*We have returned to our previous shiny black O-Ring. Our black metal o-rings are welded steel rings that have been black oxidized. They come in 3/4 Inch, 1 Inch, and 1 1/2 Inch sizes, and are measured by the inside bar where your material would attach to the O-Ring. So, if you are ordering 1-inch polypropylene webbing you would want to order a 1" O-Ring. Black metal o-rings are more resistant to corrosion and have a durable color.
