Recessed Electronic Hardwound Roll Towel Dispenser is a touchless, electronic dispensing unit to install in existing, recessed towel dispensers often found in commercial buildings. Easy-to-install dispenser adds enhanced towel capacity to reduce maintenance and refill time. It is compatible with LoCor Hardwound Roll Towels (not included) that use rapidly renewable fiber (RRF) made from eucalyptus and acacia trees that can be harvested every 6 to 8 years - less than half as long as traditional-grown trees. Attach a filler panel (not included) for a finished look. AC adapter is not included.
