Triangle Engineering 61 Inch Double Panel Supply Shutter

The Triangle Engineering 61 Inch Double Panel Supply Shutter is built to last. Its frame gets a solid weld using galvanized steel, giving it some serious muscle. Inside, bronze pivot bushings help everything move smoothly for a good long while. The blades themselves are made from extruded aluminum, which is pretty neat for letting air flow through without a fuss. Plus, the whole thing sports a tough powder-coated frame that stands up well against rust and rough weather. This shutter is a dependable choice for your ventilation needs.
