Parts Desk Insights
Best Use Case: Best for marine wiring runs where you want a flat duplex cable that stays flexible and is easier to route neatly than round cable.
Common Issues: For best results, plan your cable path before installation (flat ribbon cable can be sensitive to sharp bending in tight corners). Also ensure you’re using marine-appropriate terminals/splices that match bare-copper conductor preparation so connections stay corrosion-resistant.
