Product Details
The Rockville MFG20B provides long-run grounding for marine audio systems, car amplifiers, and solar installations using true 4 AWG tinned OFC cable. Its 20' length is suited for larger vehicles, boats, amp racks, battery compartments, and distributed power layouts needing reduced voltage drop and corrosion resistance. The black heavy-duty marine-grade PVC jacket stands up to saltwater, moisture, heat, cold, oil, gas, and fumes, while 1,862 strands support flexible routing. A pre-installed ring terminal, black mesh split loom, ferrules, heat shrinks, grommets, and zip ties create a protected, organized installation rated up to 150A at 20'.
