Replacement part for Domino Joiners. The Base Support Bracket now includes integrated index stops, providing accurate reference points for mortising near the edge of a workpiece. This is particularly useful for narrow workpieces. When using the flip stops, the center of the cut is 20mm (25/32") from the edge versus 37mm (1-15/32") without. The flip stops offer optimal flexibility when using the new 4mm Domino cutter and tenons.
