Model 22H single door feeder is constructed of heavy 20 guage galvanized steel for years of service. It has an adjustable feed gate at trough with fast feed flow, and a 1-Inch (2-1/24 cm) wide feed saver lip. Approximate feed capacity is 80 lbs The 22H feeder can handle 4 week-old pigs to sows. Top covers raise from back for easy filling without disturbing the hogs. Heavy weathertight trough lids keep out moisture and pests. Overall size is 23-Inch wide x 20-Inch long x 36 1/2-Inch high.
BOTTOM LINE - THIS HOG FEEDER IS MADE OUT THICK GALVANIZED STEEL. NOT PAINTED STEEL THAT WILL RUST AWAY, HOG FEED USUALLY CONTAINS MINERALS THAT ARE QUITE CORROSIVE AND OF COURSE THE MANURE!
YOUR HOGS WILL HAVE A HARD TIME DESTROYING THIS ONE. IT WEIGHS 44 LBS EMPTY!
SOME ASSEMBLY IS REQUIRED - ABOUT 30 MINUTES.
WORTH THE FEW EXTRA DOLLARS, OVER COMPETITORS MODEL.
I WOULD ADD SOME SILICONE TYPE SEALANT ALONG THE SEAMS IF YOU PLAN ON LEAVING OUTDOORS.
