Double L's STF1415 HDPE Sow Feeder eliminates expensive repair costs for stainless steel feeders and reduces feed waste thanks to its rounded corners / bottom. Double L's Sow Feeder is very hygienic since there is no front lip on feeder - reducing feed buildup and bacteria. Constructed of strong high density polyethylene, the Double L Sow Feeder is reinforced at feeder rod locations to reduce wear. Since it is made of polyethylene, the Double L Sow Feeder is much quieter than steel and is lightweight.
