Using this toilet paper dispenser is easy. First, make sure to install it following the ADA standards and local codes. Open the hinged service door at the bottom of the unit to load two rolls of up to 5-1/4 inch core toilet paper. The dispenser will automatically drop the fresh roll when the first one is used up. Remember, the retaining mechanism will prevent you from using the spare roll until the first one is completely gone. For maintenance, regularly clean the stainless - steel surfaces with a soft cloth and mild cleaner to keep the satin finish looking great. Don't try to remove the molded polyethylene spindle as it's non - removable by the user. If you need to service the lock or any other internal parts, use the tumbler key that matches other Bradley units.
