Dayton 1WBV5 Wall Collar 48 in Blade 54 1/4 in H Galvanized Steel

Dayton 1WBV5 Wall Collar for 48 in Blade

The Dayton 1WBV5 is a galvanised steel wall collar designed to fit a 48 in blade diameter. It provides a closed-base mounting frame for industrial or commercial ventilation installations. The unit measures 54 1/4 in overall height and width with a 23 1/2 in depth. Four mounting angles and four side panels are included for assembly.

Replaces worn or missing collars on 48 in units

This collar serves as a direct replacement when the original housing has corroded or been damaged. The upgrade is worth it when the existing cut-out matches the 55 5/8 in height and width dimensions. Galvanised finish and 18 ga steel thickness restore structural rigidity around the fan opening. No other blade sizes are compatible with this specific model.

Verify cut-out and depth before ordering

Confirm that the wall opening measures 55 5/8 in by 55 5/8 in to accept the flange. Ensure the available mounting depth accommodates the 23 1/2 in overall projection. The included hardware suits standard angle mounting; special brackets are not supplied. Buyers needing a different blade diameter or a non-galvanised finish should select another product.
