Using this toilet seat cover dispenser is easy. First, open the door and load up to 500 toilet seat covers inside. When someone needs a seat cover, they can simply pull one out. Make sure to install it in a wall with the correct rough opening size: 15 5/8 inches wide, 11 1/4 inches high, and 2 3/4 inches deep at least. For maintenance, wipe the satin-finish stainless steel body regularly with a soft cloth to keep it looking clean. Avoid using abrasive cleaners as they might scratch the surface. Check the dispenser periodically to ensure there are enough seat covers and that the mechanism is working smoothly.
