Byson Gravity Grilles, Aluminum - Anodized

• The Byson Gravity Grille is designed to minimize backdrafts as well as ingress of water and snow
• Can be used in any application requiring permanent ventilation combined with screening such as air exhaust for ventilation or air conditioning systems, plant rooms, generators, workshops, garages and pumping stations
• The louvers are shaped and positioned to open with exhaust wind, and drop (close) with gravity, ideal for use on the external walls of a building at discharge points. These are not fixed louvres
• Made with high quality and attractive anodized aluminum - 2mm thick frame, 1mm thick louvers
• Provided sizing is for the "neck size", which is the size of duct and/or wall opening that the grille will be fit into

Installation

Self tapping screws (not included) can be used to drill directly into the grille face or neck, depending on preference, and fix it to the surface (wall or wooden frame) as required.
