Tips

For a secure installation, always use compatible SL Rack clamps and fasteners (sold separately). Inspect the rail for any transport damage before mounting, and ensure the supporting structure is level and properly anchored. When cutting the rail to size, use appropriate tools for aluminum and deburr the edges to prevent module damage. Regularly check the anodized surface for signs of wear, and clean with mild detergent if needed to maintain appearance and performance.
