Product Description

The Cashmans 5-inch cylinder post is a step up in diameter for paddock corners, gate posts, and fence runs that take more load than a standard line post can handle. This pressure treated fence post is made from Southern Yellow Pine and treated to a .40 retention for reliable performance in direct ground contact. Each 5-inch round post has the same diameter from end to end, making rail and board heights consistent down the full length of your fence line. The smooth, straight stock of this cylinder post installs fast and stays plumb through freeze-thaw cycles and wet seasons.

At 8 feet long, this 5-inch cylinder post gives you extra length for taller fence sections or deeper setting in soft or sandy ground. These Southern Yellow Pine posts are available individually or in bundles of 32, with a 50-cent savings per pressure treated post on bundle orders. The tight grain of Southern Yellow Pine holds nails, screws, and wire staples without splitting even under heavy lateral pressure. Stop by Cashmans in Delaware, Ohio to pick up your 5-inch cylinder posts.
