The Shadowline rail – drywall enables the placement of an invisible picture hanging system between plasterboard walls and ceiling panels. A discreet shadow line is the only element that appears between the wall and ceiling, and this is where the flexible picture hanging system is hidden. It is possible to install a hanging cord in the rail, anywhere you like in the room. Since the rail itself isn’t visible, the hanging cords are suspended directly from the ceiling. If you choose the transparent perlon hanging cords for the rail, you will have the most discreet picture hanging system at your disposal. Using the Shadowline ceiling system means you will always have a guarantee of smooth, clean walls, and the flexibility to decorate them any way you like, without the need for tools.
