Adjustable aluminum deck mount brackets add a flower box to your deck easily. These brackets easily mount to a 2-inch by 4-inch or 2-inch by 6-inch deck rail, for a versatile holder. Space these braces according to the size of your flower box, allowing for 3-inch of overhang on each side, to accommodate a large range of box sizes. Simply adjust the mounting bracket to the appropriate size for your deck rail, and use the included screws to secure it in place.
