No need for saddle adaptors. Variety of models available. A cost effective solution to spiral duct mounted ventilation, series RGS are made from entirely galavanised steel and are designed to fit perfectly onto spiral ducting. Standard finish is bare steel with powder coating to any RAL/BS colour available. RGS is a rectangular ventilation grille with vertical adjustable bars for direct installation in circular ducts. The grille can be used for both supply and exhaust air. The grille can be supplied with horizontal directional bars, straight or slanting sliding damper or blade damper. The grille is designed so that the grille flanges always fit tight to the duct regardless of the duct diameter. RGS is made of hot-galvanised steel plate and is put together without welding. This means that the grille can be used without further surface treatment. The exterior of the grille thus matches the duct surface.
