These 12 inch Kinked Galvanized Aluminum Deer Fence Stakes are used to secure the bottom of our deer fencing to the ground to prevent deer from crawling under the fence. We recommend the stakes be placed approximately every 5 feet along the bottom of your deer fence. These stakes work well for most ground types; however, for rocky soils and unusually hard terrain we recommend and offer 12 or 18 inch rebar stakes. We also offer these stakes in a 250 pack for those of you with larger fencing jobs.
