Description
Spiral Grilles in 525mm × 125mm — double deflection grilles made to mount directly onto round spiral ducting, available for next day delivery.
Where supply air needs to be delivered straight from exposed spiral ductwork — warehouses, retail units, studios and offices with visible services — a spiral-mounted double deflection grille is the neat solution. The grille fits the curve of the duct face, and its two rows of adjustable blades let you direct the airstream both horizontally and vertically, so throw and spread can be tuned to the space during commissioning.
Key features
- 525mm × 125mm face size
