Securing Flexible Duct

Flexible duct must be installed with supports at maximum intervals of 1.5 metres. Flexible ductwork can be 
supported by using gaffer or electrical tape, provided that it does not restrict the internal diameter of the 
ducting. Ducting installed looped over hanging beams should be installed in such a manner as to ensure the 
changes of direction are gradual. Support of the ducting with the use of hangers may be required, see option 2. 

NOTE:

 Ducting should be kept taut at all times.

Figure 9 Examples of securing ducting

Option 1

Secure the flexible duct 
to the beam

Option 2

Support flexible duct 
by using hangers.

NOTE:

 Care shall be 

taken to minimize 
sagging or snaking 
of the duct between 
supports.
