A quality Post Base made by Simpson Strong-Tie. Used to raise timber posts and timber framework above ground level, which prevents rotting caused by moisture from ground contact. The height/level of the square support plate can easily be adjusted after installation which is useful when building structures on uneven ground. Suitable for structurally supported timber posts and framework that need to last a long time e.g. for a basic timber porch or decking framework. Not recommended for free standing posts e.g. fence posts.
