Box joint
From Wikipedia, the free encyclopedia
A box joint is a woodworking joint made by cutting a set of complementary, interlocking profiles in two pieces of wood, which are then joined (usually) at right angles, usually glued. The glued box joint has a high glued surface area resulting in a strong bond, on a similar principle to a finger joint. Box joints are used for corners of boxes or box-like constructions, hence the name. The joint does not have the same interlocking properties as a dovetail joint, but is much simpler to make, and can be mass-produced fairly easily.
Box joints are generally created by using the same profile but displaced for both halves. In modern workshops these are often made on table saws,[1] sometimes using a dado set. Custom machinery can cut the entire joint in one pass, using a suitable jig multiple pieces, even of opposing senses, can be cut at once. They were traditionally produced manually using a tenon saw and chisel, and fine cabinet makers still use these methods. Jigs can also be used, as with dovetails, to help produce a consistent result.
