if you dont want to mount a auto feeder on it, you can cut out a small rectangle, say 4 inches by 6 inches,at the bottom of the barrel and cover that with rabbit wire. then take self starting screws and large washers to secure the wire to the barrel. deer will have to paw the wire to get the corn to drop. it works really well i have used this step up for years. but i did change to auto feeders this year because of the price of corn. good luck
