A variable width hanging file frame system is equipped with adjustable corners permitting installation in either letter-sized or legal sized drawers. The system comprises two side rails, two cross member rods and two hoops joined by adjustable corners. The hoops support the frame and terminate in horizontal tangs having barbs. The corners comprise separate pieces that are slidably coupled together; one piece is connected to the side rail, and the other piece receives the rod and hoop. Each corner comprises a generally rectangular body and a slider. The body comprises a slot and minor bosses that are horizontal and parallel to one another. They receive the end portion of the rods and hoops. Barbs in the hoop tangs index with keyways defined in the minor bosses to prevent torsional movement of the hoops. The slot has a generally trapezoidal cross section and receives the slider. The slider comprises an arm having a generally trapezoidal cross section. An elongated major boss integrally formed on one end of the arm receives an end of a side rail. A shoulder bordering the major boss acts as a stop when the slider is fully retracted and the shoulder contacts the body. The distal end of the arm is slightly enlarged to wedgably retard movement of the slider at the extended extreme.
