Add curb appeal to a front porch, create a container garden, or decorate with seasonal plantings on a balcony or deck. Our Medium Green Flower Box Kit for 2 x 6 Railings has two top-mounted brackets that simply and securely hold our Medium Green Patina Galvanized Flower Box planter. For easy installation, place the two wrought iron brackets at the desired width apart and secure them with the stainless steel screws provided. Fill the box with your choice of planting and place it within the brackets. Kits are also available for 2 x 6-inch railings for Medium and Large Flower Boxes, in all four Flower Box colors.
