Product Details
The Galvanized Frame Wall Shutter (Rear Flanged) Model 556 is designed for environments susceptible to corrosion, featuring a frame made of galvanized steel and blades constructed from mill finish aluminum. Each blade is reinforced with a galvanized strip across the top to enhance strength and counterbalancing efficiency. Additionally, the blades are equipped with a felt seal on the leading edge, which ensures quiet closing and improved weather protection. This shutter is optimal for use with both direct-drive and belt-driven exhaust fans and is specifically recommended for vertical mount exhaust applications.
