Made of soft and sturdy washable nylon, these Springer Magrath obstetrical straps are easier than chains on both cow and calf. The 1" width spreads pull tension over a wider area of the calf's legs, helping to prevent bone fractures and soft-tissue injury. The bright teal color makes it easy to see. | Springer Magrath Nylon and Chain OB Calf Strap | Size 52"
