I bought these and they are bolt down style and worked perfectly with the XS Power D3100 and the screws and washers that came with it. They have 4 1/0 gauge inputs. I also bought a pair that has 6 inputs and I am using those in the rear as pos/neg distribution blocks. I highly recommend these they are very well made and are good space savers.View attachment 26550428
