ABSTRACT:
Quick-assembly picture frames constructed from mitered frame sections (2) have unsightly join lines (6) at their corners. The appearance of such frames is enhanced by fitting a decorative corner unit (8) onto the frame corners which conceals join line (6). The corner unit is secured to the frame e.g. by tightening a grub-screw threaded through a wall (12) of the unit (8) against the rear surface (5) of the frame.
