Using the Atlas Fulcrum Knob is easy. First, gather all the mounting hardware that comes with the knob. Then, line up the holes on the knob with the holes on your cabinet or furniture. Insert the screws through the holes and tighten them gently with a screwdriver. Make sure the knob is firmly attached but don't over - tighten as it might damage the knob or the surface. As for maintenance, just use a soft, damp cloth to wipe the knob clean. Avoid using abrasive cleaners or harsh chemicals as they can scratch the smooth finish of the zinc alloy. If you notice any loose screws over time, simply tighten them again to keep the knob secure. Enjoy the stylish and functional addition to your home!
