The 9/16" Stainless Steel hog rings are used to secure your garden fence to our monofilament wire. The Hog Ring can be used as attachment tool to our small animal control fencing - along to the bottom. We recommend using a hog ring every 12" on your deer fencing. Stainless Steel Hog rings are designed to last longer than any other hog ring out in the field. The Hog Ringer Tool we offer is required to crimp the hog rings in place. These 9/16" steel hog rings are available in packs of 2500.
