No, you do not. The patent-pending Cobra Connector can be installed both above and below ground. The Cobra Connector is a patent pending connection system designed to make your lighting installations more efficient and secure than ever before. It is made with an improved clamp technology, making it 2x faster to install than other leading connection systems. The metal fangs pierce the jacket of the cable and create an indestructible seal using dielectric grease, shielding it from moisture, dirt, and other elements. The Cobra Connector is designed with an indicator light to improve troubleshooting throughout the lighting system. The indicator light will shine green once your connection is sealed and secured, making it faster to find the solution.
