Parts Desk Insights

Best Use Case: Ideal for marine wiring projects that need a two-conductor duplex cable with excellent flexibility for routing through tight spaces.

Common Issues: For best results, verify the required cable type/rating at the installation location (UL/BC-5W2 and 105°C dry / 75°C wet). When routing, take care to avoid sharp edges that could damage insulation, and plan connector and strain-relief compatibility with flat duplex marine cable.
