Using this ASI 0484 dispenser is easy. First, make sure the partition where you're going to mount it is between 1/2 and 2 inches thick. Cut a rough opening that's 15 - 1/2 inches wide and 28 - 7/8 inches high. Then, install the dispenser on the partition. You can load 500 standard toilet seat covers and two rolls of toilet tissue on each side. When refilling, open the tumbler lock. Only use rolls that are 4 - 1/2 inches wide and 5 - 1/4 inches in diameter, either standard or 1800 - sheet sizes. For maintenance, wipe the dispenser regularly with a soft cloth to keep its No. 4 satin finish looking good and to prevent fingerprints. If there are any issues, service it from one side for quick fixes.
