Grow your curb appeal with the ease of Supreme Fiberglass Window Boxes. Constructed using an extruded manufacturing technique, each outdoor garden container features inherent resistance to rot, mold, hot and cold. Each lightweight 48"L window planter also comes with three stainless steel mounting brackets, bolts and a pre-fit drainage mat to encourage healthy roots. By channeling excess water over the convex bottom of the container to escape through holes in the end-cap, container garden arrangements enjoy optimal drainage and airflow for healthy plants free of root rot.

Fiberglass planter boxes are easy to display because of their maintenance-free design. And although not required, containers are easy to rinse - water just rolls off the smooth black finish. Other colors and sizes are available online, or call toll free to ask about custom fiberglass window boxes measuring up to 14" long.
