The Boss Buck All-In Gravity Feeder has thick wall HDPE UV protected plastic that will not rot, rust or leak! This versatile gravity feeder is roto-molded, which is the same process used to make whitewater kayaks. The custom-designed gravity head features a 10 degree of angle, and a 1 overhang on the 4 feed ports. Each feed port is 8 long and 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 the four 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 all-in gravity feeder 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.
