Width Limitations For Vent Covers

Width Limitations For Floor Vent Covers

Our grilles are made of high-quality, extruded aluminum.

While we are able to make almost any size of custom grille, we do have some limitations for floor and wall applications for product stability and safety reasons.

For floor grilles: we limit our floor grilles to 72 inches long for one single piece and 8 inches wide to maintain stability in the construction of the product.
