Spanning 40.5 inches wide by 34.5 inches high, this walnut-finished panel carries a 40-by-29.5-inch grid and sits just 1.5 inches off the wall. A 5-inch-deep holder rail runs the full width beneath it, deep enough to hold the acrylic discs after the quick release drops them. At 28.5 pounds the metal frame calls for the supplied anchors and a solid wall, and once fixed it stays put through fast, repeated play. Mounting height is chosen at install, which lets a household set the grid for standing adults or for seated children at a table. The dark walnut face makes light and dark discs easy to read from across a room, so spectators can follow a match. Assembly covers the frame, the rail and the wall fittings.
