Using this Bobrick toilet tissue dispenser is easy. First, unlock the tumbler lock with the provided key. Then, open the dispenser and place two toilet tissue rolls on the theft - resistant spindles. Make sure the rolls are properly seated. Close the dispenser and lock it again. For maintenance, regularly check the spindles for any signs of wear. If the dispenser gets dirty, you can use a mild soap and water solution to clean the matte black finish. Avoid using abrasive cleaners as they may damage the surface. When you need to change the mounting style, you can remove the skirt in the field for recessed mounting. Always keep the key in a safe place to ensure security.
