Blue Sea builds nice stuff!
You end up spending a little more for a Blue Sea product but they almost always offer a high quality part you won't have to worry about. This terminal block is made from a better-than-most plastic that doesn't split or crack when fastening it down. The terminal screws hold and don't strip out easily. It's amazing how fast the cost of a wiring project can balloon out of control but using quality parts will provide a safer system than running generic "unknown" parts.

Why so many Mounting Holes?
It is a nice, robust, sturdy terminal block. I purchased the 30A configuration. I gave it 4 stars rather than 5 because each side has 3 closely spaced mounting holes. Seems like overkill, and I was a little concerned the thin sidewalls separately the holes might crack. I fabricated rectangular "washers" that allowed me to use only the center holes on each side, and it greatly increases surface area to ensure there is no cracking.

Smaller than I thought
Nothing wrong with the terminal block, but smaller than I thought. I use 14 gauge wire with heat shrink ring terminals everywhere in my boat. The ring terminals have a hole for a #10 screw. I use this size because of varying terminal block sizes on my boat, and this size is always big enough. Unfortunately, there was not enough room to get my ring terminals to fit in this block. Some filing was necessary to get them to fit, but I finally succeeded. I think the specifications for any terminal block should include wire gauge typically used for the block, and maybe the screw size.
