The white LUMINES Y mounting clip, article 13-0081-00, secures an LED profile from the Y system. This is the basic plastic version, not the metal Y bracket. Its open shape has two side walls and an opening in the base.
Clip-in profile mounting
The profile clicks into the holder. This mounting method does not require drilling through the profile itself, offering an alternative to fixing the profile directly. The base opening is visible in the product photograph; choosing a fixing suitable for the support surface is a separate question from profile compatibility.
Choosing the Y-system version
Check the designation of your profile before ordering: the manufacturer assigns this clip to system Y. White refers to this particular version, not an assortment of finishes. Article 13-0081-00 distinguishes it from the black, transparent and metal mounting clips in the same family. This is a mounting component for an LED-profile system, rather than a standalone light fitting.
