This 12 foot 'J2' series rectangular picnic table seats 12 people with a heavy-duty frame made of galvanized 2 3/8 inch O.D. schedule 40 pipes. The top and seats are MCA pressure-treated southern yellow pine. MCA treatment is an effective copper-based pressure treatment that provides durable protection from decay and termites. The Center cleat holds top level and the 1 15/16 inch O.D. cross braces stabilize this extra heavy frame. The convenient walk-thru design and welded rigidity can stand up to rough use. Wooden park tables are great for group gatherings by the BBQ.
