With our patented protein/gravity Head you get the most moisture resistant free feeding system available. The 4-way feeder head features a 10 degree of angle and 1″ overhang on the 4″ I.D. / 8″ long feed ports. Each feed port has a drain hole to disperse any water that enters the tip of the feed port. Our patented design features an internal cone that dispenses the feed evenly to all four feed ports. The 4-way inner sleeve allows the user to control the feed flow of almost all feed shapes and sizes. Push it all the way up to virtually shut off the flow, or ease it down until you get the optimal flow on your favorite type of critter food. Our double-walled hatch lid tops this unit off in style and function. Built oversized, this lid allows the hopper system to breathe, thus eliminating condensation while achieving ambient temperature faster than steel or fiberglass feeders.
