Using the Atlas Centinel Square Knob is a breeze. First, gather all the included mounting hardware. Then, align the holes on the knob with the pre - drilled holes on your cabinet or drawer. Insert the screws through the holes in the knob and tighten them using a screwdriver. Make sure it's firmly attached. As for maintenance, simply wipe the knob with a soft, dry cloth regularly to keep it looking new. Avoid using abrasive cleaners as they can scratch the surface. If the knob gets dirty, you can use a mild soap and water solution, but be sure to dry it thoroughly afterward. Also, check the screws from time to time to ensure they're still tight, especially if you use the cabinet or drawer frequently.
