This model is a rear flanged gravity supply (intake) wall shutter. The frame and blades are mill finish aluminum with a galvanized reinforcement strip on each blade for added strength and counter balancing efficiency. The blades have a felt seal on the leading edge for quiet closing and better protection from the weather. Ideal for use with belt-driven centrifugal wall ventilators. Recommended for vertical mount supply (intake) only. The blades will pivot at the bottom and fall with gravity to open. Spring-assist to close.
