What is a 7 Round Trailer Plug?

A 7 round trailer plug, also known as a 7-way or RV blade connector, is a standardized electrical connector used for connecting a trailer to a towing vehicle. It consists of seven pins, each with specific functions, such as brake lights, turn signals, reverse lights, and more. This type of plug is commonly used for heavy-duty trailers, including horse trailers, camper trailers, and utility trailers.

Factors to Consider

Before making a purchase decision on a 7 round trailer plug, there are several factors that you should keep in mind.

1. Compatibility

The first thing to consider when buying a 7 round trailer plug is its compatibility with your towing vehicle and trailer. Check if your vehicle’s wiring system matches the pins on the plug. It is also crucial to ensure that the plug can handle the required voltage and amperage for your specific setup.

2. Quality

The quality of the materials used in making the plug is another critical factor to consider. Look for plugs made from durable materials such as copper or brass to ensure longevity and efficient performance.

3. Weather Resistance

If you frequently travel in different weather conditions or leave your trailer exposed outdoors, it is essential to choose a plug that is weather-resistant. Look for plugs with rubber seals or covers to protect against moisture and corrosion.
