Product details:

Units have ports with 4-inch I.D. openings for a deer's muzzle. Accommodates the largest whitetail. 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° angle, and a 1-inch overhang on the feed ports. The 10° pitch design requires a buck to tilt his head back when feeding. Thus eliminating any contact with the feeder hopper or feeder legs, preventing velvet antlers from being damaged. 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 feed 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.
