Priefert’s Universal Alley Stop is the perfect solution to help prevent cattle from backing out of an alley. With no tools required, the effective height of the “no-back” Alley Stop can be quickly set to prevent the backing of bulls, cows, and calves. Designed for use with any Priefert Sweep System, two chain connectors on the frame secure the ASU to the alley panels. This product features an Architectural Grade Powder Coat finish to help it resist rust and scratching, while UV inhibitors in the powder help the ASU resist fading, ensuring that your product holds up well and looks great for many years to come.
