The Model 579 was designed as a versatile and economical solution for small residential and light commercial drapery track applications. Small in size and big in features, the Model 579 can operate tracks up to 20' in length and curtain weights up to 60 pounds. Track mounted limit switches provide positive end of travel signals and allow for a moderate amount of cable slippage. This machine also includes a built in timer to ensure that the machine will shut off even if the cord slips or breaks during operation. Incorporating features such as variable speed, user definable maximum and minimum speed settings and optional wireless remote control makes this one of the most versatile drapery operators on the market today.
