Keystone Group LLC uses motors designed for quiet, consistent performance. These motors include internal dampening to reduce vibrations and ensure silent operation, making them perfect for bedrooms, nurseries, or home offices. Each unit is tested for startup smoothness, balanced tension, and speed control. Even under daily use, these motors resist jerky movement or alignment issues. Depending on setup needs, systems can be battery-powered, hardwired, or solar-assisted. Our installations hide cords and hardware for a clean finish while maintaining silent function that never disrupts your routine.
