These galvanized steel "pins" have a specially designed 1/4 kinked staff that grab the ground upon insertion and will not easily slip out. The deer fence stakes keep the poly fence securely fastened to the ground so that deer, dogs, or small animals cannot push under the fence. Our ground stakes are ideal for sandy and clay soils. For rocky soil, opt for our 12” Rocky Rebar Stakes. To determine how many stakes you need simply divide the total amount of footage of deer fence by 5. For example if you are going to fence 300 feet you need 60 ground stakes.
