Dayton 16-Inch Wall Collar

This galvanized steel wall collar is designed for 16-inch blade diameter fans in residential or commercial ventilation systems. It provides a finished mounting interface between the fan housing and the wall opening. The closed base construction helps direct airflow and seal the installation against drafts.

Verify Cut-Out And Depth Requirements

Confirm your wall opening measures 21 5/8 inches in both height and width to match the required cut-out dimensions. Ensure the mounting surface can accommodate the collar's overall depth of 12 1/2 inches within the wall cavity. The unit includes four mounting angles and four side panels for secure fastening to the structure.

Integrates With 16-Inch Fan Housings

The 20 1/4 inch overall height and width create a flush perimeter around the fan unit once installed. Galvanized finish resists corrosion in damp or exterior wall locations. The 20-gauge steel thickness provides rigid support without adding excessive weight to the framing. Mounting hardware is supplied for immediate installation.

Questions about this item

What comes with the Dayton 16D552 wall collar and what must be purchased separately?

The package includes four mounting angles and four side panels. The fan blade unit, motor assembly and any ducting are not included and must be sourced separately.

Which version of the Dayton 16D552 should I choose for a 16 in blade diameter?

This model is built for a 16 in blade diameter with a 20 1/4 in overall height and width, so select it when your rough opening measures 21 5/8 in by 21 5/8 in.

What does the 20 1/4 in overall dimension mean once the collar is installed in the wall?

The 20 1/4 in height and width are the finished flange size that sits flush against the wall surface, requiring a 21 5/8 in square cut-out for proper fit.
