Description from Cedarbrook Sauna and Steam
Our raised garden beds are secured by an aluminum rod thru the corners assembles in minutes!
Change your garden in a day! The ends of the garden bed boards are notched so they interlock together for superior strength. They are also pre-drilled through the tops to receive a 3/8″ solid aluminum rod which holds all the corners and joints together. The kits assemble in minutes, yet the durable all natural western red cedar can last for decades.
Height is 11″ (if ordering one unit), and may be stacked to 33″. Let us know if you are stacking them, so we may provide you with the appropriate rod length.
