13A weatherproof single socket extension lead (RCD option)

  • Sale
  • Regular price £19.49

Whilst standard DIY store extension leads are manufactured from plastic connectors and cheap, easy to damage PVC cable, these leads are in a different league. They are carefully constructed in our workshop from the highest quality and most robust cable and plug/sockets available. The H07RN-F rubber cable is specifically manufactured for harsh environments and its safety and performance under extreme conditions simply cannot be beaten.

Available with or without an in-line 30mA RCD (weatherproof IP66 rated for use outside). Extension leads without an RCD, MUST be connected to an RCD socket if used outside.

Please note that the socket is not compatible with the 13A plug fitted to many electric vehicle (EV) chargers. Please see our specific EV extension lead.
