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.

Use the drop down menus below to select the height and depth required. A depth of 100mm is common for these saddles, but it's not unsual to see them deeper.

Note if the grilles to be installed will carry a damper you should avoid a 50mm deep saddle - the extra depth of the grille/damper combination will mean the damper will encroach into the main duct, restricting airflow.

Use the radio buttons to select flange type. A 25mm internal flange is usual on these saddles. Please note that this internal flange has the effect of reducing the duct size by 50mm; consideration therefore needs to be made when matching the grille to the saddle e.g. a 400x150 grille will require a 450x200 saddle. With a 20mm external flange this does not apply i.e. the grille size must match the duct size e.g. a 400x150 grille will require a 400x150 saddle.
