The Moultrie Internal Feeder Funnel is an upgrade for Moultrie metal barrel game feeders, and compatible with many competing models. The Internal Feeder Funnel saves feed and time by directing all the wildlife feed in the hopper to the spinner, leaving no feed on the bottom of the barrel where it has to be manually scraped up, or it is lost from mold and mildew. With the Moultrie Internal Feeder Funnel all your feed is dispensed out onto the ground where it is consumed by wildlife. 55-gallon is 23"; 30-gallon is 18-1/8". Promotes efficient feeding with no waste Leaves no feed on the bottom of the barrel Saves feed and time
