The invisible fitting
The totally concealed VB insert connects size 38 or 50 lightweight boards with 4 mm thick face layers. A hole drilled into the end face is all that is needed for its use, thus saving time in relation to surface cutting. The glue for the VB insert is applied at two points from which it simultaneously flows through special glue channels to both face layers, securing the fitting. Ideal distribution of forces ensures that the finished product can withstand heavy loads.
