SOMELINE IP68 Waterproof Junction Box Outdoor Cable Connector, 2-Way Wire Connector Electrical Junction Box, Extension Electrical Cable Protector for Cable Diameter Ø5mm-9mm (2 Pack)

As specification. Compact and robust, good value.

I need to to extend my cable for my tree light so easy to.do

Really happy with these connectors. They aren’t small but their connectivity is really good and is definitely strong in the waterproof department. My one criticism is that the screw for the wire connectors are very small. Probably to accommodate the slim design of the connectors.

Good quality

Bought a pack of two to use outdoors to extend where I can put a security light. Very easy to use (make sure you are sure you're buying the right size for your cable or it just won't fit) and looks resilient. Make sure you have a very small cross head (Phillips) screwdriver to install. It's small, but I didn't find it fiddly at all to use. Just put the two retaining pieces on each cable, then screw in your wires (labelled on the plastic) and then tighten. I hand tightened the inner and outer (the outer clamps onto your cable). Only had light rain on it, but all fine so far. I might stick some clear sealant on it. I would not immerse in water for any period of time, as water gets into everything eventually. Think it took under 5 minutes to use and that included stripping the wire. Fwiw, I used to be an electrical engineer and I think it is fit for purpose. Really recommended and I'd certainly buy again if I need to repair or join a cable.

Good buy and good price

It can be a challenge to manoeuvre the wires into the screw holes, given that you cannot cut the outer sleeve back very far.

Got a 2 pack which is good value. Fairly easy to use. Although the terminals are quite small and fiddly. Would recommend.
