A wall bracket for the support of a shelf, a table or a bench is fastened to a lipped box channel that is vertically positioned with its open slit towards the shelf; it is held in the channel by friction forces only and can be readily moved up and down and held at any desired height of the channel. The bracket end which is inserted into the channel through its slit has a horizontal rectangular top portion smaller than the channel inside, but wider than the slit, and is connected to the bracket body outside the channel by a neck portion of a width narrower than the slit, while the bottom portion is in the shape of a horizontal spike passing into the channel through the said slit and pressed against the channel rear by the load acting on the bracket. The bracket is inserted into, or withdrawn from the channel by turning it until its top portion is vertical and parallel with the slit and can be pushed through it.
