Using the 1 3/8 Inch Atlas Ergo Knob is a breeze. First, take out the mounting hardware that comes with the knob. Align the holes on the knob with the holes on your cabinet. Then, simply attach the knob using the provided hardware and tighten it up. When it comes to maintenance, you can use a soft, damp cloth to wipe the knob clean. Avoid using abrasive cleaners as they might scratch the surface. Also, make sure to check the tightness of the knob regularly. If it starts to feel loose, just use a screwdriver to tighten the mounting hardware again. With proper care, this knob will keep looking great and functioning well for a long time.
