Spur Grommets By the DOZEN
These are not the grommets you buy at Walmart or Home Depot. They have spurs, and the metal is substantial. The #2 Grommets are about 7/16" ID and the #4 are about 9/16" ID. They are either solid brass, or nickel plated brass.
You will need a Spur Grommet Setting Tool to set these grommets.
