True Mods Waterproof Ground Power Distribution Terminal Block Battery Bus Bar [Max. 300V AC/48V DC] [IP65] [Positive/Negative] Insulated Busbar Box for 12V Auto Vehicle Marine Car RV Boat UTV ATV

The box and wire seals are really well done, granted I don't think the seals would work down to the Titantic but "normal" use would work great.

Great positive terminal box for all your lights and accessories on your vehicle.

It's exactly what he needed

This works fantastic and its easy to install, but the clips that hold the lid on, are very brittle and will break off after time. I fixed it by tossing a zip tie around it and can slide it to one side if I need access, but it'd be a lot cooler if the clips wouldnt break.

Works well

I struggled to find components that were truly waterproof and this did the trick. It's bomber and well built. The included power feed wire is very thick, like 4ga I think? The only issue I had is that I am only running 8ga so the sealing gasket isn't snug. I will have to wrap my wire in tape at the sealing point to make it thicker.

Once I figured out what I was doing this was an easy install and a great streamlined upgrade to add more lights in the future without having to pay more for a separate wiring harness with each kit. Major space and clutter saver. Bought the pre assembled one and I'd definitely go with that one again. Paired it with their bussboard PDC and it looks great under the hood.

All of the included terminals are aluminum and the power cable looks like CCA but I think it's tinned copper.
