The two most important features for any billiard frame are strength flatness. Since slate can weigh up to 600 lbs., the platform that it rests upon is an important component to any table. Our models feature an X-FRAME built to withstand up to 10,000 lbs. This unique, one-piece design will never separate, insures maximum stability, is movable and it's flexible, eliminating sag spread. Artisan Designs is the only manufacturer in the industry to offer this design and it's guaranteed to meet all specifications from The Professional Billiard Tour Association.
