Brand New Blue Sea 5026 12 Circuit Fused and Ground distribution block.
It's awesome because it takes normal ATO/ATC fuses you can find anywhere. Screws are Philips head so no need to dig out that one hex key. Cover+labels. Would be nice an clean show piece for install or use it in your boat.
I was going to use it but never got around to installing it and trying to raise some cash to fund a different build.
