A laterally adjustable cantilever shelf system for a refrigerator/freezer includes a formed metal bracket which defines a continuous channel. The bracket includes hooks to engage into slots in shelf standards in a refrigerated compartment. This enables the bracket to be placed at any select vertical position within the compartment. A shelf accessory includes sheet metal side arms each having a hook at the top rear that mates with a channel in the bracket to retain the shelf. Sufficient clearance is provided between the shelf side arm and the channel to allow the shelf to be moved by slightly lifting the front of the shelf to relieve the pressure between the top hook and the channel and applying lateral pressure. An additional hook at the bottom of the side arm interferes with the channel when the front of the shelf is lifted to prevent the shelf from becoming accidentally dislodged. The storage accessory is removed by raising the rear of the shelf, tipping the bottom hook of the side arm out of the channel and then tipping the top hook out of the channel.
