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.

Feedback:

The grommets are the thing - I am addicted to them. best damn grommets I have ever used - I'll never go back to the cheapo brass ones from the sporting goods stores.

By the way, I have discovered a handy way for making the holes for the
grommets: I have several punches for 3/8 grommets, but none for 7/16.

What I do is take a 3/8 punch and heat it up nice and hot. I hold it against the material until it burns through. It cuts the hole and sort of glues the edges together at the same time. While it is still hot, I force the grommet through (if you let it cool all the way, the edges of the hole harden up and you can't get the grommet through - just heat the punch again and repeat.) Whack that baby down and go on to the next punch point. This works on both Dacron and polytarp.

The biggest sail I have made is a 72sf Balanced Lug - that was a bit much. I might get started on my 96sf main for my Weekender today. Red and white striped. It'll look FANTASTIC.
