An optional top kit for our raised-bed kit. This add-on lets you make a hinged top to cover the bed with plastic film, row cover material or netting. The kit accepts standard 1" × 2" lumber (which you supply) to make any size of top up to a recommended 4' × 4' maximum. It also locks in an upright position so it can be used as a trellis wall when covered with netting. Each top kit includes four corner brackets with two hinges. Patio stones and lumber not included.
