TEROWELL COUPLERS, available in both threaded & unthreaded versions, are used to make continuous connections between copper bonded earth rods. The material used in these couplers is gun metal, whereas clients can opt for bronze or brass as well. These couplers are available in two shapes, hex and round. With excellent oxidation resistance, our copper coupling electrodes are considered the preferred earthing equipment. This type of copper electrode consists of flat tube technology, copper connections and a crystalline mixture filled inside the electrode, ensuring an economical grounding system. Taking into account the different grounding requirements, these electrodes are manufactured in different sizes and specifications.
