This maintenance FREE hopper system , with 72" feeder legs is the BEST SELLER in our line. With our Patented Protein/Gravity Head you get the most moisture resistant free choice feeding system available on the market today ! The Custom Designed head features a 10 degree of angle, and a 1" overhang on the 4" 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 the three ports. The adjustable height 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, domed , hinged LID tops this unit off in style, and function. Built oversized, this lid allows the hopper system to breath, thus eliminating condensation. The wagon wheel bracing in the top of all Boss Buck Feeders allow this unique design to maintain it's shape while achieving ambient temperature faster than Steel or Fiberglass feeders. Perfect for feed pen set-ups that are not accessible by livestock or wild hogs. Fills easily from the ground. No ladder needed! Approximately holds:
