What is the CURT 51110 Venturer Electric Trailer Brake Controller?

The CURT 51110 Venturer is a time-delayed brake controller designed to provide smooth and adjustable braking power for trailers with one to three axles. Unlike proportional controllers, it activates the trailer brakes based on a preset time delay after the tow vehicle’s brakes are applied, rather than the intensity of braking. This makes it a budget-friendly option for casual and light-duty towing.
