Using this Bradley toilet paper dispenser is a breeze. First, unlock the tumbler lock using the key provided, which is the same as other Bradley units. Open the service door that's hinged at the bottom. Place two rolls of up to 5 - 1/4 inch core toilet tissue on the non - removable molded polyethylene spindle. Close the door and lock it. As you use the first roll, when it runs out, a fresh roll will automatically drop down for use. Remember, the special mechanism will keep the spare roll in place until the first one is completely used. For maintenance, regularly clean the stainless - steel surfaces with a mild cleaner to keep the satin finish looking great. Avoid using abrasive materials that could scratch the dispenser. Also, check the lock and hinge periodically to ensure they're working smoothly.
