Abstract: A shelf bracket is disclosed which is adapted to be attached to a rectangular pole structure. The bracket is comprised of a pair of spaced parallel arms having inner and outer ends which are adapted to embrace the side of the pole upon which the bracket is mounted. A fixed cross member extends laterally between the arms and is adapted to engage the forward or outer face of the pole. A fastening means detachably extends between said arms at the inner ends thereof. A pair of sockets is mounted on the outer side of each arm and is adapted to receive the ends of a stringer member for purposes of supporting a shelf surface. The upper ends of the sockets terminate in the plane of the upper portions of the arms.
