The cross-section of a Domino dowel corresponds to that of three round dowels of the same drilling diameter, making it extremely stable in comparison. The laterally protruding guide ribs centre the dowel in the middle of the Domino routing and thus ensure perfect alignment of the workpieces. Specially shaped glue pockets and longitudinal grooves distribute the glue evenly for an optimum joint. Excess glue can escape through the lateral longitudinal grooves. 100 % torsion-proof from the very first Domino dowel. Quickly find the right dowel thanks to embossed size information. The special shape in combination with swelling glue pockets and longitudinal grooves gives the dowels a secure hold. For absolutely torsion-proof connections and maximum stability. And with significantly faster processing: the first dowel hole is very easily aligned and milled to a precise fit with the help of stop flaps. It immediately fixes the workpieces to be joined precisely and flush with the edge. The Domino system also tolerates minor inaccuracies in the other dowel holes.
