Using this toilet paper dispenser is easy. First, unlock the support - arm flanges to open the dispenser. Then, place a toilet paper roll with a diameter of up to 5 1/2' (140mm) on the chrome - plated plastic spindle. Close the dispenser and lock the support - arm flanges back onto the wall plate. When the roll runs out, simply repeat the process. As for maintenance, regularly wipe the satin - finished stainless - steel body with a soft, dry cloth to keep it looking clean and new. Avoid using abrasive cleaners as they may damage the finish. If you notice any issues with the locking mechanism or the spindle, contact the manufacturer for assistance.
