Square & Round Wrought Iron Railings

Metal balcony railings are the perfect place to start a garden. When shopping for window box brackets for railings, be sure to take down the exact dimensions of your rail and note any considerations for vertical balusters, decorative embellishments, or architectural elements that might interfere. This will help you narrow down your selection quickly.

Determining How Many Brackets You Will Need

The longer the flower box, the heavier it gets. For containers up to 48", 1 pair will work. Boxes up to 72" require the use of 2 pairs, with additional bracket placement needed every additional 16" beyond.
