Diversified Tunnel Shutters

Tunnel Shutters® are the optimal solution for allowing smooth laminar airflow into the house with no door turbulence—aiding with ventilation while also preventing air leaking for significant energy savings.

The Tunnel Shutters’ maintenance-free rack and pinion drive system eliminates the need for cord or cable adjustments, and the innovative design allows the shutters to open to the outside–eliminating operating issues common with curtain and tunnel door systems.
