The Self Support Side Tray from MATRIX is designed to mount on a single seatbox leg without any other support. Unique oversized leg block provides an extremely secure attachment point. The side tray sits closer and minimizes the gap between seat box and tray. New outer extrusion mold provides extra rigidity. Available in two sizes: L (57cm x 45cm), XL (57cm x 57cm). Suitable for 25mm, 30mm and 36mm round legs (please note these trays are not compatible with F25 or P25 seat boxes).
