Using this paper towel roll is easy. Simply pull the towel from the dispenser, and the touch - free mechanism will do the rest, giving you a 12 - foot length of towel each time. When it's time to refill, unlock the cabinet using the provided keys. You can replace the roll with an 8 - inch wide and up to 8 - inch diameter roll that's 800 feet long. For the stub roll, the automatic transfer feature will handle it smoothly. To keep it in good condition, regularly clean the exterior with a mild cleaner. Avoid using abrasive materials that could scratch the satin - finish stainless steel or the plastic parts. Make sure to keep the keys in a safe place so you can access the cabinet when needed.
