Why are the stabilizer chains in the middle of the extension?
The chains are at the end of the extension, just behind the receiver pin. Between the stabilized extension and the ball is the Ready Brake I spoke of. The Ready Brake moves and can not be stabilized without defeating it's operational ability.
Here is an animation of what it does;
The Ready Brake is a supplemental tow brake used when dinghy or flat towing a vehicle so your towed vehicle can assist with stopping which is a requirement in most States and Provinces. The Ready Brake will connect to any brand tow bar with a 2 inch receiver or ball hitch connection. Ready Brake uses the towed vehicle weight and it's momentum that pushes against the tow vehicle while braking to pull the towed vehicle brake pedal down. The harder you brake, the harder Ready Brake pulls the pedal for proportional braking. A shock and spring inside the Ready Brake will keep the brake from being applied while traveling down steep grades. No electronics or electricity are required to use the Ready Brake and after the initial install all that is required to connect or disconnect is a single cable that hangs over the tow bar.
