Purpose and fit
The Dayton 53DR16 backdraft damper fits a 12 in fan and requires a 14-1/2 in by 14-1/2 in wall opening. It is intended for installers who need gravity-operated airflow control in vertical wall-mounted shutter applications.
Build and daily implications
An extruded aluminum frame with G-90 galvanized tie rods forms the 17 in by 17 in shutter, giving a free area of 0.927 sq ft and a frame depth of 2 1/2 in that opens to 5 3/4 in. The 1 1/2 in flange and 9/64 in mounting holes support secure wall attachment, while the vertical mounting position lets the damper open and close automatically up to 2500 FPM without power.
Pre-order checks
Confirm the rough opening measures exactly 14-1/2 in square and that the wall can accommodate the 17 in overall shutter size with the 1 1/2 in flange overlap. Verify the fan diameter is 12 in and that the installation orientation will be vertical, as the gravity mechanism depends on that position. Ensure the mounting surface accepts 9/64 in fasteners and that the 5 3/4 in open depth clears any interior obstructions.
