Using this Bobrick B - 6867 toilet paper dispenser is easy. First, open the dispenser by unlocking the support arm flanges. 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 make sure the flanges are locked properly. When it comes to maintenance, wipe the satin stainless steel surface regularly with a soft cloth to keep it clean and shiny. Avoid using abrasive cleaners as they may scratch the surface. If you notice any issues with the locking mechanism or the spindle, contact the manufacturer for assistance.
