Using this toilet paper dispenser is easy. First, make sure you have the right rough opening in the wall as specified (5 - 1/2 inches wide, 5 - 1/2 inches high, and 2 inches deep). Install the dispenser using the two perforated lugs on the outer shell. When it's time to replace the toilet paper roll, just press on the metal spring on the roller. This will make the roller contract, allowing you to take out the used roll and put in a new standard core roll up to 6 inches in diameter. As for maintenance, wipe the stainless - steel body with a soft, dry cloth regularly to keep its satin finish looking great. Avoid using abrasive cleaners as they may scratch the surface. If the roller seems stiff, check the metal spring for any damage or debris.
