Brophy 7-Way RV Blade to 5-Way Flat Trailer Adapter | Reverse Lockout Support

Bridge the gap between your vehicle’s OEM 7-way connector and your marine or recreational trailer’s 5-way flat plug with a secure, corrosion-resistant connection.

Part Number: F75FB 7-Way RV Blade to 5-Way Flat Marine Grade Nylon

Overview

This Brophy wiring adapter simplifies your trailer hookup by converting a standard 7-way blade-style vehicle outlet to a 5-way flat trailer connection. It is a high-quality solution designed for boat, utility, and personal watercraft trailers where the integration of standard lighting plus an auxiliary circuit for electric-over-hydraulic reverse lockouts is required.

R&P Service Insight

This is an essential piece of gear for boaters using trailers with surge brakes. Standard 4-way plugs cannot deactivate brakes when backing up; this 5-way adapter solves that common headache.

  • Marine Ready: High-impact nylon body won't rust or corrode in salt air environments.
  • Secure Fit: Full-length shell design eliminates "plug-wiggle" and prevents disconnection.
  • Safety: Ensures all trailer lights, signals, and reverse circuits remain fully compliant.

R&P Knowledge Hub

Compatibility: Fits all standard OEM 7-Way Round (Blade Type) vehicle sockets typically found on factory tow packages.

Vehicle / System Fit: Universal for trucks and SUVs equipped with a 7-way RV blade port.

Installation Notes: True plug-and-play. Ensure the vehicle's 7-way spring cap latches over the adapter's molded ridge for maximum security during travel.

Performance Insight: The extended shell design is critical for trailers that experience significant vibration or bumpy road travel, providing more surface area for the vehicle's latching mechanism to grip.

Brand & Fitment Note

Selling Brand: Brophy (Distributed by R&P Carriages)

Application Reference: OEM names or trailer brands like EZ Loader or ShoreLand'r describe compatibility and fitment targets only.

What This Means: This listing is for a genuine Brophy adapter designed to interface with factory vehicle sockets and marine-style trailer plugs.

Before Ordering: Verify your trailer has a 5-pin flat connector (typically with a blue wire) and your vehicle has a functional 7-way blade socket.

R&P Repair Insight

Before ordering, perform a quick visual inspection to ensure this matches your specific trailer configuration. Marine trailers with surge brakes almost always require this 5th pin to function in reverse.

  • Check Pins: Confirm your trailer plug has 5 pins in a row (usually 4 female and 1 male).
  • Visual Inspection: Clean any existing corrosion from your vehicle's 7-way socket before inserting the adapter to ensure a solid electrical connection.
  • Storage: Store the adapter in a dry location when not in use to extend the life of the copper contacts.

Features
