Abstract: A plurality of frost shields (50) are removably positioned about the upper circumferential expanse of the walls of the liner (20) of a refrigerated cabinet (10). The frost shields (50) are magnetically mountable to the liner (20) to facilitate ease of installation and removal. Each frost shield (50) is a pliable panel fabricated in a layered construction with a relatively thin observe layer (52) of vinyl mounted on nominally thicker back layer of thermoplastic material (54) impregnated with magnetic material (60). Each frost shield (50) may be provided with a pair of handles (70) inserted in their respective slots (58) formed through the frost shield panel.
