The flat top is what sets this arch apart from a rounded arbor. An extended flat roof spans the full width overhead, giving a level surface that is suitable for decorating with light strings, tulles, or balloons, none of which drape well over a curved crown. Below it, side climbing trellises run down both uprights and support the healthy growth of roses, ivies, and morning glories as they work their way up.Structure is handled in wood rather than thin tube. The frame is crafted from non-deformable and sturdy fir wood, a timber that holds its shape outdoors instead of twisting as it dries and takes on moisture. Solid metal connectors join the members for a firm connection at every joint, and a sturdy triangle structure combined with thick top beams promises a reliable frame that stays square under the weight of mature vines or hanging decoration.The opening is sized for people, not only plants. The entry measures 52 by 82 inches, wide and tall enough that adults pass through easily without ducking or turning sideways, which is what allows the piece to work as a garden trellis, a wedding arch, or a yard entry rather than being purely ornamental.Overall the arch measures 63 by 24 by 85 inches and weighs 25.5 pounds in dark brown. Assembly is required, and a user's manual is included.
