Updating the area that our return duct is, I wanted to get a replacement grille for it. Existing *grille* is 32" wide x 8" high. Looking at replacements (specifically AmeriFlows website) it says to size to the return *duct* size.
This is not a problem, but can I assume that the grille will have the same dimensions? The holes for the existing one are right near the edges of the grille, so I would need it to be very close to 32" wide or else I have plenty of drywall covering to do.
Thanks in advance!
