An improved adjustable rib for use with an awning support apparatus which in turn is used with an awning having one end attached to a wall and a second end attached to an awning support tube held a predetermined distance from one end of the awning, measured along the awning, by a pair of side frames attached to the wall. The improved adjustable rib includes an elongated rigid bowed housing having two open ends. Elongated and rigid flat bars, having a curvature nearly identical to that of the housing, slide within the housing and are adjustable to vary the length of the rib. Lock screws, which are screwed into a hole in each of the flat bars, are used to fix the position of the flat bars within the housing. In a second embodiment, the rib includes a smaller diameter curved tube which telescopically fits into a larger curved diameter tube having the same curvature as the smaller tube.
