A picture hanging system may be mounted to the wall, but you could also opt to mount it on the ceiling. The flexible picture hanging system Top Rail is ideal for this purpose. This ceiling rail is discreet in its dimensions (14.3 mm x 7 mm), and is available in white, aluminium and black. The Top Rail is an ideal hanging system to use in combination with recessed ceilings. By mounting the ceiling rail to the wooden side strip of a recessed ceiling, the rail ‘disappears’ into the ceiling. This ‘invisible’ picture hanging system (hidden in the shadowline next to the recessed ceiling) then offers a flexible way to hang, change and replace pictures and wall decorations throughout the entire room.
