A grommet can be used in furniture to protect wires, cables or cords for computer equipment or other electronic equipment in homes or offices. At the same time, they are used decoratively to embellish the furniture and can be bought in a large variety of sizes, colors and finishes.

The grommets usually consist of two pieces: A liner that goes into the hole of the furniture and a cap with a hole (often adjustable in size) for the cables to go through.

When there is no need to use them they can be blanked either by turning one piece 90° against the other or by inserting an extra plastic piece designed to fit that purpose.
