The Auto-Connect L2RT21W is a high-quality ring terminal set designed for the reliable connection of 21 mm² / 4 AWG power cables in car audio and automotive electrical systems. The set consists of two closed ring terminals with different connection sizes—M8 and M12—and is therefore suitable, for example, for connections to the battery, ground, fuse holder, or power distribution block.

The cable lugs feature a closed crimp area that completely encloses the inserted conductor and, when properly crimped, provides a stable, low-resistance connection. Copper is used as the conductor material. The tin-plated surface provides additional protection against oxidation and corrosion, thereby ensuring consistently reliable current transmission.

An additional solder hole allows for additional securing of the connection if needed. The package also includes one red and one black heat-shrink tube. This allows the positive and negative wires to be clearly identified and provides additional protection for the connection area.
