Our heavy duty deluxe line posts, made of galvanized steel and and a weather-resistant vinyl coating, are built to stand up to both the elements and your persistent deer. Their black color and round shape are designed to blend in for a sleek and professional look when installed with our poly deer fencing. We have included our galvanized steel ground sleeves to help you anchor your line posts into the ground for a long-lasting installation, and our matching cap inserts to seal your posts and protect them from collecting debris. To complete your line post installation, you will need a drive cap (not included) for every 21 posts. Place 1 heavy duty deluxe line post every 15 to 20 feet.
