Product Details
The Galvanized Frame Wall Shutter (Rear Flanged) Model 556 is designed for areas where corrosion may be a concern, featuring a frame constructed from galvanized steel and blades made of mill finish aluminum. Each blade includes a galvanized reinforcement strip across the top for enhanced strength and counterbalancing efficiency, while a felt seal on the leading edge ensures quiet closure and improved weather protection. This shutter is ideal for use with both direct-drive and belt-driven exhaust fans and is recommended specifically for vertical mount exhaust applications.
