Description Attach a flat toprail to square stainless steel posts through stair sections using these adjustable post caps. Make sure to order the right number of intermediate and terminal caps for intermediate and terminal posts in the angled areas of your run. 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.
