Grilles in this section are manufactured to order to customer requirements. Delivery is typically 5-6 working days. We also hold commonly used square-shaped double deflection grilles in stock. They can be found here.
Includes an pre-fixed aluminium opposed blade damper. Dampers are adjustable by way of a screwdriver slot accessible through the grille face.
Manufactured from extruded aluminium alloy.
All grilles supplied with frames pre-punched for fixing, screws included.
Please note that the sizes stated refer to the duct size, or neck size of the grille. It does not include the flange. Sizes stated are nominal and refer to the aperture they are designed to fit. Actual size is 6mm smaller than the nominal size. These grilles have a 25mm flange, therefore the overall size of the grille is 50mm bigger than the actual size, and 44mm bigger than the nominal.
Example: A 200x200 grille is designed to fit a 200x200 aperture. It's actual size is 194x194. It has a 25mm flange, so its overall size is 244x244mm.
