Waterproof Junction Box, 3 Way Outdoor Cable Connector ​IP68 Junction Box Electrical Junction Box for 5-15MM Diameter Cable,2 Pack

I particularly like the fact you can connect a armoured cable to a standard cable with the grommets, it’s waterproof

Second time I’ve bought this. Does what it says.

I needed waterproof small boxes for a fence lighting installation using 10mm corrugated conduit over the cable for additional protection. Boxes had to be small to fit into the existing gap and I wanted a truly waterproof box no leaks. These ones tick all the boxes. The glands fit a wide range of diameters between 4 and 15mm using rubber adaptors - I have managed to fit the tightest one and it looks really waterproof. The box itself is sturdy and the enclosure closes properly (the opposite than the latest ones which I just return) The box is small but sufficient for a 3 way connection: 2 to both sides and 3rd one to the light drilling on the back of the box and sealing around with silicone on the back of the fence panel. It took me days to find the perfect match but it eventually happened!!

This is the best outside connector I have ever had. Does the job well.

Returned ordered in error, but arrived quickly and was as stated.
