Using this toilet paper dispenser is easy. First, mount it on the wall by locking the support - arm flanges to the concealed stainless steel wall plate. Then, place a toilet paper roll with a diameter of up to 5 1/2' (140mm) on the chrome - plated plastic spindle. When it comes to maintenance, regularly wipe the satin - finished stainless steel surface with a soft, damp cloth to keep it clean and shiny. Avoid using abrasive cleaners as they may scratch the surface. Also, make sure to replace the toilet paper roll when it runs out to ensure continuous use.
