What is "grommets"

Usage examples of "grommets".

On the other side of the console, a couple of worn grommets in the floor showed where a piece of heavy equipment had been removed from the alcove.

The tarp was made of a medium-weight canvas, the seams stitched in red, with metal grommets inserted at regular intervals.

It had been made, designed, and manufactured in Lobynia by Lobynian technicians and was perfectly good except that it had to be replaced each week since the grommets through which the flag rope passed regularly fell out every seven days.

Only the Lobynian flag showed a change, because it was now flying at half-staff, and Remo noticed that the grommets were starting to pull loose.
