Full product description
The Wallace Auto-Locking Trailer Coupler Kit provides a medium-duty towing solution for A-frame trailers, centered around a precision-engineered 2" hitch ball connection.
This professional-grade coupler is rated for a 12,000lbs gross trailer weight and features an integrated quick-latch mechanism that automatically snaps into place when lowered onto the ball.
Designed for ease of use and long-term reliability, the unit is finished with a heavy-duty powder coat to resist rust and corrosion, while a simple release handle ensures an effortless disconnect even after heavy hauling.
Providing the structural backbone for this kit is a 12" tall, 6-hole vertical channel designed to be welded directly to the trailer tongue. While the coupler is rated for 12,000 lbs, this reinforced 5-position vertical channel is engineered to handle up to 20,000 lbs, offering a massive margin of structural safety and rigidity.
This over-built design allows you to bolt the coupler at various heights to ensure a perfectly level tow, providing the heavy-duty foundation needed for the towing vehicles and demanding environments. Professional welding required to install the 6 hole, 5 position vertical channel onto your trailer tongue. California Residents: Prop 65 Warning
