ABSTRACT:
A hanging file support frame has a pair of file folder support rails and four corner fittings mounted on legs. Each corner fitting has a bottom wall, a rear wall and a flexible top wall forming a first opening for the reception of one end of a rail. The top and bottom walls form a front entry into the first opening for the passage of said one end of a rail into said first opening in a direction transverse to the length of the rail. The rear wall is substantially thicker than the top wall and the top wall is cantilevered from the rear portion of the rear wall. Flanges releasably lock the rail end into the first opening. A transverse member having hollow ends has one end passing through a second opening in the rear wall. A rail backing wall in the first opening of each corner fitting depends from the top wall and has a boss extending toward the second opening and received in the hollow end of a transverse member for restraining the movement of the depending wall and the top wall to prevent inadvertent disengagement of a rail end from the corner fitting.
