Product Description

The Rockville MFG20R supplies long-run power transfer for marine audio, car amplifier, and solar panel installations with true 4 AWG tinned OFC construction. Its 20' red cable fits larger boats, SUVs, trucks, battery relocation projects, and amp rack power layouts where current flow and corrosion resistance matter. The heavy-duty marine-grade PVC jacket is saltwater-proof, moisture-proof, and resistant to heat, cold, oil, gas, and fumes, while 1,862 fine strands keep routing manageable. Pre-installed hardware, red mesh split loom, ferrules, heat shrinks, grommets, and zip ties help build a polished, protected power path rated up to 150A at 20'.
