About the Shoemaker SD34-0-20X6

This White 20" x 6" Shoemaker SD34-0 Series Vent Cover is designed to fit and cover a 20” wide by 6” high opening. Shoemaker has a complete line of products designed for homes, offices, stores, and many other commercial and residential applications. The quality and simplicity of this double deflection diffuser are only two of the many reasons why Shoemaker Manufacturing leads the field in innovative air-grille design for real world applications. The Shoemaker SD34-0 Series Spiral Pipe Diffuser (Double Deflection) is a transition box style spiral mount pipe diffuser. This diffuser is designed with a curved saddle that has a neoprene open-cell gasket for a tight seal. Its blades have nylon bushings for easy adjustment and quiet settings. The front louvers on this particular air-grille run parallel to the shortest dimension while the back louvers run parallel to the longest dimension. This diffuser is available in sizes that will fit spiral pipe diameters of 8” – 48”. (The spiral pipe’s diameter must be 4” larger than the width of the diffuser.) The Shoemaker SD34-0 Series vent cover comes with a recessed screwdriver-operated opposed blade damper. It is used to regulate the airflow through linked sections of adjacent blades that rotate in the opposite direction. Compared to other damper types, an opposed blade damper maintains a more even airflow. It also provides better control over the airflow in all operating positions. A recessed screwdriver-operated damper prevents any unnecessary adjustments of the damper setting. The standard color of this grille is soft white. Optional designer colors and aluminum paint finishes are also available. Unlike other products, Shoemaker grilles have a baked-on textured polyester powder coat that can resist scratches and does not wear or fade out easily. The Shoemaker Manufacturing Company leads the field in innovative air-grille design and it guarantees that its products are free from defective materials. Be sure to measure the hole opening size instead of measuring the face plate of your old grille. This grille is designed to fit over a 20" x 6" existing hole or duct. Refer to the Specification Sheet for more information.
