The HR-ALU profile from KLUS is a channel designed to be mounted directly into bathrooms, showers, hallways, walkways, gardens, and patios. The sleek design and frosted cover create a desirable lighting effect that can be added to virtually any space. Using proper waterproofing techniques this channel can achieve an IP67 rating for wet or damp environments. To seal the HR-ALU extrusion we recommend using DOW CORNING 3145 , transparent Neutral Silicone, see video link below for reference.
