Turn brake?

[motoassassin]

What is the turn brake used in rj Andersons video. I know you can't have one for rear tires because of closed diff. So is his connected for the front tires or is it used like a handbrake were it locks up the back tires only unlike using the pedal that brakes all 4 wheels
