ANTO 7-Blade to 7-Pole Round Trailer Plug Adapter — Die-Cast Zinc with Mounting Bracket, Weather-Resistant Wiring

ANTO's 7-blade to 7-pole round RV trailer plug adapter converts a 7-way blade outlet to a 7-pole round connector while providing a durable mounting bracket and protective wiring for reliable towing connections.

This compact electrical adapter from ANTO bridges two common trailer wiring standards, making it easier to connect trailers, campers, and towing accessories that use different plug types. Built from die-cast zinc and fitted with flexible wiring protected by convoluted tubing, the adapter resists impact and corrosion. A spring-loaded dust cover shields the socket when it’s not in use, and the included mounting bracket helps secure the connector to a vehicle or trailer for a cleaner, safer installation.

How does this adapter simplify trailer hookups?

The ANTO adapter lets you plug a 7-way blade-style outlet into a 7-pole round trailer plug without rewiring either vehicle or trailer. It maintains the standard pin functions so lights and brakes operate as expected, and the flexible wire offers installation options where space or alignment is limited.

• Converts 7-way blade to 7-pole round plug compatibility.
• Preserves standard wiring functions for lights and brakes.
• Flexible wires ease routing through tight mounting points.
• Plug-and-play design reduces installation time.

Will this hold up outdoors and in salty or wet conditions?

ANTO engineered the adapter with a die-cast zinc housing and corrosion-resistant finishes to withstand outdoor exposure. The flexible wiring is enclosed in protective convoluted tubing to reduce wear from chafing and moisture, and a spring-loaded dust cover keeps contaminants out of the socket when idle.

• Die-cast zinc housing for impact and corrosion resistance.
• Convoluted tubing protects wires from abrasion and moisture.
• Spring-loaded dust cover prevents dirt build-up in the socket.
• Robust connectors for reliable electrical contact over time.

How does the mounting bracket improve installation?

The included connector socket mounting bracket secures the adapter to a fixed point on the vehicle or trailer so the plug remains stable while connecting and towing. A stable mount reduces stress on the wiring and connector, lowering the chance of accidental disconnects or cable damage during use.

• Bracket enables secure, fixed mounting to vehicle or trailer frame.
• Reduces pull and strain on the connector and wiring harness.
• Simplifies alignment for quick plug-in and removal.
• Mounting improves long-term reliability of the connection.

What practical features help with everyday towing?

Beyond conversion and durability, this adapter focuses on convenience: flexible wiring helps accommodate different vehicle layouts, the dust cover protects contacts between uses, and the sturdy connector keeps electrical signals steady for trailer lights and brakes.

• Flexible lead wires provide adaptable routing choices.
• Dust cover protects contacts for consistent performance.
• Compact size avoids interference with vehicle or trailer components.
• Standard pinout avoids rewiring or guessing signal mapping.

Who is this for? If you tow trailers, campers, horse trailers, or equipment that uses a different 7-way connector style than your tow vehicle, the ANTO 7 RV Blade to 7 Pole Round Adapter is designed to make compatibility simple and dependable. It’s suitable for DIY installers, fleet operators, and occasional tow vehicle owners who want a durable, plug-and-play solution that reduces wiring work and improves the longevity of their trailer connections.
