3-Way Stamped Face Steel Air Vent Cover - 11.75 X 9.75 Dimension

Register for Sidewall or Ceiling Applications: HBW Stamp Faced

The size listed, 10" W x 8" H, is for the measurement of the duct opening only. The actual overall dimensions outside are 11.75" wide by 9.75" high.

Difference between Grilles, Registers, Diffusers, and Vents: - Grille: a set of deflectors shaped like blades or fins fixed within a frame to allow air to pass from the duct to the room. - Register: a grille attached with a damper or valve for controlling airflow volume. - Diffuser: a unit with a duct connecting piece and a larger face piece with multiple blades for spreading out airflow in various directions (e.g. drop ceiling T-bar diffusers, round ceiling diffusers).

Size Selection Guide: Measure the size of the air duct opening (the "hole") and select the listed size that matches the opening size. The outside dimensions are 1.75" larger in both width and length to cover the hole. Do not use outside measurements for size selection.

The listed size of 10" x 8" is for the inside duct opening measurement, with the actual outside dimensions being 11.75" x 9.75".

Features: - Stamped face steel construction with 1/2" fin spacing for high airflow. - Three-way air flow deflection design. - Multi-shutter damper with an easy handle for adjusting the desired airflow. - Individually shrink-wrapped with a cardboard pad on the back for extra protection.
