The unit has 5" ports with 4" 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 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 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. Warning: Remove protein head when not in use / empty. Residue from corn/feed causes squirrels to chew on the unit when it's empty.
Boss Buck Gravity Heads are used to retro fit other manufacturers feeders by our customers. Generally a 4" pvc coupler is used or a heat gun. If the fit is loose the heating method is optimal. If the diameter is even then a coupler is the way to go.
