Using the Bobrick B - 686 toilet paper dispenser is easy. First, unlock the support - arm flanges and open the dispenser. Place two toilet paper rolls on the chrome - plated plastic spindle. Make sure the rolls are up to 5 1/2' (140mm) in diameter and have about 1800 sheets. Then, close the dispenser and lock the support - arm flanges back to the concealed stainless steel wall plate. When it comes to maintenance, regularly wipe the bright - polished stainless steel surface with a soft, dry cloth to keep it looking shiny. Avoid using abrasive cleaners as they may scratch the surface. Also, check the spindle and flanges periodically to ensure they are in good working condition.
