Door Grilles are manufactured of extruded Type 50S anodising grade aluminium which incorporates a set of inverted vee section vanes to ensure a vision proof assembly.
A matching telescopic flange is available for either standard or extra wide doors or partition. The grille is suitable for sidewall, door or partition mounting and is normally used for extract or air transfer applications. Typical installations include offices, shops, hotels, restaurants, schools and most commercial or industrial buildings. DO
