Can you use the brackets that come with it to attach to wood posts or is there a special bracket?

Yes, you can use the included brackets to attach the Deckorators rail kit to wood posts, but you’ll need to purchase separate self-drilling wood screws. The screws provided are designed for aluminum posts, which are softer and less dense than pressure-treated lumber, so using proper corrosion-resistant wood screws will ensure a secure and long-lasting installation.
