Our own invention - two anodized aluminum washers that fit on each side of the fabric. Special tools are not required - simply use a hammer to mushroom the ends of the soft aluminum rivets in place. Nearly as strong as a 7/8-inch ring and eyelet (easily so if a short length of webbing is placed on one side to add reinforcement.) Recommended for use on spinnakers and boats 22 feet and under.
Sold per pair Outer diameter = 1 1/2" Inner diameter = 7/8" Rivets Semi-Tubular 1/8" x 3/8" (included)
