Here we have the breaker way pin. If in the event that the caravan becomes detached from the car, this pin is simply pulled out. This completes the circuit which activates the brakes on the caravan and locks them up, stopping the van from going down the highway uncontrolled. Once we push this pin back in again, that stops the activation of the brakes and we're free to run again. Here continue on we have what we call an off-road coupling. This coupling is designed to turn full 360 degrees all the way around both ways and this head piece is designed to do the same all the way around. Simply 50mm ball with the release mechanism up, drop it on the toe ball. The beautiful feature, the beautiful thing with this particular style of coupling is we don't have to change our toe ball to a pin or any other sort of receiver. This particular off-road coupling will go on any toe ball that's 50mm. So if we're towing a boat or a box trailer, we're not constantly changing the pin point. It remains a toe ball and all applications on our vehicle.
