WISKACOMBI 308/5/W Enclosure, IP66, Junction Box, 51 mm, 85 mm, 85 mm, PP (Polypropylene), White (5 pieces)

You can't go wrong with these.

One of the best IP rated boxes that I have used.The lid is a close fit with a screw at each corner to lock it into place thus helping to keep the inside dry.When I use these, I always drill a small hole at the bottom so that 'if' water did manage to creep in, it has somewhere to get out.My second method of keeping everything inside dry is to run silicone around both sides and along the top (not the bottom).There's plenty of space on the inside for most common connection jobs ie security lighting.5/5 from me.

Do what they need to although I'm not quite so keen on the mounting mechanism compared to other similar products I've used.
