650mm

750mm Width x 650mm Depth Offset Taper
TFTPR750-650

Use the drop down menus below to select the width out, and connections.

If you wish to specify a certain total length for the taper please use the 'Other info' box below (there may be an extra charge if there is a substantial divergence from the default length).

Connections A and B refer to the connection methods to be used on either end of the taper. 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 connecting 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.
