Using the Bobrick B - 273 toilet paper dispenser is easy. First, unlock the dispenser using the appropriate key. Then, insert a roll of toilet paper with a diameter of up to 6' (150mm) onto the plastic spindles. Close the dispenser and lock it again to prevent theft. When you need toilet paper, simply pull it out gently, and the controlled - delivery feature will make sure you get an appropriate amount. For maintenance, regularly clean the satin - finished surface with a soft, damp cloth. Avoid using abrasive cleaners as they may damage the finish. Check the locking device periodically to ensure it's working properly. If you encounter any issues, contact the manufacturer for support.
