Review: Quality! - Worked out great. Blue Sea for the win!
Review: 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.

### ⭐⭐⭐⭐⭐ Quality!

### ⭐⭐⭐⭐⭐ Solid terminal block
*by D***V on March 17, 2021*

This terminal block is solid. I used them to redo the wiring on my boat. Have hot had a single failure and the connections run the amperage through in a safe and good looking manor. I'll be ordering a few more for extras.
