Gate Blank Post
This post has a heavier wall then standard posts to support the weight of gates. "Blank" means it has no holes in the posts for section rails to slide into. This post is normally used as a terminating post when a gate is on the end of a line of fence. The gate blank post would be used as a latch post for the gate. It is better to plan your project to hang gate hinges from regular gate end posts, since the attached section provides additonal support to the post as opposed to hanging it on a gate blank post. That post is free-standing and is not as strong as the supported one.
