Parts Desk Insights

Best Use Case: Use this duplex flat cable for marine wiring jobs where you want a flexible, vibration-tolerant two-conductor run with a flame-retardant jacket and tinned copper conductors.

Common Issues: On boats, double-check routing and termination: confirm you’re using the correct duplex 10/2 layout (flat duplex orientation) at each end and that any connectors you select are compatible with stranded tinned-copper conductors and the cable’s insulation/jacket thickness.
