OZCO T4-850 OZ-Post Anchor: 3-1/2" Square Post Foundation
OZCO T4-850 OZ-Post Anchor (3-1/2" Square) is a 34" heavy-duty anchor for 4x4 posts that need extra stability—taller fences, gates, railing posts, and exposed-frame projects. The long shaft and fin design help resist side loads and uplift, so posts stay straighter over time without the hassle of concrete piers.
It’s made from hot-dip galvanized steel for long-term outdoor performance and is approved for use with ACQ-treated lumber. Drive it with an Oz-Post manual or jackhammer driver kit, attach your 4x4 post, and start building.
