Abstract: A mounting apparatus providing a horizontal shelf for securely stacking one component, such as a VCR, over a second component, such as a video display. The apparatus has struts which extend downwards from the sides of the shelf to flank the second component when the shelf is placed on top of it. An attachment mechanism in each strut is adjusted to clamp the apparatus securely to the second component. Upward struts may also be provided with similar attachment mechanisms to secure the stacked component to the shelf. The apparatus can be formed a single molded piece or have removable struts which are positioned as needed. The shelf can be a single component or be divided lengthwise and connected in a manner allowing for an adjustable depth.
