This heavy duty 20’ alley kit is a great way to add length to your Rough Stock Open Alley. The RSOS-6 includes a “no-back” alley stop and two Rough Stock Open Preg Panels. With no tools, the “no-back” Alley Stop can be easily adjusted to prevent cattle from backing out of the alley. The Preg Panels can be used to provide secure access for palpation or AI work, and can also double as sorting gates. This system is constructed from our heaviest, most durable panels, Priefert Rough Stock Panels, to ensure that it can handle even the rankest cattle. The Architectural Grade Powder Coat Finish helps the product to resist rust, scratches, and fading to add years of life to your investment.
