Description These square post caps will cover any remaining open ends of your stainless steel posts. Take note how many open ends are for intermediate or terminal posts, and order accordingly. Note: Stainless Steel is highly resistant, but not impervious to the elements, and requires minimal maintenance for ideal results. We recommend applying Passivator to all exposed stainless steel components at the time of installation. In addition, apply Rust Rescue if within 10 miles of a marine environment to further protect the stainless steel.
