The 4×16 Rectangle Raised Bed kit is a great addition to spruce up any landscape setting. As our longest rectangle raised bed shape, this gives gardeners a large amount of space to add the plants they love. This kit is different from the smaller rectangle sizes as it also includes an extension bracket that connects two pieces of wood to make it longer. This raised bed is similar to the 4×12 but instead of adding a 4ft board to an 8ft we add an 8ft, getting the 16ft length. Below are a list of heights that we offer for this kit. Please select a height to view the product and more information.
