The 9/16" Stainless Steel hog rings are used to secure your garden fence to our monofilament wire. 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 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.
