Johannes Eksteen of Piketberg in South Africa says this neck clamp, which catches a cow or a bull’s head and and holds it still, has saved him many injuries and hours of time. It consists of a 50 mm pipe, flatbar of about 80 mm x 6 mm and round bar of about 12 mm which he welded together. The clamp, which is bolted onto an existing head clamp, is especially handy when you need to administer medication orally, treat the animal’s eyes, or if you need to attach an ear tag.
