Wiska - LEDJOY IP68 Gel Filled Junction Device c/w 2 and 3 Pole Connectors

I bought this after trying 4 box and terminal block alternatives that didn't work - it did the job. You need to get the cables the correct length so everything is where it should be and I'd recommend allowing some time for the gel to move before submersing and then checking the seals. Also make sure the end clips where the cables enter the junction box are engaged. You may need to do this manually as there isn't a clear click, unlike the clips on the body
