Simplify container gardening with a durable 24" Supreme Fiberglass Window Box in black. This classic design is constructed using an extruded manufacturing process to yield strong containers that are also lightweight. Fiberglass flower boxes have a complete, smooth finish and planters can be rinsed inside and out. The material will never rot or mold and is resistant to heat and cold, making this a true all-weather planter.

Each Supreme Fiberglass Flower Box comes with (2) wall brackets and bolts and a custom drainage mat. By channeling water toward holes in the end-cap, this drainage system eliminates the need for additional cover like pebbles. Also discourages over-watering while encouraging healthy circulation of air and heat to plant roots.

This product can be manufactured in custom lengths up to 14ft. - call toll free for details and pricing. Please note that additional hardware may be required for different mounting surfaces.
