Shelf base carrier comprising distancing elements

A shelf base carrier which can be suspended or inserted into a vertical wall rail, comprising a lower holding portion with a bearing surface, which extends at a upper edge thereof horizontally away from a wall the bearing surface extending horizontally a first length, for a shelf base and a clamping element, extending away above the wall, for clamping the shelf base at the trailing end thereof facing the wall,

• having a lower distancing element which can be detachably attached to the lower holding portion and an upper distancing element which can be detachably attached to the clamping element, wherein the lower distancing element can be attached in a first and a second position, in the first position a first, smaller spacing and in the second position a second, larger spacing between the bearing surface of the lower portion and a contact surface of the lower distancing element being defined by the held shelf base, wherein an upper part includes a portion of the bearing surface and at least a portion of each of three contiguous sides of the lower holding portion, the three contiguous sides disposed adjacent to the bearing surface
• wherein the lower distancing element has a first recess on one side thereof and a second recess on the opposite side thereof, for receiving the upper part of the lower holding portion in the first and second positions, respectively, and
• wherein a depth of the first recess is larger than a depth of the second recess, both recesses extending, in a position when attached to the upper part of the lower holding portion, in a direction perpendicularly away from the wall.
