Using this Bradley 5A00 toilet paper dispenser is easy. First, open the service door at the bottom of the unit using the key. Place two rolls of up to 5 - 1/4 - inch core toilet tissue on the non - removable spindle. Close the door. When you start using the toilet paper, the first roll will be used. Once it's finished, the second roll will automatically drop down. Remember, the spare roll won't be used until the first one is completely gone. For maintenance, regularly clean the dispenser with a mild cleaner to keep the satin finish looking good. Don't use abrasive materials as they can scratch the stainless steel. When installing, make sure to follow the ADA standards and local codes. If you have any issues with the lock or the spindle, contact Bradley customer service.
