Springer Magrath Obstetrical Straps are easier on both cow and calf than chains. The 1-inch width spreads pulling tension over a wider area of the calf's legs to help prevent bone fractures and soft-tissue injury. Made of soft yet sturdy, washable nylon webbing with stainless-steel D rings. Bright teal color that is easy to find. Can be used with or without a mechanical tension device. Available in three lengths.
