Using this toilet paper dispenser is easy. Just load four standard core rolls into the dispenser. When the first roll in each stall is used up, the second roll will drop down automatically for you to use. Make sure the partitions you're mounting it on are between 0.5 and 2 inches thick. To keep it secure, use the tumbler lock on the door. For maintenance, simply wipe the stainless - steel surface with a soft cloth regularly to keep it looking good and functioning well. Avoid using abrasive cleaners as they can damage the satin finish.
