IP67/8 Waterproof Electrical Junction Box Cable Connector for Underwater or Underground, Cable Range Ø0.14-0.39Inch(3.5-10mm) 2 or 3 Pole 4PCS

I haven't deployed this outdoors yet, but it's nice that the 4-pack comes with the wire stripping tool and screwdriver and it looks like it should hold up ... I'll put it outside in the mud soon, and we'll see how it holds up.EDIT1: my 22AWG stranded wires pull out of the screw terminals very easily. I compared the screws to a similar product which has a stronger mechanical hold on the stranded wire (Kehrbid 2-Pack Waterproof Junction Box) and the image is attached. The one on the left, with a concave end is this product (weak hold on stranded wire) and the one on the right is the other product (much stronger hold on stranded wire). Lowering the review to 3 stars since I'm no longer confident that the wires will stay in the screw-terminal long-term.EDIT2: There is also a plastic burr on at least one of the screw threads right next to the seal (adding another image).

Work well and a great solution to the common problem of cut or damaged extension cords. They are a very tight fit and are a bit fiddly to install.

It was exactly what I needed to connect my new ceiling fixture to hanging wire. I can’t comment much on its water resistance. It came with small rubber washers that can be used to tighten seal on each end where the wires come out.

This product was exactly as described, easy to use and worked great. Came with everything needed including instructions.

The terminal screws are a bit tedious but overall worked well.
