A finger joint, commonly known as a comb joint, is a type of woodworking node that is made by cutting a set of complementary, interlocking patterns in two pieces of wood and then glueing them together. Rubberwood is one of the materials that may be used to make them.

Finger joint rubber wood boards are made from treated rubberwood which are kiln dried, finger jointed, edge glued, cold-pressed and sanded to make sheets of ready to use panel boards. The finger-jointing technique used for the production of high-quality edge-glued panels provides the same strength properties as any solid wood with the added benefit of dimensional stability.
