Using the ASI 0484 Toilet Seat Cover and Toilet Paper Dispenser is easy. First, find a partition with a thickness between 1/2 and 2 inches and make a rough opening that's 15 - 1/2 inches wide and 28 - 7/8 inches high. Then, mount the dispenser on the partition. You can place standard or 1800 - sheet rolls that are 4 - 1/2 inches wide and 5 - 1/4 inches in diameter inside. There are 500 standard toilet seat covers and two rolls of toilet paper available on each side of the partition. When it's time to refill, you can do it all from one side. Keep in mind that the dispenser has a tumbler lock for security, so make sure you have the key. To maintain it, simply wipe the No. 4 satin - finished surfaces regularly to keep them looking good and to prevent fingerprint build - up.
