what are grommets on a banner

Grommets are small metal rings that reinforce the holes drilled in a material, such as a banner, and are made for hanging the banner and protecting it. They are essential for good-looking banners, as they keep holes in the material from ripping. Grommets are punched through the banner material using a precision grommet machine to create an installation hole, and each grommet holds the vinyl securely and helps prevent the holes from spreading or tearing the banner edges off. Grommets are often used in vinyl banners, and sometimes even in yard signs and other signage. They are tiny metal rings that sometimes get confused with eyelets, but they have a specific purpose, which is reinforcement for holes. Grommets are available in various types, including metal, plastic, and rubber, and the most widely used banner grommets are metal, of varying types.
