In 2016 Advanced Dairy Systems absorbed Nielsen Industries, which gave ADS the foothold it needed to enter into the world of stanchions. Nielsen Industries has been manufacturing the world renowned “self-locking” stanchion since 1954. These stanchions are still the most durable on the market. You have the ability to release individual animals or lock an entire run with no harm to your fingers. With these stanchions no curb center supports are required. Available in a variety of sizes and mounting options making it easy to retrofit any dairy. Contact for More Information and Pricing.
