The ducting has a wire helix to keep it open in use, and a "cuff" at either end which is simply coupled to another length of ducting or equipment using a coupling band (supplied). Standard ducting length is 8 metres, available in 205 and 310mm diameter. Subject to prior request the ducting can be supplied with metal pigtail hooks along its length if you wish to suspend it above the ground.

High temperature resistant ducting is also available where the application involves extraction of engine exhaust gases.
