ABSTRACT:
Strips of wood for forming picture frames are attached to extruded members of metal or other rigid material provided with undercut channels. The strips and metal members are mitered at their ends and the mitered ends of composite strips are butted together to form a corner of the frame. A conventional L-shaped rigid member extends into both adjacent channels, spanning the miter joint and locks the metal members together to also hold the wood strips in secure abutment and at the proper angle without the use of any fasteners or adhesives in or on the wood itself at the mitered surfaces.
