When the tow vehicle slows, the trailer pushes forward against the actuator, which pressurizes the master cylinder and applies the trailer's hydraulic brakes in proportion to how hard you're stopping. The coupler accepts a 2-inch ball and the actuator bolts onto a 3-inch-wide straight tongue.\u003c\/p\u003e\u003cp\u003eThis model does not have a reverse lockout. Mounting bolts are not included.\u003c\/p\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrailers with hydraulic drum brakes\u003c\/li\u003e\n\u003cli\u003e3-inch-wide straight tongue (bolt-on)\u003c\/li\u003e\n\u003cli\u003e2-inch hitch ball\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003eMeasure your trailer tongue and confirm your brake type before ordering.
