A picture hanging system consists of a hanging rail, hanging wires and hooks. The picture hanging system may be mounted to the wall or ceiling. If you are going to mount it to the ceiling, the rail is mounted to the concrete of the ceiling or next to a recessed ceiling. With a picture hanging system on the ceiling, your walls can be decorated in a flexible way by inserting the hanging wires with hooks any where you like in the rail. Up Rail mounts to the ceiling using clips and Top Rail is mostly used in combination with a recessed ceiling.
