Using this toilet paper dispenser is easy. First, open the dispenser using the key for the tumbler lock. Then, place your large toilet paper rolls, up to 6' (150mm) in diameter, onto the high - impact plastic spindles. Close the dispenser and lock it back up. When you need toilet paper, simply pull it out as normal since there's no controlled delivery. As for maintenance, wipe the satin - finished heavy - duty cast aluminum surface regularly with a soft cloth to keep it looking good. Check the tumbler lock from time to time to make sure it's working properly. If the plastic spindles show any signs of wear, you might want to replace them. Keep in mind that this dispenser is designed to be vandal - resistant, but try to avoid any rough handling to make it last longer.
