3 prong 125 volt receptacle.
