The Carwires PBS8 8-AWG crimp barrier spades are designed to provide a secure, crimp-on termination for 8-gauge power and ground wires. Each crimp barrier spade includes a color-coded rubber protective boot. We recommend using a crimp tool to get achieve a long lasting secure connection between your wires and these terminals. All terminals are platinum-plated and constructed with 100% solid brass for the best possible connection.
