Roll down grilles, rectangular, made of aluminium, for supply and extract air. For covering trenches for heating, underfloor induction units, decentralised ventilation units, light wells, overflow grating surrounding swimming pools and similar openings.

Ready-to-install component which consists of fixed transverse blades resting on two connecting strips with anti-vibration elements, available as a roll or as cut sections. Rolls come with a special tool for cutting to length. The covering of the blade cut edges prevents injuries and ensures that the grille is both quiet to walk on and flexible enough to be removed. Replacement of individual blades is possible.

Non slip characteristic and good optimum sound impact insulation due to rubber underside.
