Due to a high volume of orders there will be a 2 week delay in all custom manufactured ductwork. This includes all rectangular ductwork, grille boxes, and fabricated round fittings. This does not affect our stock items. We apologise for any inconvenience may cause.

450mm

650mm Width x 450mm Depth Symmetrical Taper
SYMTPR-650-450

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.
