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.

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.

Used it in a marine application and it was excellent splice box for 3 conductors of #10 wire.

The product is waterproof and easy to install!

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.

would not fit my wire

Needed a waterproof junction box for our fountain pump connection. Everything about this unit is excellent except for the screws to mount top plate. I used 4 different philip head screwdrivers and all slipped on screw heads! Adapters for wiring were easy to install - didn't use the wiring block supplied [used Wago connectors].Had the screws been better this would have been a 5 star review - I got around this issue and junction box works very well.
