LUMINES 12-0445-10 is a silver aluminium end cap for the LARGO M1 mounting profile. It closes the end of that profile while providing an opening for the power cable to pass through.
Choose the LARGO M1 version
The manufacturer distinguishes between caps for the LARGO profile, the LARGO M1 mounting profile and the combined LARGO M1 + LARGO assembly. This article is the LARGO M1 version, not the joint end cap for both assembled profiles. Check the full designation of the component you need to finish rather than relying on the LARGO family name alone.
Article 12-0445-10 identifies the silver version with a hole; it is different from the closed 12-0445-11 version. The manufacturer's photograph shows two side mounting holes and cutouts along the upper edge. The specified colour and material describe the cap itself. Other lighting-system components must be selected to suit the intended assembly.
