<h3>About RV Designer</h3><p><strong>RV Designer</strong> has been a trusted name in the recreational vehicle industry since 1993, when the company was founded in Wheeling, Illinois. What began as a manufacturer of drapes and window coverings for the RV OEM market has grown into one of the industry's most recognized suppliers of replacement hardware and accessories for motor homes, travel trailers, fifth wheels, and all forms of recreational vehicles.</p><p>Over more than three decades, RV Designer has earned a reputation for producing durable, reliable, and easy-to-install components that meet the unique demands of life on the road. The company's engineering and testing processes are built around the understanding that RV hardware must endure constant vibration, changing climates, and years of frequent use — standards that set RV Designer apart from generic hardware alternatives.</p><h3>A Complete Hardware Solution for RV Owners</h3><p>One of RV Designer's greatest strengths is the breadth of its catalog. Whether you're dealing with a worn-out latch, a cracked trim piece, or a faulty electrical switch, RV Designer offers purpose-built solutions designed specifically for recreational vehicles rather than adapted from residential or commercial hardware.</p><p>For keeping entrances secure and functional, their <a href="/7534-rv-designer-door-latches-200339">door latches</a> are engineered to fit a wide range of motor home and travel trailer entry and compartment doors, with easy installation and included fasteners. Inside the coach, <a href="/7534-rv-designer-cabinet-cupboard-latches-200226">cabinet and cupboard latches</a> keep pantry doors, overhead cabinets, and storage drawers securely closed while traveling — a small detail that makes a big difference on bumpy roads.</p><p>RV Designer's <a href="/7534-rv-designer-trim-201107">trim</a> products, including their well-known vinyl insert trim line, give RV owners a straightforward way to refresh the appearance of their coach's exterior and interior finishing — without the need for specialized tools or professional installation. These trim solutions are popular among both DIY enthusiasts and professional RV technicians alike.</p><p>On the electrical side, RV Designer offers a comprehensive range of electrical parts and accessories, including rocker switches, wall plate switches, LED puck lights, and DC electrical components. These products are designed to integrate seamlessly with the 12-volt systems found in most recreational vehicles, making repairs and upgrades straightforward for RV owners.</p><p>Rounding out their lineup, RV Designer's <a href="/200513-hardware-parts-accessories-rv-designer-7534">hardware parts and accessories</a> cover everything from compartment hardware and hitch pins to drawer slides and gas props — making them a one-stop resource for the nuts-and-bolts needs of virtually any RV repair or upgrade project.</p><h3>Why RV Enthusiasts Trust RV Designer</h3><p>RV Designer takes an &quot;old-fashioned customers-first&quot; approach to business, standing behind every product in their catalog. Their 12,000-square-foot facility in Wheeling, Illinois serves as the hub for a product development process that emphasizes stringent testing to ensure long-term performance. With over 500 products across interior, exterior, electrical, and trim categories, RV Designer provides the depth and reliability that RV owners depend on to keep their rigs in top condition for years of adventures ahead.</p>

Product Details

The RV Designer TC505 is a heavy-duty trailer wiring adapter that converts a 7-way RV-style connector to a 4-way flat connector, making it ideal for towing lightweight trailers, utility trailers, and small cargo trailers behind your RV or truck. This adapter allows you to connect trailers with 4-way flat wiring to vehicles equipped with 7-way RV connectors.

Key Features:

  • Converts 7-way RV blade connector to 4-way flat connector
  • Durable nylon housing withstands outdoor elements and road conditions
  • Corrosion-resistant brass terminals ensure reliable electrical connections
  • Plug-and-play design requires no cutting or splicing
  • Handles standard trailer lighting functions: running lights, brake lights, turn signals, and ground
  • Compact design for easy storage when not in use

This adapter is perfect for RV owners who occasionally tow smaller trailers equipped with 4-way flat connectors, eliminating the need for separate tow vehicles or rewiring. The corrosion-resistant terminals maintain consistent performance even in harsh weather conditions, while the rugged nylon construction provides long-lasting durability.
