This sturdy, inground picnic table is round with a diamond-style design. The frame is all-welded with a 4" x 4" square center post and heavy-duty round extension arms supporting the seats. The table top and seats are coated with thermoplastic, which has ultra-violet protection, impact resistance, excellent mechanical performance and superior ultra-high adhesion. Table tops and seats are available in a variety of colors, as is the powder-coated frame. Choose from three mounting options: inground mount, surface mount or portable. The surface mount is a large, 4-hole plate that is welded to the center post. All tables come with an umbrella hole - see item #627008 for umbrella options.
