"These are 1inch 3/4 inch or 1/2 inch Beastee Dee D-rings. They are strong and can take the tip of a hiking pole to put your tarp in porch mode. They weigh just .43 grams each."
The above wording is straight from Dutch, and his team.
1" = 3.7grams
3/4" = 1.6 grams
1/2" = 0.5 grams
Exceptional as a finishing touch for your homemade gear like tarps and tents. Sold as sixes.
