Designed to hold flowerboxes securely to a deck rail, the 6-inch Clamp-On Flower Box Brackets can be placed on the railing according to your spacing preferences. No additional tools or hardware are required, with no permanent damage to the railing. Brackets and boxes can easily be removed for end-of-season storage or repositioning. This smallest bracket fits our Achla Designs Small Galvanized Flower Boxes, available in Green, White, Blue patina or Copper plating.
