The hardest part of building raised beds is constructing corners that are square, strong and trim. Our ingenious new Pivoting Connectors make it easy to create raised beds that will follow every twist and turn between 90 and 180 degrees. Designed and manufactured by us, here in Vermont, they're made from rust-proof, industrial-strength aluminum, coated with a life-extending powder-coated finish. Just slide your lumber into place and secure it on the inside with the screws provided.
