Kerckhaert has made another major step towards healthier hooves with the design and development of the Liberty Cu horseshoe nail. The Cu nails are copper coated, offering more protection than traditional horseshoe nails. These innovative nails are designed to eliminate microorganisms that enter the hoof wall through the nail holes, helping prevent infection from developing. The copper surface kills bacteria as soon as it comes in contact with the nails and helps hooves remain strong and healthy throughout the shoeing cycle. 250 Pieces per box.
