A pair of non-parallel edges on opposite sides of the main body structure facing away from each other and extending along the main body structure and nearly intersect to form a vertex at a front portion of the main body structure. Another edge extending between the non-parallel edges at a back portion of the main body structure. An elastic strap for removably elastically securing the main body structure to the hinge member, where the removable elastic securing strap has the characteristic of adjustably positioning the vertex of the main body structure in adjacency with the hinge member when the bi-fold door structure is in an open position. A non-slip surface portion located along the main body structure co-extensive with the pair of non-parallel edges thereby aiding to maintain an operational wedge-stopped position. The removable elastic securing strap further havin…
