This set of MDF interlocking pieces is used to convert a 6’ x 4’ table or mat into a 60” x 44” play area. The MDF is rough on one side to grip the mat or table and has interlocking pieces to keep them from moving during the game. The side boards can be engraved with a custom logo or come with our company logo. If you need a different conversion size hit up our contact page and let us know. We can make these any size.
