The CURT Manufacturing TriFlex brake control is a proportional brake control that senses the inertia of the tow vehicle, allowing it to accurately apply the appropriate amount of power to the trailer brakes. The technology behind this control is the use of a triple-axis (x, y, z axes) accelerometer, located within the brake control. As the tow vehicle’s speed and momentum change, the TriFlex provides the exact amount of braking power needed for safe, efficient and smooth stops every time. The CURT TriFlex brake control easy to install, it can also be mounted at various angles and is ready to use in fewer than ten minutes. The sensitivity adjustment feature in the TriFlex allows the user to customize the brake control based on varying trailer loads or driving conditions. It is compatible with advanced multiplex electrical systems, electric-over-hydraulic braking systems and can be used on trailers with up to four axles.
