Using this Bradley dispenser is easy. First, make sure it's properly recess-mounted in the desired location. To load the toilet seat covers, open the hinged access door on the side. Place up to 1000 single-fold or half-fold seat covers inside. For the toilet tissue, insert two rolls of up to 5-1/4-inch core tissue. The non-removable polyethylene spindle will hold the rolls in place. When it comes to servicing, just open the door to refill the supplies. As for maintenance, regularly wipe down the stainless steel surfaces with a mild cleaner to keep the satin finish looking great. Avoid using abrasive materials that could scratch the surface. Also, check the locks periodically to ensure they're working properly.
