Satin silver finish * Converts 4 gauge wire to an 8 gauge pin * Can be used with some amplifiers as direct inputs (I.E. amplifier accepts 8 gauge power wire, but you want to use 4 gauge. Depending on how close the power and ground inputs are together, you might be able to use this piece to convert from 4 gauge to 8 gauge. The key is that there is enough distance between the power and ground connections that when using these terminals, they do not touch) * Allen head set screw * Very heavy duty - Can be used for audio, marine and any under hood wiring
