Abstract: An adjustable support assembly particularly for use in supporting the bottom shelf in a household refrigerator including a support bracket having a hollow cylindrical sleeve with an interior circumferential surface having a first longitudinal portion with an array of inwardly directed elongated tooth projections along and substantially perpendicular to the longitudinal axis of the sleeve and a second longitudinal smooth portion adjacent the first portion. There is a brace having an outside diameter slightly smaller than the inside diameter of the sleeve and has a circumferential outer surface with a first longitudinal portion with an array of outwardly directed elongated tooth projections along and substantially perpendicular to the longitudinal axis of the brace and a second longitudinal smooth portion adjacent the first portion, said projections on the first portion being complementary to the tooth projections on the first portion of the interior surface of the sleeve.
