A mounting assembly is provided for securing an element to a wall structure having a laminate outer cover residing adjacent to an internal thickness of compressible material. The assembly includes an anchor for engaging the wall structure and comprising a threaded outer wall for securing the anchor within the wall thickness, an elongated internal passageway for receiving an extent of an elongated fastener, and a deformable upper crown arranged about an open end of the passageway; a strut assembly coupled to the supported element; and an elongated fastener for securing the strut assembly to the anchor and wall structure. Other embodiments include a fastener assembly kit comprising a plurality of separate components to be assembled together to mount a strut member to a laminated foam wall panel, the components including an anchor, a washer assembly, a spacer, and an elongated fastener for securing the components to the wall panel.

Systems and method for supporting a cover material to a support material include a coupling device that includes an inner coupler and an outer coupler. The inner coupler and the outer coupler are separably joined. The inner coupler may be attached to the support material, and the outer coupler may be attached to the cover material.
