The mesh screen is vinyl-coated steel, rigid enough to keep out even the most industrious squirrel. The box frame adaptor allows for mounting on module frames that lack a flange to mount to (1 per clip). Installs on perimeter of solar array between solar panels and the roof. Easily cut to desired length. 100 linear ft. kit with 36 clips.
