The rail is affixed quite firmly to the clips because it must be fastened safely and securely. The system is essentially designed to be mounted once. If you disassemble all the parts, it is important that you carefully examine each component and replace any damaged parts. After you disassemble the system, you must always replace the clips and plugs with new ones.
The best way to remove the rail from the clips is by loosening the rail from the clip at the bottom (directly on the clip) using a flat screwdriver. You must start on one of the sides and then work from there to the left or right. In order to prevent wall damage (or at least keep it to a minimum), we recommend that you place a steel or aluminium sheet beneath the screwdriver. Depending on the type of wall, you can then prevent the plug from being pulled out of the wall.
