What functions does the grommet of the flag serve?

The grommet of a flag plays a crucial role in flag attachment, specifically providing a reinforced hole that allows for secure attachment to a rope or flagpole. This functionality is essential for ensuring that the flag can be hoisted and displayed properly without the risk of damage. The strong, typically metal or plastic, grommet helps maintain the integrity of the fabric around the hole, allowing the flag to withstand outdoor elements such as wind and rain.

While hoisting the flag is an important task, the grommet's primary purpose is to facilitate the connection to the rope or other support systems, which is why this function highlights its significance. Additionally, grommets are not intended for decorative purposes, and while they do help prevent fraying to some extent, their main function is directly related to the attachment of the flag.
