This extension set is used to extend the length of any low-series raised metal garden bed. The set includes a pair of corrugated sidewalls, adjustable cross braces, and hardware. The side panels overlap each other to form a continuous wall. The cross braces are adjustable in length to span either 22" or 40" wide beds. Connect up to 2 extension sets per bed. A maximum of 2 extension sets can be joined to form a 112" long bed, if longer runs are desired, start a new bed butted end-to-end to ensure structural integrity. Almont & Co. planters and beds make estate-quality gardens easy and affordable for all.
