Thanks to the undercut rib, the connector can be inserted into the groove by hand in seconds without tools. It is ideal for aesthetic constructions such as dismountable furniture connections, surface, corner, and middle wall connections. The profile groove is milled into the surface or edge on a CNC machine or with the Lamello Zeta using a disc cutter with lateral undercut ribs. Due to the low installation depth, mitres at all angles are possible, as no parts protrude from the surface, allowing the workpieces to be stacked without any problems.
