OverviewThe Miller OB Calf Strap is a 52" combination chain-and-nylon calving strap designed for use during assisted deliveries in cattle. When a calf requires manual or mechanical traction to assist delivery, OB straps are looped above the fetlock joints of the calf's legs to provide a secure attachment point for pulling — either by hand or in conjunction with a calf puller. The combination of a durable metal chain and nylon strap provides both strength and flexibility, allowing the strap to conform to the calf's leg while maintaining a secure grip.
