Spiral Duct Grilles

Ventilation Ducting  | Ventilation Grilles & Louvres | Grilles & Louvres Stock | Spiral Duct Grilles & Dampers |  Spiral Duct Grilles



Spiral duct grilles are designed to be installed directly onto exposed spiral duct. They are manufactured from galvanised mild steel and have a similar appearance to the duct itself. This results in a stylish industrial finish that is regularly seen as part of the ventilation systems of many commercial establishments.

Fixing screws are included.

Grilles with a height of:
75mm are best suited to ducts of 150mm dia to 355mm dia.
125mm are best suited to ducts of 250mm dia to 710mm dia.
225mm are best suited to ducts of 450mm dia to above.

Available sizes are listed length x height.
