Setup, Compatibility & Care
To install, simply align the extension tube with the existing tunnel section and push until the integrated clips lock into place. No screws are required. Ensure the joints are perfectly flush to avoid any light leakage or shadows inside the tube.
Compatibility: This unit is exclusively designed for 10-inch (approx. 250mm) rigid diameter Velux Sun Tunnel systems.
Care: The interior reflective surface should never be cleaned with abrasive cloths or harsh chemicals. If dust accumulates during installation, use a soft, dry, lint-free cloth to gently wipe the surface. Avoid bending or denting the metal, as structural damage to the tube can disrupt the path of light reflection.
