Using this toilet paper dispenser is easy. First, open the service door at the bottom by using the key like other Bradley units. Place two rolls of toilet paper with up to a 5 - 1/4 - inch core on the non - removable spindle. Close the door. When you start using the toilet paper, use the paper from the first roll. Once it's all used up, a fresh roll will automatically drop down for you to use. Remember not to try to remove the spindle yourself as it's non - removable. For maintenance, regularly check the lock to make sure it works properly. Clean the dispenser with a soft cloth and mild cleaner to keep its satin finish looking good. Avoid using abrasive materials that could scratch the stainless steel surface.
