What to order?
The TCR Sun Tunnel Skylight is constructed as a modular system that allows you to purchase only the required components for your individual project.
Notes:

- Run length calculated based on vertical drop.
- Run length accounts for standard 2" overlap between components.
Review: These tubular skylights can provide an inexpensive natural daylight option for office spaces and even general warehouse areas. They tie into drop ceilings very nicely.
There often are electrical and mechanical conduits inside the roof structure to be considered. Close inspection of these areas prior to installation, is important, to completely understand all the work that will be necessary for an installation.
