Shoemaker has earned their reputation as a manufacturer by making quality solutions.
The Shoemaker 901-0 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. 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 10" existing hole or duct. Refer to the Specification Sheet for more information.
