Knobs are hardware devices which attach to cabinets, drawers, doors, appliances, and other similar mechanisms and which protrude from the surface to make it easy for a person to grasp and open, close or move that object. When selecting the best knob supplier for your needs, you might make your decision based on the knob’s purpose or you can select based on the material from which the knob is manufactured. Knobs can serve many functions beyond the simple decorative, and come in a wide range of materials from aluminum to porcelain and metal to plastic.
