Ventilation Ducting  | Rectangular Ductwork | Straight Duct Lengths  | Dim A 300mm |  75mm

Rectangular Duct Straight 300x75mm

Use the drop-down menus below to select the length and connection methods. Doby frames or slip joints are standard connections for duct assembly. Sheet metal flanges are not a general connection method but can be useful when fixing to walls or ventilation equipment.

Although selectable on all sizes - and possibly necessary on your particular installation - we do not recommend slip joints for general duct assembly on ducts over 400mm in any one dimension.

A 'capped end' means that end will be blanked off; useful, for example, at the end of a run of duct.

These ducts are all made to order, so if you wish to make minor changes to the sizes, please use the 'other info' box below.
