A grommet is a reinforced eyelet or ring, typically made of metal, rubber, or plastic, inserted into a hole in a material, often fabric, leather, or sheet metal.
Its primary function is to protect the material from abrasion or wear caused by the passage of a rope, wire, or other object through the hole, or to prevent the hole from tearing.
Grommets are commonly used in a wide range of applications, from clothing and footwear to industrial equipment and outdoor gear.
They provide a durable, finished edge to the hole while facilitating smooth movement of the inserted element.
