This 18"x 4" Shoemaker 931-0 Steel Blade Single Deflection Diffuser Opposed Blade Damper is equipped with adjustable steel blades parallel to the longest dimension. It has nylon bushings for easy adjustment and quiet setting of the steel blades. It is a single deflection surface mount diffuser that allows 2-way air deflection on one plane. It comes equipped with a recessed opposed blade damper operated by a screwdriver. A recessed screwdriver-operated damper limits unnecessary movements of the damper setting. It is designed with countersunk mounting holes for a flush appearance with color-matching Phillips posi-drive screws. It is available in even sizes up to 36"x 36". Please see 901 Series for additional sizes. The quality and functionality of this damper are only two of the many reasons why Shoemaker Manufacturing leads the field in innovative air-grille design for real world applications. The Shoemaker 931-0 Series has a complete line of products designed for homes, offices, stores, and many other commercial and residential applications. Please measure the opening size instead of measuring the face plate of your old diffuser. Please note that this product is designed to fit over an 18"x 4" existing hole or duct. Please refer to the Specification Sheet for more information about this product.
