This kit includes a 16" diameter riser, a secure cover, and all necessary hardware for installation. Each component is made from heavy-duty, UV-resistant polyethylene, built to withstand outdoor exposure, moisture, and soil contact without corroding. The fitted cover provides a secure seal to help prevent water intrusion and limit unauthorized access.
