Abstract: A liner (interchangeable) for each end bracket of a louver assembly, the liner consisting of a flat strip with longitudinal edge abutment and U-bent at each end to embrace the end margins of the louver pane or panel, with either inturned U-arm disposed to transversely receive a resilient U-shaped retainer jointly embracing the respective arm and adjacent bracket wall, with contact anchorage means carried on both the bent arm and retainer so as to jointly prevent external displacement of the liner (and its embraced louver panel) from the end brackets.
