and a disk-shaped rotatable cam mounted to a second end of the body portion opposite to the first end, wherein a radius of the cam is variable relative to a mounting point of the cam, and further wherein an outer edge of the cam rests on the mounting device such that rotating, the cam about the mounting point adjusts an angle of the top surface, wherein the second tang includes a first recessed elongated contact surface, wherein the first recessed elongated contact surface maintains contact with a bottom surface of the second aperture of the mounting device such the rotation of the angle bracket about the first tang when the cam is rotated is effectuated. ### Claim 2 (depends on 1) The angle bracket of claim 1, further including a third tang protruding from the body portion, the third tang having a fourth contact member, wherein the third tang is located proximate to the end of the body portion where the rotatable cam is mounted. ### Claim 3 (depends on 2) The angle bracket of claim 2, wherein the third tang includes a second recessed elongated contact surface that maintains contact with the bottom surface of a third aperture of the mounting device. ### Claim 4 (depends on 1) The angle bracket of claim 1, wherein the outer edge of the cam includes as plurality of flat edges, wherein the flat edges are each perpendicular to a shortest path from each respective flat edge to the mounting point, and such that the perpendicular distance from the mounting point to each of the plurality of flat edges is unique. ### Claim 5 (depends on 1) The angle bracket of claim 1, wherein the cam includes a single, continuous outside edge. ### Claim 6 (depends on 1) The angle bracket of claim 1, wherein the cam is fastened to a cam arm with an attaching means. ### Claim 7 (depends on 6) The angle bracket of claim 6, wherein the cam arm extends from the body portion of the bracket. ### Claim 8 (depends on 6) The angle bracket of claim 6, wherein the attaching means includes an assembly pin, a spring washer, and a snap ring, and the attaching means attaches the cam to the cam arm through a cam aperture. ### Claim 9 (depends on 2) The angle bracket of claim 2, further comprising a plurality of shelf coupling apertures configured on the body portion of the bracket opposite the first, second and third tangs, such that the shelf coupling apertures accommodate a plurality of shelving systems. ### Claim 10 (depends on 1) The angle bracket of claim 1, wherein the mounting device includes a plurality of apertures. ### Claim 11 (depends on 1) The angle bracket of claim 1, further including a plurality of angle indicators positioned on the cam that communicate to a user corresponding angles of the lop surface of the body portion. ### Claim 12 An angle bracket, comprising: an adjustable angle top surface of a first end of the angle bracket configured to support a shelving unit; a first tang protruding from the angle bracket, the first tang having a first contact member and a second contact member, wherein the first and second contact members engage a first aperture of a mounting, device; a second tang protruding from the angle bracket, the second tang having a third contact member, wherein the third contact member engages a second aperture of the mounting device; a third tang protruding from the angle bracket having a fourth contact member, wherein the second and third tangs include first and second recessed elongated contact surfaces; and a disk-shaped rotatable cam mounted to a second end of the angle bracket opposite the first end, wherein a radius of the cam is variable relative to a mounting point of the cam, and further wherein an outer edge of the cam rests on the mounting device such that rotating the cam about its mounting point adjusts an angle of the top surface, and the first and second recessed elongated contact surfaces of the second and third tangs maintain contact with a bottom surface of the second aperture and a third aperture of the mounting device. ### Claim 13 (depends on 12) The angle bracket of claim 12, wherein the outer edge of the cam includes a plurality of flat edges, wherein each of the flat edges are perpendicular to a shortest path from each respective flat edge to the mounting point, and such that the perpendicular distance from the mounting point to each of the plurality of flat edges is unique. ### Claim 14 (depends on 12) The angle bracket of claim 12, wherein the cam includes a single, continuous outside edge. ### Claim 15 (depends on 12) The angle bracket of claim 12, wherein the cam is fastened to a cam arm with an attaching means. ### Claim 16 (depends on 15) The angle bracket of claim 15, wherein the cam arm extends from the body portion of the bracket. ### Claim 17 (depends on 15) The angle bracket of claim 15, wherein the attaching, means includes an assembly pin, a spring washer, and a snap ring, and the attaching means attaches the cam to the cam arm through a cam aperture. ### Claim 18 (depends on 12) The angle bracket of claim 12, further comprising a plurality of shelf coupling apertures configured on the body portion of the bracket opposite the first, second and third tangs, such that the shelf coupling apertures accommodate a plurality of shelving systems. ### Claim 19 (depends on 12) The angle bracket of claim 12, further including a plurality of angle indicators positioned on the cam that communicate to a user corresponding angles of the top surface of the body portion. ### Claim 20 An angle bracket, comprising: a body portion having a top surface in a first end of the body portion configured to support a shelving unit; a first tang protruding from the body portion, the first tang having as first contact member and a second contact member, wherein the first and second contact members engage a first aperture of a mounting device; a second tang protruding from the body portion, the second tang having a third contact member, wherein the third contact member engages a second aperture of the mounting device, wherein the first and second tangs secure the bracket to the mounting device; a third tang protruding from the body portion, the third tang having a fourth contact member, a disk-shaped rotatable cam mounted to a second end of the body portion opposite to the first end, wherein the outer edge of the cam includes a plurality of flat edges, wherein each of the flat edges are perpendicular to the shortest path from each respective flat edge to the mounting point, and such that the perpendicular distance from the mounting point to each of the plurality of flat edges is unique;
