The 2-pack Boss Buck BB-1.10 Hunting Game Feeder with 4 8-Inch Feed Ports has 10-inch ports with 4-inch I.D. openings for a deer's muzzle and accommodates the largest whitetail. The custom-designed head features a 10-degree angle and a 1-inch overhang on the feed ports. Each feed port has a drain hole to disperse any water that enters the tip of the feed port. This 2-pack design features an internal cone that dispenses the feed evenly to the three feed ports. The adjustable 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.
