and the locking structure is configured to prevent the movement of the adjustment structure when the adjustment structure is in the third position and the fourth position. ### Claim 10 A bracket, comprising: a shelf support surface; a first projecting portion extending from an attachment side of the bracket, the first projecting portion including a notch; and a second projecting portion extending from the attachment side of the bracket, the second projecting portion including a proximal notch and a distal notch, wherein the notch in the first projecting portion and the proximal notch in the second projecting portion are positioned on a first line at a first angle with respect to the shelf support surface and the notch in the first projecting portion and the distal notch in the second projecting portion are positioned on a second line at a second angle with respect to the shelf support surface, wherein the first angle is different from the second angle. ### Claim 11 (depends on 10) The bracket of claim 10, wherein the first angle is substantially perpendicular to the shelf support surface and the second angle is approximately 15 degrees from perpendicular to the shelf support surface. ### Claim 12 (depends on 10) The bracket of claim 10, wherein an angled portion of the attachment side at an end thereof opposite the shelf support surface is at substantially the second angle with respect to the shelf support surface, wherein the second angle is other than substantially perpendicular to the shelf support surface. ### Claim 13 (depends on 10) The bracket of claim 10, further comprising: an adjustment structure comprising a plate attached to the bracket for rotational movement with respect to the bracket about an axis of rotation to move a first side of the plate between a first position and a second position, wherein the first side of the plate crosses the notch in the first projecting portion at a first angle substantially perpendicular to the shelf support surface to form a side of the notch at the first angle substantially perpendicular to the shelf support surface when the first side of the plate is in the first position and the first side of the plate crosses the notch in the first projecting portion at a second angle other than substantially perpendicular to the shelf support surface to form the side of the notch at the second angle other than substantially perpendicular to shelf support surface when the first side is in the second position; and a locking structure configured to prevent movement of the plate with respect to the bracket when the plate is in the first position and the second position. ### Claim 14 (depends on 13) The bracket of claim 13, wherein the locking structure comprises a button configured to extend at the same time through a first locking hole in the bracket and a first locking hole in the plate to prevent rotation of the plate with respect to the bracket when the plate is in the first position. ### Claim 15 (depends on 14) The bracket of claim 14, wherein the button is configured to extend at the same time through a second locking hole in the bracket and a second locking hole in the plate to prevent rotation of the plate with respect to the bracket when the plate is in the second position. ### Claim 16 (depends on 13) The bracket of claim 13, wherein: the plate comprises a second side, wherein a shortest distance from the axis of rotation to the first side is different from the shortest distance from the axis of rotation to the second side, wherein the second side is configured to cross the notch in the first projecting portion at the angle substantially perpendicular to the shelf support surface to form the side of the notch at the angle substantially perpendicular to the shelf support surface when the second side is in a third position and to cross the notch in the first projecting portion at the angle other than substantially perpendicular to the shelf support surface to form the side of the notch at the angle other than substantially perpendicular to the shelf support surface when the second side is in a fourth position;
