Totally Brilliant Outdoor Junction Boxes
Used very many of these. Do not confuse with the similar snap-on version without screws. These much better. I use Wago clips rather than the included wire connector. These boxes take 20mm glands and are already threaded and super easy to use. Brilliant product.

A watertight case for purchase!
An excellent design, with threaded entry ways into a well sealed box. Just screw the cable glands in and it breaks the flexible seal forming a tight connection around the thread. Use the wall bracket or the separate corner holes, within a separated compartment from the main box section, to keep the IP rating. A quarter twist front panel means minimal effort to secure it. Make sure you use breathable glands, cap or fill with gel to keep everything water/condensation free! Recommended by product, great design!

Wiska boxes are great but not as described...
Wiska boxes are an electral mainstay. Best junction boxes you can get by far. Unfortunately these should have come with terminal blocks inside - thats what the 308/5 means. These were just plain 308. Boo supplier.
