Pleated shades can rattle against the window frame once the rig is moving, and these RV Designer hold downs are made to stop that. Each one uses a tie-cord that threads through the shade, then twists to tighten and lock the shade in place.
They come as a 2-pack with mounting fasteners included, so you can outfit a window in one go.
Made for use with pleated day/night shades; check that the cord routes cleanly through your shade's existing holes before mounting.
