The Tarter Sliding Alley Gate helps separate animals inside of the alley for efficient handling and increased safety. It's constructed of heavy-duty square tubing and has a sheeted door to block animal view. The top-mounted, ball-bearing rollers of this optional sliding livestock door feature a self-cleaning bottom, allowing for easy, reliable movement. It can be used as an alleyway entry gate or mid-alley for scales and other uses. Made in the USA.
