In-door cooler rack shelving system

A method of adjusting a shelf assembly of a stand-alone in-door cooler rack shelving system, the system comprising:

• at least four uprights comprising a pair of front uprights and a pair of rear uprights, wherein each upright comprises a plurality of openings arranged in a row along a length of a surface of each upright;
• at least two cross-members, wherein one cross-member is disposed between a first front upright and a first rear upright to form a first shelf support, and wherein one cross-member is disposed between a second front upright and a second rear upright to form a second shelf support;
• and
• at least one shelf assembly comprising a wire shelf having a top surface, a bottom surface, and a first plurality of at least four prongs disposed in at least four of the plurality of openings, wherein at least two prongs of the first plurality of prongs proximal a front of the wire shelf are longer than remaining prongs disposed on the wire shelf, wherein the method comprises:
• sliding the wire shelf in a direction to disengage all of the prongs except the at least two prongs proximal the front of the wire shelf from the openings;
• pivoting the wire shelf about the at least two prongs proximal the front of the wire shelf to change an angle at which the wire shelf is disposed;
• selecting openings to provide a different angle to dispose the wire shelf;
• sliding the wire shelf in a direction to engage all of the prongs in the selected openings to obtain the selected different angle.
