The new Evolution Structural Wood Post Anchor elevates appearance and performance to new heights. Use this install kit so you can show off beautiful wood posts and get the performance that matches steel structural posts. It's the smallest, most unassuming yet strongest surface mounted wood post anchor you will find. Stand alone 42 in. 4 x 4 posts are rated to a minimum of 500 lbs. on concrete and the 6x6 anchor performs even higher.
