Helunsi Waterproof IP68 External Junction Box, 2 Way Outdoor Junction Box, Underground Plug Line Coaxial Cable Connector Wire Range 5 to 15mm Electrical Power Cord Weatherproof Junction Boxes - Black

Used this to replace my pool light without pulling a new cable so it will be submerged forever. I soldered the connections and then filled the box with a pourable silicone. Normally you have to pull the old cable (mine is 100ft) out but after 20 years it is almost impossible to break it loose and pull the new one through. The best price I found was $250 for the labor.Way easier and cheaper to use this j-box but if it fails it'll ruin a $500 light. Works great so far but just installed April 2024. I'll update this if there is any problem.

It was a little hard to work with but I like the features of the box

Pretty much a no brainer on how to setup and use this item.My only 2 cons would be that it is a chore to get a larger style cable (power cord) thru the sealing rings and into the box and I wish that were or was another mounting method.

Worked very well to splice an outdoor power cable for a septic system lift pump. The box is left above ground under a fake rock, so I have not tested the weatherproofing as well as some other applications might.

Had to repair Internet line to house, was cut during digging session. Worked great and is very well made.

I needed to cut and re-route speaker wire to a deck, there was almost no slack in the wire. This box allowed me to do a perfect in-line splice and box seems very well constructed and should protect well against the elements.

I needed a waterproof junction box to use in conjunction with a sprinkler control line repair. The junction box was perfect for my needs. I was impressed with the seals and overall quality of the junction box until I came to screwing the lid on the box. The manufacturer included the cheapest screws I've ever seen. One of the screws lacked slots in the head and was useless! My recommendation to the manufacturer is to get rid of the cheap screwdriver included and spend the money on higher-quality screws.

would not fit my wire
