Screw for mounting clip to fix the 35x35 recessed profile in a false ceiling.

The clip should be lightly screwed onto the profile before inserting the profile into the false ceiling, just enough to hold it in place. Once the profile is inserted into the groove of the false ceiling, tighten the screws further to firmly press the edges of the profile against the ceiling.

Only then, the LED strip should be placed at the bottom of the profile, and then the custom luminaire will be closed by clipping on the diffuser.
