Spiral Duct Grilles
SGR1

Spiral duct grilles, as the name suggests, are designed to be installed directly on to exposed spiral duct. They are manufactured from galvanised mild steel and so have a similar appearance to the duct itself; this results in a stylish industrial finish that is regularly seen within 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 400mm dia to above.

Available sizes are listed height x length.

Please allow 1-3 days.
