External IP54 13 Amp 240v Mains Outdoor Socket & 2 Way On/Off Switch - 204978
You get what you pay for.
The waterproofing is not that good and you can't leave the plug in the socket. I bought a "BG Nexus IP66 Weatherproof 1 Gang 13A Socket With External Switch" instead - far better quality.
Waterproof Gauntlet Gloves Long Heavy Duty Rubber PVC Coated 17' Size 9
Tough and long
Bought first pair a few years ago, now got some more. A generous size and well made.
