Compatible with the following Katrin hand towels: 04-009 , 04-010 , 04-011 , this Katrin System Hand Towel Dispenser is designed to reduce paper consumption across washrooms. Refilling the dispenser couldn't be easier - simply open the cover, insert a roll into the dispenser then let the paper drop freely, pulling it until it reaches the marked line before closing the cover. Used rolls automatically drop into the stub roll position when the roll reaches a certain level. Once empty, the cores can simply be pulled out side wards from the back of the dispenser and recycled.
