Make boosting curb appeal an effortless affair with maintenance-free fiberglass. Our 36" Supreme Window Box design comes from a superior "extruded" manufacturing process, whereby fiberglass is molded into a high-strength, low-weight garden container. Fiberglass is also inherently resistant to moisture and weather, meaning the material will not rot, mold, crack or split. Display in any climate, year round if desired. Or, take advantage of the easy-to-rinse smooth surface for simple cleaning and storage.

Each Supreme Fiberglass Planter Box comes with (2) standard wall brackets and bolts, a silky black finish and a custom-fit drainage mat. This runoff system guides excess water over the convex container bottom to exit the planter through openings in the end-cap. No over-watering or root rot, and optimal airflow encourages healthy growth all season long.

Outdoor fiberglass planters online can be ordered in various standard colors and sizes. To request custom lengths measuring up to 14ft., please call toll free.

Our line of Supreme Fiberglass Window Boxes come with wall brackets to hang your window box beneath a window on your home. Bolts are included, but if you are mounting the box to a stone/brick home, you will need to purchase lag shields separately. Diagrams are shown below so that you can see how the boxes are mounted to a wall and to a railing.
