The clip for the aluminum LED profile is an additional mounting element designed for profiles 41010A1 and 41010A2. Simply screw the plastic holder to a flat surface, then snap the aluminum profile with the LED strip into it by gently pressing it in.
For proper functioning, it is important to install all clips in the same plane. If the mounting surface is uneven or the holders are not aligned, the profile may not snap in correctly and may not hold firmly in the desired position.
