Expert Verdict — Reviewed by the SuperArbor Pro Desk
Route flexible tunnel in as straight and short a path as possible, since every bend reduces light output; keep the extension to the length you need and support it so it doesn't sag. Match the extension diameter to your TMF or TGF model before ordering. For very long runs or heavy obstruction, consider a rigid tunnel model instead.
Work in attic and roof spaces carefully: wear a dust mask and gloves, watch for roofing nails, and use fall protection when working on the roof.
Order the VELUX ZTF Flexible Sun Tunnel Extension to route daylight around attic obstructions with your TMF or TGF Sun Tunnel.
