Product Details:

  • Designed for year‐round, outdoor use or temporary use requiring constant installations and take downs.
  • Heavy‐duty 16AWG SPT‐2 wire is robust enough for commercial use, but light enough for easy installation (about 1/2 the weight of the 14AWG cords).
  • PVC encapsulated weather-resistant sockets with brass contacts are resistant to UV sunlight exposure.
  • Sockets are designed to ensure a snug, weather‐resistant seal around lamp bases. You must keep a bulb in every socket to maintain weatherproof quality.
  • Two-prong fused 8 Amp male plug (31-, 56, and 100-ft cords only).
  • Cord can be cut for hardwiring (voids any warranty).
  • Install with sockets facing downward.
  • For spans longer than 25 feet, use a steel cable guide wire.
  • Socket has two mounting ears built into each side of the base. For long-term reliability and easier installation, we suggest using zip ties on each side of the socket. Read more about How to Hang Outdoor String Lights.
