Durable stainless steel automatic drinker - Material and construction: made of high quality stainless steel for rust resistance and deformation resistance. Two models are shipped at random: with a drain hole or without a drainage hole. - Automatic design: a float valve automatically fills the drinking trough, so you do not need to constantly refill the bowl and livestock always have access to fresh water. - Easy mounting and safety: two holes on the back for wall mounting (mounting screws not included); polished, curved edges for safe handling and easy cleaning. - Size and capacity: 27 x 25.5 x 10 cm (10.6 inches L x 10 inches W x 3.9 inches H); large capacity to reduce refill frequency. Use scenarios - Cattle, sheep, and goat pens: mount on a barn wall or stall to provide a steady water source, reducing labor and ensuring livestock stay hydrated. - Farm sheds or outdoor pens: suitable for permanent or semi permanent installations where frequent refills are impractical, thanks to automatic filling. - Temporary or portable farm setups: easy to attach in relocated or seasonal livestock housing, with a durable design that withstands daily use.
