This system is built with Premier Panels, our number one selling cattle panel. The Alley Frames maintain the strength and support of the 28” wide alley and the “no-back” Alley Stop can be easily adjusted to prevent cattle from backing out of the alley. The attractive and durable Architectural Grade Powder Coat Finish with UV inhibitors will add years of life to your investment by helping this system resist rust, scratches and fading.
