A simple, elegant way to add vibrant color and greenery to a Brock Dock or any pier with 3½" OD posts. Dock Potz slip directly over the post sleeve and rest on the H-bracket supporting crossbeam, feature built-in drainage holes, and are molded from durable white high-density polypropylene — an easy, user-friendly upgrade that transforms your pier into a gorgeous focal point.

Slip-Over Fit for Brock Docks & 3½" OD Posts

Dock Potz are sized to slip directly over the sleeve of a Brock Dock post or any 3½" outside-diameter dock post, then rest securely on the H-bracket or supporting crossbeam of your dock. No tools, no brackets, and no fabrication required — just drop them on and fill them with your favorite flowers or greenery for an instant pier upgrade that adds color and elegance to your waterfront.

Durable Construction with Built-In Drainage

Molded from durable white high-density polypropylene plastic, Dock Potz are built to withstand harsh marine environments, UV exposure, and the daily cycle of watering and weather. Built-in drainage holes keep root systems healthy by preventing standing water, and the clean white finish pairs beautifully with any planting arrangement while complementing a wide range of dock styles and colors.
