Grille. Min. - max. dimensions

Min. - max. dimensions H L 0 00 75 00 Standard grilles are available with mm pitch within the above min. and max. sizes. Customized sizes available on request. Description is an adjustable single or double deflection grille made of aluminium. With adjustable blades, the grille is very useful for air supply and can be adapted to the required throw and air spread pattern. The grille is available with several mounting options and can be delivered with mounting frame, opposed blade damper and plenum box accessories. LindQST Use the advanced Lindab web tool LindQST to calculate the full range of grilles and to find the suitable grille type and dimension for all applications. Product selection, room dimensioning and documentation search are easy available directly on web and mobile devices. Find this and much more on www.lindqst.com.
