A fence post is used to secure the fencing you are installing on or around your property. You will be required to place the fence post sections apart in accordance to the type of fence you are installing.
You can find fence post supplies at any home improvement store or lumber yard and many are already treated for outdoor use.
Installing a Fence Post
You will need to dig a hole deep enough to seat the fence post down into the ground securely. Some instructions require that you pour cement into the hole to ensure the fence post is completely secure. When you buy your fencing, you are given a layout of how far to place the fence post apart from each other as well as what should be done to secure them in the ground.
Make sure that when you purchase your fence post that you have enough to do the area that will be fenced.
