      Helpful Information

      The 25-foot cords come with male and female plug ends and can be connected with other 25-foot cords up to two (2) in series. The 50 and 100-foot cords come with a single male plug. We suggest you connect them from a centrally installed splitter in a T formation. The 1000-foot spools do not come with plugs, but we carry male and female gilbert plugs in our installation hardware category.

      SPT-1 and SPT-2

      SPT-1 and SPT-2 is a rating of the insulation thickness of traditional 18 AWG C7 and C9 cords. SPT-1 is the type most commonly used by commercial Christmas light installers. SPT-2 is thicker and tailored to harsh weather conditions. Gilbert plugs must match. Read more: What is the difference between ST-1 and SPT-2?

      Common Sense Alert

      Important Note regarding 1000-foot spools: You cannot hook up all 1000 feet in a continuous run of lights but must cut it into at least four sections of 250 feet or less - less for higher wattage incandescent bulbs. Do not exceed 250 feet of 18 AWG wire in a single circuit, no matter the kind of bulb you are using, and do not exceed 1000 Watts per standard household breaker. Please consult with a Master Electrician as you design and install your project.
