ABSTRACT:
A screen or patio door adapted for sliding along a track in a doorway or other opening includes a generally rectangular frame of extruded aluminum channel having four generally L-shaped corners, at least two of the corners positioned along the bottom of the door and adapted to slide along the track. Each corner is formed by a 90.degree. miter cut leaving a web of aluminum material bridging the cut, and thereafter bending the channel about the web to form the corner. The corners all include a corner lock extending through the channel and bridging the miter, with fasteners extending through the channel. The fasteners extend through and expand the corner lock to fill the channel, thereby forming an inside wall bridging the miter cut and unitizing the corner construction.
