The hardest part of building a raised bed is constructing corners that are square, strong and trim-looking. Our ingenious corner brackets cut building time and result in a handsome, sturdy raised bed every time. Can be used with standard lumber or Composite Lumber, sold separately. For beds that are over 4 ft. long, add In-Line Connectors to prevent bowing. Add 12" Raised Bed Stakes to create double-height beds.
