DUO Stay-N-Play is the number one choice for gas powered rigs.
The Stay-IN-Play DUO supplemental-braking system is installed so there is no set up required for towing your vehicle. To get ready to tow you simply turn it on; that’s all. Turn it on... and tow. The DUO energizes the towed vehicles power brakes so it is gentle and consistent. It’s easy to see why Stay-IN-Play DUO is the number one choice.
Hidden installation under the hood of the tow car is just one of the many benefits.
Patent-pending air cylinder applies your towed vehicle’s power-assisted brakes AND automatically applies proportionate and progressive brake effort.
"Panic Stop Braking" - only SMI brings you additional stopping effort in a panic... up to three times the normal effort.
The Stay-IN-Play DUO creates vacuum to provide totally reliable and consistent brake application.
Two signals are required to activate the Stay-IN-Play DUO system. The coach brake must be applied, AND there must be sufficient G-force. No unwanted or unnecessary brake activations on grades or over bumps. And best of all, it is all automatic.
NO set up for towing - the Stay-IN-Play DUO is always ready to tow.
Simple installation mounts the small operating unit under the hood of the towed vehicle so you never know it is even installed.
On/off operation means you are tow ready in less time.
The best signal for you to know when the brakes are on in the towed vehicle is from the brake light switch. Air Force One includes a simple LED light that turns on when the brakes are applied in the tow car.
