Using this Bradley toilet paper dispenser is easy. First, open the door using the key for the tumbler lock. Place two standard core rolls of toilet paper up to 5 inches in diameter inside the dispenser. Close the door and lock it. When the first roll is used up, the second roll will automatically drop down for continuous use. As for maintenance, simply wipe the dispenser with a soft, damp cloth regularly to keep the satin stainless - steel finish looking great. Make sure to keep the lock mechanism clean and lubricated to ensure smooth operation. Always use the key provided to open and close the door to avoid damage. Also, check the dispenser periodically to ensure that the rolls are feeding properly.
