Large rubber grommets are common in rings, inserted into or through a hole or puncture in a material typically used to prevent wear, tearing or abrasion. In this way, it can guard the material where the grommet is settled, or even to protect other materials, like wires, cables, or tubing passing through the hole.

Furthermore,Large rubber grommets also use as a dress or cosmetic improvement on a product with a puncture that contains sharp or uneven edges.
