A rack fastener adapted to engage, and be retained to, a first member and then hold a second member to the first member, comprising or including, a. A first stud having a first base portion, adapted to install from a back surface of the first member into a first aperture thereof, such that the first stud extends through the first aperture, and extends from a front surface of the first member, b. A second stud having a second base portion, adapted to install from the back surface of the first member into a second aperture thereof, such that the second stud extends through the second aperture, and extends from the front surface of the first member, the second stud parallel to, and co-extensive with, the first stud, the fastener characterized by comprising: c. A connecting portion connecting the first base portion to the second base portion, d. A clipping portion extending, directly or indirectly, from the first base portion, the clipping portion having at least one engagement face to engage a region of a third aperture of the first member so that the fastener is substantially prevented from being separated from the first member, e. Such that the first stud and second stud can pass through respective apertures of the second member, and thereafter a first fastener can engage the first stud, and a second fastener can engage the second stud to secure the second member to the first member. a.
