20120227214 | WALL CLIP AND SHIM ADAPTED FOR INSULATING CONCRETE WALLS AND SIMILAR MATERIALS - A stackable shim system. A first shim includes a receiving feature, an attachment feature, and a main portion having a first thickness. A second shim also includes a receiving feature, an attachment feature, and a main portion having a second thickness. The receiving feature of each shim is configured to engage with the attachment feature of the other shim such that either shim can be removably attached to the other to create a stacked shim having a main portion having a thickness that is the sum of the first and second thicknesses. The shims may be conveniently used for taking up space and/or accommodating for irregularities in construction materials. | 09-13-2012 |
