Installation & Care

To maintain the high-quality black finish of your extrusion, please follow these professional care guidelines:

  • Cleaning: Use a soft, lint-free cloth with warm water and a mild, pH-neutral detergent. Avoid acidic or alkaline cleaners which can damage the anodized layer.
  • Tooling: When assembling, use plastic-coated or high-quality hex keys to prevent scratching the inner tracks.
  • Cutting: If you perform secondary cuts, use a carbide-tipped non-ferrous blade. Note that the cut face will expose raw aluminum; this can be touched up with a matte black paint pen if required.
  • Storage: Store rails horizontally in a dry environment to prevent surface contamination or bowing over long periods.
