Coronavirus update: we remain open and will continue to dispatch and accept orders; although in light of the new guidance we will be operating with a reduced number of staff. We are also reliant on the positions of our suppliers and couriers so our service may be affected by future changes in their circumstances.

We cannot accept walk-in custom at this time. Custom manufactured grilles and louvres are not currently available due to a manufacturer shutdown.

Please use the drop down menus below to select duct length, cravat width, and the connection methods required (we recommend Doby frames as a general connection method, certainly for larger ducts).

The default cravat slope angle will be approx. 35° regardless of size. Please use the "Any other info" box if you'd like to request a change to this angle.

Please use the 'Any other info' box to fine tune the size if necessary.
