Signature Series Post Hole Plug | Black Finish

Post hole plugs cover unused holes where tensioners are not present. They are especially useful for covering holes at transitions, such as stair landings or when changing to a lower post height within a project.

Cleaning anodized components is easy.

Use a Neutral Cleaner: Use mild dish soap or detergent with a pH between 6 and 8. Avoid acidic or alkaline cleaners, as they can damage the anodized coating.

Test a Small Area First: Before full application, clean a small, inconspicuous spot to ensure the cleaner doesn't cause discoloration or damage.

Clean Thoroughly and Rinse: Use a soft sponge or non-scratch cloth to clean the surface, ensuring all areas are addressed to prevent contaminant buildup. After cleaning, rinse thoroughly with water to remove any residue.

Level III anodizing, or Type III hardcoat anodizing, is a process that creates a thick, highly wear-resistant, and corrosion-resistant oxide layer on aluminum. This is achieved through an electrochemical process that converts the aluminum surface into aluminum oxide using sulfuric acid and a controlled electrical current.

The Type III anodized aluminum finish can last over 20 years, depending on environmental conditions and wear. Coastal and high-UV environments may accelerate wear compared to inland or interior applications.
