The Noble Corner Feeder is made of specially formulated molded polyurethane that is FDA approved. It is a rotational molded product, meaning it has a seamless construction. The lighter earthtone color of the Noble Feeder does not show as much dirt and grime from daily use as darker colored feeders. The color also gives the feeder a brighter interior which horses seem to prefer (horses do not like to put their heads in a black hole). It is designed to bolt into the corner of a stall or paddock.
