Thanks to the end stop, the PROLED profile S-Line Gallery can neither be moved nor lifted out of the mounting profile. All you need is these accessories and some time for the simple assembly. 

First, fix the locking bracket using the enclosed perforated plate at the start or end of the Mounting profile. The mounting of the angle should be flush and butt joint. The supplied hexagon socket screw ensures a non-slip hold without play. This must be tightened through a self-performed hole in the LED profile S-Line Gallery.
