Deer Fence Post Sleeves
Basic post and sleeve breakdown:
The anvil slides into the ground sleeve. You then drive the sleeve into the ground by hitting the anvil with a sledge hammer. The anvil prevents the top of the sleeve from getting damaged from the hammer.
After your ground sleeve is in the ground, slide your post into the sleeve. The fit is snug and the post telescopes in the sleeve most of the way. There are holes at the bottom of each sleeve for drainage and space for water expansion. Without this space and drainage, water could freeze and burst the ground sleeve in cold climates. Posts and sleeves are both galvanized to prevent rust. Sleeves are roughly two feet long. To lock the post into the sleeve, hammer a small galvanized nail between the post and the sleeve. This will prevent the post from spinning and you won't be able to pull it out of the sleeve. Caution: the nail is not easy to get out after you drive it in, if you decide to remove the post from sleeve later
