Using this ASI 7402 - SW toilet paper dispenser is easy. First, make sure you have a rough opening that's 5.5 inches wide, 5.5 inches high, and 2 inches deep for installation. Use the perforated lugs on the outer shell to mount it securely. When it's time to refill, simply press on the metal - spring - equipped roller. This will make it contract, and you can then place a new standard core toilet tissue roll up to 6 inches in diameter into the dispenser. As for maintenance, wipe it down regularly with a soft, damp cloth to keep the satin finish looking great. Avoid using abrasive cleaners as they might damage the stainless - steel body or the chrome - plated roller. Also, check the roller and the spring occasionally to ensure they're working properly.
