ABSTRACT:
An adjustable shelf support having a standard with a shelf bracket capable of infinite adjustability. The standard has a L-shaped cross section, a first leg of the `L` lying along the supporting surface and a second leg extending outwardly therefrom. The free end of the second leg is folded back towards the first leg forming two parallel, spaced extensions. The bracket is planar with two fingers extending outwardly from but parallel to the plane of the bracket. The upper finger is inserted behind the free end of the second leg by rotating the bracket downward. This brings the flat trailing edge between two protrusions formed on the first arm and allows the second finger to snap into place behind the free end of the second leg, thereby, preventing accidental dislodgement by an upward force. The distance between the flat trailing edge and the farthest extent of the first protrusion slightly exceeds the length of the inner wall of the second leg. In engaged position, the bracket is firmly wedged and maintained in place by frictional forces.
