Description
The 3 Pcs nylon OB calf pulling straps set is a low-trauma alternative to traditional obstetrical chains, designed for safer, more comfortable assisted deliveries in cattle . The SAG Surgical nylon OB strap set includes three essential lengths (30″, 45″, and 60″) with a hook handle, engineered to provide secure, gentle traction while significantly reducing the risk of injury to both the calf and cow during calving.
These  nylon OB calf pulling straps are uniquely crafted from durable, washable 1-inch wide nylon webbing that spreads pulling tension over a wider area of the calf’s legs, helping to prevent bone fractures and soft-tissue injury . The soft nylon material is easy on the calf’s limbs, making it gentler than chains . The 1-inch width is designed to spread pulling tension over a wider area of the calf’s legs to prevent injury .
This nylon OB strap set includes three versatile lengths: the 30-inch strap for smaller calves and precision work, the 45-inch strap for medium-sized breeds, and the 60-inch strap which features a floating third D-ring design to ensure the OB handle pulls equally, staying in the center of the strap . The heavy-duty, nickel-plated welded steel D-rings on each strap provide secure attachment to OB handles . The included hook handle completes the set, allowing for controlled, comfortable traction.
Nylon OB straps are used across various veterinary settings including cattle operations, dairy farms, and large animal veterinary practices. These calving straps assist veterinarians and livestock producers in managing difficult births with greater safety. They are also preferred by cattlemen who do not care to use chains and are an economical alternative to OB chains . The bright orange color  makes them easy to find in the calving pen.
Veterinary obstetrics instruments are manufactured to the highest standards using quality materials. This ensures that every nylon OB strap maintains its strength and reliability for years to come. These  nylon OB calf pulling straps are designed for easy cleaning and disinfection, maintaining high hygiene standards .
SAG Surgical takes pride in offering premium  nylon OB calf pulling straps that meet the demanding requirements of modern veterinary practice. Every calving strap undergoes rigorous quality control to ensure consistent performance and safety.
