Stay-IN-Play DUO In Action

Watch the Demco Stay-IN-Play DUO braking system in action and learn how the system operates with this informational video!
--------------------------
An ideal supplemental braking system for every car and motorhome with a hydraulic braking system, the Stay-IN-Play DUO uses Demco’s patented technology to create a dual-signal system (brake lights and inertia) for progressive brake activation. This results in faster, more precise signals between the motorhome and towed vehicle for additional safety, longevity and easy handling. DUO combines the power of air pressure and the gentleness of vacuum to give you the fastest most powerful self contained supplemental brake ever. Duo uses the power and speed of air pressure to activate your towed vehicle brake pedal while creating vacuum for the power brake system. These two features combine to create the only progressive and proportionate vacuum assisted system with total control. Duo requires BOTH deceleration AND coach brake lights to apply the towed vehicle brakes. By combining two separate signals the need for complicated electronics is eliminated, which provides you a more reliable long lasting system. In addition, DUO is the pioneer in user friendly operation. Tried and true, DUO does not have to be taken in and out for normal operation of the towed vehicle. Unhook the car and drive off, that's all. No box, no wires, in fact, no physical connection to the motorhome at all.
-----------------------
The Stay-IN-Play DUO's patent-pending air cylinder applies your towed vehicle’s power-assisted brakes AND automatically applies proportionate and progressive brake effort. Only 10 pounds of force on your brake pedal in normal braking. "Panic Stop Braking" - only Demco brings you additional stopping effort in a panic... up to three times the normal effort. Coach notification of brakes applied with every unit. The coach brake must be applied, AND there must be sufficient G-force. Stay-In-Play Duo should not activate while the coach or towed vehicle is not moving. No unwanted or unnecessary brake activations on grades or over bumps. And best of all, it is all automatic. The air cylinder is so small it fits in the palm of your hand. No other system offers this much control and this much power all combined with a simple install. On/off operation means you are tow ready in less time.
