13A weatherproof single socket extension lead (RCD option)

  • Sale
  • Regular price £19.49

This lead is designed to connect appliances with a standard 13A UK plug. It is not compatible with plug RCDs (an RCD plug is much larger than a standard 13A plug, and will have test/reset buttons) or 16A European plugs. Please see our extra large 13A UK socket or European extensions.

Perfect for heavy duty high current applications, such as powering items in the garden, including lights and heaters. The weatherproof socket's IP66 rating means that it remains watertight, even when subject to powerful water jets from any direction. Unlike any DIY store extension leads which are often sold as 'weatherproof', this lead can actually be used for prolonged periods outside. 

Available with no RCD, plug RCD or an in-line RCD. See our guide Do I need an RCD?, to ensure that you purchase the correct lead.
