Parts Desk Insights
Best Use Case: Recommend this adapter when a customer's tow vehicle has a 7-way RV-blade outlet but their trailer (typically a boat or utility trailer) uses a 5-way flat connector. It's the cleanest solution to avoid cutting or splicing wiring. Confirm the trailer's connector type before recommending — if the trailer uses a 4-way flat, suggest the Seachoice 7-to-4-Way Adapter instead. SKU: 177-E5415.
