Upgrade to maintenance-free outdoor planters with the Supreme Fiberglass Planter Boxes. Measuring 30in.L, this durable, all-weather container is constructed through a process of extrusion that yields strong, yet lightweight, containers. A smooth, moisture resistant finish inside and out allows for easy rinsing and also means containers will never mold or rot. Add to that a custom-fit drainage mat that funnels runoff to openings in the end cap, and you have a fool-proof system for healthy, lasting container gardens.

This product includes a pair of wall mount brackets with bolts. Additional hardware may be required per the mounting surface and any need for additional reinforcement. To request this product in a custom length, please call toll free. Supreme Fiberglass Planters can be manufactured in lengths up to 14-feet.

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. To explore additional mounting hardware, including brackets for hanging the box from a railing, visit our Optional Brackets (For Fiberglass Supreme Boxes Only) page.
