Using your Bobrick B - 2892 commercial toilet paper dispenser is easy. First, unlock the tumbler lock to open the dispenser. If you're using 10 - inch rolls with a 2 1/4 - inch core, place them on the spindles. If you have 3 - inch core rolls, convert the dispenser as needed. Close the sliding access panel, and you're ready to go. When it's time to change the roll, simply slide the access panel to expose the empty roll and replace it. To keep your dispenser in good shape, regularly clean the satin - finish stainless steel with a mild cleaner. Avoid using abrasive materials as they can scratch the surface. Check the tumbler lock periodically to ensure it's working properly. Also, make sure to use the correct size of toilet paper rolls to prevent jams.
