Using this toilet paper dispenser is easy. Just unlock it with the provided key, open the door, and place two standard - core toilet tissue rolls inside. When the paper runs out, simply repeat the process. To keep it in good condition, clean it regularly with a mild soap and a soft cloth. Avoid using abrasive cleaners as they can damage the satin - finish stainless steel. Make sure the key is kept in a safe place as it is the same key used for other Bobrick washroom accessories. If you choose to do recessed mounting, remove the skirt before installation.
