Simply insert stripped 4-gauge wire into each end of a coupler and tighten the connections with set screws. Heatshrink covers are included to help protect each connection against moisture, dirt, and corrosion.

Product Research


Overview: Each of these couplers attaches two 4-gauge wires together, end to end. They are solid brass with a nickel finish. A T20 Torx driver is needed to tighten the screws holding the wires in place. The included heat shrink tubing is then used to protect the couplers from shorting.
