Know before you buy
Yes, the ducting is designed to be cut to your desired length. You can easily trim the steel-wire spiral and the outer layers using standard wire cutters and a utility knife.
The internal aluminum foil layer is fire and flame resistant, making it safe for standard HVAC and ventilation setups. However, it is not intended for direct contact with open flames or extremely high-temperature exhaust sources like wood stoves.

The integrated steel-wire spiral allows the ducting to bend and maneuver easily around obstacles. While it is highly flexible, avoid sharp 90-degree kinks to maintain optimal airflow and prevent pressure drops.
Yes, the outer PVC layer acts as a protective barrier against moisture and environmental wear. It is specifically designed to withstand the conditions found in hydroponic grow rooms and attics.
