Shhh. With the WhisperTrac™ motorized drapery system, your light to heavily weighted drapery never has to travel louder than a whisper. The WhisperTrac™ comes in three different motor models: DT20, DT30 and DT32. The 24 volt motors can carry a maximum of 220lbs. of weight and 58 feet of drapery. The motor systems can be integrated with lighting and A/V control systems, and installed without the help of an electrician. Most drapery travels 5.9″ per second. Let Mechoshade keep those motorized seconds hushed.
