Using this toilet paper dispenser is easy. First, open the concealed locking device to access the inside. Then, place two rolls of toilet paper on the plastic spindles. Make sure the rolls are within the size limit of up to 6' (150mm) in diameter. Once the rolls are in place, close the dispenser. The controlled delivery feature ensures that you can pull out an appropriate amount of toilet paper. When it comes to maintenance, simply wipe the cast - aluminum body with a clean, dry cloth regularly to keep the satin finish looking good. Avoid using abrasive cleaners as they may damage the surface. If you notice any issues with the locking device, contact the manufacturer for assistance.
