An elevator car wall includes a support construction formed of a grid structure with vertical and horizontal support rods and a surface construction formed of panels attached with panel fastening elements to the grid structure. A vertical seam profile with a U-shaped bottom portion and an I-shaped middle portion is positioned between panel rows and attached with seam profile fastening elements to the grid structure. The middle portion extends between the vertical edges of the panel rows. A portion of the panel fastening element extends into contact with an inside surface of a respective branch of the U-shaped bottom portion in order to secure the vertical side edge of the panel against the middle portion.

A photovoltaic panel wire cover assembly, used with a PV panel having a perimeter trim piece, includes clips, an elongate wire cover and fastener structure. Each clip includes a proximal end and long and short legs, the long leg parallel with and joined to the short leg at the clip proximal end. A gap between the long and short legs is sized for receipt of the trim piece. The wire cover includes a wire-covering housing defining a housing interior and having first and second opposite sides and a first flange extending from the first opposite side and positioned against the long leg. The fastener structure engages the short leg and the first flange to bias the first flange and the long leg therewith towards the short leg. The wire cover can be fastened to the trim piece through the clips without penetrating the PV panel.

A first example box nut retainer includes a support, a fastener sleeve, a first wing, and a second wing. The support has a base and a tab extending from the base. The fastener sleeve defines an opening and extends downwardly from the base. The first wing extends from the base and has a snap arm. The second wing extends from the base and overlaps the first wing.

Resilient mounting clips, panel mount systems including the same, and associated methods. A resilient mounting clip includes a support structure engagement portion and a panel engagement portion with a plurality of edge extensions and a plurality of outboard panel supports. Each outboard panel support extends from a respective edge extension. Each outboard panel support is configured to move at least substantially parallel to a compression axis when the respective edge extension resiliently flexes with respect to the support structure engagement portion. A panel mount system includes at least one support structure, at least one resilient mounting clip, and at least two panels received by each mounting clip. A method of assembling a panel mount system includes positioning and securing a resilient mounting clip on a support structure and receiving each of a first panel and a second panel with the resilient mounting clip.
