The installation is simple and done below the ceiling on the wall. Once the railing system is mounted, you will be forever flexible changing pictures, paintings, posters, photos, mirrors or tapestry fast and easy. You don't need a craftsman anymore to change your pictures. The wall space around the pictures remains free of holes from nails or drills. Thanks to a special sliding stopper, pictures can be securely adjusted diagonally, like in the area of a stair-case or underneath the roof.
